Paravertebral (superior cervical and stellate), prevertebral (coeliac-superior mesenteric, inferior mesenteric) and pelvic (hypogastric) sympathetic ganglia of the rat were investigated by enzyme histochemistry to ascertain the distribution of nicotinamide adenine dinucleotide phosphate diaphorase (NADPH-diaphorase) activity. In the paravertebral ganglia the majority of the sympathetic neuronal perikarya contained lightly and homogeneously distributed formazan reaction product but there was a range of staining intensities amongst the neuron population. In contrast, in the prevertebral ganglia, intense NADPH-diaphorase staining was present in certain neurons. Firstly, a population of neurons of the coeliac-superior mesenteric ganglion complex were surrounded by densely NADPH-diaphorase-positive 'baskets' of fibres and other stained fibres were seen in interstitial nerve bundles and in nerve trunks connected to the ganglion complex. Secondly, in both the inferior mesenteric ganglion and hypogastric ganglion there were many very intensely NADPH-diaphorase positive neurons. Stained dendritic and axonal processes emerged from these cell bodies. In both ganglia this population of neurons was smaller in size than the lightly stained ganglionic neurons and commonly had only one long (presumably axonal) process. The similarity of these highly NADPH-diaphorase-positive neurons with previously described postganglionic parasympathetic neurons in the hypogastric ganglion is discussed.
通过酶组织化学方法对大鼠的椎旁（颈上神经节和星状神经节）、节前（腹腔 - 肠系膜上神经节、肠系膜下神经节）和盆腔（腹下神经节）交感神经节进行了研究，以确定烟酰胺腺嘌呤二核苷酸磷酸黄递酶（NADPH - 黄递酶）活性的分布。在椎旁神经节中，大多数交感神经元胞体含有轻度且均匀分布的甲臜反应产物，但神经元群体中存在一系列染色强度。相比之下，在节前神经节中，某些神经元存在强烈的NADPH - 黄递酶染色。首先，腹腔 - 肠系膜上神经节复合体的一群神经元被密集的NADPH - 黄递酶阳性“篮状”纤维所包围，并且在间质神经束和与神经节复合体相连的神经干中可见其他染色纤维。其次，在肠系膜下神经节和腹下神经节中都有许多非常强烈的NADPH - 黄递酶阳性神经元。染色的树突和轴突从这些细胞体发出。在这两个神经节中，这群神经元的大小比轻度染色的神经节神经元小，并且通常只有一个长的（可能是轴突的）突起。讨论了这些高度NADPH - 黄递酶阳性神经元与先前描述的腹下神经节节后副交感神经元的相似性。
