The Study On The Morphology And Distribution Of NNOS-positive Neurons In The Brain Of Rabbit

Nitric oxide, a new type gas molecules, is a information transmission substance, which is a common, widely distributed in central nervous system, and plays a very important role. Therefore, it is being payed more and more attention. Nitric oxide catalyzes the production of arginine under the action of nitric oxide synthase, and the nitric oxide synthase had three subtypes: types of neuron,types of abduction,type of endothelium, and types of neuron has been found found chiefly in the neuron. This experiment has studied, systematacially, the distribution and embryonic change of positive neuron—neuronal nitric oxide synthase in cerebral cortex of rabbits and the orientation,conformation and distribution and embryonic change of positive neuron-neuronal nitric oxide synthase in cerebral cortex of nuclei nervorum cranialium of rabbits by SABC immunohistochemical method.This study has revealed, completely, the regular of embryonic change of positive neuron-neuronal, and probed into the function of NO and the mechanism of NO in the central nervous system, All this research work will provide the gist of the study of nervous system disease, especially the study of the physiology of nervous pathology.The first experiment has studied, detailedly, the morphosis,distribution and embryonic change of the positive neuron—neuronal nitric oxide synthase in cerebral cortex of rabbit , the result showed that immune-positive neuron of nNOS and neuron twig have been found in cerebral cortex of rabbits. The color of immune-positive neuron of nNOS was brown and the color of nucleolus was weak, and the conformation was variegated. The soma showed different figure such as spindle,triangle,rotundity,oval and pear shape. The length and number of apophysis was different, furthermore, neurofibril of immune-positive neuron of nNOS shows brown pinch-and-swell form and distributes interlacedly. We can draw...
