【摘要】 隔区和海马都是与疼痛和针刺镇痛有关的结构，为了提供更多的形态学基础，采用辣根过氧化物酶（ＨＲＰ）与还原型辅酶 Ⅱ黄递酶（ ＮＡＤＰＨ－ｄ）相结合法，逆行追踪大鼠隔区不同亚细胞群一氧化氮合酶（ ＮＯＳ）阳性神经元向背、腹海马及海马后部的投射。结果表明，隔内侧核、斜角带核垂直支背、腹侧部均有ＮＯＳ阳性神经元投射到背、腹海马及海马后部，其投射量约为隔－海马投射的１／３左右。更多还原

【Abstract】 The aim of this paper was to observe the projections of NOS positive neurons to the hippocampus from septal area. The projections were retrograde traced by combined method of horseradish peroxidase (HRP) and nicotinamide adenosine dinucleotide phosphate diaphorase (NADPH-d) in rats. After injecting of HRP into the dorsal hippocampus, the ventral hippocampus or the posterior part of hippocampus, the HRP-NOS double labeling neurons were distributed in the medial septal nucleus, the dorsal and ventral parts of ventical limb of diagonal band nucleus. The hippocampus received the projections of NOS positive neurons from the septal area, the number of septo-hippocampal projections of NOS positive neurons were about 1/3 of the total number of septo-hippocampal projections.更多还原
