ObjectiveTo investigate the protective effect of Shenfu injection on liver injury in rats with hind limb ischemia-reperfusion and its mechanism. MethodsSixty-four male rats were randomly divided into sham operation group, ischemia-reperfusion group, Shenfu group〔Shenfu injection 7.5 mL/kg injection of peritoneal(ip), given 10 min before ischemia-reperfusion〕, Shenfu+Znpp group(Shenfu injection 7.5 mL/kg+Znpp 5 mg/kg ip, given 10 min before ischemia-reperfusion), 16 rats in each group. The rat model of hind limb ischemia-reperfusion injury was reproduced by occluding the hind limb artery of the rats for 3 h and subsequent reperfusing for 4 h. The liver tissues were gathered for malondialdehyde(MDA)and superoxide dismutase(SOD)determination. The expression of hemeoxygenase 1(HO-1)protein in the liver tissues was detected by immunohistochemistry. The pathological changes of liver were observed under the light microscope. The changes of serum glutamate-pyruvate transaminase(GPT)and glutamine oxaloacetic transaminase(GOT)were observed respectively. Results①Compared with the sham operation group, the contents of MDA, GPT, GOT, and the expression of HO-1 protein were markedly increased in the ischemia-reperfusion group, Shenfu group, and Shenfu+Znpp group(P < 0.05), the activities of SOD were markedly decreased in the ischemia-reperfusion group and Shenfu+Znpp group(P < 0.05).②Compared with the ischemia-reperfusion group, the contents of MDA, serum GPT, GOT, and the expression of HO-1 protein were markedly decreased, the activity of SOD was markedly increased in the Shenfu group(P < 0.05).③Compared with the Shenfu group, the contents of MDA, GPT, GOT were markedly increased, the activity of SOD was markedly decreased in the Shenfu+Znpp group(P < 0.05). Unde ther light microscope, the pathological changes induced by ischemia-reperfusion were significantly attenuated by the Shenfu injection in the Shenfu group and were reversed by the Znpp in the Shenfu+Znpp group. ConclusionShenfu injection inhibits liver tissue injury during hind limb ischemia-reperfusion, this protective effect might be partly through induction of HO-1.
ObjectiveTo discuss the protection effect of controlled reperfusion with Xuebijing injection on ischemia-reperfusion injury of rabbit hind limb, and provide a theoretical basis for prevention and treatment of limb ischemia reperfusion injury in clinical. MethodsThe big ear rabbit model of hind limb ischemia-reperfusion injury (ischemia 2 h, reperfusion 4 h) was made. Thirty healthy big ear rabbits were randomly divided into three groups: Xuebijing perfusion group (n=10): Xuebijing injection was given before reperfusion; Saline control group (n=10): surgical procedure with Xuebijing perfusion group, saline infusion was given before reperfusion; sham operation group (n=10): surgical procedure with Xuebijing perfusion group, ischemia and reperfusion was not performed. The activity of serum superoxide dismutase (SOD) and content of malondialdehyde (MDA) were detected. The ratio of blood flow (rBF) and ratio of blood volume (rBV) were tested. Results①Compared with the levels before operation, the activity of SOD and content of MDA had no significant differences after operation in the sham operation group (P > 0.05), the activity of SOD was obviously increased and the content of MDA was obviously decreased after reperfusion in the Xuebijing perfusion group (P < 0.01). Compared with the saline control group, the activity of SOD was obviously increased and the content of MDA was obviously decreased in the Xuebijing perfusion group.②Compared with the sham operation group, the rBF and rBV were obviously decreased in the Xuebijing perfusion group and the saline control group (P < 0.05); Compared with the saline control group, the rBF and rBV were obviously increased in the Xuebijing perfusion group (P < 0.05). ConclusionControlled reperfusion with Xuebijing injection could increase SOD activity in serum, reduce MDA content, it has a protective effect on hind limb ischemia-reperfusion injury in rabbits, and could effectively improve perfusion of hind limb.
