With a resource like this purchase 40mg diovan free shipping, we hope that a major part of the process – admissions criteria – can become clearer for everyone generic diovan 160 mg mastercard. It was created by the Medical Schools Council and is updated yearly from informaton passed directly from the medical schools discount 40 mg diovan visa. The purpose of the guide is to act as a point of reference and easy comparison for entry requirements. It cannot contain the full details of each medical school’s requirements, so seeking confrmaton and additonal informaton on individual medical school’s websites is essental. Diversity and ‘widening partcipaton’ “I’ve had to overcome This guide will be useful to all who are considering an some major adversities applicaton to study medicine. It was, however, created in life in order to be with partcular focus on ‘widening partcipaton’. I’m extremely happy to Factors like wealth or cultural background should not have been given the be a barrier to studying medicine. University of Southampton Part of this is to present entry requirements informaton in the clearest way. It will also help careers advisers ensure that their knowledge is correct and up to date. Collatng and publishing this informaton is part of the medical schools’ response to the demand for clear and accessible entry requirements for medicine, as recommended in the Final Report of the Selectng for Excellence project. Graduate Entry Medicine This is open to applicaton from those who already have a bachelor’s degree. Many universites accept a degree in any subject, but some require the previous degree to be science- or health-related. It is a four- year accelerated degree in most cases, but in some universites it is a fve-year course. Medicine with a Preliminary Year Note → This course takes the form of either a fve-year Standard Entry Medicine with an additonal year at the start, Sometmes this course is making a six-year course, or sometmes the preliminary called a ‘foundaton year’. It should not be confused with the Foundaton This course is designed for those who achieved highly at Programme, which is the A level, or equivalent, but who did not take the required period of practcal training science subjects. It is not a means of boostng the grades of those who do not meet the entry requirements of Standard Entry Medicine. Medicine with a Gateway Year These medical degrees are designed for those who are Note → of high ability but who may be coming from situatons These courses have been where they have had barriers to their learning. Applicants may sit diferent combinatons of these tests according to the medical schools they intend to include in their applicaton. The score is then sent automatcally to the relevant medical schools on the applicaton. It is also used for graduate applicants to a small number of Standard Entry Medicine courses. This means that there are many diferent Access courses on ofer, though ofen they are designed for mature learners who may not have A levels or equivalent. As is the case for Medicine with a Preliminary Year, Access courses are not a supplement for poor performance at A level. If you are thinking about applying for a specifc Access course, it will be useful to frst check some things with medical schools and with the insttuton ofering the Access course in order that you can feel comfortable with your decision. Questons for medical schools • Do you accept the qualifcaton ofered by this Access course as part of your entry requirements? Questons for the Access course provider • Have students who have taken the Access course gone on to study medicine? They state the number of applicants per interview and the number of applicants per place on the course. It is at the following stages, such as interview, where medical schools really start to diferentate the applicants. Most medical schools do not score the personal statement (but may stll read it for background informaton). The key is the way in which an applicant discusses their experiences in the interview, not the places where they have gained them. For instance, if asked to provide an example of working with other people, having had a part-tme job can be just as valuable for answering this as having shadowed a doctor. This can take many forms, from statng partcular colleges that the medical school works with, to describing how the grade threshold may be lowered according to factors in the applicant’s circumstances. A combinaton of grades A and B especially in science subjects and minimum grade C in English and Maths. Three subjects at Higher level at grade 6 or higher including Internatonal Baccalaureate Chemistry and one of either Biology, Physics or Maths. Work experience in hospital or primary care; volunteering in nursing homes, hospices etc; talking to medical students/doctors about their Work experience studies/job; atending university events about medicine.

