Abstract

The immunoreactivity of constitutive endothelial nitric oxide synthase (eNOS) was studied in the trigeminal ganglia (TG) of a crotaline snake, Trimeresurus flavoviridis. eNOS immunoreactivity was found in TG neurons of different sizes. The percentage of eNOS-positive TG neurons was significantly higher in the mandibular division than in the infrared-related divisions, the maxillary division and ophthalmic ganglion (p<0.001). These findings suggest that eNOS in the TG of crotaline snakes is involved in constitutive neurotransmission in the TG, and is minimally involved in processing in the infrared-sensory system.

摘要

研究了竹叶青蛇（Trimeresurus flavoviridis）三叉神经节（TG）中组成型内皮型一氧化氮合酶（eNOS）的免疫反应性。在不同大小的TG神经元中发现了eNOS免疫反应性。下颌神经分支中eNOS阳性TG神经元的百分比显著高于与红外线相关的分支、上颌神经分支和眼神经节（p<0.001）。这些发现表明，竹叶青蛇TG中的eNOS参与TG中的组成型神经传递，而在红外感觉系统的处理中参与程度最低。
