Figure 3: Effect of carvedilol on caspase 3 expression in testis of streptozotocin (STZ)-induced diabetic rats. Upper panel shows western blot expression of caspase 3 in testes of STZ-treated rats, with or without carvedilol 1 (Carv1) and 10 (Carv10) mg/kg/day orally for 4 weeks. Lower panel shows densitometric relative caspase 3 expression. Results are represented as percent of average of 3 different analyses compared with the control. Significant difference is reported when P < 0.05. aSignificant difference compared to control, bsignificant difference compared to STZ-induced diabetic group, cno significant difference compared with control
