本文用119例大鼠观察了左心室壁内血管和结扎左冠状动脉后心壁内血管的变化。动物按不同的间隔时间处死。其中75例心脏经主动脉灌注20%中国墨汁明胶液后作火棉胶切片;另44例心脏直接固定作石蜡切片观察。正常大鼠左心室游离壁内血管类型与人及家兔基本相似。室间隔内血管分布与家兔相似。左心室毛细血管数目为3903±48/mm~2,毛细血管与心肌纤维数目比例约为1:1。毛细血管互相吻合成网,其走行与心肌纤维方向一致。结扎大鼠左冠状
In this paper, 119 rats were observed in the left ventricular wall and the left coronary artery ligation of the left ventricular wall after the changes in blood vessels. Animals were sacrificed at different intervals. Among them, 75 cases were infused with 20% Chinese ink gelatin solution through the aorta, and the other 4 cases were directly fixed with paraffin sections. Normal left ventricular free wall type of blood vessels and human and rabbit similar. Intraventricular septum vascular distribution similar to rabbits. The number of left ventricular capillaries was 3903 ± 48 / mm ~ 2, the ratio of capillary to myocardial fibers was about 1: 1. Anastomosis of capillaries into a network, its line of travel and myocardial fibers in the same direction. Left ligation of rats
