放射線障害防護薬剤に関する研究(第27報)放射線障害に対する各種漢方方剤のメタノールエキスの延命効果 Studies on Chemical Protectors against Radiation. XXVII. Survival Effects of Methanol Extracts of Various Chinese Traditional Medicines on Radiation Injury
The survival effect of mice irradiated with a lethal dose of X-ray was studied by use of 60 kinds of Chinese traditional medicines. Methanol extracts of these medicines were prepared, and then each extract injected intraperitoneally into male mice before or after whole-body irradiation. As a result of these studies, the survival effects with Ogi-kentyu-to, Simotu-to, Sessyoin, Zokumei-to and Boi-ogi-to were observed by intraperitoneal injection before irradiation. Of these effective methanol extracts, only Zokumei-to was shown to have a significant survival effect by intraperitoneal injection after irradiation.
