大鼠“内关”穴区一氧化氮合酶阳性神经的来源

Source of Positive Nerve of Nitric Oxide Synthase on “Neiguan”Point Area in Rats

采用辣根过氧化物酶 (HRP)逆行追踪与还原型尼克酰胺嘌呤二核苷酸脱氢酶 (NADPH-d)相结合方法 ,观察大鼠“内关”穴区一氧化氮合酶 (NOS)阳性神经纤维的来源。结果 :当 HRP注入“内关”穴后 ,在脊神经节的颈 6至胸 1 (C6-T1)节和脊髓前角观察到 HRP-NOS双标记神经元。结论 :“内关”穴区有 NOS阳性感觉和运动神经纤维分布。

Source of positive nerve fiber of nitric oxide synthase ( NOS) on“Neiguan” ( PC6) point area in rats was observed by retrograde trace of horse radish peroxidase( HRP) combined with reduced nicotinamide adenine dinucleotide dehydrogenase.Results indicated thatafter injection of HRP into“Neiguan”point,HRP- NOS double label neurons were observed in spinal gangia C6- Ti and anteria horn of the spinal cord.It is suggested that“Neiguan”point area containts positive sensory and motor neuron fibers.
