摘要
目的 观察职业茶饮 4号辐射防护作用。方法 选取昆明种小白鼠 45只 ,随机分 3组①正常对照组、②放射模型组、③茶饮实验组。②、③组同条件给予一次性全身X射线照射 ,吸收剂量为 6Gy ,吸收剂量率为 2Gy/min。③组小鼠按每日 2mg/g bw给予职业茶饮 ,①、②给予普通自来水。观察小鼠血象及T -C亚群变化。结果 茶饮组小鼠放射反应明显减轻 ,小鼠存活率、外周血白细胞、血小板、T -C亚群较放射模型组明显增高 (P <0 0 5 )。结论 职业茶饮
Objective To observe the radiation protection effect of Occupational Healthy-tea No 4(OHT4) against injury by X-ray in mice.Methods 45 male mice of Kunming strain were divided randomly into 3 groups:①normal control,②irradiated model group and ③the experimental grouop.Mice of groups②③were irradiated once with 6 0 GyX-ray(2 0 Gy/min),meanwhile the mice of group③were treated with 2 mg/g bw of OHT4.Then the difference of survival rate and the changes of WBC、PLT、T-cells subgroups between 3 groups were observed.Results The OHT4 could lessen the radiation injury of X-ray and enhance the survival rate,the number of blood cells and T-cell immune function in mice.Conclusion OHT4 has the significant protective effect against X-ray radiation.
