【Abstract】 The effect of acupuncture analgesia in rat was assessed by the tail-flick method and was triedto correlate with the changes in the cerebral content of serotonin(5-HT)and the endogenous opiate-like substances(OLS),Measures were taken to lower the cerebral content of 5-HT or to block theeffect of OLS to see their effect on acupuncture analgesia.The interrelationship between 5-HTcontent and OLS activity was also monitored in different physiological and pharmacologicalsituations.The results indicated that the effect of acupuncture analgesia was intimately related to thecerebral 5-HT content and OLS activity and the extent to which they were mobilized during thecourse of acupuncture.There was an intimate interrelationship between the cerebral 5-HT contentand the OLS activity and these two neurochemical substrates seemed to be functionally compensatoryto each other.更多还原
