Effect of carvedilol on testicular (a) reduced glutathione (GSH) and (b) malondialdehyde (MDA) in streptozotocin (STZ)-induced diabetic rat. Carvedilol was given in low dose of 1 mg/kg/day (Carv1) and high dose of 10 mg/kg/day (Carv10) as a single daily oral dose for 4 weeks. Values are represented as means ± standard error of the mean of 8 observations. Significant difference is reported when P < 0.05. ^aSignificant difference compared to control, ^bsignificant difference compared with STZ-induced diabetic group, ^cno significant difference compared to control
