Acetylbenzoylaconine, 2-aminoethylisothiouronium bromide hydrobromide (AET), $eta$-mercaptoethylamine HCI (MEA), L-thiazolidine-4-carboxylic acid (thioproline)의 Co-60 감마선에 대한 방어효과를 5-6주된 백색마우스를 이용하여 연구하였다. 백색마우스에 대한 acetylbenzoylaconine의 독성실험 결과 LD$_{50}$은 2.5mg/kg이었다. 위의 4종 실험약제를 백색마우스 복강내에 주사한 후 Co-60 감마선 800 rad를 전신조사하고 30일간 계속 관찰하여 실험군들에 대한 생존계수를 계산하였다. 이 생존계수치로 방사선장해에 대한 방어계수를 계산한 결과 acetylbenzoylaconine AET, MEA, thioproline에 대해 각각 2.24, 2.95, 2.78, 1.23 으로, acetylbenzoylaconine은 백색마우스를 Co-60 감마선장해로 부터 방어할 수 있는 능력이 있음을 알았다.
The protective effects of acetylbenzoylaconine, 2-aminoethylisothiouronium bromide hydrobromide, $eta$-mercaptoethylamine HCI, and L-thiazolidine-4-carboxylic acid were studied on the white male mice, aged 5-6 weeks. The toxicity test of acetylbenzoylaconine revealed that the LD$_{50}$ was 2.5 mg/kg of body weight. After the administration of test substances, mice were irradiated with whole body dose of 800 rad by the Co-60 source. Observing the number of surviving mice for 30 days, the survival coefficients for the test groups were calculated and with these the protective coefficients against radiation injury, PCR, were also calculated. The PCR values are 2.24, 2.95, 2.78, and 1.23 for acetylbenzoylaconine, 2-aminoethylisothiouronium bromide hydrobromiide, $eta$-mercaptoethylamine HCI, and L-thiazolidine-4-carboxylic acid respectively. These values reveal that the acetylbenzoylaconine has protective potency against radiation injury on white male mice.
