ASSESSMENT OF PERIPHERAL NERVE STATE BASED ON ACETYLCHOLINESTERASE ACTIVITY

Abstract

The aim of the study was to establish the possibility of assessment of the state of peripheral nerve based on acetylcholinesterase (AChE) activity. In a series of experiments on rats, the method for demonstration the of AChE activity on the sections of the peripheral nerves was modified (priority reference № 2013157128 of 23.12.13) and it was shown that the reaction intensity depended upon the state of the nerve fibers. During the atrophic processes, the enzyme activity decreased, while it was dramatically increased during fiber sprouting. It was shown that by using the intensity of AChE reaction as a criterion, the state of the nerve could be evaluated within 1-2 hours, which may be used later during the reconstructive operations (intraoperatively).