Applicants may be eligible for a contextual ofer if applying from a school or college ranked in the botom 40% in any of the following categories: average score per A level entry; average score per A level entrant; percentage of students applying to higher educaton. Widening partcipaton Contextual ofers are usually two grades lower than the standard ofer. For internatonal baccalaureate this may be 32 points overall with 16 at Higher Level, including 6 at Higher Level in Chemistry and 6 at Higher Level in another lab-based science. Applicants must have A level passes in Chemistry and two of Biology/Human Biology, Physics, Mathematcs. Personal statement Personal statement is reviewed prior to interview but not scored. The medical school is not prescriptve about how this is obtained and recognises the widely difering opportunites available. General Studies, Highers Critcal Thinking and Further Mathematcs are not accepted. Minimum of 19 points must be achieved in Higher level Internatonal Baccalaureate subjects. Non-academic criteria assessed; medical motvaton and awareness of the career, sense of responsibility, evidence of a balanced approach to life, Personal statement evidence of self-directed learning and extracurricular actvites, caring ethos and a sense of social awareness, referee’s report. The university recognises that opportunites for work experience will vary according to individual circumstances. Applicants are to showcase Work experience an appreciaton of the length of the training programme and the career structure. The academic and non-academic atainment of a candidate will be reviewed against educatonal performance data and socio-economic background to provide an overview of an applicant’s potental.

Chemistry and one other Internatonal Baccalaureate science (Biology preferred) at Higher Level.

Although this characteristic is useful when trying to mimic the metabolic char- acteristics of an organ buy diovan 80mg cheap, it is a drawback when trying to characterize the kinetic constants of an individual P450 enzyme or when trying to determine which enzyme is involved in the metabolism of a particular drug order diovan 80mg free shipping. Because of the generally broad substrate selectivities of the P450 enzymes purchase 80 mg diovan, most observed metabolic reactions can be catalyzed by more than one enzyme. Interindividual variability in the content of the different P450s makes it even more difficult to determine the different kinetic parameters when more than one enzyme is involved in a given reaction. Preparations containing a single P450 isozyme are available as either expression systems or purified, reconstituted enzymes. The P450s have been expressed in bacterial, yeast, insect, and mammalian cells (8). However, in order to obtain adequate enzyme activity for most expression systems, it is necessary to supplement the membranes with reductase and in some cases cytochrome b5. This is accomplished by either supplementing the membranes with purified coenzymes or by coexpression of the coenzymes. Alternatively, the P450 enzymes can be purified and reconstituted with coenzymes into artificial membranes. Micro- somes may more closely represent the in vivo activity of a particular organ, but kinetic analyses are complicated by the presence of multiple enzymes. It is not possible to spectrally quantitate the content of any individual enzyme when a mixture of enzymes is present. Expression systems provide isozymically pure preparations, but they also have their disadvantages. The P450 enzymes are membrane bound, and for the nonmammalian expression systems the membranes may have different interactions with the P450 proteins. Although expression levels in most of the systems are adequate for spectral quantitation, coexpression of the coenzymes adds variability to different batches. However, the membranes are artificial and can have an influence on enzyme activity. Finally, these differences are further complicated by unpredictable influences of ionic strength, pH, etc. Incubation Conditions Enzyme kinetics are normally determined under steady-state, initial-rate con- ditions, which place several constraints on the incubation conditions. First, the amount of substrate should greatly exceed the enzyme concentration, and the consumption of substrate should be held to a minimum. This constraint ensures that accurate substrate concentration data are available for the kinetic analyses and minimizes the probability that product inhibition of the reaction will occur. This constraint can be problematic when the Km of the reaction is low, since the amount of product (10% of a low substrate concentration) may be below that needed for accurate product quantitation. One method to increase the substrate amount available is to use larger incubation volumes. For example, a 10-mL incubation has 10 times more substrate available than a 1-mL incubation. When more than 10% of the substrate is con- sumed, the substrate concentration can be corrected via the integrated form of the rate equation (Dr. James Gillette, personal communication): v Vm½SŠ ¼ ð3Þ Et Km þ½SŠ 0 ½SŠ0 À½SŠf S ¼ ð4Þ ln½SŠ0/½SŠf In Eq. S0 0 f approaches [S] when substrate consumption is minimal, and S0 is