title: [Comparative analysis of the antioxidant system of mouse liver and blood during exposure to toxins, extracted from drinking water].
abstract: A comparative analysis of the antioxidant system of mouse liver and blood was done during one month after a single per os administration of oil solutions of hexane--ether extracts from the drinking water sources with different proportions of benz(o)pyrene and polychlorbiphenyls. The absence of a linear dependence dose-effect on the extract concentration and a change in the scale and direction of interrelations between the parameters examined (the antioxidant activity of lipids, the content of peroxides, and the content of products interacting with 2-thiobarbituric acid) were revealed, indicating a high sensitivity and the absence of normalization of the antioxidant status in animal tissues.
