Abstract:
Objective To assess the effect of intraarterial washout with UW solution and tanshinone Ⅱ A for skeletal muscle preservation during ischemia and reperfusion.Methods Ischemic rat limbs were perfused with UW solution or UW solution plus tanshinone Ⅱ A (0.05,0.1 and 0.2 mg/ml) for 0.5 h before reperfusion; controls received no perfusion.Serum CPK,LDH,and AST were measured pre-ischemia and after reperfusion (2 h,4 h,and 6 h).Muscle water content,MDA,SOD,ATPase were assessed pre-reperfusion and after 6 h reperfusion.ICAM-1 was detected after 6 h reperfusion.Results Intraarterial washout with UW and UW + T could inhibit the express of ICAM-1 in skeletal muscle.The serum levels of CPK,AST,and LDH in UW group were significant lower than those in control group after 2 h of reperfusion,but no difference was observed between UW group and control group after 4 h and 6 h of reperfusion.After 4 h of ischemia,there were significant differences in water content,MDA,SOD,and ATPase in skeletal muscle between UW group and control group,but no difference was found after 6 h of reperfusion.In contrast,all parameters of laboratory test and biochemical analyzing in UW + T(0.05,0.10,and 0.20 mg/ml) groups were significantly different from those in control group at corresponding reperfusion period.Conclusion Intraarterial washout with UW solution is effective in preserving skeletal muscle integrity against I/R insult.Tanshinone Ⅱ A as a beneficial adjunct to UW solution improves the protective effect of UW solution for ischemic skeletal muscle.To better preserve ischemic skeletal muscle,an appropriate dose of tanshinone Ⅱ A (0.1 or 0.2 mg/ml)added to UW solution is required.
