Abstract: Maintainance of rats within 3 months on a ration with low content of vitamin E (6 mg/kg as compared with 100 mg/kg in control) did not alter distinctly the enzymatic activity in mitochondria, lysosomes and the activity of the enzymes, metabolizing xenobiotics as well as did not affect the permeability of lysosomal and plasmatic membranes. In subacute T-2 mycotoxicosis of rats kept on control ration the following alterations were noted: decrease in activity of lysosomal enzymes, aniline hydroxylase, carboxyl esterase and in content of cytochrome P-450 in liver tissue simultaneously with two-fold activation of epoxide hydrolase and UDP-glucuronosyl transferase; decrease in non-sedimented activity of lysosomal enzymes; decrease in activity of alkaline phosphatase and of lysosomal enzymes in blood serum. After administration of the toxin into vitamin E deficient rats, its effect was increased, hemorrhagic syndrome was distinctly developed, permeability of lysosomal and plasmatic membranes was increased. Subnormal consumption of vitamin E appears to cause destabilization of biological membranes structure, which is manifested under conditions of stress.
