本文对清醒家兔脑内4个核团分别进行灌流,并测定其中的内啡肽含量,看到:1.针刺镇痛时中央灰质灌流液中的内啡肽组分1明显增加,这种增加且与镇痛作用有关.2.针刺镇痛时尾核灌流液中内啡肽组分1有增加趋势。3.电针促使伏隔核中内啡肽组分1释放增加,但这种增加与镇痛作用的关系不明显.4.电针对杏仁核中内啡肽释放量无明显影响。 In this paper, four nuclei in the brain of conscious rabbits were perfused respectively, and the content of endorphins in them was determined. It was found that: 1. The endorphin component 1 in the central gray matter perfusate significantly increased during acupuncture analgesia, which Increased with the analgesic effect.2.Endorphin fraction 1 in caudate nucleus perfusion fluid increased with acupuncture analgesia. Electroacupuncture promoted the release of endorphin 1 in nucleus accumbens, but the relationship between this increase and analgesia was not obvious.4.Electro-acupuncture had no significant effect on the release of endorphin in amygdala.
