The techniques involved in the evaluation of the avian hemogram are easily performed by in-house veterinary laboratory person- nel. Because avian blood does not store well (eg, during transport), hematologic results obtained soon after collection are preferred over those performed 9 several hours later. In gen- eral, birds are better able to tolerate severe blood loss than mammals, which is due to their greater capacity for extravascular fluid mobilization. In healthy Mallard Ducks and racing pi- geons, a blood volume equivalent of up to three per- cent of the body weight can be collected. In Passeri- formes, pheasants and Psittaciformes, up to one percent of the body weight can be collected with few ill effects (0. The choice of a blood collection site is influ- enced by the species of bird, preference of the collec- tor, physical condition of the patient and volume of blood needed. Blood collected from capillaries (eg, blood from clipped nails) often results in abnormal cell distributions and contains cellular artifacts such as macrophages and material not normally found in peripheral blood (Figure 9. Other anticoagulants, such as heparin, interfere with cell staining and create excessive cell clumping, re- sulting in erroneous cell counts and evaluations (Color 9. The right jugular vein is usually chosen over the left for blood collection because in many birds it is the larger of the two. To collect blood from the jugular vein, the bird is properly restrained with the head and neck extended (Figure 9.

Acute toxicity test of both aqueous and ethanolic (95%) extracts of Triphala on albino mice have been conducted purchase 200mg cefixime with amex antibiotic rash. The antioxidant activity in ethanolic (95%) extract is higher than that of aqueous extract from Triphala order cefixime 100mg with amex antibiotic resistance graph. Their activities were compared against standard ascrobic acid and the antioxidant activity of gallic acid isolated from Triphala discount cefixime 200 mg with mastercard virus yole. From these results, the antioxidant activity of gallic acid was found to be higher than that of ascorbic acid. Study on the anti-diabetic activity and chemical constituents of Tinospora cordifolia Miers. Two medicinal plants, namely Tinospora cordifolia (Sindon-ma-nwe) and Wedelia calendulaceae (Negya-gale), which are used in traditional medicine for the treatment of diabetes, have been selected for chemical and pharmacological investigations. The two diterpene glycosides that have been isolated may be reported as the new finding in Tinospora cordifolia (Sindon-ma-nwe). Study on the antihypertensive activity and chemical constituents of Millingtonia hortensis Linn. The effect of watery extract of the whole plant on blood glucose level was tested on adrenaline-induced hyperglycaemic rabbit models. Oral administration of aqueous extract significantly reduced the blood glucose levels in the tested models within 1, 2, 3 and 4 hour. The plant extract reduced both systolic and diastolic blood pressure and the hypotensive activity was significant at the dosage levels of mg/kg at 10, 20, 30 and 40. The effect of alcoholic plant extract on urine formation was investigated in rats and was found to exhibit significant diuretic effect at 3, 4 and 5hr. The chemical that could affect the health of man was not recorded in the data obtained from phytochemical analysis. A study on the hypotensive action of leaves and root bark of Millingtonia hortensis Linn. The hypotensive action of aqueous extract of leaves and that of root bark of Millingtonia hortensis Linn. The hypotensive effect of extracts was studied on adult normal anaesthetized dogs of either sex. The blood pressure of the dog was recorded on smoked drum of Kymograph and measurements were obtained from mercury manometer. Both of the extracts suppressed the myocardial contraction in isolated rabbit heart. The extracts were also found to have diuretic action with a significant potassium loss in urine. Phytochemical analysis showed that both extracts have glycosides, saponins, tanninoids, carbohydrates and steroids. Most of the people living in various parts of Myanmar, especially in Shan State, use Cydonia cathayensis Hemsl. However, it has never been subjected to scientifically controlled trial in human volunteers. Thus, a randomized two way cross over study was conducted on twenty apparently healthy subjects of both sexes and ages between 25-55 years. Subjects were randomly divided into two groups and allopurinol 100mg three times a day (standard hypouricaemic drug) was administered to the first group for 14 days. It was followed successively by the washout period of 7 days and csOfapmfum;oD; (5gm of dried fruits was mixed with 150ml of water, over night and watery mixture (excluding dry fruits) was administered daily for 14 days. For the second group, csOfapmfum;oD; was administered in the first 14 days and after a washout period of 7 days, it was followed by allopurinol for 14days. Blood samples were collected on Day0, Day14, Day21 and Day 35 to determine the serum uric acid level before and after administration of drugs. Serum uric acid level of first group before and after administration of allopurinol was 4. Serum uric acid level of first group before and after administration of csOfapmfum;oD; was 4. Thus it seems that csOfapmfum;oD; had no hypouricaemic action and the mechanism of action for relief of aches and pains may be due to other actions of csOfapmfum;oD;. Study on the larvicidal activity and chemical constituents of Calotropis procera R. The main aim of this work is to develop environmentally safe, biodegradable, low cost, indigenous methods for vector control, which can be used with minimum care by individual and communicaties in specific situations. However, the larvicidal activities of this compound were much lower than that of synthetic larvicide (Deltamethrin). C and D could be considered as natural larvicidal agent and used as alternatives for conventional control that is environmentally safe and biodegradable. Water extract of Tagetes errecta show on lethality of the mice up to 7 days with a maximum giving dose level of 7g/kg indicating it has no harmful effects and hoped to be safety used as larvicide. Study on the organic chemical constituents & antibacterial activity of Azadirachta indica A. This thesis described about the investigation of phytoconstituents from two selected Myanmar medicinal plants and their pharmacological effects. Rotundine isolated from Taung-kya was also determined its analgesic activity in vivo compared with that of standard morphine by using tail clip method. Analgesic effect was measured by determining tail-pinch pressure needed to elicit a withdrawal response. As a result, the time onset of pain response of post treatment with rotundine was significant delayed (p<0. Comparative effect of pain response on pre and post treatment showed significant delayed the onset of pain response (p<0. Study on the potential use of preparation of Artemisia annua plants and its extracts on malaria infections. The global problem of multi-drug resistance in falciparum malaria is serious and prompt effective treatment of critically ill patients is mandatory. Nowadays, Qinghaosu, the active antimalarial principle of the Chinese herb Qinghao (Artemisia annua L.

