Livers of mice previously treated with potential inducers were tested for effects on the microsomal cytochrome P-450-dependent monooxygenase system (including its constituent electron transport enzymes) and other enzymes. Microsomes were also examined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis.

Abstract The aim of the present study was to find a suitable wild-rodent to be used as terrestrial bioindicator. The wild mice were trapped at three sites around Vienna and at a fourth location in the countryside. Apodemus flavicollis , the yellow-necked mouse, was the most frequently captured mouse at all four sites.

DDT, in very first step of its detoxication is either transformed to DDD by reductive dechlorination (Walker i969; Hassal 1973) or DDE by dehydrochlorination (Datta 1970). For further detoxication, these metabolites undergo a series of reactions which result in the elimination of DDA in urine (Peterson and Robison 1964; Datta 1970; Gold and Brunk 1982).

Initial reaction rates of oxygen consumption and hydrogen peroxide formation in a cytochrome P-450 catalyzed reaction are practically independent of the nature of tertiary amines that were used as substrates. From the kinetic studies and the substrate conversion results that the amount of water formed in a side reaction is determined by the substrate ...

In the presence of a spin trapping reagent, N-tert-butyl-alpha-phenylnitrone, anaerobic incubation of halothane (2-bromo-2-chloro-1,1,1-trifluoroethane) with a reconstituted cytochrome P-450 enzyme system of rabbit liver microsomes exhibited an electron spin resonance spectrum containing signals of a nitroxide radical, and all components of the ...

The effect of acute hemorrhage on the functional status of microsomal cytochrome P-450-dependent hepatic monoxygenases and the impact of induction of these monoxygenases on the survival of posthemorrhagic male Wistar rats. Acute blood loss of the rats, which caused 50% deaths led approximately to a double decrease in the hepatic activity of 77 ...
