摘要
以还原型尼可酰胺腺嘌呤二核苷酸磷酸硫辛酰胺脱氢酶（NADPHd）组织化学技术系统观察了大鼠心房壁与心室壁各层、冠状动脉、主动脉与肺动脉根部、窦房结、房室结及Purkinje细胞的一氧化氮（NO）能神经构造。证实心脏各部均接受NO能神经支配，传导系与冠状动脉壁的神经纤维最为丰富；心内神经节中25.8％为NO阳性神经细胞，部分NO强阳性神经细胞突起穿过神经节进入心房肌层，终于心肌细胞表面。
By means of NADPHd histochemical technique, we have systematically observed nerve structure generating the exotic messenger molecule nitric oxide and innervating cardiac atrium and ventricle, coronary artery, the roots of pulmonary and aortic arteries,sino-atrial node, atrio-ventricular node and cardiac PurkinJ cells in the ventricle. Nerve structures contatining NADPHd innervate every part of the heart. The richest nerve fibers were found in wall of coronary artery and in cardiac conductive system. 25.8% intrinsic car diac ganglionic cells are NADPHd positive neurons. Processes of some nerves with strong NADPHd positivity passing through intrinsic cardiac ganglion go to myocardium and end at the surface of cardiac muscle cells.