Chagas disease [9] The diagnosis of chronic Chagas disease is virtually dependent on serology cefixime 100mg on line antibiotic associated diarrhea. Previously discount 100 mg cefixime with mastercard bacteria zapper for face, complement fixation was used widely but its technical difficulties and lower sensitivity make the new tests more popular purchase cefixime 200mg amex antibiotic vs antiseptic vs disinfectant. Cross-reactions can occur with sera from people with visceral or muco-cutaneous leishmaniasis, so clinical information is also necessary where these diseases could be a problem. Current work in progress suggests that monoclonal antibodies may be capable of discriminating even between different types of T. This could lead to a much greater understanding of the geographical pathology of the disease. African trypanosomiasis [11] The main purpose of serology in this disease is to detect parasitological inapparent cases and to monitor the efficacy of treatment. Gross elevation of serum IgM has been used as a screening test but of course there are numerous false positives and some infections are actually overlooked. Leishmaniasis [12] Visceral leishmaniasis is characterized by the production of excessive amounts of IgG and high levels of specific antibody. Serology can be of use in screening for the presence of the disease and for assessment of chemotherapy. Specific antibody levels are claimed to decrease rapidly after effective therapy but this is less well documented. Serology is of less value in cutaneous leishmaniasis but it can be useful in differentiating the muco-cutaneous disease from blastomycoses. Amoebiasis [13] The chief applications of serology are for the detection of invasive amoebiasis and the differential diagnosis of hepatic abscess and inflammatory bowel disease. However, problems can occur in highly endemic areas since 10% or more of the population without disease can have residual antibody from past infection. Schistosomiasis [15] In this disease the requirements are for tests which can be used for sero- epidemiological work and for individual diagnostic purposes. In addition, it would be valuable if serology could be used to monitor the efficacy of treatment. However, low sensitivity and problems relating to anticomplementary factors in many sera have restricted its use. When these tests were used with crude antigens similar problems of cross-reactivity were encountered. However, the purification of antigens has led to a marked improve­ ment in specificity. Nematode diseases [16] There is a real need for good specific serological tests for onchocerciasis and filariasis. The chief problems are due to crossreactions, since these nematodes share many antigens. Hydatid diseases [17] The immuno-diagnosis of echinococcosis is especially difficult because some patients have no detectable antibody or very low levels, even at present. Thus, the hydatid serology is especially difficult in areas where these other diseases are endemic. However, their high sensitivity is of little extra value because of the specificity problems. Progress has been made in this respect but as yet the problem is not completely solved. There is now a consensus of opinion that the labelled reagent methods used are satisfactory but the antigens employed are often not acceptable. It should be a matter of high priority to ensure that more specific antigens become available. Voller stated that the reasons for the emphasis on Ab detection were mainly historical; the trend was in favour of Ag detection. It might be possible to distinguish subjects with latent disease from those presenting more acute health hazards in terms of Ab or Ag levels. Isolation of organisms by culture is usually time-consuming and often unrewarding. Serological tests for antibody detection in serum for diagnostic purposes have not been useful since antibody levels persist long after the disease has subsided. The assay sensitivity was 1X 103 organisms/mL, or an equivalent of 1 ng/mL of sonicate antigen. There was very little (5%) cross-reactivity against other mycobacterial species except for Mycobact. Sixty-two samples were negative on smear and culture examination for tubercle bacilli. While 20 sputum samples were negative on smear they later turned out to be positive on culture. Abdominal cases were divided into definitely proven tuberculosis, either by laparoscopy and visualization of peritoneal tubercles, or culture positivity of samples. This very poor yield of 1%positivity despite a sensitive detection method was puzzling. It has been shown to be useful as a diagnostic test in the evaluation of pulmonary, pleural, ascitic and meningeal tuberculosis. The method is sensitive and specific and has the advantage that relatively crude antigen preparations at low concentrations can be used. Data revealed that the effect was caused in part from non-specific adherence of antibody to the solid phase during the first incubation and its subsequent elution from the solid phase and its reactivity in solution with most of the antigen during the second incubation. This problem was minimized by (a) using a high dilution of the test specimen, and (b) including animal serum and detergent in the specimen diluent. Reactivities were detected within three days after onset and were strong until about two months later when they began to decrease rapidly. Strong reactivity was detected for up to five months followed by a decline in reactivity. There was no significant difference in reactivity between specimens from patients who developed chronic hepatitis and those whose illness resolved uneventfully.