substituted for [S] to correct for excess substrate consumption. In these analyses, however, substrate inhibition can be a problem if the product has a similar affinity to the substrate. Fortunately, most P450 oxidations produce products that are less hydrophobic than the substrates, resulting in lower affinities to the enzymes. There are exceptions, including desaturation reactions that produce alkenes from alkanes (10) and carbonyl compounds from alcohols. These products have hydrophobicities that are similar or increased relative to their substrates. In the presence of reducing equivalents, the P450 enzymes will generally lose activity over time. Provided that the loss of enzyme is not dependent on substrate con- centration, the Vm of the enzyme will change, but not the Km. For P450 reactions, the presence of substrate in the active site can either protect the enzyme or increase its rate of deactivation. Enzyme stabilization can result in a sigmoidal saturation curve for an enzyme showing hyperbolic saturation kinetics, and enzyme destabilization can show substrate inhibition if the enzyme content varies over the incubation time. The reaction should also be linear with enzyme In Vitro Enzyme Kinetics Applied to Drug-Metabolizing Enzymes 37 concentration to ensure that other processes, such as saturable, nonspecific binding, do not alter the enzyme saturation profile. Analysis of Michaelis-Menten Kinetic Data By far, the best method of determining kinetic parameters is to perform an appropriately weighted least-squares fit to the relevant rate equation (11). Although reciprocal plots are useful for determining initial parameters for the regression and for plotting the results, initial parameters for a single enzyme showing hyperbolic saturation kinetics can be obtained by inspection of the data. Reaction Conditions In addition to the preceding complexities, the P450 enzymes have some unique characteristics that complicate the design of experimental protocols. Because of the broad substrate selectivities for these enzymes, the enzymes are not opti- mized for the metabolism of a particular substrate. To further complicate matters, the velocities for these enzymes tend to vary greatly with changes in these reaction conditions. This variation may well be due to the dependence of the reaction velocity on several pathways in the catalytic cycle. However, the actual rates of substrate oxidation are probably dependent on three additional rates: the rate of substrate oxidation and the rates of the decoupling pathways (hydrogen peroxide formation and excess water formation). Thus, the efficiency of the reaction plays a major role in determining the velocity of a P450 oxidation (16,17). The sensitivity of the reaction velocities to incubation con- ditions may be due to changes in the reduction rate as well as to changes in the enzyme efficiency. Although many P450 reactions show optimal activity in the pH range of 7 to 8, both chlorobenzene and octane metabolism show optimum activity at pH 8. This is also the pH at which P450 38 Korzekwa oxidoreductase optimally reduces cytochrome c. In addition, whereas essentially all in vitro metabolism studies are carried out at 378C, both these reactions occur much faster at 258C. Even the optimum ratio of reductase to P450 depends on the substrate and the enzyme. In contrast, essentially all reactions that have a cytochrome b5 dependence are saturated at a b5/P450 ratio of 1:1. Thus, many P450 oxidations show a substantial and variable dependence on reaction conditions, which makes it impractical to optimize each reaction. In fact, the optimum reaction conditions may not represent the in vivo reaction environment. It would be difficult to justify a reaction temperature of 258C in an experiment that will be used for in vitro–in vivo correlations. A more practical approach would be to use a consistent set of reaction conditions that provide adequate velocities. Most P450 oxidations show hyperbolic saturation kinetics and competitive inhibition between substrates. Therefore, both Km values and drug interactions can be predicted from inhibition studies. Competitive inhibition suggests that the enzymes have a single binding site and only one substrate can bind at any one time. For the inhibition of substrate A by substrate B to be competitive, the following must be observed: 1. Substrate A has a hyperbolic saturation curve: Enzymes that bind to only one substrate molecule will show hyperbolic saturation kinetics. However, the observation of hyperbolic saturation kinetics does not necessarily mean that only one substrate molecule is interacting with the enzyme (see discussion of non-Michaelis-Menten kinetics in sec. The presence of substrate B changes the apparent Km but not the Vm for substrate A: Saturating concentrations of A must be able to completely displace B from the active site. Complete inhibition of metabolism is achieved with saturating concen- trations of substrate B: Saturating concentrations of B must be able to completely displace A from the active site. Substrate B does not change the regioselectivity of substrate A: The regioselectivity of the enzyme is determined by the interactions between the substrate and the active site.

