Radiation Protection and Recovery Effects of Red Ginseng, Saururus chinensis (Lour.) Baill. and Rubus coreanus Miq. Mixed Extracts in SD Rat irradiated to Gamma-ray 6 Gy

The purpose of this study is to confirm the radiation protection and recovery effects of natural mixed radiation protection agents. Red Ginseng, Saururus chinensis (Lour.) Baill. and Rubus coreanus Miq. mixed extract was orally ad- ministered to male SD rats and changes were observed in the blood, small intestine and prostate. The experimental group was organized into a general control group (NC Group), mixed extract administration group (RSR Group), 6 Gy irradiation group (IR Group), and irradiation group after administration of the mixed extract (RSR+IR Group). Among them, the RSR Group and RSR+IR Group were orally administered 2 cc (36.6 mg/day/250 g) of the extract once for two weeks at the same time, and at the end of administration, the IR Group and RSR+IR Group were irradiated with 6 Gy whole body radiation. Looking at hematological changes, the RSR + IR Group showed higher recovery and higher levels of white blood cells and platelets than the IR Group. And SOD levels showed high activity in the group administered the extract. Looking at the small intestine, compared to the IR Group, the RSR+IR Group shows better protection and recovery of small intestine villi length. Likewise, in the prostate, there is less cell damage in the RSR+IR Group, and on the 21st day, the prostate spacing is constant, showing a similar pattern to the NC Group. It is believed that the mixed extract used in the study has radiation protection and recovery effects in male SD rats and will be helpful in the study of mixed radiation protection agents.
