Structure of the neurons of the sympathetic ganglia in guanethidine chemical sympathectomy

As demonstrated the investigation of cell composition of the cranial cervical, cervico-thoracic and the 3d thoracic ganglia of the sympathetic trunk in mature Wistar rats under guanethidine chemical sympathectomy, there are intraganglionic reconstructions and changes in the value of the subpopulations of neurocytes in the preserved cell population. Ratio of the neuronal subpopulations studied with various character of changes revealed adaptive-compensatory processes, developing in the course of sympathectomy at the level of population. The ways of realization of the populational and cellular levels of compensation are considered. The wavy character of sympathectomy is thought to reflect integral behavior of the nervous cells subpopulation in the course of development of homeostatic reactions.