Instead of getting the story from a patient cefixime 100 mg cheap infection questions, you are getting it from your examiner discount 100mg cefixime fast delivery virus yardville. Your challenge is to get the details of that story from the examiner in a smooth and rational manner buy cefixime 200mg free shipping infection quality control. The subsequent text contains practical tips for the day as well as one approach to the oral board encounter. The last thing you want to do is get to the hotel late the night before because of a delayed fight. Nothing too heavy to eat the night before make sure you eat and go to sleep at a reasonable time. Eat breakfast the following morning but, don’t stuff yourself so that you’re uncomfortable during the exam. If you think you might get hungry, put a snack (like a granola bar) in your coat pocket just in case. Once you are called into the room for your encounter by the examiner, introduce yourself and greet them with a smile and handshake if 22 Emergency Medicine Oral Board review illustrated appropriate. Though these exams are standardized, it never hurts to be pleasant to the examiner. They are not supposed to give you any hints on how you did; just because you don’t hear “great job” or see a smile on their face doesn’t mean you didn’t do well. It is likely that you have done some mock oral boards exams during your residency and have learned a format that works for you. Because we work in a chaotic environment with multiple patients and typically high volumes, we rely on pattern matching and heuristics. Unfortunately, the oral boards are an artifcial environment and we lose the edge that we’ve come to rely on, our senses. The smell of melena, cyanotic lips, the use of accessory muscles to breathe, and subtle hints of delirium in an older patient must be revealed through asking questions instead of automati- cally presenting themselves to the candidate. So the candidate theoretically starts at a slight disadvantage in the encounter compared to the true clinical environment. Fortunately there is one aspect of the oral boards that we can use to our advantage: the examiner cannot lie and they are not there to trick you. This means if you ask them about breath sounds on the left side of the chest, they have to say “yes” or “no. To overcome the situational disadvantage of the artifcial physician–patient encounter, we have to maximize our data collection in an effcient way. However, if done correctly and practiced it will likely save you time in the long run. Use that time and divide the paper into four quadrants, labeled as illustrated in Figure 3. Memorize and write down all of the abbreviations before beginning so that you won’t forget to ask about certain aspects of the examination. You might not end up asking for all of them (like a rectal examination in a patient with an ankle sprain). For example, you may encounter a patient with left-sided sharp chest pain for 3 days, which is constant and not made worse with breathing. Unless you ask about the skin examination, you may miss the vesicular lesions along a dermatomal distribution seen in zoster. Be vague initially; if a portion of the examination is normal, the examiner will just say “normal” and you can move on. If it is especially relevant to the case or there are abnormalities to be discovered, they may ask you, “What are you look- ing for? In a multitrauma patient, it may be helpful to circle areas affected, such as the right femur, head, left chest. Other uses include marking the procedures you’ve done, such as the rectal examination, nasogastric tube, intubation, chest tube. If the patient is critical you will need to act immediately to stabilize the patient. Vitals are extremely important and will tell you a lot about the status of the patient. Continue throughout the case to frequently repeat vitals signs especially after an intervention, such as medications, administration, or procedure. Specifcally, place two large bore (16- to 18-gauge) angiocatheters in the anticubital fossa, start oxygen either by nasal canula or nonrebreather mask, and place the patient on a monitor. Not all patients may warrant these steps (the patient with an ankle sprain, for example) but the majority of sick patients will need these as a minimum. Ask them to stick around early in the case so you don’t lose them if you need to stabilize the patient frst. They can give you valuable informa- tion about mechanism of injury, pills at the bedside, or the condition of the patient’s home, as well as what treatments were given in the feld. Also, ask the patient how he or she is doing after each intervention (for example, asking, “How is the pain,” after giving morphine). You may have already sent basic laboratory work but you can add relevant data here. Avoid trying to shotgun lots of tests, as the examiner can deduct points if you are wasting resources. Mark down what you ordered because you may forget and the nurse does not have to voluntarily offer you the information once the results are available. You may be asked to describe how you would perform a pro- cedure, so be prepared (refer to Appendix G). Also, don’t forget social workers 26 Emergency Medicine Oral Board review illustrated or child protective services in abuse cases, calling primary care doctors to dis- cuss the patient, talking to family and the patient to update them on their status, explain all procedures, and appropriate disposition.
