RESUMO
Diclofenac (DIC) is a non-steroidal anti-inflammatory drug (NSAID) which is known to induce oxidative stress. Dithiocarbamates are compounds with proven antioxidant effect. The aim of the present study was to investigate the antioxidant capacity of diisopropyldithiocarbamates sodium salt (a synthetized compound) (Na(i-Pr2dtc)) against diclofenac-induced toxicity in the testes of male Wistar albino rats. The animals were assigned into six groups of six rats each. Group 1 (control) received corn oil, Groups 2, 3, 4, 5, 6 received DIC (100 mg/kg), DIC and (Na(i-Pr2dtc) (30 mg/kg), DIC and vitamin E (30 mg/kg), (Na(i-Pr2dtc) (30 mg/kg) and vitamin E only respectively. Our findings show that treatment with DIC significantly reduced superoxide dismutase (SOD) activity by 42% compared to normal control (NC) animals. In DIC treated group, Na(i-Pr2dtc) caused a 17% elevation of catalase (CAT) activity compared to DIC only group. Reduced glutathione level was significantly reduced in DIC only treated group when compared with DIC and VIT E treated group. Photomicrographs of testis from Na(i-Pr2dtc) treated rats showed normal seminiferous epithelium with no lesions. In conclusion, Na(i-Pr2dtc) has antioxidant properties.
