用免疫组织化学 (ABC)法观察金华猪心精氨酸加压素 (AVP)免疫反应 (IR)阳性的神经纤维和细胞的分布 .结果发现 AVP- IR纤维分布于左右心房、心室、冠状窦和冠状动脉周围 ,但以心房为多 .右心房近冠状窦处见散在分布的阳性神经细胞 .IR纤维呈线状、点线状或交织成网络状 ,主要分布在心肌层及外膜下肌层 ,多伴血管走行 ,或攀附血管走行 .这一发现提示金华猪心有与人心相似的神经肽 ,这为研究金华猪心的神经肽在心血管系统中的作用提供了形态学基础 .
The distribution of AVP immunoreactive (IR) -positive nerve fibers and cells in Jinhua pig heart was observed by immunohistochemistry (ABC) method. The results showed that AVP-IR fibers distributed in the left and right atria, ventricle and coronary sinus And around the coronary artery, but to the atrium as the right atrium near the coronary sinus see scattered positive neurons.IR fibers were linear, dotted or interwoven into a network, mainly in the myocardium and subepidermis Layer, with the blood vessels running along, or cling to the blood vessels to walk.The discovery suggests Jinhua pig heart similar to the human neuropeptide, which provides a morphological basis for the study of Jinhua pig heart neuropeptide in the cardiovascular system.
