目的　观察金华猪心内生长抑素 (SS)免疫反应 (IR)纤维和细胞分布。　方法　ABC免疫组织化学染色法。　结果　SS IR阳性纤维分布于左右心房、心室和冠状窦 ,以心房为多。阳性纤维呈线状或点线状 ,主要分布于心肌层。此外 ,右心房内有散在分布的神经节 ,其内有数 10个SS阳性神经元。　结论　猪心内有SS IR阳性纤维和神经元 ,与人心内类似 Objective To observe the distribution of somatostatin (SS) immunoreactive (IR) fibers and cells in Jinhua pig heart. Methods ABC immunohistochemical staining. Results SS IR positive fibers distributed in the left and right atria, ventricles and coronary sinus, with atrial as much. Positive fibers were linear or point line, mainly in the myocardium. In addition, there is a scattered distribution of ganglia in the right atrium with several 10 SS-positive neurons. Conclusion There are SS IR positive fibers and neurons in pig heart, similar to those in human heart
