富硒米对大鼠正常生长、血常规和T淋巴细胞转化的影响

Influence of growth and T lymphocytic transformation rate in rat fed with selenium-rich rice

目的 探讨富硒米的剂量与大鼠正常生长 (体重 )血常规和T淋巴细胞转化的影响 ,为富硒米用于保健食疗提供有意义的实验依据。方法 选用纯种SD大鼠 40只 ,随机分为高中低三个剂量组 ,分别给予富硒米和常规饲料喂养3 0d ,称重 ,取血做血常规和T淋巴细胞转化试验。结果 ①富硒米对大鼠正常生长 (体重 )无影响 ;②富硒米对大鼠血常规无影响 ;③富硒米能提高大鼠T淋巴细胞转化 ,中剂量组与对照组比较差异有显著性 (P <0 0 5 )。结论 富硒米能显著提高大鼠T淋巴细胞转化 ,对大鼠正常生长 (体重 )

Objective To have more information on healthy foods, the influence on growth and T lymphocytic transformation rate in rat fed with selenium(Se)-rich was studied. Methods 40 SD rats were randomly assigned into three groups in dosage of high, middle and low and fed with Se-rich or standard rat chow. Body weight, blood routine and T lymphocytic transformation rate were measured after 30 days. Results ① Se-rich rice had little effect on growth. ②Se-rich rice had little effect on blood routine.③Se-rich rice increased T lymphocytic transformation rate. There was significance difference between the middle dosage group and the control( P<0 05 ).Conclusion Se-rich rice increases T lymphocytic transformation rate in SD rats and has little effect on their normal growth and blood routine.
