山鸡椒又名山苍子,治疗冠心病有较好的疗效。本文用结扎家兔冠状动脉左室支,造成急性心肌梗塞模型以及从左心室插管,分别观察山鸡椒油对心肌梗塞范围和对血液动力学的影响。 一、抗急性实验性心肌缺血的作用:结扎左室支24小时后再次开胸取出心脏,经N—BT液染色算出心梗范围。家兔23只,分三组:对照组12只、术前、后1和6小时各静注生理盐水0.5ml/kg;心得安组5只、
Shan Jijiao, also known as Litsea cubeba, has a good effect in the treatment of coronary heart disease. In this paper, the left ventricular branch of coronary arteries was ligated to cause acute myocardial infarction model and intubation from the left ventricle to observe the effect of shanzhi pepper oil on myocardial infarction range and hemodynamics. First, the role of anti-acute experimental myocardial ischemia: left ventricular branch ligation 24 hours later re-open the chest to remove the heart, the N-BT fluid staining to calculate the scope of myocardial infarction. Twenty-three rabbits were divided into three groups: 12 in the control group, 0.5 ml/kg of physiological saline before and 1 and 6 hours after the operation, and 5 rats in the propranolol group.
