摘　　要：目的　探讨一氧化氮合酶 (NOS)阳性神经元在大鼠延髓网状背侧亚核传入投射通路上的分布。　方法　还原型尼克酰胺腺嘌呤二核苷酸脱氢酶组织化学和荧光金 (FG)逆行追踪法相结合方法。　结果　在脊髓后角Ⅰ层、Ⅹ层以及中缝背核、中缝线形核、中缝隐核等处有不同比例的NOS FG双标神经元 ,在中脑导水管周围灰质存在较多NOS单标和FG单标神经元 ,但未见NOS FG双标神经元。Objective To observe the distribtuion of NOS positive neurons in the projecting pathway to the subnucleus reticularis dorsalis(SRD) in the rat. Methods We used a double staining technique combined retrograde tract tracer and NADPH d histochemistry. Results FG/NOS double labeled neurons were found in the laminae Ⅰ,Ⅹ of spinal cord,dorsal raphe nucleus(DR),linear raphe nucleus(LR),and raphe obscurus nucleus(RO).In the periaqueductal gray(PAG),there were many FG labeled or NOS labeled neurons,but no FG/NOS double labeled neurons were found.Conclusion\ NO might play a role in the pathway of afferent projections of the SRD.\;[
