Their acceptance by physicians, cosmetologists, and consumers contrasts with the few independent, well-controlled studies dem- onstrating long-term effects. Health care and cosmetic regulations differ among countries, although skin biology is the same throughout the world. In general, physicians consider that the current legal deﬁnitions of drugs and cosmetics are archaic and un- workable in some countries. It is evident that any environmental threat and top- ical product may exhibit some biological effect on the skin. This is a matter of deﬁnition because bioactivity dif- fers by several degrees of magnitude among product categories. There is a huge difference between decorative, supplement, and real active compounds in cosmetology (1). The term was coined by Kligman to describe products that fall between the two groups: cosmetics and pharmaceuticals. However, some corporate leaders contend that cosmeceuticals are neither scientiﬁcally sensible nor juridically nec- essary. In fact, with the exception of Japan, national regulatory agencies have not formally recognized the class of cosmeceuticals, or ‘‘quasidrugs. Some products are at risk of being banned, although they could be valuable in cosmetology; the reverse might also be true, and some products could be used in cosmetology without adequate evaluation of their potential biological effects. Many of these substances can be derived from natural sources and are often referred to as fruit acids. However, a number of synthetic sources provides access to new structural analogues. They are characterized into chemical groups based on the number of incorporated carboxylic groups (Table 1). The l-lactic acid is produced by the microorganism Lactobacillus and is responsible for the taste and odor of sour milk. The other enantiomer, d-lactic acid (also called sarcolactic acid) is formed during anaerobic muscular contraction and is also found in apples, ergot, foxglove, opium, and tomatoes. Mandelic acid (2-hydroxy-2-phenyletha- noic acid) can be obtained from hydrolysis of an extract of bitter almonds. Malic acid (2-hydroxy-1,4-butanedioic acid) was ﬁrst isolated from unripened apples in 1785. Citric acid (2-hydroxy-1,2,3-propanetricarboxylic acid) was ﬁrst isolated from lemon juice in 1784. During the past few years numerous cosmetics containing hydroxy- acids have appeared on the market with unfounded claims of performance. Erroneous information and incorrect statements ﬂourished behind promotional objectives obscuring the facts. At least one facet of the hydroxyacid biological activities may be ascribed to the native acid strength of the compounds. Such physicochemical characteris- tics are measured by the proton dissociation in solution and are expressed as the pKa. If the acid strength inﬂuences some of the biological effects of hydroxyacids, it does not, however, correlate with the potency of all their biological actions. The pH of the formulations varies with both the nature of the hydroxyacid and its concentration. In order to avoid irritation as much as possible, it is desir- able to formulate a cosmetic preparation with a pH close to the normal pH range of the skin. This may be achieved by partial neutralization and by the addition of an effective buffer. In order to prevent misunderstandings and misstatements about the effects of hydroxyacids, one should also consider biological actions related to their chemical structure regardless of their acidity. The exquisite enantioselectivity exhibited by many bio- logical systems suggests that enantiopurity is an important parameter in any phar- 38 Pierard´ et al. Thus the components of a racemate can differentially interact with biomolecules of the skin. Comedonal hyperkeratosis in acne-prone subjects might also be improved by the same compounds. In the ﬁeld of tumors, benign keratoses and viral warts may also be affected by high-concentration formulations. The effect of hydroxyacids, if any, on helioder- matosis appears more complex, involving multifaceted mechanisms boosting physiological aspects of aging skin. In the present review, we arbitrarily deﬁne the category low concentration when there is less than 4% of active compound in the formulation. Medium concentra- tion is applied in the range 4 to 12%, and high concentration for dosages higher than that. Their numbers normally decrease toward the surface of the skin, most notably during the stratum compactum to stratum disjunctum transition (2). In xerotic and ichthyotic conditions, ordered desquamation is impaired because des- mosomes persist up to the outer stratum corneum leading to the unruly accumula- tion of corneocytes and to skin scaling and ﬂaking (3). Although this compound at low and medium concentrations seems to have little or no effect on the normal stratum corneum, there is growing evidence that complete desmosomal degradation is helped in various xerotic and ichthyotic disorders (4–6). It appears, therefore, that applying the term keratolytic to such a compound is a misnomer, while desmolytic agent is more appropriate and explicit. Quite recently, a lipophilic derivative of salicylic acid was tested on normal human skin (6,7).
