The fate of foreign compounds in man and animals.

چکیده
INTRODUCTION There occur in our environment today a large number of compounds which are normally regarded as foreign to the body. Many of these get into the body in various ways and therefore it is important to know how they affect our health and how the body deals with them. These chemicals may appear in the body because they have been deliberately put there as in the case of drugs, deliberate food additives and contraceptive pills, or because they have entered the body accidentally as contaminants of food, drink and air. These contaminants may be pesticide residues, industrial chemicals in factories, products from the preparation and packaging of food, and foreign substances which occur naturally in food but have no nutrient function. The animal body has therefore to deal constantly with small quantities of thousands of compounds of very diverse chemical structures (see Table 1). Many of these chemicals are toxic and man is therefore living in a toxic environment. In view of the increasing use of drugs, pesticides and food additives, there is little doubt that we are existing in an increasingly toxic environment. Even before the modem era of drugs, food additives and pesticides, the human body had to cope with a large number of toxic substances which occur naturally in food'. The fact that our environment is becoming increasingly toxic raises the problem of what is the limit

Animals dosed orally with nitrite (1.5 X 10(-3) mol/kg) and nonyl dimethylbenzylammonium bromide (2.9 X 10(-4) mol/kg) exhibit liver damage within two hours; cetyl trimethylammonium bromide plus nitrite was not significantly hepatotoxic. Both nonyl dimethylbenzyl ammonium bromide and cetyl trimethylammonium bromide were demethylated by rat-liver microsomal preparations; substrate concentrations...

متن کاملSpecies variations in the pathways of drug metabolism.
The basic pattern of the metabolism of foreign compounds is the same in all species, in that most foreign compounds are metabolized in two phases, in the first of which the compound may be oxidized, reduced, or hydrolyzed and in the second the products of the first phase may undergo a synthesis or conjugation to form polar excretory products. Within this pattern, however, tremendous variations ...
