摘要
用免疫细胞化学方法研究神经减压肽样免疫反应(NT-LI)细胞和终末在大鼠孤束核和最后区内分布。结果:孤束核内有许多NF-LI胞体和纤维终末,主要分布于该核最后区平面,多见于背侧亚核、内侧亚核和连合核。腹侧亚核内亦有大量NT-LI纤维终末分布。最后区内含有中等量NT-LI细胞和终末。孤束核和最后区间有往返的NT-LI纤维联系,两侧孤束核间也有NT-LI纤维相连。
Distribution of neurotensin-like immunoreactive(NT-LI)cells and terminals in the nucleus of solitary tract and area postrema of the rat was studied with immunocytochemical method. The results showed that many NT-LI cells and terminals were mainly distributed at the area postrema level in the nucleus of solitary tract,most of which were visualized in the dorsal subnucleus,medial subnucleus and commissural nucieus.Many NT-LI terminals were also present in the ventral subnucle- us.In the area postrema many NT-LI cells and terminals were observed,too.We discovered reciprocal connections of NT-LI fibers between the nucleus of solitary tract and the area postrema and direct con- nections of NT-LI fibers between the nuclei of solitary tract of two sides.