The kinetics of metabolism-dependent inhibition caused by metabolites that function as direct-acting inhibitors (e purchase 10 mg vardenafil visa. Therefore cheap 10 mg vardenafil amex, when further examination of such inhibition is warranted buy discount vardenafil 20 mg on-line, the inhibitory metabolite itself should be investigated. All of these designs offer certain advantages, but all have certain drawbacks as well, and most are intended to be used during drug discovery or early drug development. These may offer some advantages over fluorogenic substrates, but they have not been widely utilized (66,67) and appear more suited for screening during early discovery. Most of these substrates are not amenable to rapid analytical methods that make use of plate readers. Because of this limitation of chromatographic-based separations, several groups have developed radiometric assays based on radiolabeled conventional substrates, often with an extraction step, followed by scintillation counting (26,68–70). Test article interference is seldom a problem with radiometric methods, but their sensitivity varies with the specific activity of the substrate, which may necessitate the use of undesirably high protein concentrations and/or lengthy incubation times. In addition, radiometric methods are undesirable from a waste management per- spective. Two types of cocktail approach are used: one involves preincubation pooling of multiple marker substrates; the other involves postincubation pooling of multiple samples that were incubated with individual marker substrates. These problems are solved by incubating the marker substrates individually and pooling the samples after the incubations are terminated. However, a disadvantage of such postincubation pooling is that the samples become significantly diluted depending on the number of samples pooled. This controversy is partly because the principles of Michaelis- Menten enzyme kinetics (pure thoughts) are often applied to these (impure) systems. The advantages and disadvantages of each system are highlighted in the following sections. Another advantage is that the same sample of pooled human liver microsomes (and often the same experimental conditions, i. This is an important consideration because the enzyme that converts a drug to an inhibitory metabolite may not be the one that is inhibited (covered in detail below). A potential disadvantage of using pooled human liver microsomes is that these microsomes contain a large amount of lipid and protein that can decrease the free concentration of drug in the medium. However, to various degrees, this is a disad- vantage of all available in vitro systems. This disadvantage can be largely overcome by using highly sensitive analytical methods (e. Another potential disad- vantage is that human liver microsomes are an exhaustible resource; therefore, each batch of microsomes is slightly different, although the variability can be minimized by pooling samples from a large number of individuals and by preparing large batches with careful selection of individual samples. Indeed, when these measures are taken, pooled human liver microsomes may be one of the most consistent in vitro systems, with a well-designed pool lasting for four years or more (sufficient for 200 definitive studies, one per week or more). While the differences are sometimes artifacts of incubation conditions (especially those that are likely to violate the assumptions of the Michaelis-Menten equation), some differences appear to reflect genuine differences in the kinetics of reactions catalyzed by recombinant enzymes, purified enzymes, and human liver microsomes (Table 4). Constants are shown Æ standard m error (rounded to 2 significant figures, with standard error values rounded to the same degree of accuracy as the constant), and were calculated using GraFit software, which utilized rates of product formation (triplicate data) at 13 substrate concentrations. The cause of this difference remains unclear, but it was postulated that it reflects differences in the access of diclofenac to an effector-binding site or differences in active site conformation. The Ki values in Supersomes were found to be within a factor of 3 of the values for human liver microsomes with the exception of fluvoxamine, ketoconazole, and piroxicam (in which case the Ki values were 9-, 5. Ki values can also be estimated in vivo, but the study design is more involved than that typically used to evaluate the inhibitory 268 Ogilvie et al. In vivo Ki values can be determined in animals because it is possible to infuse a victim drug directly into the hepatic portal vein to accurately determine clearance, and subsequently to administer a wide range of bolus intravenous doses of a perpetrator drug in order to achieve a range of steady- state plasma concentrations. This approach was used in rats to determine that omeprazole inhibits the metabolism of diazepam with an in vivo Ki value of 21 mM (95), which is comparable to the in vitro Ki value determined in both rat liver microsomes and rat hepatocytes by a variety of experimental approaches (e. Furthermore, human hep- atocytes do not offer many of the advantages afforded by human liver microsomes. In contrast to human liver microsomes, human hepatocytes are difficult to pool in sufficiently large quantities to permit a detailed analysis of the kinetics of each marker substrate. In hepatocytes, a portion of the metabolite formed from various maker substrates may be conjugated, which further complicates the analysis of enzyme kinetics. It is not practical to prepare a pool of human hepatocytes that might support inhibition studies for a year or more, which can easily be accomplished with pooled human liver microsomes. Finally, in contrast to the situation with microsomes, cell viability is an issue with hepatocytes. In addition to being plagued with the same problems as noted for isolated hepatocytes, liver slices cannot be pooled, and even precision-cut liver slices (*20 cells thick) present a barrier to drug, metabolite, nutrient, and oxygen diffusion. It is possible, there- fore, that an inhibitor may not reach the same cells as those reached by the marker substrate, which will lead to an underestimation