Abstract:
Objective;To investigate whether the traditional Chinese medicine Yisheng Injection can reduce the injury on isolated rat heart induced by cold ischemia. 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 dehydro-genase (LDH) decreased slightly, while ALP and NADPHD decreased evidently, after cold ischemia for 48 hours. Succinic dehydro-genase ( 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.
