猫延髓内脏带的化学神经解剖学

观察儿茶酚胺类、５－羟色胺以及神经肽等物质在猫延髓内脏带细胞，纤维和终末中的分布。方法：免疫组织化学ＡＢＣ法。结果：上述物质 较集中地分布于延髓中尾段一条从背内侧至腹外侧的弧形带状区内，结论：延人脏带是一相对独立的机能结构区。

Chemical neuroanatomy in the medullary visceral zone of the cat

AIM:The distribution of catecholamine(tyrosine hydroxylase as marker), serotonin and neuropiptides(substance P, neuropeptide Y and Met enkephaline) immunoreactive positive structures(nerve cell bodies, nerve fibers and terminals) were investigated in medullary visceral zone(MVZ) of the cat. METHODS: Immunohistochemical ABC method was used. RESULTS:The above mentioned immunoreactive structures were relatively densely distributed in the MVZ of the cat, which is an arc zone from the dorsomedial region to the ventrolateral region in the coronal section of middle and caudal medulla oblongata. CONCLUSION:It is suggested that the MVZ of the cat is a relatively independent functional structural area.
