Concentration of reduced (a) and oxidized (b) glutathione in testis homogenate from rats exposed to gossypol and the protective action of vitamin E. The results represent the mean ± SEM of six animals per group. G1 = control; G2 = vitamin E 100 mg/kg BW; G3 = gossypol 5 mg/kg BW; G4 = gossypol 5 mg/kg BW + vitamin E 100 mg/kg BW. *^,**Significantly different from control (G1) (P < 0.05 and P < 0.01, respectively).
