title: Preliminary study on the anti-radiation effect of jen-sheng-yang-yung-tang.
abstract: Six to seven week old male mice of ICR strain were exposed to different doses of x-rays to determine if jen-sheng-yang-yung-tang could be a modifier in the elimination of radiation damage. Colony forming units of bone marrow cells in the spleen (CFUs) were measured before and after x-ray irradiation with intraperitoneal injection of 10 mg/20 g or 20 mg/20 g body weight of jen-sheng-yang-yung-tang, once a day for seven consecutive days. The recovery of CFUs and hemocytes counts by 4 Gy irradiation with jen-sheng-yang-yung-tang administration was faster for a concentration of 20 mg/20 g than 10 mg/20 g. The measurement of 10-day CFUs showed an increase of radiotolerance in the treatment of 20 mg/20 g administration before x-ray irradiation. The injection of jen-sheng-yang-yung-tang accelerated the recovery of hemocyte counts in mice irradiated with 4 Gy x-ray; the effect was especially profound for leukocytes with 20 mg/20 g jen-sheng-yang-yung-tang administration after irradiation.
