Quantity and distribution of Purkinje conducting cells, contractile cardiomyocytes, connective tissue, capillaries and nervous structures in the conducting and working myocardium (CM and WM) of the subendocardial area of the anterior papillary muscles of the dog heart were studied. Predominance of the contractile cardiomyocytes volume density over that of Purkinje cells and a higher level of the volume density of capillaries and nervous structures were characteristic of WM comparing to CM while the connective tissue volume density was higher in CM than in WM. These variations in the distribution and quantitative content of tissue structures may determine the primary damage of the subendocardium as well as non-similar response of different animals to the same impact.
研究了犬心前乳头肌心内膜下区域传导心肌和工作心肌（CM和WM）中浦肯野传导细胞、收缩性心肌细胞、结缔组织、毛细血管和神经结构的数量及分布。与CM相比，WM的特征是收缩性心肌细胞的体积密度高于浦肯野细胞，且毛细血管和神经结构的体积密度水平更高，而CM中的结缔组织体积密度高于WM。组织结构分布和定量含量的这些变化可能决定心内膜下的原发性损伤以及不同动物对相同冲击的不同反应。
