Establishment and use of Plasmodium berghei-mouse model in Burma for the screening of drugs for antimalarial activity. Plasmodium berghei infection produces a self resolving benign type of infection in albino rats. The level of parasitaemia was significantly increased in female rats than the male and also in the younger age group than the older one. The relationship of the infective inocula and the prepatent period was found to be linear with an approximate slope of r=0. The antimalarial effect was not elucidated with the extracts of Pan-daw-na, Taw-daw-na, Thu-young-kha, Khant-tauk-myint and Let-htoke-gyi. Kanamycin, Ampicillin, Isoniazid, Griseofulvin, Diethylcarbamazine and Furazolidone did not produce any antimalarial effect. The establishment of in vitro screening model for antimalarials using rabbit serum and Plasmodium falciparum. A rabbit in vitro model system is tested to determine the activity of antimalarial drugs against P. Serum samples obtained from rabbits at various time intervals after administration of drugs were incubated with parasites collected from patients. Antimalarial activity was detected in sera obtained from rabbits treated with amodiaquine, chloroquine, quinine and pyrimethamine. The rabbit in vitro system using quinine or chloroquine treated rabbit serum showed the definite relationship with the sensitivity pattern of in vitro testing using precharged plates with known amount of antimalarials and human serum. The model was also found to be useful for the screening of the extracts of Artemisia annua. The results indicated that this model may be a useful system for further screening of drugs against falciparum malaria, particularly compounds which need to be metabolised in vitro. Evaluation of antibacterial activity and characterization of phytoconstituents of selected Myanmar medicinal plants. Studies on the morphology of the vegetative and reproductive parts and the anatomy of the leaf blade, leaf sheath, bulb and roots have been made. Comparative physico-chemical and phyto-chemical studies on garlic collected from three different localities namely, Taunggyi, Mogoke and Monywa Townships were conducted. The main constituent of garlic, allicin, from the bulb was extracted and identified by the thin layer chromatographic and spectroscopic determinations. Evaluation of antidiarrhoeal activities of some isolated bioactive organic compounds present in Melastoma malabathricum Linn. The investigation was conducted by castor oil-induced diarrhoeal test, castor oil-induced entropooling test and castor oil-induced small intestinal transit test. From these results, it can be inferred that aqueous extracts from both plant samples and ethyl gallate had frequencies of diarrhoeal reducing effect, anti-secretary effect and anti-motility effect. From this experiment, it was observed that both aqueous extracts and ethyl gallate had direct relaxation effect on smooth muscle. The relaxation effects were increased with increasing the concentrations of all samples tested. It was also observed that both aqueous extracts and ethyl gallate showed marked decrease in magnitude and frequency of ileal contraction and decrease in intestinal movement. It indicated that both extracts and ethyl gallate have anti-muscarinic activity as atropine and tolazoline and they also have anti-histamine activity very similar to that of chlorpheniramine.

In order to combat the problems of diarrhoea globally, World Health Organization has given a special emphasis on the use of traditional medicines in management of diarrhoea. It thus becomes important to evaluate commonly available natural drugs as alternative to currently used anti-diarrhoeal drugs. The aim is to evaluate in vivo and in vitro antidiarrhoeal activity of reputed Mango seed kernel. In vivo the anti- diarrhoeal activity of aqueous extracts were carried out using castor oil-induced diarrhoea model in mice with the standard loperamide. Like loperamide, a single oral dose of its extract produced significant reduction in fecal out put and onset of diarrhoea (p<0.

