As2O3预处理对离体缺血再灌注心肌的保护作用及机制
Protective effect of As2O3 preconditioning on isolated hearts with ischemia-reperfusion injury and its mechanism
摘要
Abstract
Objective To investigate the mechanism of the inhibiting effect of As2O3 preconditioning on heat shock protein (HSP)27 during ischemia/reperfusion injury (IRI) in isolated rat hearts. Methods Sixteen rats with IRI were divided into observed group and control group with 8 in each, the observed group was given As2O3 preconditioning by intrap-eritoneal injection, and the control group was given normal saline. The ventricular function, infaret size, ultrastructure changes and the expression of HSP27 were measured. Results Compared with control group, the LVEDP, LV +dP/dtmax and LV-dP/dlmax improved significantly, the ultrastructure injury lightened, while the expression of HSP27 increased obviously (all P<0.01). Conclusion As2O3 preconditioning can protect hearts with ischemia-reperfusion injury, the mechanism maybe related to increase the expression of HSP27.关键词
