title: Effects of phenobarbitone and short-term exposure to heat on microsomal cytochrome P-450 and associated monooxygenases in rat liver.
abstract: Short-term exposure of the control and phenobarbitone-treated rats to high ambient temperature caused a different response of the hepatic microsomal cytochrome P-450-dependent monooxygenase system participating in the oxidation of aniline, aminopyrine and p-nitroanisole. The highest differences of the enzyme activities were observed in rats exposed to 28 degrees C, as compared with animals exposed to 21 degrees C or 37 degrees C.