If negative feedback is working properly prasugrel 10mg low price, a missile or a torpedo reacts to "criticism" just enough to correct course and keeps going forward toward the target prasugrel 10 mg on line. However order prasugrel 10 mg otc, if the mechanism is too sensitive to negative feedback, the servo-mechanism overcorrects. Instead of progressing toward the target, it will perform exaggerated lateral zig-zags, or stop all forward progress altogether. We must have negative feedback in order to operate purposely, in order to steer our way, or be guided to a goal. When we over-react to negative feedback of criticism, we are likely to conclude that not only is our present course slightly off-beam, or wrong, but that it is wrong for us even to want to go forward. When he is ready to return to his car, he looks for his tree (or target) and starts walking towards it. From time to time the tree may be lost from his view, but as soon as he is able he "checks course" by comparing his direction with the location of the tree. If he finds that his present course is taking him 15 degrees to the left of the tree, he must recognize that what he is doing is "wrong. When it comes to our attention that our manner of expression is off course, missing the mark, or "wrong"— we conclude that self-expression itself is wrong, or that success for us (reaching our particular tree) is wrong. Keep in mind that excessive negative feedback has the effect of interfering with, or stopping completely, the appropriate response. Stuttering as a Symptom of Inhibition Stuttering offers a good illustration of how excessive negative feedback brings on inhibition, and interferes with appropriate response. While most of us are not consciously aware of the fact, when we talk we receive negative feedback data through our ears by listening to or "monitoring" our own voice. They have no way of knowing whether their voice is coming out as a shriek, a scream, or an unintel- ligible mumble. This is also the reason that persons born deaf, do not learn to talk at all, except with special tutor- ing. Voice teachers advise that we record our own voices on a tape recorder, and listen back to them, as a method of improving tone, enunciation, etc. We are able to see clearly what it is we are doing "wrong"—and we can make correction. If we are consciously overcritical of our speech, or if we are too careful in trying to avoid errors in advance, rather than reacting spontaneously, stuttering is likely to result. When asked to read aloud from a prepared text under these conditions, which eliminated self-criticism, the improvement was "remarkable. When excessive negative feedback, or self-criticism, was eliminated, inhibition disappeared and performance improved. When there was no time for worry, or too much "carefulness" in advance, expression immediately improved. This gives us a valuable clue as to how we may disinhibit or release a locked up personality, and im- prove performance in other areas. Excessive "Carefulness" Leads to Inhibition and Anxiety Have you ever tried to thread a needle? If so, and if you are inexperienced at it, you may have noticed that you could hold the thread steady as a rock until you approached the eye of the needle and attempted to insert it into the very small opening. Each time you tried to place the thread through the small opening, your hand unaccountably shook and the thread missed the mark. Attempting to pour a liquid into the mouth of a very small-necked bottle often results in the same kind of be- havior. You can hold your hand perfectly steady, until you try to accomplish your purpose, then for some strange reason you quiver and shake. In certain pathological con- ditions, such as injury to certain areas of the brain, this "purpose tremor" can become very pronounced. But let him try to insert his door-key into the lock on his front door, and his hand may "zigzag" back and forth as much as six to ten inches. If he is ashamed of this, and becomes even more "careful" not to make an error in the presence of strangers, he may not be able to sign his name at all. These people can be helped, and often remarkably, by training in relaxation techniques where they learn to relax from excessive effort and "purposing" and not to be overly-careful in trying to avoid errors or "failures. As in the case of the stutterer, who attempts to anticipate pos- sible errors and be overly-careful not to make them—the result is inhibition and deterioration of performance. Both have to do with too much concern for possible failure, or do- ing the "wrong thing," and making too much of a con- scious effort to do right. How can conversation possibly steer itself through such a sea of responsibilities and inhibitions such as this?

