To evaluate the radioprotective effects of Bujeongsaengjintang studies were done experimentally. The results were obtained as follows: 1. WBC, Platelet and RBC were significantly increased in Bujeongsaengjintang treated group as compared with control group after exposure to radiation by Liniac. 2. By FACS analysis of splenic leukocyte after exposure to radiation by Liniac, T cell, T-helper cell and macrophase were significantly increased in Bujeongsaengjintang treated group. 3. In histological changes of ileum and jejunum of Balb/C mice after exposure to radiation by Liniac, exclusion and fusion of villi were decreased in Bujeongsaengjintang treated group as compared with control group. From above results, it is suggested that Bujeongsaengjintang is available to a clinic for the protection from damage by radiotherapy to cancer.

Radioprotective effects of amentoflavone were investigated by examining cell viability, apoptosis, cell cycling concentrations of intracellular ROS (reactive oxygen species), and relative mitochondrial mass by flow cytometry after $^{60}Co$ irradiation. Pretreatment with amentoflavone 24 hours prior to 8 Gy $^{60}Co$ ${\gamma}$-ray irradiation significantly inhibited apoptosis, promoted the G2 phase, decreased the concentration of ROS and mitochondrial mass. These results collectively indicate that amentoflavone is an effective radioprotective agent.

Ginseng proteins were isolated and partially purified to obtain two fractions, namely GI and GII. Radioprotective effects of these fractions were examined on $\gamma$-ray irradiated ICR mice by observing 30-day survival rates after irradiation. Also investigated were the effects of GI fraction on the recovery of radiation damage. As the results, the GI fraction showed strong protection against radiation indicated by the increment of 30-day survival rates, while the GII fraction did not. The GI fraction enhanced the recovery of body and splenic weights and increased the amount of DNA in liver significantly. It also helped to recover the damage done on erythrocytes by increasing the number to normal in short period, however, it had no effect on the recovery of leukocyte counts.

[6]-Gingerol, a major polyphenol of ginger (Zingiber officinale), exhibits a variety of biological properties including anti-oxidant, anti-inflammatory and anti-cancer activity. However, the radioprotective effect of [6]-gingerol is still unknown. The aim of this study was to investigate the radioprotective effect of [6]-gingerol against radiation-induced cell cytotoxicity and oxidative stress in HepG2 cells. [6]-Gingerol pretreatment attenuated radiation-induced cell cytotoxicity caused by 5Gy (half lethal dose, $LD_{50}$ of HepG2 cells). The measurements of superoxide dismutase (SOD) and catalase (CAT) activity were also performed. The results showed that [6]-gingerol pretreatment reduced increasing SOD and CAT activity after exposure of IR, indicating that [6]-gingerol protected oxidative stress by regulating cellular antioxidant enzyme (SOD and CAT) activity. These findings suggest that [6]-gingerol acts as a radioprotector by attenuating cell cytotoxicity and oxidative stress.

Studies were Performed to determine whether the water fraction of Panax ginseng Protected radiation damage to hair medullar cells of N:GP(s) mice after in vivo irradiation with $^{60}Co{\;}{\gamma}-rays$. The hair follicles in the middle of the growth cycle were analysed 3 days after 3 Gy irradiation for the changes in the number of cells in the forming medulla of the hair in the region just above the germinal matrix of the growing (anagen) hair follicle. The radioprotective effect of ginseng was compared with the irradiation control. The medullar cell count per unit length ($100{\;}\mu\textrm{m}$) of hair follicle was higher in the pretreated-groups of ginseng, both oral (2 mg/ml of drinking water, p<0.05) and intraperitoneal (0.3 mg/head, p<0.001) treatments, than the irradiation control. These data suggested that the water fraction of Panax ginseng may reduce cell damages on the body surface caused by ${\gamma}-rays$.