Acidifying this product with cyclopropan- carboxylic acid chloride and further reduction of the introduced carbonyl group gives N-cyclopropylmethyl-6 purchase 40 mg diovan otc,14-endoethano-7-(2-hydroxy-3 diovan 80 mg lowest price,3-dimethyl-2-butyl)-tetrahydronorthe- baine (3 discount diovan 40mg without a prescription. Buprenorphine differs from the other examined agonist–antagonists in that it exhibits a partial agonistic effect on the µ-receptors. It exhibits a number of certain unique effects that are not typical of compounds of this series. The efficacy and strength of opioid antagonists varies depending on the type of opioid recep- tors (µ-, δ-, κ-, σ-) with which they interact. However, it has been suggested that they antagonize the action of endogenous opioid peptides. They antago- nize the action of agonists, mixed agonists–antagonists, and they do not result in depend- ence or tolerance. They are used upon overdose of opioid analgesics or in the event of patient intolerance to them, and also in treating drug addiction. AnalgesicsAnalgesics It is worth mentioning that N-allylic substitution in a number of morphine derivatives, as a rule, leads to antagonistic properties. It eliminates central and peripheral action of opioids, including respiratory depression. One of the methods of synthesis is analogous to the synthesis of naloxone, which consists of using cyclopropylmethylbromide instead of allylbromide [59]. It is similar to naloxone in terms of pharma- cological characteristics; however, it differs in two important ways—long-lasting action and that its metabolite 6-β-naltrexol is also a strong antagonist. Naltrexone is used for blocking pharmacological effects of opioids upon their overdose. In addition, they are devoid of many undesirable effects that accompany opioid analgesics (respiratory depression, addiction, etc. They are called nonnarcotic analgesics, aspirin-like substances, anti-fever analgesics, etc. It is supposed that it might be connected with its ability to inhibit synthesis of prostaglandins, which reduces their sensitizing influence on nerve endings, which in turn reduces the effect of neurotransmitter action—bradykinin in particular. However, analgesic and anti-inflammatory activity of these drugs is not always correlated with their ability to suppress prostaglandins. There are other assumptions about the mechanism of action of nonnarcotic analgesics. Experiments in animals show that the analgesic action of this series of drugs is peripheral; however, it is possible that the acetaminophen may have a central action by blocking painful impulses. In general, nonopioid analgesics are characterized by three fundamental types of action: analgesic, anti-inflammatory, and fever-reducing action, which are used for alleviation of headaches, myalgia, arthralgia, and that do not have sedative or soporific effects. It is believed that the primary mechanism of action is the irreversible acetylation of cyclooxygenase, which results in the inability to synthe- size prostaglandins, prostacyclins, and thromboxane. As a result, the pyrogenic effect of prostaglandins on the centers of thermoregulation and sensitive nerve endings is reduced, which leads to a lessening of sensitivity to painful neurotransmission. The antiaggrega- tory effect of aspirin is explained by the irreversible inability to synthesize thromboxane A2 in the thrombocytes. Aspirin is widely used for head and neuralgic pains, rheumatic conditions, painful symp- toms of various etiologies, and eliminating painful feelings during menstruation. It is used in conditions such as fevers, prevention and treatment of thrombosis and embolism, and for prevention of ischemic abnormalities and cerebral blood circulation. This product is reacted with carbon dioxide in the presence of a base according to the Kolbe–Schmitt phenol carboxy- lation method, giving diflunisal (3. It is used for long- and short-lasting symptomatic relief of low to moderate pain in osteoarthritis and rheumatoid arthritis. In medical practice, other salicylic acid derivatives are used in the form of salts. Magnesium salicylate and sodium salicylate are less effective than respective doses of aspirin; however, they are easier on patients that are sensitive to aspirin. Choline magne- sium trisalicylate represents a mixture of choline salicylate and magnesium salicylate, which has the same effect as aspirin; however, it is easier