摘要: 目的: 研究拟康氏木霉胞外多糖体内外抗肿瘤活性。方法: 体外采用MTT法检测拟康氏木霉胞外多糖对人白血病细胞HL-60抑制作用;体内试验是将昆明种小鼠接种S180实体瘤后随机分组,灌胃50、100、200 mg·kg-1·d-1剂量的多糖,以生理盐水和环磷酰胺为空白对照组和阳性对照组。检测受试药物对小鼠S180实体瘤的抑制作用,计算小鼠的相对生长率及其免疫器官指数。结果: 经MTT法检测,拟康氏木霉胞外多糖 0.2~1.0 mg/mL 五个浓度对HL-60细胞均有不同程度的抑制作用,并呈现出剂量相关性,其中 1.0 mg/mL 多糖浓度在 72 h 的抑制率可达 40.36%。而该多糖低、中、高三个剂量组均能明显减少S180小鼠的瘤重,其中高、中剂量组能明显提高小鼠的胸腺指数和脾指数(P<0.05,P<0.01),但与空白对照组比较,三个给药组对小鼠的相对生长情况并无明显影响。结论: 拟康氏木霉胞外多糖具有一定的抗肿瘤作用。

Abstract: AIM: To study antitumor effect of extracellular polysaccharides from Trichoderma pseudokoningii.METHODS: In vitro, we studied the antitumor activity of TPeps on human leukemia HL-60 cells with MTT, and in vivo, TPeps were intragastrically given to mice with S180 solid tumor at the dose of 50, 100 and 200 mg·kg-1·d-1. Normal sodium and cyclophosphamide were taken as blank control and positive control respectively. The tumor weight, spleen index, thymus index and the relative growth rate were measured.RESULTS: TPeps could significantly inhibit HL-60 cells proliferation in a time and concentration dependent manner. Meanwhile, compared with control TPeps three dose groups significantly decreased the weight of tumor, increased the spleen index and thymus index(P<0.05,P<0.01). However, TPeps had no discernible effect on the relative growth rate.CONCLUSION: TPeps have a certain amount of anti-tumor action.