of inhibitory potential (102). Reactions can be terminated with an appropriate volume (usually an equal volume) of an organic solvent that is compatible with the analytical method to be used. In an automated system, it is most convenient to include the internal standard (preferably deuterated forms of the marker metabolite) at an appropriate concentration in the stop reagent. As mentioned in previous sections, microsomal protein concentrations and incubation times must be chosen in such a way that initial rate conditions are achieved and nonspecific binding to microsomal protein and lipids is minimized. The use of nearly uniform incubation conditions mini- mizes interassay differences in drug candidate metabolic stability and non- specific binding. The use of highly sensitive analytical methods also allows for a short incubation time with marker substrate (e. A similar effect is observed with long substrate incubation times when the drug candidate is rapidly converted to less 270 Ogilvie et al. In Vitro Study of Drug-Metabolizing Enzymes 271 inhibitory metabolites (inhibitor depletion). For Ki determinations, a common substrate concentration scheme is Km/3, Km,3Km,6Km, and 10Km. Assuming that the Km for the reaction has been accurately determined, this range of substrate concentrations will provide an adequate spread of data on an Eadie- Hofstee plot to readily observe the mechanism of direct inhibition. In such cases, it becomes necessary to choose alternate concentrations so that no fewer than five concentrations are used in a Ki determination. The choice of inhibitor concentration should ideally be based on known or anticipated plasma or hepatic concentrations of the drug candidate. The highest concentration examined in vitro should be at least 10-times higher than the maximum in vivo plasma concentration, and it is not uncommon to use a maximum in vitro concentration that is 100-fold higher. When such in vivo concentrations are not known, it is typical to use in vitro concentrations ranging from 0. Many drug candidates (and even some marker substrates) tend to have poor aqueous solubility at physiological pH. Regardless of the assay, each experiment should include a no-vehicle control (no-solvent control) and a vehicle (solvent) control to assess the effect of the solvent under the conditions of a given exper- iment. The effect of the drug candidate is compared against the appropriate vehicle (solvent) control.
Use an alligator clip to connect the free end of the other 1KΩ resistor (by pin 3) to the bolt buy cheap vardenafil. Connect the minus end of the battery (black wire) to the grounding bolt with an alligator clip purchase 10mg vardenafil overnight delivery. Connect the plus end of the battery (red wire) to the free end of the switch using a microclip lead discount vardenafil 20 mg with mastercard. Finally replace the lid on the box, loosely, and slip a cou- ple of rubber bands around the box to keep it securely shut. Zap for 7 minutes, let go of the handholds, turn off the zapper, and rest for 20 minutes. The best way to test your device is to find a few invaders that you currently have (see Lesson Twelve, page 492, or Lesson Twenty Seven, page 509). However, there is another way to make a zapper if you can not afford to build the first model. It is the positive voltage that eliminates so many parasites at once, not a specific frequency. That is because your resistance to the current starts going up right away, so less and less current passes through you. Capacitors only take part in the flow of electricity when they are charged and discharged. Tapping the terminal starts and stops the voltage so capacitors charge and discharge. The faster you tap, the greater the frequency of current pulses and the lower this kind of resistance becomes. Remember to take an intermission of twenty minutes and then repeat to avoid catching new viruses. Wrap each handhold with 9 volt battery one layer of wet paper 2 short (12”) alligator clip leads (from towel. Place each on a any electronics shop) 2 copper pipes, ¾” diameter, 4” long non-conductive surface, (from a hardware store) like a plastic bag. Connect the positive battery terminal to one handhold and the negative terminal to the other handhold using alligator clip leads. When you get tired pick up the left handhold with your left hand and tap with your right hand. Connect positive termi- nals of the batteries to each other, and the negatives also. Everything liv- ing on you or in you, not just to perch, but to take its food from you is a parasite. But in some way the big worms need to be distinguished from the medium-sized amoebae, the even smaller bacteria and the smallest of all—viruses. Roundworms are round like earthworms even though they may be as thin as hairs (threadworms, filaria) or micro- scopically small (like Trichinella). They have a way to attach themselves sometimes with the head (scolex) like tapeworms, sometimes with a special sucker like flukes. Worms Flatworms Roundworms Tapeworms Flukes Threadworms Pinworms Hookworms Worm parasites go through stages of development that can look very, very different from the adult. The favorite organ for Dirofilaria (dog heartworm) is the heart (even human heart). My tests show Dirofilaria can live in other organs, too, if they are sufficiently polluted with solvents, metals and other toxins. If you are a meat eater, you could eat such a cyst if it happens to be lodged in the meat you are eating! The little larva is swallowed and tries to attach itself to your intestine with its head. They come out of their metacercarial cyst as a small adult and quickly attach themselves to the intestine with a sucker. Four common flukes are: human intestinal fluke, human liver fluke, sheep liver fluke, pancreatic fluke of cattle. Has cilia, can swim vigorously and must find intermediate snail host in one to two hours or may be too exhausted to in- vade. Those are "mother" redia, and each one bears "daughter" redia for up to 8 months, all still inside the snail, and living on the fluids in the lymphatic spaces. If the snail is feeding on a plant, cercaria can latch onto plant with sucker mouth and start to encyst (form a "cocoon") within minutes. But as you eat the plant it is stuck to, the least pressure will break it, leaving the cyst in the mouth. The "almost unbreakable" inner cyst wall protects it from chewing, and the keratin-like coat prevents digestion by stomach juices. However when it reaches the duodenum, contact with intestinal juices dissolves away the cyst-wall and frees it. It then fastens itself to the intestinal lining and begins to develop into an adult. Note that the adult is the only stage that “normally” lives in the human (and then only in the intestine). Fasciolopsis depends on a snail, called a secondary host, for part of its life cycle. If propyl alcohol is the solvent, the intestinal fluke is invited to use another organ as a secondary host—this organ will become cancerous. If xylene (or toluene) are the solvents, I typically see any of four flukes using the brain as a secondary host. I call the diseases caused by fluke stages in inappropriate locations Fluke Disease; it is discussed in more detail later (page 249). Pollutants can invade your body via the air you breath, the foods and beverages you eat, and the products you put on your skin. The one who did not assumes the cream is not harmful to them…that they are like a bank vault, impreg- nable to that product. A better assumption is that the face cream is somewhat toxic, as evidenced by the rash that can develop, and they escaped the rash only because they had a stronger im- mune system. The immune system is like money, paid out of the bank vault, for every toxic invasion. Most other solvents dissolve fats and are life threatening, because fats form the membrane wall around each of our cells, especially our nerve cells. Metal Pollution Biochemists know that a mineral in raw element form always inhibits the enzyme using that mineral. Inorganic copper, like you would get from a copper bottomed kettle or copper plumbing, is 3 carcinogenic. We put metal jewelry on our skin, eat bread baked in metal pans, and drink water from metal plumbing. Mercury amalgam fillings, despite the assurances of the American Dental Association, are not safe. And sometimes the mercury is polluted with thallium, even more toxic than mercury! Gold and silver seem to have fewer harmful effects, but no one should have any pure metal in or on their body.
The agent order 10mg vardenafil amex, either as the fluid extract discount vardenafil 10 mg line, or from two to five grains of the resinoid purchase online vardenafil, is a most efficient partus accelerator. It increases the expulsive pains in a regularly intermittent and normal manner, without spasmodic irritation. While the normal pains are increased, all erratic, rheumatic, irregular and nagging pains are relieved. Knox observed the action of this remedy as a partus preparator in a hundred and sixty cases. His observations, summed up, are that the remedy has a positive sedative influence upon the parturient women, quieting reflex irritability, nausea, pruritis and insomnia. It has a positive anti-spasmodic effect, correcting neuralgic cramps, and irregular pains of the first stage of labor, sometimes terminating the labor precipitately, if given in too large doses, often without prodomic symptoms. Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 124 It relieves undue irritation of the uterine muscular fiber, relaxes the soft parts of the parturient canal, and thus facilitates labor and diminishes the risks of laceration by controlling undue irritability of the muscular fiber. It maintains a better contraction of the uterus after delivery, but for this purpose he administers a special dose of thirty minims of the fluid extract after the birth of the fetal head. It was his habit in using this remedy for its preparatory effects, to give fifteen minims, at the time of retiring each night, for six weeks prior to confinement. Coffin used this remedy for the above purpose, there was postpartem hemorrhage, and this caused the doctor to question whether or not the agent had such a relaxing influence, as he was not in the habit of giving either this or any other remedy to anticipate such hemorrhage. Webster claims to have observed a case of epilepsy, attended with amenorrhea which was kept under control with Cimicifuga in conjunction with the bromides, when the bromides alone had previously failed. The elder Adolphus, treated ophthalmia with this remedy, especially when there was severe pain. In the severe cases, he applied it externally, as well as administering it internally. In those cases where there was much nervous irritability, he combined it with gelsemium, which he was confident enhanced its influence. One of the old writers claimed that he used it persistently through an entire epidemic, and the results caused him to entertain the highest confidence in this remedy. If given with the appearance of the premonitory symptoms, the disease was so abridged, that no eruptions appeared. He usually gave it in the form of a decoction, in conjunction with equal parts of asclepias, and a small quantity of ginger. He gave enough of the remedy, to induce the physiological influence, such as aching in the muscles and pain in the head. The agent should have a further trial in this disease, as others have claimed to obtain results similar to those quoted above, and the influence of the remedy should be confirmed or disproved. Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 125 In the male it is valuable in gonorrhea, with aching, in the bladder and across the kidneys. It soothes the nervous irritability and materially assists in relieving the active inflammation. We usually find indications for aconite in the acute cases, or gelsemium where there is irritation with a tendency to spasmodic stricture, or hydrangea where there are sharp, cutting pains in urination; and these properly combined have been our “sure cure” treatment for many years, with mild injections of zinc sulphate, hydrastine, or hydrogen peroxide, all warm, or of warm water alone. In spermatorrhea with irritability and considerable sexual weakness and plethora, it will cure when other agents fail, if given in half-dram doses after meals. The pure alkaloids of cinchona are not employed in medicine, but their salts, formed from acid and basic combinations, are in common use. In the consideration of the therapeutic properties of the various alkaloids of cinchona there is but little difference observed in their action. There is almost no influence exercised by any one of them that is not exercised to an equal extent by quinine, and except where otherwise specified, the Sulphate. Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 126 Quinine Sulphate. Physiological Action—In doses of five grains three or four times a day for a few days, it produces fullness of the capillary circulation of the brain, throbbing in the head, suffusion of the face, ringing in the ears, with dullness of hearing, headache, mental confusion and nervous excitement. If the above doses be given every three hours continuously there is muscular feebleness, with general impairment of motility, increasing debility, great restlessness, with wakefulness, dilated pupils and partial loss of sight. A single dose of sixty grains of quinine sulphate, given to an adult male caused extreme depression, with feeble circulation, coldness of the surface and extremities, respiration slow and sighing; pulse slow and almost imperceptible, pupils widely dilated, sight and hearing almost extinct, voice very feeble; thirst great, tongue pale and moist, breath cold. While in some cases blindness from quinine has continued for some time in no case has it been permanent. In some cases death has followed the administration of the remedy in disease, a result fairly attributed to the drug. In small doses it is tonic, in large doses stimulant, and in still larger doses sedative, acting on the cerebro-spinal nervous system and through the ganglionic nervous system on the heart. Besides the above named effects, large and repeated doses may cause gastric irritation, eructations, chill and fever paroxysms headache, perspiration, vertigo, staggering and delirium— the condition known as cinchonism. Specific Symptomatology—Quinine will act favorably upon the system if the skin be soft, if the mucous membranes of the mouth are moist, and if the tongue is moist and inclined to clean, if the pulse is full and soft and the temperature declining or at normal. In other words, when the secretory functions of the body are in a working condition, quinine will produce no unpleasant results. It will overcome malarial periodicity, especially if the above named conditions are present when the agent is administered. It is profoundly tonic; under limited conditions it is antipyretic and also antiseptic. Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 127 Quinine destroys the plasmodium malariae readily, even in the minute quantity of one part to twenty thousand of water. Therapy—In the administration of quinine as an antiperiodic, the beneficial influences are not altogether in proportion to the size of the dose. Enormous doses may abort a chill if given during its course, or during the course of the fever. They are very likely, however, to increase the nervous erethism and the temperature; whereas, if proper doses be given during the intermission, from one to three hours preceding the anticipated attack, or at the time when the temperature has reached its lowest point, small doses will accomplish positive results. In continued fever, with a sufficiently marked remission occurring at a given time each day, or on each alternate day, the agent should be given during the remission, provided the temperature declines to a point sufficiently low to admit of a temporary restoration of the suspended secretions. As a result the temperature does not run quite as high as on the previous day, and the next remission is more marked and of longer duration. The fever is still lower and the remission so marked by the third day that the agent, in reasonable doses, may be continued through the exacerbation, the temperature at no time, probably, rising above 101 degrees and not increasing above normal after the third day. The writer has adopted this course for so many years, with perfectly satisfactory results, that the method is confirmed in his mind as the proper one in all cases where malaria is the cause, Where continued fever exists, quinine is of no benefit if there is no marked remission or other evidence of malaria. It is thus of no use during the progress of typhus, typhoid and other protracted fevers. In such cases it causes nerve irritation and increased temperature, especially if there is deficient secretion. When the fever is broken and there is a tendency toward a restoration of secretion, and the temperature is normal or subnormal, then this agent is a vitally important one. Here the bisulphate, being readily absorbed, Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 128 produces the happiest results. In intermittent fevers it is excellent practice to give the remedy in broken doses during the intermission.