on patients in which gastroin- testinal effects are observed upon taking aspirin. Among these are antipyrin, butadion, amidopyrin, phenylpyrazon, sulfinpyrazone, sodium methamizol sodium (analgin), and a few others. In terms of analgesic and anti-inflammatory action, they are similar to salicylic acid deriva- tives. Although the mechanism of their action is not completely known, it is supposed that pyrazolone derivatives, like aspirin, inhibit biosynthesis of prostaglandins and reduce per- meability of capillaries, thus preventing the development of inflammatory reactions. A serious limitation to the wide use of pyrazolonee in medicine is the cases of onset of agran- ulocytosis upon use of methamizol sodium. Nevertheless, the most widely used derivative in medicine is methamizol sodium (although it is prohibited in some countries) as well as combined drugs on its base; in par- ticular, baralgin, which represents a combined drug based on methamizol sodium with the spasmolytic 4′-(ethoxypiperidine)carbomethoxybenzophenone and the ganglionic blocker 2,2-diphenyl-4-piperidylacetamide. Metamizole sodium: Methamizole sodium, 1-phenyl-2,3-dimethyl-4-methylaminopyra- zolone-5-N-sodium methansulfonate (3. Methylation of this product with methyl iodide gives 1-phenyl- 2,3-dimethylpyrazolone-5 (3. This compound is used independently in medicine as a fever-reducing and anti-inflammatory analgesic under the name antipyrin. It undergoes nitrozation by sodium nitrite in an acidic medium, forming 1-phenyl-2,3-dimethyl-4- nitrozopyrazolone-5 (3. This product is reacted with benzaldehyde, forming an easily separable crystalline 1-phenyl- 2,3-dimethyl-4-benzylidenaminopyrazolone-5 (3. Hydrolysis of the resulting salt gives 1-phenyl-2,3-dimethyl-4-methylaminopyrazolone-5 (3. Treating the product with a water solution of a mixture of sodium bisulfite and formaldehyde leads to the forma- tion of 1-phenyl-2,3-dimethyl-4-methylaminopyrazolone-5-N-sodium methanesulfonate (3. Methamizole sodium is used for relieving pain of various origins (renal and biliary colic, neuralgia, myalgia, trauma, burns, headaches, and toothaches). Use of this drug may cause allergic reactions, and long-term use may cause granulocytopenia. It was recently shown that acetaminophen, like aspirin, inhibits cyclooxygenase action in the brain and is even stronger than aspirin. On the other hand, the mechanism of analgesic action of acetamin- ophen is not fully clear, since it acts poorly on peripheral cyclooxygenase. It is also effective like aspirin and is used in analgesia for headaches (from weak to moderate pain), myalgia, arthralgia, chronic pain, for oncological and post-operational pain, etc. The mechanism of action of this series of nonsteroid, anti-inflammatory analgesics is not conclusively known. It is frequently used in combination with the anticoagulant warfarin, the effect of which is strengthened when combined with flufenamic acid. Meclofenamic acid: Meclofenamic acid, N-(2,6-dichloro-m-tolyl)anthranylic acid (3. The mechanism of their action is not con- clusively known; however, it has been suggested that it is also connected with the suppression of prostaglandin synthetase activity. The simplest way to synthesize ibuprofen is by the acylation of iso-butylbenzol by acetyl chloride. Hydrolysis of the resulting product in the presence of a base produces ibuprofen (3. Ibuprofen exhibits analgesic, fever-reducing, and anti-inflammatory action compara- ble to, and even surpassing that of aspirin and acetaminophen. It is used in treating rheumatoid arthritis, in various forms of articular and nonarticular rheumatoid diseases, as well as for pain result- ing from inflammatory peripheral nerve system involvement, exacerbation of gout, neu- ralgia, myalgia, ankylosing spondylitis, radiculitis, traumatic soft-tissue inflammation, and in the musculoskeletal system. The most common synonyms for ibuprofen are brufen, ibufen, motrin, rebugen, and others. It causes reduction and removal of painful symptoms including joint pain, stiffness, and swelling in the joints. The carbonyl group of the resulting product is reduced by sodium borohydride and the resulting alcohol (3. Analgesics Fenoprofen is chemically and pharmacologically similar to the series of compounds described above. It is used in treating symptoms of rheumatoid arthritis and osteoarthritis; however, fenoprofen exhibits a number of undesirable side effects.

