Observations on the coronary arteries of 100 embalmed and 20 fresh hearts of Chinese children were made. The results were as follows: 1. The point of origin of the coronary arteries was found horizontally at the middle third of the aortic sinus in 90.5%, and vertically below the upper margin of the aortic sinus in 91.5%. The diameter of the opening of the left coronary artery was greater than that of the right side in 77%' lesser than that of the right side in 4%, and equivalent to that of the right side in 19%. 2. The accessory coronary arteries occurred in 47% of the cases, and all were found on the right side. In one case, an accessory coronary artery distributed to the anterior wail of the right atrium. 3. Type II, i.e. the posterior wall of the left ventricle which was mainly supplied by the right circumflex branch, was the most common type of distribution. It occurred in 59%. 4. The interventricular septum was supplied by both the anterior and posterior descending branches, the proportion of which is determined by the length of the two descending branches. 5. The left coronary artery divided into 3 main branches (anterior descending, diagonal, left circumflex) in 56%. 6. Ramus septi fibrosi which originated from the right circumflex was found in 97% and from the left circumflex in 3%. 7. Ramus ostii cavae superioris was a constant branch, originating from the right side in 64% and from the left side in 36%. 8. The difference in number of the blood vessels to the left and right ventricles was not obvious.

用防腐了的100個中國兒童心臟,20個新鮮心臟,對心臟冠狀動脈的分佈類型作了觀察,其結果如下: 1.冠狀動脈的起點在横的位置以主動脈竇的中央爲最多,佔90.5%,縱的位置是在主動脈竇和主動脈分界綫以下的最多,佔91.5%。左冠狀動脈口的口徑大於右側的是77%,小於右側的4%,左右相等的19%。 2.副冠狀動脈的出現有47%,全部在右側,其中1例副冠狀動脈分佈右心房前壁。 3.在中國兒童冠狀動脈的分枝類型型II佔59%,也就是說左室後壁主要是由右旋枝分佈的較多。 4。前、後降枝分佈室中隔的範圍和兩個降枝的長短成正比例。 5.左冠狀動脈分爲三個主幹(前降枝,斜角枝,左旋枝)的佔56%。 6.縱隔纖維枝有97%來自右旋枝,3%球來自左旋枝。 7.上腔靜脈口枝是心房的一個固定枝,起於右側冠狀動脈的64%,左側的36%。 8.左右冠狀動脈的分枝之間經常存在着吻合。 9.左右心室的血液供給沒有顯明量的差別,只是在動脈口徑上稍有不同。

Out of 18 animals, 12 survived over 5 days after 2nd operation....

1. Therty-three adult male rabbits were used for this experiment. The animals were divided into four groups. In the first experimental group, a piece of its own spleenic tissue was implanted to the myocardial surface in each animal after the internal mammary arteries had been ligated bilaterally. Within one to four weeks after the first operation, the animals were subjected to ligation of the circumflex branch of the left coronary artery. Out of 18 animals, 12 survived over 5 days after 2nd operation. In the second experimental group the same procedure was repeated as group 1, except the implantation of the spleenic tissue. Two animals survived out of 5 operated. In the control groups (the 3rd and 4th groups) no operation was performed before ligation of the branches of the coronary artery. In the 3rd group, after the ligation of the ant. descending branch, 3 out 4 animals survived over 5 days, while in the 4th group, after ligation of circumflex branch none survived over 5 days in 6 animals operated. 2. In group 2, X-ray photographs indicate that collateral circulation was established through the anastomosis between pericardial vessels and branches of the coronary artery. 3. The X-ray photographs of the experimental group 1 proved the establishment of collateral circulation between ant. descending branch and circumflex branch of the left coronary artery by the vasculature in the spleenic implantation. 4. As is shown by periodic acid Schiff reaction, (1) in both control groups, the glycogen granules in the area of coronary occlusion were more reduced than in the border area, (2) in the second experimental group the glycogen granules in the area of coronary occlusion have slightly increased in comparison with those in same area in the control group and (3) in the first experimental group the glycogen granules in the area of coronary occlusion were increased more than in the same area in the second group. These changes offer convincing elucidation that in the first and second groups, owing to the production of the intercoronary collateral circulation or the hemodynamic effect, the blood supply to the area of the coronary occlusion was ificreased.

1.第一组实验结果证明,于左冠状动脉的二枝之间,在实验性乳房内动脉结扎后所产生的血液循环动力学效应的基础上借移植脾内的血管建立了侧枝循环。为冠状动脉急性闭锁区提供了足够的血液供给。使残恬五天以上的动物提高到66.6 % o 2.第二组的实验结果说明,在结扎乳房内动脉后所产生血液动力学(hemodynamic)的效应通过心包隔动脉侧压(lateral-pressure)和血流量的增加而开伐和凿通了心包血管床并经心包翻拆处与冠状动脉系统相交通。对冠状动脉闭锁区的心肌表层提供了一定的血液量。3.在各组动物冠状动脉的闭锁区用PAS反应方法所显示的糖原颗粒的变化进一步地证实了第二组闭锁区的贫血状况得到一定的改善而第一组获得了此较彻底地改善。

Salvia compositus is the water extract of a mixture of the Chinese medicinal herbs Salvia Miltiorrhiza and Delbergia Odorifera, which had been used for the treatment of coronary heart diseases including myocardial infarction. Usually the subjective complaim of patients suffering from infarction could be somehow relieved promptly after intravenous injection of Salvia compositus This paper presents the results of experiments concerned with the analysis of the possible mechanisms of this effect. Salvia compositus exhibited no obvious effect on the tension and the frequency of contraction of the heart in situ, the ischemic changes of the electrocardiogram elicited by the ligation of the anterior descending branch of the left coronary artery, the membrane and action potential of the myocardial cells and the oxygen consumption of the slices and homogenates of myocardial cells and brain tissues as well as the slices of the diaphragm. However, the drug showed marked effects on the electrical activities of the cerebral cortex, including depression of the spontaneous activities, increase of the threshold of the repetitive discharges elicited by direct cortical stimulation and enhancement of the sensory evoked cortical responses. Thus it seems that Salvia compositus exerts its prompt clinical curative effects via its depressant effect on the cerebral cortex.

本文报告我们对冠心病患者使用复方丹参后较快(如数小时内)出现的疗效的作用机理实验分析的结果。所用药物内含丹参和降香,静脉推注复方丹参一次或每隔十分钟至一小时反复推注数次,对大白鼠和兔在位心脏的收缩张力和心率都没有影响。对因呼吸通气量不足或结扎冠状动脉分支引起的心电图缺血性变化也没有作用。药物对离体豚鼠在心室乳头肌的膜电位、动作电位、心肌和脑切片、匀浆以及膈肌切片的氧耗量都没有影响。药物延长小白鼠在密闭容器中的存活时间的作用,可以为不到麻醉剂量的戊巴比妥钠所模拟。药物使免大脑皮层自发电活动减小,重复刺激引起的后发放的阈值提高,感觉刺激的诱发电位增大。从以上这些结果来看,我们认为复方丹参是通过它对大脑皮层的压抑作用发挥其快速疗效的。
