Abstract
In an attempt to clarify the protective action of an antioxidant agent against acute toxicity of thioacetamide (TAA) and in order to throw some light on an satisfying concept of the mechanism of its action, a single dose of alphatocopherol (200 mg per kg) was given orally by stomch tube to male mice prior to the administration of thioacetamide in a dose of 200 mg per kg of body weight. Sections of liver samples, obtained from the mice which were sacrificed at intervals of 3, 6, 9, or 12 hours after TAA administration, were stained using the methyl green-pyronin technique.
At 3 hours following TAA administration, the pretreatment with alpha-tocopherol inhibited almost completely such alterations of the hepatocytes in the animals given TAA alone, as revealed by loss and clumping of cytoplasmic pyroninophilic granules in the periportal zone of the lobule.
At 6, 9, and l2 hours, the prevention of alpha-tocopherol was incomplete in degree and extent. The changes of the hepatocytes were more intense and extensive in the TAA-treated 6 to 12 hour-groups than in the 3 hour-group of TAA-treated ones.
Some discussion is given of the mechanism of TAA toxicity, with respect to the microsoma1 lipid peroxidation.
