ABSTRACT
Objective To investigate the effect of calcium channel antagonist verapamil upon coronary vessel disease of allograft heart transplant rat model.Methods 160 SD rats weighing 220 to 300 g were randomly allocated to control group (group 1, n=40) and experiment groups (group 2, n=40; group 3, n=40, group 4, n=40). The hearts of all donor rats were implanted into the recipient rats. From the day after operation, the rats in each group were fed routinely and injected intraperitoneally (ip) with Cyclosporin (5 mg?kg~ -1?d~ -1 for 10 days). In experiment groups, the rats were individually injected (ip) with verapamil by 0.1 mg/kg,0.5 mg/kg,1.0 mg/kg twice every day for 3 months, but the rats in control group were not subjected to injection. At 60th and 90th day after grafting, 10 of each group were selected randomly and transplanted hearts were cut. The specimens were stained with HE and histochemistry.Result The degree of intimal hyperplasia in the control group was more severe than in the experiment groups.Conclusion Calcium channel antagonist verapamil can effectively inhibit the intimal hyperplasia of coronary arteries in heart transplant model.
