[Effects of gosha-jinki-gan on urinary bladder contraction in dogs].
The effects of Gosha-Jinki-Gan on the urinary bladder contraction in anesthetized dogs were studied to elucidate the mode of action. The bladder contraction was induced by electrical stimulation of the left distal end of the pelvic nerve under the bilateral pelvic nerve and hypogastric nerve transections, or by the infusion of acetylcholine (200 micrograms) in to the abdominal aorta. The bladder contraction induced by pelvic nerve stimulation was significantly inhibited by 10 and 100 mg/kg of intravenous Gosha-Jinki-Gan administration. A similar phenomenon was observed by the administration of atropine sulfate (0.1 mg). The acetylcholine-induced contraction was significantly inhibited by administration of 100 mg/kg of Gosha-Jinki-Gan. These findings suggested that Gosha-Jinki-Gan inhibits the urinary bladder contraction induced by the stimulation of cholinergic nerve.
