title: Biochemical changes in subacute mycotoxicosis induced by T-2 toxin in rats.
abstract: The intragastric administration to male Wistar rats of T-2 toxin at 1-1.3 mg/kg body weight for 7 days caused a sharp decrease in the liver activity of lysosomal enzymes: beta-galactosidase, beta-N-acetylglucosaminidase, alpha-mannosidase, cathepsins A, B, C and D and in the activity of enzymes of the 1st phase of metabolism of xenobiotics--aniline hydroxylase and carboxylesterase, as well as in the cytochrome P-450 level. At the same time, the subacute toxic effect of T-2 toxin was manifested in a significant increase in the activity of epoxide hydrolase and an enzyme of the 2nd phase of metabolism of xenobiotics--UDP-glucuronosyltransferase. A possible mechanism of the observed enzymological changes is discussed.
