In order to investigate experimentally that effect of Moschus, Bovis Calculus, Ursi Fel aqua-acupuncture on acutely damaged liver of rats induced by radix aconiti, the author gave Moschus, Bovis Calculus, Ursi Fel aqua-acupuncture according to method of manufacture stimulation to corresponding points, Kan-su (B18) and Ki-mun (Liv14), and carried out hematological, serological examination and electromicroscopical observation. The following results were obstained : 1. At 6 hours, cell organelles induced by radix aconiti toxicity prominently destructed in control and aqua-acupuncture treatment groups. 2. At 12 hours, cell organelles, destruction was some similarities between control group and aqua-acupuncture treatment group. 3. At 24 hours, rough endoplasmic reticulum and Golgi complex comparatively developed in aqua-acupuncture group treatment as compared with control group. 4. At 48 hours, cell organelles, destruction was recovered in aqua-acupuncture treatment group as compared with the control group and it was similiar normal findings. According to the above findings, it is considered that Moschus, Bovis Calculus, Ursi Fel aqua-acupuncture has effects of recovery of acutely damaged liver.
