扬子鳄新皮质NOS、AChE阳性神经元的分布

目的 观察扬子鳄新皮质内一氧化氮合酶(nitric oxide synthase,NOS)和乙酰胆碱酯酶(acetylcholinesterase,AChE)阳性神经元的形态和分布,为扬子鳄脑的比较解剖学积累资料,为其机能研究提供形态学依据.方法 采用还原型尼克酰胺腺嘌呤二核苷酸黄递酶(NADPH-d)法和亚铁氰化酮法观察扬子鳄新皮质内NOS和AChE阳性神经元的分布和特征.结果 扬子鳄新皮质内有NOS和AChE阳性神经元分布,为大、中、小型细胞,以中小型细胞为主,胞体呈圆形、椭圆形、三角形和梭形.结论 扬子鳄新皮质内有NOS和AChE阳性神经元分布.

Distribution of NOS and AChE positive neurons in the neocortex of alligator sinensis

Objective To observe the distribution of nitric oxide synthase（NOS） and acetylcholinesterase（AChE） positive neurons in the neocortex of Alligator sinensis.Therefore,to accumulate data for comparative anatomy of Alligator sinensis＇ brain,and to provide morphological foundation for its functional research. Methods The nicotinamide adenosine dinucleotide phosphate diaphorase（NADPH-d） and acetylcholinesterase histochemical technique were used to observe the distribution and morphology of NOS and AChE positive neurons in the neocortex of Alligator sinensis. Results The NOS and AChE positive neurons were observed in the neocortex of Alligator sinensis.They were large,middle or small sized cells,but most of them were middle and small.The cell bodies were round,oval,triangular or fusiform in shape. Conclusion The neocortex of Alligator sinensis contains NOS and AChE positive neurons.
