本实验采用大白鼠离体心脏，在改良的Ｌａｎｇｅｎｄｏｒｆｆ模型上，研究甘利欣对心脏缺血再灌注损伤的保护作用及其作用机制。材料和方法选用１８０～２２０ｇ健康雄性ＳＤ大白鼠２１只，随机分３组，每组７只。对照组（Ｃ组）：用Ｋ－Ｈ液持续灌注７５分钟。缺血再灌注组（
In this study, isolated rat heart was used to study the protective effect of Glycyrrhizin on cardiac ischemia-reperfusion injury in a modified Langendorff model and its mechanism. MATERIALS AND METHODS: Twenty-one healthy male SD rats (180-220g) were randomly divided into three groups of 7 rats. Control group (group C): Continuous perfusion with K-H solution for 75 minutes. Ischemia reperfusion group (
