摘要: 目的:研究以原花青素为主要成分的某保健食品的抗辐射效应。方法:采用SPF级昆明种性成熟小鼠,以该保健食品人群推荐日摄入量扩大10、20、30倍分别作为低、中、高剂量组(0.15、0.30、0.45g/kgbw),小鼠连续经口灌胃15d后,除正常对照组外,其余各组均按照要求进行不同剂量的60Co照射,照射后各剂量组继续给予受试物,并在相应时间测定外周血白细胞数量、组织中超氧化物歧化酶(SOD)的活性以及血清溶血素。结果:与辐照模型对照组比较,以3.928Gy60Co剂量照射后15d,中、高剂量组小鼠外周血白细胞的数量明显增多,差异有显著性;以6.874Gy60Co剂量照射后7d,低、中、高剂量组能小鼠1%肝组织匀浆SOD活性明显增强,差异有显著性;以1.964Gy60Co剂量照射后15d,高剂量组小鼠的抗体积数显著高于辐照模型对照组的抗体水平,且差异有显著性(p<0.05)。结论:原花青素复合制剂对辐射损伤有辅助保护作用。

Abstract: Objective:The effects of proanthocyanidins on mice radiated by 60Co-γ was studied. Method:In this research, the materials were administered to the mice for the experiment, and then the mice were radiated with different doses at the 15th day. The number of peripheral white blood cell (WBC), the activity of superoxide dismutase (SOD) in serum and hemoiysin were determined after 30 d. Results:Compared with the control group, the numbers of WBC of mice with middle and high dose increase evidently with a significant diversity (p<0.05, p<0.01). The SOD activities of mice with low, middle and high dose in 1% liver suspension enhance evidently with a significant diversity (p<0.01, p<0.01, p<0.01). The content of antibody of mice with high dose increase significantly with a significant diversity (p<0.05). Conclusion:It is indicated that proanthocyanidins has an assistant protective effect on radiation damage of mice.
