Abstract
The objective of this study is to assess the potential protective effect of Tadalafil on myocardial ischemia reperfusion injury induced by LAD ligation, 28 male rats were randomized into 4 groups (7 rats per group); Sham, rats underwent the same anesthetic and surgical procedure except for LAD ligation; control, rats underwent LAD ligation for 30 minutes and reperfusion for 2 hours; vehicle, rats treated with 10% DMSO, the Tadalafil solvent 30 minutes before the ligation; Tadalafil group, rats pretreated with Tadalafil1mg/kg i.p 30 minutes before ligation. In control group, as compared with sham, tissue TNF-α, IL-6, IL-10, caspase-3 and BAX, plasma cTn-T and serum MDA significantly increased (P<0.05), while serum GSH significantly decreased (P<0.05). Histopathologically, control group showed a significant cardiac injury (P<0.05) compared with sham group. Tadalafil significantly counteracted (P<0.05) the increase of TNF-α, IL-6, caspase-3 and BAX and counteracted the increase in plasma cTn-T and serum MDA. Tadalafil produces a significant elevation (P<0.05) in cardiac IL-10 and serum GSH with significant reduction in (P<0.05) cardiac injury. In We concluded that Tadalafil attenuates myocardial I/R injury in male rats through interfering with inflammatory reactions and apoptosis .