A case of chronic hematuria order diovan 40mg without a prescription, with sensation of weight and tension in the Ellingwood’s American Materia Medica order 160mg diovan with mastercard, Therapeutics and Pharmacognosy - Page 402 pelvis depending upon varicose conditions of the rectal veins 40mg diovan visa, was quickly relieved by it. Specific Symptomatology—Felter and Lloyd say that its indications are found in dull aching pain over the spleen, which passes up to the left scapula, associated with pronounced debility and despondency, splenic pain, with no enlargement or with enlargement, when there are no evidences of malaria. General bilious conditions accompanied with stitches in the right side, with hard and tender spots, in this locality, gall stone, jaundice, hepatic pain and swelling. As it overcomes congestion within the pelvis, it is useful in certain forms of dysmenorrhea, amenorrhea, or irregular passive uterine hemorrhages. Therapy—Harvey, in the California Medical Journal, says the indications are so plain that a tyro can prescribe it with certainty. It is indicated where there is venous stasis, the true veins enlarged and clogged with blood. He says he cured one case, where the veins from the hips to the toes were as large and as hard and twisted as Manila rope. There was a troublesome chronic cough with the expectoration of large quantities of offensive matter. He had observed these colored spots in other cases, and sometimes found long continued soreness and tenderness of the joints of the feet. Carduus, in five-drop doses three or four times a day, cured all the symptoms in this case, restoring the patient to perfect health. Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 403 Physiological Action—Mustard is emetic, stimulant and actively revulsive with marked anodyne properties. Its application to the skin produces intense burning, violent inflammation, and if persisted in too long, sloughing or ulceration. Taken into the stomach in large quantities, if emesis be not produced, it causes a burning sensation and a mild form of gastritis. Specific Symptomatology—For external application it is indicated in acute cutting pain local in character, usually intermittent and usually present as the result of rapidly developing acute inflammation, but dull, steady and constant pains or soreness, slowly developing and persistent, are not readily relieved by its application. Internally it is indicated to excite vomiting when non-corrosive poisons have been taken, when a foreign body is lodged in the esophagus, or when there is great distress from an overloaded stomach. Administration—In the use of mustard for counter-irritation, in cases of acute pain, it is desirable to obtain its sharp effects as quickly as possible. In order to do this, a fresh article should be procured, one in which the pungency is sharply indicated by its action on the nostrils and eyes, since mustard kept in a paper package on the shelves for weeks is inert from loss of the volatile oil. Vesication must be avoided, as the blisters thus caused are of no advantage, and exceedingly painful and difficult to heal. The white of an egg rubbed up with mustard and a little water, will produce a poultice which will not readily blister. When mild counter-irritation only is desired, which is to be prolonged for some hours, a poultice is made in the proportion of one part of mustard to four or six of linseed meal or flour. This is not, however, effective in acute pain, but only where there is soreness or prolonged distress. Vinegar and mustard also make a good poultice for prolonged use, as vinegar destroys an excess of activity of the mustard. For a hot mustard pediluvium, a tablespoonful of the powder is stirred into a gallon or two of hot water, in which the feet are immediately im. For a general mustard bath, two or three tablespoonfuls of mustard are mixed in a full bath. For a child one tablespoonful will be sufficient, care being taken to protect the eyes of the patient from the vapor. Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 404 Therapy—A teaspoonful of mustard in a bowl of warm water will produce active and immediate emesis. This should be followed by another bowl of warm water alone, which will continue the evacuation and wash out any remaining mustard, as even then the burning sensation from the local effects of this substance with a few patients is hard to bear. An emetic dose must not be allowed to remain in the stomach, as inflammation may follow. It does not seem to increase the tone of the gastro-intestinal canal, or promote the action of the secretory or excretory glands, or assimilative organs, to any great extent, but its external use is common. In the treatment of acute pleuritis a warm poultice applied over the affected side sufficiently large to much more than cover the diseased area, will