The introduction of immunoassay to laboratories where environmental changes and limited equipment are likely to limit reliability and precision have emphasized the need for routine evaluation of assay performance. The aim has been to provide both an accurate calibration of the immunoassay response and an assessment of assay error which will allow the assayist to monitor and improve assay performance. As models of immunoassay error are used at all stages of processing they are described in some detail. Analysis of sources of error associated with counting, small perturbation “experimental” errors and assay “drift” is explicitly embraced by the program and is used to screen out untypical assay errors or “outliers”. This is a statistically more reliable estimate of precision than the observed replication for an individual result and when calculated for doses over the working range of the assay yields the precision profile as an important indicator of assay performance. These error sources all give rise to intra-batch changes and further analysis of the quality control samples is required to detect inter-batch variations. A considerable family of functions have been applied to model the immunoassay response and the reasons for selection of the logit and mass- action forms are discussed. A four-parameter single-binding-site model was chosen for the initial, program release. The problem of the assayist losing contact with the nature of the data being processed when insufficient (or excessive) statistical output is provided has been considered and graphical presentations have accordingly been introduced wherever possible. Pictorial representation is seen as a way of conveying large amounts of statistical information in an intelligible form while allowing the assayist to retain a “feel” for the underlying data. Apart from the immediate intra­ laboratory benefits of data processing it is expected that the processing of large amounts of immunoassay data in a standard format will provide a unique data base. This may be used to examine changes in processing techniques and to compare assay performance between laboratories in otherwise impractical detail. Most of these programs have provided a satisfactory calibration but included little analysis of assay error. The appearance of the cheap microcomputer has multiplied the number of potential users and created a need not merely for specific programs but a clear understanding of the concepts on which these programs should be based. The introduction of immunoassay into laboratories where environmental changes and limited equipment are likely to limit reliability and precision have further emphasized the need for programs which allow routine evaluation of assay performance. The constraints of the microcomputer and the need to accommodate a wider range of users necessitated considerable changes to the original program. The opportunity was therefore taken to revise the actual processing, simplify presentation, exploit the graphics facilities of this micro­ computer and to provide more complete documentation. The aim is to provide both an accurate, robust calibration of immunoassay response and an assessment of assay error which will enable the assayist to monitor and improve assay performance. As models of immunoassay error are used throughout processing they will be described in some detail. The second part of the paper describes the actual program, and goes on to discuss briefly some problems of software development on microcomputers. In a more realistic case e might be characterized by a Gaussian distribution which is defined by two parameters: (i) The expected value of e: E(e) - or the instrument bias. Immunoassay, however, is a rather unreliable multi-stage procedure with the possibility of different errors being introduced at each step. It then becomes useful for the assayist to be able to distinguish, and perhaps monitor, those sources of error thought to make a significant contribution to the overall assay performance. More complex effects may be modelled by the use of non-Gaussian distribu­ tions, by introducing models for other sources of error, or by allowing the existing model parameters to be dependent upon factors such as time or assay response. We may now describe any source of error and include it in an analysis of assay error if the model parameters (or statistics) are known or can be determined. When the parameter values are uncertain the assayist must undertake an experi­ ment to estimate them. An example of increased complexity arises from the desire to describe the observed dependence of assay precision upon the measured dose. The error observed among replicates can be considered the sum of counting and laboratory errors. This counting error can be further broken down into a “background” component and an error arising from the inherently random nature of radioactive decay. If these components are considered to be important they can be described as in Fig. If these factors are to be included and distinguished entirely from other noise then the assay protocol must allow their detection, perhaps by repeated counting of the same tubes. In practice the assayist is likely to rely upon occasional checks for counter stability.

