摘要
用NADPH-黄递酶组织化学法及整装铺片技术,对甘肃鼢鼠(Myospalax cansus)胃肠道肌间神经丛NOS阳性神经元的分布进行研究。结果显示,甘肃鼢鼠胃肠道肌间神经丛NOS阳性神经元分布广泛,形态多样,神经元大小不同,阳性神经节与阳性神经纤维束形成网络;胃肠道不同部位NOS阳性神经元密度有差异,结肠最高,直肠次之。从十二指肠至回肠段,NOS阳性神经元密度整体呈上升趋势;胃与空肠、十二指肠与盲肠间NOS阳性神经元密度无显著差异,其他各段之间差异显著。甘肃鼢鼠胃肠道肌间神经丛NOS阳性神经元分布与其他已研究动物的分布模式基本一致。
NADPH-diaphorase histochemistry and whole-mount preparation technique were used to investigate the distribution of NOS-positive neurons in gastrointestinal myenteric plexus of Gansu Zokor （ Myospalax cansus ）. The results showed that NOS-positive neurons with different shapes and sizes were widely distributed in the Gansu Zokor＇s gastrointestinal myentefic plexus. The positive ganglion and positive nerve fibers formed a complex meshwork. There were significant differences in the density of NOS-positive neurons among gastrointestinal tract segments except for Stomach-Ileum and Duodenum-Cecum .The density trend was：colon 〉 small intestine 〉 stomach 〉 caecum. The NOS- positive neurons increased from duodenum to ileum .The results suggest that the distribution of NOS-positive neurons in gastrointestinal myenteric plexus of Gansu Zokor is in similar pattern with that of other animals.