Short-sightedness; he can see even small objects by holding them close to the eye 20 mg vardenafil overnight delivery, but the more distant the object is buy generic vardenafil 20mg on-line, the more indistinct it appears purchase vardenafil online now, and at a great distance he does not see it. Before his eyes there are floating as it were flies, or black points, or dark streaks, or networks, especially when looking into bright daylight. The eyes seem to look through a veil or a mist; the sight becomes dim at certain times. Painfulness of various spots in the face, the cheeks, the cheek-bones, the lower jaw, etc. Polypi of the nose (usually with the loss of the power of smelling); these may extend also through the nasal passages into the fauces. When the pain is still more unbearable and at times combined with a burning pain, it is called FothergillÕs pain in the face. Looseness of the teeth, and many kinds of deterioration of the teeth, even without toothache. She cannot remain in bed at night, owing to toothache On the tongue, painful blisters and sore places. Sensation of dryness of the whole internal mouth, or merely in spots, or deep down in the throat. Frequent mucus deep down in the throat (the fauces), which he has to hawk up and expectorate frequently during the day, especially in the morning. Frequently inflammation of the throat, and swelling of the parts used in swallowing. Bad smell in the mouth, sometimes mouldy, sometimes putrid like old cheese, or like fetid foot-sweat, or like rotten sour kraut. Eructations, empty, loud, of mere air, uncontrollable, often for hours, not infrequently at night. Incomplete eructation, which causes merely convulsive shocks in the fauces, without coming out of the mouth. Heartburn, more or less frequent; there is a burning along the chest, especially after breakfast, or while moving the body. Frequent sensation of fasting and of emptiness in the stomach (or abdomen), not unfrequently with much saliva in the mouth. Ravenous hunger (canine hunger), especially early in the morning; he has to eat at once else he grows faint, exhausted and shaky, (or if he is in the open air he has to lie straight down). Appetite without hunger; she has a desire to swallow down in haste various things without there being any craving therefor in the stomach. A sort of hunger; but when she then eats ever so little, she feels at once satiated and full. When she wants to eat, she feels full in the chest and her throat feels as if full of mucus. Want of appetite; only a sort of gnawing, turning and writhing in the stomach urges her to eat. Repugnance to cooked, warm food, especially to boiled meat, and hardly any longing for anything but rye-bread (with butter), or for potatoes. Pressure in the stomach or in the pit of the stomach, as from a stone, or a constricting pain (cramp). Pain in the stomach, as if sore, when eating even the most harmless kinds of foods. Pressure in the stomach, even when fasting, but more from every kind of food, or from particular dishes, fruit, green vegetables, rye-bread, food containing vinegar, etc. After the slightest supper, nocturnal heat in bed; in the morning, constipation and exceeding lassitude. After meals, pressure and burning in the stomach, or in the epigastrium, almost like heartburn. With some the anguish is aggravated after eating, even to an impulse to destroy themselves by strangulation. The flatus does not pass off, but moves about, causing many ailments of body and of spirit. Sensation as if the flatus ascended; followed by eructations - then often a sensation of burning in the throat, or vomiting by day and by night. Cutting pains in the abdomen, as if from obstructed flatus; there is a constant sensation of fullness in the abdomen - the flatus rises upwards. Cutting pains in the abdomen almost daily, especially with children, oftener in the morning than in other parts of the day, sometimes day and night, without diarrhoea. Cutting pains in the abdomen, especially on the one side of the abdomen, or the groin. From the small of the back, around the abdomen, especially below the stomach, a sensation of constriction as from a bandage, after she had had no stool for several days. Pain in the liver, a pressure and tension-a tension below the ribs on the right side. Below the last ribs (in the hypochondria), a tension and pressure all over, which checks the breathing and makes the mind anxious and sad. Constipation; delayed stools sometimes for several days, not infrequently with repeated ineffectual urging to stool. Stools hard, as if burnt, in small knots, like sheep-dung, often covered with mucus, sometimes also enveloped by veinlets of blood. Painless and painful haemorrhoidal varices on the anus, 1 the rectum (blind piles). Bleeding haemorrhoidal varices on the anus or in the rectum 3 (running piles), especially during stools, after which the haemorrhoids often pain violently for a long time. With bloody discharges in the anus or in the rectum, ebullition of blood through the body and short breathing. Formication and itching formication in the rectum, with or without the discharge of ascarides. He cannot hold the urine for any length of time, it presses on the bladder, and passes off while he walks, sneezes, coughs or laughs. Frequent micturition at night; he has to get up frequently at night for that purpose. So also inflammation of the bladder from strictures of the urethra, and the fistula in vesica are always of psoric origin, though in rare cases sycosis may be complicated with the psora. During urination, burning, also lancinating pains in the urethra and the neck of the bladder. Discharge of prostatic fluid after urination, but especially after a difficult stool (also almost constant dripping of the same). Nocturnal pollutions, even if not frequent, yet immediately attended by evil consequences. The semen is not discharged, even during a long-continued coition and with a proper erection,4 but it passes off afterward in nocturnal pollutions or with the urine. One or both of the testicles chronically swollen, or showing a knotty infection (Sarcocele).
