| 摘 要： | 采用组织化学和免疫组织化学的方法对0、5、28日龄的仔猪小肠黏膜下神经丛中神经元类型的变化进行了定性研究和定量测定。结果表明，仔猪小肠黏膜下神经丛分为靠近环肌层表面的ESP(external submucosal plexus)和靠近黏膜肌层的ISP(internal submucosal plexus)；ESP与ISP神经纤维的性质不同，ESP主要是有髓神经纤维，而ISP主要是无髓神经纤维；随着日龄增长，黏膜下神经丛发育较快，ESP与ISP的差异日益显著。研究揭示：仔猪出生后黏膜下神经丛在形态和不同亚群神经元比例上均有一调整期，其生理学意义可能是使小肠黏膜下神经丛的功能日益完善。

| Abstract: | The changes of the types of the submucous neurons in the small intestine of the piglets aged 0 days, 5 days and 28 days were studied qualitatively and quantitatively by histochemical and immunohistochemical methods. The results were as follows: The submucous plexus includes external submucosal plexus (ESP) and internal submucosal plexus (ISP). The properties of the nerve fibers in ESP and ISP are different. Most of the nerve fibers in ESP are myelinated nerve fibers, while most of the nerve fibers in ISP are non-myelinated nerve fibers. As the piglets grow, the submucous plexuses develop fast. And the difference between ESP and ISP becomes more obvious. The study showed that the piglets altered the shapes and the ratio of the different types of submucosal neurons to make the function of the submucous plexuses more perfect. |
