[Effects of stimulation and cauterization of hypothalamic paraventricular nucleus on acupuncture analgesia].
The role of hypothalamic paraventricular nucleus (PVH) in acupuncture analgesia was investigated by local brain stimulation and cauterization. The results showed that electrical or L-glutamate sodium stimulation of PVH could enhance the effect of analgesia of Zusanli acupuncture, both in a dose dependent manner. Electrical cauterization of PVH decreased the effect of acupuncture analgesia, while removal of pituitary had no effect on the enhancing effect by L-glutamate sodium injection.
