【摘要】 为了解人胎肝细胞 (FL C)对受体免疫系统及其功能的影响 ,作者采用 BAL B/ c小鼠进行了 FL C腹腔注射实验研究。实验分为空白对照和 FL C高、中、低剂量 (1 2 5× 1 0 5 ,2 5× 1 0 5 ,5× 1 0 5 胎肝细胞 /日 )组。结果显示 :FL C可增加小鼠胸腺脏器系数、外周血 T淋巴细胞数和淋巴细胞总数、脾细胞总数、抗体生成细胞数、淋巴细胞转化百分率和刺激指数 ,以及腹腔巨噬细胞吞噬作用 ,还可以影响 NK细胞活性。上述结果提示 ,人 FL C可增强小鼠非特异性免疫、体液免疫和细胞免疫功能 ,但对小鼠脾脏脏器系数无明显影响 ,也未见引起迟发型变态反应更多还原

【Abstract】 This study sought to better understand the effects of human fetal liver cells(FLC) on immunity. FLC were injected into BALB/c mice intraperitoneally. The design included four groups: negative control and three dose(125×10 5,25×10 5,5×10 5 FLC/day)groups. The results showed that FLC increased the thymus visceral coefficient, numbers of T lymphocytes(TLC) and lymphocytes(LC) in blood, total number of spleen cells, the number of plaque forming cells(PFC) of spleen, the rate(%) of transformation and stimulus index of TLC of spleen, and the function of macrophages. FLC also effected the function of natural killer cells(NK cells) of BALB/c mice. The findings suggest that human FLC can strengthen the nonspecific immunity, humoral immunity and cellular immunity in mice. In this study, however, no effect of FLC on spleen visceral coefficient was noticed, and no sign of delayed type allergy was observed.更多还原
