中文摘要: |
本实验用MTT比色分析法研究了茯苓多糖(PPS)、刺五加多糖(ASPS)、银耳多糖(TF)和香菇多糖(Lentinan)4种植物多糖对体外培养的小鼠腹水型肉瘤S180细胞和人慢性骨髓性白血病K562细胞增殖的影响,结果证实PPS、ASPS在体外具有直接抗肿瘤作用。PPS对两种肿瘤细胞的半数有效抑制浓度(IC50)均为1.5mg/ml,ASPS对S180和K562细胞的IC50分别为0.38mg/ml和0.28mg/ml;TF和Lentinan对两种细胞的增殖无抑制作用。本实验同时检测了PPS、ASPS作用于S180细胞24h后,细胞膜唾液酸(SA)、磷脂(Pl)、胆固醇(Ch)含量的变化,发现除Ch及Ch/Pl比值无明显变化外,SA升高(P<0.05)、Pl减少(P<0.05),提示PPS、ASPS的抗肿瘤作用可能与之有关。 |
英文摘要: |
The four kinds of plant polysaccharides,i.e.,pachyman polysaccharides(PPS),Acanthopanax senticosus polysaccharides(ASPS) ,polysaccharides of tremella fuciformis(TF) and lentinan,have obviously inhibitory action against the animal tumor growth and have been applied to the treatment of cancer. The mechanism was that they could enhance the body immune function, but whether the tumor cells were killed is not clear. In this paper, the effects of the four plant polysaccharides on cell proliferation in mice sarcoma (ascitic type) S180 and human chronic myelogenous leukemia K562 cells were studied with MTT chromometry. Tt was found That TF and lentinan had no effect on both cell line,but PPS and ASPS could obviously inhibit the proliferation of them,the IC50 of PPS was 1.5mg/ml in both cell line,that of ASPS was 0.38 mg/ml(S180 cells) and 0.28mg/ml (K562 cells)respectively.This result indicated that the PPS and ASPS were able to kill the tumor cell directly.To investigate the mechanism of antitumor action of PPS and ASPS, the sialic acid (SA),phospholipid(PI) and cholesterol (Ch) contents of S180 cell membrane were examined after the PPS or ASPS application for 24 hours. No significant changes were observed for the Ch and Ch/pl ratio,the amount of SA increased and that of PI lowered respectively(P<0.05).The results suggested that the antitumor action of PPS and ASPS not only related to the action of enhancing the body immune function but also related to the changes of cell membrane. |
