Abstract

To investigate the effects of T-2 toxin on the blastogenesis of lymphocytes, pathology, hemogram and blood chemistry in the goat, the korean native goats were treated orally with T-2 toxin for 21 days with a dosage of 0.6mg per kg body weight. The results were as follows: 1. The total count of leukocytes and lymphocytes decreased significantly from 14 to 21 days after treatment. 2. Mryeloid: erythroid ratios increased significantly on days 12 after treatment. 3. Delayed-type hypersensitivity skin reactions to tuberculin were reduced predominantly. 4. T-2 toxin induced prolonged prothrombin time. 5. Mitogenic responses of lymphocytes to both lipopolysaccharide and phytohemagglutinin were significantly depressed on days 7 and 14 after treatment. 6. Treatment of T-2 toxin caused marked depletion of lymphocytes in the thymus, mesenteric lymph node, peyer's patchs and spleen.
