ABSTRACT
Objective To explore a better method to diagnose the brachial plexus injury as pre-or post-ganglionic,which is quick,simple,quantitative,cheap and accurate.Methods Forty-five SD rats were divided randomly ino pre-or post-ganglionic brachial plexus injury models group,and the choline acetyl- transferase(CHAT)activity was detected by using the radioisotope after different days.Results The ChAT activity of two groups both fall day by day:in the pre-agnglionic group,it falls quickly,and reach 1/10 of nor- mal(675?258)cpm;in the post-ganglionic group,it falls slowly,and reach 1/2 of normal even after 90 days (4906?1119)cpm.Conclusion Intra-operative measure of ChAT can be used to differentiate pre-or post- ganglionic brachial plexus injury.
