本文用光镜和扫描电镜对牦牛幼牛和成年牦牛左心室壁微血管进行了观察。采用Image Pro-Plus 5.0软件测量不同微血管直径和三层心室心肌毛细血管密度。结果表明，成年牦牛心脏小动脉和毛细血管前小动脉的平均管腔直径大多大于幼龄牦牛。相反，幼龄牦牛心脏毛细血管直径大于成年牦牛心脏毛细血管直径。成年牦牛心肌毛细血管密度显著高于对照组(P
Observations on the microvasculature in the left ventricular wall of infant and adult yaks under light and scanning electron microscope (SEM) were presented. Moreover, the diameter of different microvasculature and the density of the capillaries in three layers of the ventricular myocardium were measured using Image Pro-Plus 5.0. The results showed that the average luminal diameter of arterioles and precapillary arterioles in adult yak's hearts were, in most cases, larger than those in infant yaks. On the contrary, the diameters of the capillary in infant yak's hearts were larger than those in adult yaks. The density of capillary in the myocardium of adult yak's heart had significantly higher values (P
