蒋传付氏等报道:用11只健康家兔作实验,从耳缘静脉给玉芪方(按生药计4克/公斤,P_Ⅱ调至7.0～8.0),分析统计每只家兔的对照期及实验期心电图变化。将实验期与对照期T波峰值及3分钟内T波均数进行显著性测验。结果发现实验期与对照期T波增加百分率比较P≤0.01,差异非常显著。实验证明,玉芪方有一定的抗心肌缺血作用,对脑垂体后叶素所致的急性心肌缺血有一定的保护作用。作者认为,这种保护作用,可能与松驰血管平滑肌、扩张冠脉及改善心肌
Chuan Chuanfu et al. reported that 11 healthy rabbits were used to test the rabbit’s control period and experiment from the marginal vein to the Yuzhufang (4 grams/kg based on crude drug, P_II adjusted to 7.0 to 8.0). ECG changes during the period. The T-wave peak values in the experimental period and the control period and the T-wave mean in 3 minutes were tested for significance. As a result, it was found that the percentage increase of T wave in the experimental period and the control period was P≤0.01, and the difference was very significant. Experiments have shown that Yuxifang has certain anti-ischemic effects on myocardium and has a protective effect on acute myocardial ischemia caused by pituitrin. The authors believe that this protective effect may be associated with relaxation of vascular smooth muscle, dilation of coronary arteries, and improvement of myocardium