There are receptors for testosterone on the cells of both hair follicles and the prostate discount 10mg prasugrel otc. These findings mean not that balding men will definitely get prostate cancer buy prasugrel 10 mg with mastercard, but only that they are at increased risk generic 10mg prasugrel amex, meaning that they would be wise to be more aggressive with dietary and supplementation programs to reduce their risk of developing prostate cancer. In fact, it would be worthwhile to read the chapter “Breast Cancer (Prevention)” to gain an even greater appreciation of how diet can affect hormone-sensitive tissues like the breast and prostate. One of the interesting dietary associations in breast cancer is the high risk that comes with eating well-done or charbroiled meat; frequent consumption of well-done meat, for example, was associated with a nearly 500% increase in breast cancer. Higher consumption of hamburgers, processed meats, grilled meats, and well-done meat was associated with an approximately 50 to 80% increase in aggressive forms of prostate cancer. In a study conducted in Canada, researchers found a twofold increased risk of prostate cancer associated with an increased intake of milk. Interestingly, it was the only dairy product associated with an increased risk for prostate cancer. It is also important to point out that the Mediterranean diet has been shown to help prevent prostate cancer. That would be expected given that it is high in vegetables, legumes, dried and fresh fruits, and fish; olive oil is its main fat source; it is low in animal fats, processed red meat, milk and dairy products; and it includes regular but low alcohol intake (wine with meals). The high intake of soy may be one of the key protective factors accounting for the low rate of prostate cancer in Japan and China compared with other parts of the world: blood and urine concentrations of soy isoflavones (an indicator of intake) were found to be 7 to 10 times higher in Japanese men consuming a traditional Japanese diet compared with Finnish men consuming a typical Western diet. Information on the isoflavone content of common soy foods can be found on page 788. Just as in breast cancer again, the benefits of these long-chain omega-3 fatty acids are magnified when the level of animal fat (saturated fat, and arachidonic acid in particular) is also reduced. A high ratio of dietary omega-6 to omega-3 fatty acids is major risk factor for prostate cancer. Unfortunately, no one has actually looked at the effect of flaxseed oil in prostate cancer. At this time it appears that men in general may be better off avoiding flaxseed oil supplements and focusing on ground flaxseed (for the lignans) and fish (for the omega-3 fatty acids). Flaxseed Ground flaxseed appears to be quite helpful not only in preventing prostate cancer but also in men with existing prostate cancer. In addition to its phytoestrogenic effect, flaxseed lignans also bind to male hormone receptors and promote the elimination of testosterone. In a study of men with prostate cancer, a low-fat diet (with fat providing 20% or less of total calories) supplemented with 30 g ground flaxseed (roughly 2 tbsp) reduced serum testosterone by 15%, slowed the growth rate of cancer cells, and increased the death rate of cancer cells after only 34 days. Although genetics could play a role, a more likely explanation is dietary differences. In a study conducted by the National Cancer Institute of men who had been newly diagnosed with biopsy-proved prostate cancer and matched controls without prostate cancer, it was shown that increased consumption of foods high in animal fat was linked to prostate cancer (independent of intake of other calories) among black men compared with whites. The higher the intake of animal fat, the greater the risk for advanced prostate cancer. These results indicate that diet plays a major role in why black men have a higher rate of prostate cancer and show that a reduction of fat from animal sources in the diet could lead to decreased incidence and mortality rates for prostate cancer, particularly among African- Americans. In one, a total of 29,133 male smokers ages 50 to 69 from southwestern Finland were randomly assigned to receive vitamin E (50 mg), beta-carotene (20 mg), both nutrients, or a placebo for 5 to 8 years (median 6. A 32% decrease in the incidence of prostate cancer was observed among the 14,564 subjects receiving vitamin E compared with the 14,569 not receiving it. However, in the 14,560 subjects receiving beta-carotene, prostate cancer incidence was actually 23% higher and mortality was 15% higher compared with the 14,573 not receiving it. Another form of vitamin E, known as gamma-tocopherol, may prove to be more important against prostate cancer than the alpha-tocopherol form, which has been used in virtually all the vitamin E research. Eight different compounds—four tocopherols and four tocotrienols—make up the vitamin E family. They have some functions that are similar and other functions that are completely different. Alpha-tocopherol became synonymous with vitamin E for two main reasons: (1) of the eight, it is the most abundant in the human body, and (2) it is by far the most effective of the eight for what was originally thought of as vitamin E’s main function—to support reproduction. Our blood and tissue contain much more alpha-tocopherol than gamma-tocopherol despite the fact that in the typical American diet we consume twice as much gamma-tocopherol as alpha. The reason is that the liver is able to identify the alpha-tocopherol as it is absorbed from the gut and bind it to a special protein, called the alpha-tocopherol transfer protein. It recognizes the alpha- tocopherol and preferentially puts more of it in lipoproteins—proteins that carry fat and cholesterol (e. This compound and other metabolites may act to better protect the prostate from oxidative damage as well as promote apoptosis (programmed cell death), which helps prevent cells from becoming cancerous. In one study, 117 men who developed prostate cancer and 233 matched control subjects had toenail and plasma samples assayed for selenium, alpha-tocopherol, and gamma-tocopherol. For gamma-tocopherol, men with the highest levels had a fivefold reduction in the risk of developing prostate cancer compared with men with the lowest levels.
