为评价茶多酚对小鼠的抗辐射作用 ,将 60只小鼠作为抗辐射I组 ,动态观察白细胞数。另 60只小鼠为抗辐射Ⅱ组 ,进行存活试验。结果表明 ,小鼠经口给予不同剂量茶多酚 ,辐照后各次试验中小鼠血中白细胞数均与对照组无显著性差异 ,茶多酚在大剂量照射时对小鼠白细胞保护作用不明显。 0 83和 2 5 0mg kgBW组小鼠存活率和对照组间比较 ,均有极显著性差异 (P <0 0 1 ) ,对照组辐射后 30天无一存活。这一结果显示茶多酚能显著提高辐照小鼠存活率
In order to evaluate the anti-radiation effect of tea polyphenols on mice, 60 mice were used as anti-radiation I groups to dynamically observe the number of white blood cells. Another 60 mice were in Group II anti-radiation and were subjected to a survival test. The results showed that mice given orally with different doses of tea polyphenols had no significant difference in the number of leucocytes in the mice after each irradiation. The protective effects of tea polyphenols on the leukocytes in mice exposed to high doses of tea polyphenols were not significant. obvious. The survival rate of 0 83 and 250 mg kg BW mice was significantly higher than that of the control group (P < 0 01), and none of the control group survived 30 days after irradiation. This result shows that tea polyphenols can significantly increase the survival rate of irradiated mice.
