[Effect of acupuncture on the contents of vasopressin and oxytocin in the rat].

This work was to investigate the change of the contents of vasopressin and oxytocin during acupuncture in rat. Acupuncture could not only cause a change of immunoreactive arginine vasopressin, but also cause a change of immunoreactive oxytocin in many regions of rat brain. These results suggest that arginine vasopressin and oxytocin might be through the central nervous system to participate acupuncture analgesia.