Often the elderly prefer it this way in order not to bother with pill taking at meal time discount 20 mg vardenafil with amex. When the brain problems are corrected for an elderly person buy generic vardenafil 10mg line, be sure to relate the improvement to him or her buy discount vardenafil on line. This encourages the elderly, letting them know their existence and quality of life is important to you. Enjoy each bit of progress; it is often too subtle for your loved one to notice even when it is glaringly obvious to you. Before and after a chelation treatment can show a dramatic change in mood, energy, appetite and communication ability, yet get no comment from your loved one. They dare not talk about it because it is too painful a subject for the loved ones. And the immediate problems are too pressing to allow much contemplation of future problems. Surgically shortening the bands that hold the bladder in position (called bladder “lifting”) can give temporary relief, but the surgeon may be the first to tell you that it is a temporary fix. Still, it is so shocking not to be able to run a few steps or sneeze or cough without wetting the underwear, that anything seems better than doing nothing. Low potassium levels (due to excess potassium losses by the adrenals) causes more weakness. When you kill bacteria (and Schistosomes and Ascaris and other para- sites that bring in bacteria) and blood potassium levels go up, the problem is solved. Whether you have killed bacteria permanently determines whether you have permanently cured the condition. Tyramine is a bacterial by product that is quite toxic; it is rather high in aged cheese, also. With the food bacteria, Salmonellas and Shigella, out of the way and parasites being killed regularly, you can focus attention on the adrenals which control potassium levels. Mixing potassium salt with regular salt, half and half, for the shaker is another easy trick, even if you only use it in cooking where the taste cannot be detected. Potassium by prescription is often used by clinicians to conserve body potassium during diuretic use. This need not be stopped (if the pills are not polluted) although taking potassium pills is less useful than salting it in because the adrenals will let any big dose escape anyway. To facilitate getting to the commode quickly in the night, dress the elderly in a short night shirt, no pajamas or long gown. Wash the body parts daily, around the urinary and rectal outlet, using borax water. Nothing, not even brain improvement, impresses and encourages an elderly person as much as seeing the incontinence lessen. They would rather not go to church nor visit a friend than embarrass themselves in that way. Chewing It all begins with the stomach although chewing food well is essential for really good digestion. Such toxins lower the immunity of the mouth and throat and stomach since it all flows down into the stomach. If your elderly loved one has a red-looking mouth or throat, instead of pink, an infection is going on in spite of no coughs and no complaints. Repeat a third time to insure that any toxin found came from the dentures, not the saliva. Use 70% grain alcohol which you make yourself or plain vodka which is about 50% alcohol. Since alcohol evaporates and is expensive, use a wide mouth jar with close fitting non-metal lid for all this. Use food grade hydrogen peroxide or salt water to brush teeth in your mouth, never toothpaste. If you are responsible for this daily chore, use homemade floss (2 pound to 4 pound nylon fish line) first; then brush. If your loved one is seated they may be able to handle the brush by themselves, giving them pride in the achievement. Drinking water before meals stimulates it in unknown ways but is hard to do for the elderly. Using a lemon or vinegar and honey beverage helps with di- gestion although this provides citric or acetic acid, not hydro- chloric. The stomach becomes a haven for Salmonellas and other bacteria and this is the biggest digestive plague of the elderly. When they take over the region near the top of the stomach, it weakens the esophageal sphincter and food keeps coming back up a bit—a most uncomfortable development, especially after supper or when lying down. When the Salmonellas spread out further to invade the dia- phragm around the sphincter, the diaphragm weakens, and lets a bit of the stomach up through the hole. Leave them sitting at the table a while, then walk a bit, to get the food down lower. The food will sink lower if some of it can leave the stomach at the lower pyloric end. But if Salmonellas are entrenched here, too, the lower end does not have enough action to push the food through the valve. Coughing during eating is a sign that the diaphragm is irritated (by a hiatal hernia). Salmonella and Shigella Some Salmonella infections can bring dizziness to your eld- erly person. Feeling dizzy can make your loved one home bound and stuck to a walker for every move. Salmonellas, along with Shigellas, produce very toxic sub- stances that cause dizziness. Kill Salmonellas daily for a month by taking