Abstract:
The present study is designed to investigate the histochemical changes of cholinesterase, norepinephrine in nuc. Supraopticus and locus coeruleus of rats following electo-acupuncture and their possible relation to pain threshold. The preliminary results indicated that the elevation of pain threshold following electro-acupuncture concomittantly with increase in histochemical reaction of cholinesterase, and norepinephrine both in nuc. Supraopticus and locus coeruleus of electro-acupunctured rats. The increase in intensity was shown to be correlated with the elevation of pain threshold. The intensity of increased cholinesterase activity was more obvious in the animals with pain threshold elevated for above two folds than those elevated only one fold. On the other hand, the higher intensity of norepinephrine was obser ed in locus coeruleus with one fold of elevation of pain threshold. The significance of the changes in these two nuclei and their possibld function were briefly discussed.
