摘要
应用单克隆抗体,流式细胞仪等方法,观察雷公藤多甙片水溶性及醇溶性成分对外周血淋巴细胞的作用。结果表明,雷公藤多甙片中水溶性成分及醇溶性成分在体外,对人外周血CD_4、CD_8的作用一致,使CD_4、CD_8阳性细胞增多(P<0.05),且二者都能增强PHA对CD_(25)表达的诱导作用(P<0.05),雷公藤多甙醇溶性成分为200μg/ml对静止期淋巴细胞有促分裂作用,而当其浓度达1mg/ml时,能抑制PHA对静止期淋巴细胞的促分裂作用。本文结果提示:雷公藤多甙中的水溶性成分在体外对淋巴细胞有免疫增强作用,而醇溶性成分在小剂量时有免疫促进作用,但大剂量时则为免疫抑制作用。
Abstract Monollonal antibody and flow cytometry were used to observe the effects of wat er-soluble and ethanol-soluble components in tabellae glucosidorum tripterygiitotorum(TGT)on peripheral blood lymphocytes(PBL).Results showed that there were similar effects of the 2 compo nents in TGT to PBL,the CD_4 and CD_8 positive cells all increased(P<0. 05).Meanwhile,both components enhanced the PHA-induction of CD_(25) expression. The ethanol component of TGT at 200 μg/ml had mitogenic effect on static phase lymphocytes. At 1mg/ml, it can inhibit the PHA mitogenesis effect on static lymphocytes. Our results showed that the water-soluble component of TGT has an immuno-enhancing effect on lymphoeytes in vitro,while the ethanol-soluble compo nent has an immuno-promoting effect at a low dose and has an immuno-suppressine effect at higher doses.Keywrods: tabellae glucosidorum tropterygiitotorum peripheral-blood lymphocyte
