摘要
目的研究胎盘冻干粉对小鼠延缓衰老的作用。方法将2月龄雌性小鼠随机分为5组:空白组、衰老组、阳性组、胎盘粉低剂量组和高剂量组。除空白组外,其余各组均采用皮卞注射相同剂量D—半乳糖42 d建立小鼠衰老模型,同时各组分别灌胃相应的药物,最后检测小鼠机体内免疫力及生理调控相关指标。结果胎盘粉2个剂量组小鼠的胸腺指数和脾脏指数显著高于衰老组(P<0,05),大脑中的MDA含量显著低于衰老组(P<0.05),外周血中的CD4和(CD8细胞比例、血清中雌性激素(P和E 2)、免疫球蛋白(lgG)以及造血因子(EPO、G—CSF和M-CSF)的含量均显著高于衰老组(P<0.05)。结论胎盘冻干粉能够通过提高机体免疫力、改善生理调控来达到延缓衰老的作用。
Objective To investigate Anti-aging function of Placenta freeze-dried powder on mice. Method 2 month old female-KM mice were divided into five groups:normal control group, aging model group, positive control group, placenta freeze-dried powder low dose group and high dose group. Except normal control group,the rest of groups were treated with method of subcutaneous continuous injection of D-galactose for 42 days in order to establish mice aging model. Meanwhile, the corresponding drugs, via intragastric administration, were ingested by different treated groups and observe the change of immunity and physiological regulation related in mice. Results Compared with aging model group, thymus index and spleen index in placenta freeze-dried powder low dose group and high dose group increased obviously (P<0.05), content of MDA in brain decreased significantly (P<0.05), proportion of CD 4 and CD 8 lymphocyte in total lymphocyte, female hormone(P and E 2), IgG and haemopoietic factor in peripheral blood increased remarkably. Conclusion Placenta freeze-dried powder could slow the aging process on mice via immunity enhancement and improving physical regulation.
