Anti-radiation effect of resveratrol / 中南大学学报(医学版)

ABSTRACT

OBJECTIVE@#To explore the anti-radiation protective effect of resveratrol (RES).@*METHODS@#(60)Co-γ irradiated injury model was established. A total of 200 Kunming mice were randomly divided into 4 groups (50 in each group): Group I, II, III, and IV. Each group was sub-divided into 5 groups: a normal control (n=10), an irradiated model control group (n=10) and 3 treatment groups of RES (50, 100, and 300 mg/kg RES treatment groups, 10 in each group). RES was orally administered daily for 30 d in the RES treatment groups and 1% sodium carboxymethylcellulose was orally administered in the normal control and irradiated model group. Thereafter, except the normal control group, the mice in other groups were exposed to different dosages of (60)Co-γ once, and the gavage was continued until the end of different experimental periods. Peripheral leucocytes, nucleated bone marrow cells were counted; superoxide dismutase (SOD) activity and hemolysin in the serum were determined at different time.@*RESULTS@#Under the different dosages of (60)Co-γ irradiation and the provisions of the experimental conditions, the leucocyte count was (1.69±0.82)× 10(9) and (1.61±0.51)× 10(9)/L in the 100 and 300 mg/kg RES treatment groups, which was significantly increased, when compared with the irradiated model control group [(0.73±0.69)× 10(9)/L] ( P0.05).@*CONCLUSION@#At 100 and 300 mg/kg, RES has good anti-radiation effect.
