4.2.11.5 Effect of co-administration of TCDD and vitamin E on the antioxidants in the caput. corpus and cauda epididyrnideo Co-administration of TCDD and vitamin E did not show any significant change in the levels of reduced glutathione and a-tocopherol in all regions of the epididymis of adult rats with respect to the corresponding groups of control animals (Table 32). 4.2.1 1.6 Effect of co-administration of TCDD and vitamin E on the antioxidant enzymes and lipid peroxidation in the caput, corpus and cauda epididymides The activities of superoxide dismutase, catalase, glutathione reductase and glutathione peroxidase as well as the levels of lipid peroxidation did not alter significantly in the caput, corpus and cauda regions of the epididymis of rats treated with TCDD and vitamin E when compared to the corresponding group of control animals (Table 33a; 33b & 33c). 4.2.12 Effect of co-administration of TCDD and vitamin E on the levels of reactive oxygen species production, antioxidants, antioxidant enzymes and lipid peroxidation in Kidney Co-administration of TCDD and vitamin E did not show any significant change in the production of superoxide anion, nitric oxide and hydrogen peroxide in the kidney of adult rats as compared to the corresponding groups of control animals (Table 34a). Administration of TCDD along with vitamin E did not cause any significant changc in the levcls of roduccd gluti~thic)nc and cr-Iocoplicrol in Ihc Lidncy ofadult rats with respect to the corresponding groups of control animals (.!'able 34b). The activities of superoxide dismutase, catalase, glutathione reductase and glutathione peroxidase and the level of lipid peroxidation of the kidney did not show any significant change in the rats administered with TCDD and vitamin E as compared to the comsponding group of control animals (Table 34c).