Lugol’s iodine (6 drops in a half cup water, after meals and bedtime, see Recipes). Unfortunately, this will not kill Shigellas; follow the Bowel Program (page 546) to get them. During this time set up a system of sterilizing all dairy products (see Milk, page 425) since this is the source of rein- fection. Set up a system of rinsing fingers (and fingernails) in 10% grain alcohol in the bathroom. A warm stomach full of food at a neutral pH is just the right culture condition for these bacteria. If your body has the right conditions (like a low acid stomach) to let them grow you dare not swallow another one! Shigellas arrive with dairy foods, too, but prefer the lower intestine as their headquarters. Besides getting digestive improvement you get mental improvement, less depression, less dizziness, less irritability after clearing these up. Other Clues Digestion problems that remain after eliminating bacteria can be diagnosed in a rational way. Ask these questions: • Is the stool orangish-yellow, or very pale, instead of greenish brown?
Estrogen hormone replacement therapy ± vitamin D also has proven valuable for slow- ing bone resorption in menopause order vardenafil toronto, and increases in bone mass have been reported for combinations of estrogens with alendronate proven 10mg vardenafil. Finasteride blocks the formation of dihydrotestosterone by inhibiting 5-alpha reductase and may be useful in both male pattern baldness and benign prostatic hyperplasia cheap vardenafil 10mg mastercard. Aromatase inhibitors tend to cause increased levelsof androgens, with excessivemasculinization as a side effect. Growth fraction Cytotoxic drugs are more effective against tumors that have a high growth fraction (large per- centage actively dividing). Colony-stimulating factors, erythropoietin, and thrombopoietin can be supportive --j J, infections and need for antibiotics. Other Dose-Limiting or Distinctive Toxicities Toxicity Drug(s) i Renal Cisplatin, * methotrexate i! Drugs that act on proliferating cells are cell-cycle specific and are usually also cycle-phase specific. Drugs that act on nonproliferating cells are dose dependent and cell-cycle independent. Rationales for combination drug usage are that each drug will independently killa fixed percentage and that one drug will still killa cancer cell that has developed resistance to a different drug in the cocktail. Bone marrow suppression often determines the upper limit of tolerable chemotherapy. A patient undergoing cancer chemotherapy has an increase in urinary frequency with much discomfort. Laboratory results include hematuria and mild leukopenia, but no bacteria or crystalluria. If the symptoms experienced by the patient are drug related, what is the most likely cause? After surgery for breast cancer, a patient is to undergo chemotherapy with a regimen that consists of cyclophosphamide, methotrexate, 5-fluorouracil, and doxorubicin. Which one of the following agents is most likely to be protective against the toxicity of methotrexate? Which anticancer drug, acting mainly in the G2 phase of the cell cycle, can cause blisters on the palms of the hands and soles of the feet and can make it difficult for the patient to breathe? Resistance to which anticancer drug, used mainly in childhood leukemia, is high in neo- plastic cells that have low activities of hypoxanthine guanine phosphoribosyltransferase? Bladder irritation with hematuria is a fairly common complaint of patients treated with cyclo- phosphamide. It appears to be due to acrolein, a product formed when cyclophosphamide is bioactivated by liver P450 to form cytotoxic metabolites. Urinary tract problems may also occur with methotrexate from crystalluria due to its low water solubility. All of the drugs listed are antimetabolites used in cancer chemotherapy or as immunosuppressants. Mercaptoethanesulfonate (rnesna), which inactivates acrolein, is available for protection against hemorrhagic cystitis in patients treated with cyclophosphamide and related drugs. It helps to know which anticancer drugs are cell-cycle specific and which have characteristic toxicities. Bleomycin fits both categories; acting mainly in Gz, it is cell-cycle specific and is distinctive for causing mucocutaneous reactions and pulmonary dysfunc- tion. Busulfan and procarbazine may also cause pulmonary toxicity, but neither drug is cell-cycle specific. Anti-D immunoglobin is given to Rh-negative mothers shortly after parturition to prevent hemolytic disease in future births. Which one of the following agents is paired correctly with its suggested clinical use and/or mechanism of action? Esmolol Theophylline, beta agonists I Ethanol, fomepizole Methanol or ethylene glycol Flumazenil Benzodiazepines, zolpidem, zaleplon Naloxone Opioid analgesics Oxygen Carbon monoxide Penicillamine Copper (e. Evidence supporting the clinical effectiveness of herbal products is commonly incomplete. Symptoms of iron poisoning in a 3-year-old child may include severe gastrointestinal distress with hematemesis, a shock-like state with marked dehydration and progressive hemorrhagic gastritis. Regarding the management of iron toxicity, which one of the fol- lowing statements is accurate? Which one of the following symptoms is most likely to be associated with lead poisoning? Gastric lavage should be attempted with care regarding aspiration, but changes in urine pH have no effect on the elimination of iron. The systemic absorption of many drugs taken orally can be reduced by activated charcoal; unfortunately, iron is not one of them. The profile of lead toxicity includes decreased heme synthesis, anemia, nephropathy, and peripheral neuropathy, the last leading to foot or wrist drop.