usually relieve the pain at once, and a large poultice is always more effective than a small one. It may be necessary to repeat its application within twenty-four hours, but if vigorous direct treatment is adopted, this is seldom necessary. In bronchitis or pneumonitis in the initiatory stages, a quick poultice of mustard will exercise a good influence, but it does not give the immediate relief experienced in pleuritis or pneumonitis where acute pain is a prominent symptom. It should be followed, in the former conditions, as soon as the sensitiveness of the skin will allow, by persistent heat, moist or dry, as seems indicated. In acute pain in the heart, either in angina pectoris or from other cause a sharp mustard poultice is essential. In acute stomach pains and in intestinal colic, or pain in the abdomen from any cause, a large hot mustard poultice will be of much service. In all cases where mustard is used it is only auxiliary to other prompt treatment, as its influence is usually transient. A most efficient measure in congestive headache, or in headache from any cause with fullness of the cerebral vessels, is a mustard poultice on the nape of the neck. Spinal irritation is most effectively treated by the use of a succession of Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 405 these poultices. On the first day of the treatment one is applied on the back, across the upper third of the spine; on the second day across the middle third, and on the third day across the lower third, producing thorough sharp counter-irritation but no blistering. On the fourth day it is applied at the top of the spine again and the same course followed as before. This may be continued for two weeks or more if the skin is sufficiently restored in the interim, between the poultices. This course will most materially assist other measures adopted in the treatment of this condition. A hot mustard foot bath is of great service in congestive chill, also in the chill at the onset of acute fever, or acute inflammation of any character. It produces immediate derivation, assists in equalizing the circulation, acts as a diaphoretic and perceptibly checks the progress of the disease. In the recession of the rash of eruptive fevers no measure is more prompt than a general hot mustard bath, which should be continued until a mild redness covers the entire body. At the onset of acute cerebro-spinal meningitis the disease has been completely aborted by the prompt use of a hot mustard bath. In some cases the patient may be wrapped in a blanket wrung out of hot mustard water, until the skin is reddened. In conditions where there is a constant tendency for the skin of the legs to become cold, and the muscles to cramp during the night, a hot mustard foot bath at bedtime is of direct benefit. In arrest of the menses from cold, a sitz bath strong with mustard will sometimes produce an immediate restoration of the flow. It is sometimes necessary to take this bath each night for a week preceding the time the menses should appear and continue it until that result is obtained. Extractum Sarsaparillae Fluidum Compositum, Compound Fluid Extract of Sarsaparilla. Therapy—This agent is an active eliminant, possessing diuretic and alterative properties to a marked degree. It has long been a popular remedy for the treatment of blood dyscrasias, but is nearly always given in combination with other well known specific alteratives. In combination with potassium iodide, stillingia, corydalis, phytolacca, podophyllum, or other alteratives, it has been given in scrofula and secondary syphilis, and especially in cutaneous diseases depending upon blood dyscrasia, and in rheumatic and gouty conditions, with inactive kidneys irritated from the presence of large quantities of uric acid and the urates. It was used in an Eastern hospital for epileptics experimentally, with a reduction in the number of paroxysms of twenty- five per cent. It may be given in all forms of epilepsy in sufficient frequent doses to produce a sensation of dullness or drowsiness. It has been used in the treatment of puerperal convulsions with satisfactory results, in a few cases. Potatoes and tomatoes belong to this family, and although the fruit is edible, the vines are usually poisonous. Injected into the veins it causes dyspnea, thrombosis in the vessels and arrest of respiration. Toxic doses produce tremors, muscular contractions, central paralysis, collapse, coma, a violent fall of the temperature and death. It is a narcotic, and in toxic doses causes nausea, vomiting, faintness, pain in the joints, numbness of the limbs, dryness of the mouth, convulsive movements, a small hard pulse, paralysis of the tongue, a purplish color of the face and hands, twitching of the eyelids and lips, trembling of the limbs, erythematous eruption, suppression of venereal desire, though recov.
