目的 :观察益心口服液对大鼠心肌缺血再灌注心肌细胞内钙离子的影响。方法 :( 1 )采用大鼠左冠状动脉前降支结扎、放松制造急性心肌缺血再灌注模型。动物分成正常组、假手术组、模型组、预处理组、益心口服液组、消心痛组 (各 1 0只 )。 ( 2 )心肌细胞内Ca2 +测定 :离体心脏?
Objective : To observe the effect of Yixin Oral Liquid on intracellular calcium of rat myocardial ischemia-reperfusion cardiomyocytes. METHODS: (1) The left anterior descending coronary artery was ligated and relaxed to create an acute myocardial ischemia-reperfusion model. Animals were divided into normal group, sham operation group, model group, pretreatment group, Yixin oral solution group, and isosorbide dinitrate group (n = 10 each). (2) Determination of intracellular Ca2 + in cardiomyocytes: isolated heart?
