摘　　要：目的:探讨中药益生注射液对大鼠离体心脏冷缺血损伤的保护作用,为临床应用提供部分实验依据。方法:采用雌性封闭群SD大鼠18只,分两组,对照组的离体心脏用4℃生理盐水保存,实验组的离体心脏则用含益生注射液的4℃生理盐水保存,分别于冷藏2、6、12、24、48和72h取材作酶组织化学检查。结果:对照组,冷藏24h,碱性磷酸酶(ALP)、辅酶Ⅱ黄递酶 (NADPHD)活性开始下降;冷藏48h后,乳酸脱氢酶(LDH)活性开始下降,ALP和NADPHD活性明显下降;冷藏72h后,琥珀酸脱氢酶(SDH)和细胞色素氧化酶(CCO)活性开始下降,NADPHD活性几乎完全丧失;实验组,冷藏24h、48h和72h,NAD- PHD、LDH和CCO活性分别开始下降,但不如对照组明显;冷藏48h后,ALP活性才开始下降;冷藏72h,SDH活性无变化。结论:冷缺血可引起离体心肌损伤,其中血管内皮细胞对冷缺血损伤最敏感,益生注射液对离体心肌冷缺血损伤具有保护作用。Objective：To investigate whether the traditional Chinese medicine Yisheng Injection can reduce the injury on isolated rat heart induced by cold isehemia. Methods ：18 isolated female closed colony SD rats were divided into two groups at random. In the control group, the isolated rat hearts were preserved in 0.9% sodium chlorine solution at 4℃, while in the experimental group ,the hearts were preserved in 0.9% sodium chlorine solution containing Yisheng injection at 4℃. The specimens were harvested 2,6,12, 24,48 and 72 hours after preservation. Histochemical changes were observed in two groups. Results ：In the control group, the activities of alkaline phosphatase （ ALP） and NADPH diaphorase （ NADPHD） decreased after cold ischemia for 24 hours. Lactic dehydrogenase （LDH ） decreased slightly, while ALP and NADPHD decreased evidently, after cold ischemia for 48 hours. Succinic dehydrogenase （ SDH ） and cytochrome oxidase （ CCO ） decreased slightly, and NADPHD disappeared after cold ischemia for 72 hours respectively. In the experimental group, NADPHD, LDH and CCO decreased slightly after cold ischemia for 24, 48 and 72 hours. ALP decreased slightly after cold ischemia for 48 hours, however, SDH showed no changes, after cold ischemia for 72 hours. Conclusion ： Cold ischemia can induce cold ischemia injury in isolated rat hearts, especially the vascular endothelial cells being more sensitive. Yisheng injection can reduce this kind of injury to some degree.
