Objective To study the morphology of myenteric nerve plexus in the congenital megacolon.
目的观察先天性巨结肠肌间神经丛形态学并分析其意义。
Objective to investigate the morphologic abnormalities of myenteric plexus in diabetic rats and to explore the mechanism of its effect on gastrointestinal motility.
目的了解糖尿病大鼠胃肠动力障碍时，肌间神经丛有无形态学异常并探讨胃肠功能异常的机制。
Results The ganglion cell wasn't found in myenteric nerve plexus of the constriction section. The diameter and the number of the nerve fibers were increased; Schwann's cells were increased.
结果先天性巨结肠狭窄部肠壁肌间神经无神经细胞，可见增多的直径增粗无髓鞘纤维，呈波浪状弯曲。
CRF could evoke a slowly activating depolarizing response that associated with enhanced excitability in myenteric neurons in colon. The cells excited by CRF were all expressed with CRF1 receptor.
CRF对豚鼠结肠肌间神经丛有很强的兴奋作用，可诱发慢的兴奋性去极化反应，而且CRF所兴奋的神经元均为表达CRF1受体的神经元。
