The electrophysiological techniques was utilized to study the mechanism of clectroacupuncture anaesthesia of uterus in the rat.The uterine contractive effects has been observed as follows:the electroacupuncture of BL-32 point can gradually decrease the intrauterine pressure and the amplitude of uterine contraction.But these effects also cart be abolished by sympathetomy

spinalized or cut down the dorsal sacral nerve.That shows the effects of acupuncture may be transferred to the spinal cord from dorsal sacral nerve

through the control of central nervous eyetem

and affect the function of uterus by the efferent route of sympathetic trunk.
