观察健康人血清肌酸激酶同功酶ＭＢ与心室碎裂电位切迹数的关系，探讨诊断心肌局灶轻微损伤的方法。方法 选择２０－７１岁的健康人１３０例，用ＵＶ－２６０型紫外分光光度仪检测血清ＣＫ－ＭＢ，ＲＭ－８６型八道生理记录仪与ＳＣ－１６型紫外光线记录器匹配检测ＶＦＰ，并计算Ｎ．用Ｆ检验和相关回归方法进行统计学分析。     

人胚胎和新生儿心室肌心钠素发生的电镜免疫细胞化学研究

用包埋后电镜免疫细胞化学方法，研究了不同胎龄胚胎及新生儿心室股纤维中心钠素的胚胎发生，对心肌纤维内心钠素颗粒进行了体视学分析及统计学处理。结果表明：随着胎龄增长，细胞内肌丝由稀疏逐渐增多然后形成肌原纤维，线粒体的数目也逐渐增多；心钠素颗粒于第５周开始出现，颗粒的数目随胎龄增加而逐渐减少。至妊娠７月时基本消失。     

山羊急性心肌缺血时恶性心律不齐的发生和...

The coronary collateral circulation of goat is very spare, so myocardiac ischemia model of goat can simulate the patient previously with normal coronary circulation and suddenly developing complete occlusion of coronary arteries. In this study 80 Chengdu goats were used, and the branches of their left coronary artery were ligated. Ventricular tachycardia (VT) developed in 23 goats and ventricular fibrillation (VF) in 39 goats. VT and VF both occurred in the early phase of acute myocardial ischemia, and both had 6 min as the median time of onset. In 71 cases data on the weight of myocardiac ischemic area were collected, in which the weight percentage of ischemic area relating to the ventricles of 34 goats with VF was significantly higher than that of 37 goats without VF (35.4 +/- 2.4% vs 19.5 +/- 1.9%). After coronary ligation, 9 cases directly precipitated into VF which could not be defibrillated. In the remaining 62 cases, the weight percentage of ischemic area of 21 cases with VT was higher than that of 41 cases without VT (32.9 +/- 2.8% vs 20.9 +/- 2.1%). The relationships between the incidence of VT or VF and the weight percentage of ischemic area were fitted with logistic curve. The likelihood of occurrence of VT or VF is increased as the weight percentage of ischemia area goes up.     

信号平均心电图低振幅信号的频谱分析

本文共检测119例，其中冠心病69例（含室性心动过速17例）和正常人50例，分别在滤波后QRS综合向量模（A窗）和单导绝对稳过模（B窗）上选取≤40μV的120ms低振幅信号进行频谱分析，以X、Y、Z导联60～120Hz的平均高频面积（HFA）为检测参数，发现各组病人两窗口间有显著差异（p＜0.01）。若以HFA≥740和1240μV为两窗口阳性标准，则B窗对本组室性心动过速的敏感性、特异性和准确性为88.24、97.62和94.92％，A窗为64.71、95.24和86.44％，说明B窗优于A窗。     

Effects of Intraventricular Injection of Calmodulin Antagonist （Trifluoperazine） on Pregnancy in Rats

Injection of TFP (a specific antagonist of CaM) into the lateral ventricles of the rat brain on the fourth day of pregnancy causes marked antifertility effect in 83% of the rats (0% in the control group). Examination with the pontamone blue reaction for the implantation elucidated that the antifertitity effect was due to the blockage of implantation of the follicle. Injection of TFP into the lateral ventricles of the brain markedly reduced the concentration of CaM in hypothalamus, ovary and uterus. Serum progesterone was also reduced. However, injection glven on day 7 was ineffective to terminate the pregnancy. Injection given on certain time of pregnancy was able to reduce the cellular CaM content and to cause antifertitity. This finding demonstrated that CaM played an important rote during the course of pregnancy.     

人右心室肌纤维方向的解剖

对１１个人心标本沿右心室流入道和流出道各壁长轴纵行切开，再将各壁横切为上、中、下３份，各份按１ｍｍ厚度逐层切开，观察其各层肌纤维方向的角度并绘成坐标图。结果表明，右心室流入、流出道游离壁的肌纤维方向由浅入深基本上是渐变的。流入道游离壁的下１／３和流出道的上１／３，浅中层与内层之间可有纤维方向的突变。流入道隔壁的纤维方向从右向左逐渐移行，偶在左、右室内膜面有方向的改变。流出道右室面的中上部有一纤维方向变动较大的层次。对右心室各壁肌纤维方向的排列特或、分层、功能及其临床意义进行了探讨。     

核素心室造影对老年陈旧性心肌梗塞的诊断价值

应用平衡法核素心室造影观察２３例陈旧性心梗患者的左室收缩功能和舒张功能，结果发现ＯＭＩ组左室舒张功能均明显减退，高峰充盈率明显降低，ＰＦＲ是反映左室功能障碍的一个敏感且容易获得的参数。
