以躯体、内脏伤害性刺激引起中枢神经系统产生电变化方面的报导不多。为此我们选用佐剂关节炎(Adjnvant Arthritis.AA)大鼠为慢性痛的动物模型

探讨慢性Adjuvant arthirts (AA) rats were used as the chronic pain model. The cortical and hippocampal (HPC) EEG were recorded. The behaviour and local inflammatory reaction were observed. The results showed an arousal response of desynchronization of the ECoG and HPC EEG in the AA rats

the delta waves were decreased and bata waves increased significantly. However

the inhibited effect to the desynchronization were showed could be inhibited by the electro-acupuncture (EA) on bilateral Zusanli points and morphine in the AA rats. The results suggeste that the cortex and hippocampus participate in the modulating action of chronic pain

and the EA has an analgesic action.
