Topics in Toxicology Toxicology is a technological know-how that stands on the intersection of numerous pursuits and disciplines. those intersecting forces are certainly not all medical because a few are felony and a few are advertisement. All have legitimate issues to claim in regards to the behavior and interpretation of toxicity experiments. The working towards toxicologist needs to endure these kind of occasionally conflicting forces in brain as he includes out his tasks. this is often very true, after all, of the toxicologist in undefined. Toxicology is usually a box within which agreement learn relatively prospers and a couple of significant agreement study businesses have demonstrated through the years a name for contributing usefully to the perform of this ability. those agreement study agencies are particu­ larly favoured to strengthen an appreciation of the issues of the in­ dustrial toxicologist, because it is quite common for the sort of corporation to carrier the toxicological wishes of businesses in different sectors of generating new chemicals, and the agreement learn corporation, hence, knows a much wider diversiy of difficulties than most likely impacts a unmarried toxicologist in a single industry.

Animal accommodation It is necessary to house different species separately and to maintain high standards of animal husbandry throughout the studies. In chronic and carcinogenic studies we allow very limited access to animal rooms housing these studies. 3. Recruitment, training, environment The next basic requirements are the recruitment and the trammg of staff in the disciplines involved in toxicity evaluation. This requires the creation of the right environment for innovative scientific work.

The toxicologist therefore added a new group of control beagles to his study which he fed on golf balls. K. VIEW 25 accidentally or even that the brand and quality of the golf balls fed to the control group was uniform throughout the study. The fact that the control group dosed on golf balls showed no untoward effect does not preclude the interpretation that the toxicity seen in the top dose can have been due to an interaction between the drug and the golf balls. The same level of ignorance of drug quality is frequently demonstrated (i) in the context of toxicity tests which are conducted on material on which there is no batch analysis or specification of impurity pattern available (ii) toxicity tests conducted on two or more batches of material with greatly different specifications being used in the study and given to different dose level groups simultaneously or administered sequentially.

G. the developing fetus, and also includes the long term effects of the chemical in terms of carcinogenesis and mutagenesis. In its broadest sense the toxicological evaluation of an agent covers single dose LDso, short and long term toxicity studies, carcinogenicity studies and teratological and fertility studies. g. Ballantyne, 1977). Therefore it is unnecessary to reiterate them here and it is intended to consider only some of those factors that affect the quality or integrity of toxicity studies.
