摘要
90只雄性BALB/c小鼠随机分为6组,分别为健康对照组、模型对照组、阳性对照组和3个高、中、低蛹虫草多糖(CMP)剂量组。3个CMP组和模型对照组分别腹腔注射80mg/(kg·d)环磷酰胺,连续3d,然后3个CMP组分别灌胃给予17.5、35、70mg/kg CMP;健康对照组和模型对照组给予生理盐水;阳性对照组灌胃给予70mg/kg CMP,持续18d,于最后一次给药24h后,每组抽取3只小鼠用碳粒廓清试验检测巨噬细胞的吞噬指数;取3只小鼠用MTT法测定淋巴细胞增殖;其余小鼠称重后颈椎脱臼处死,采集内脏并称重,计算脾脏指数、胸腺指数。结果显示,3个CMP组以剂量依赖的方式增加小鼠的脾脏指数、胸腺指数、脾淋巴细胞增殖和巨噬细胞的吞噬指数,高剂量组的吞噬活性恢复到正常水平。结果表明,CMP可逆转环磷酰胺诱导的免疫器官萎缩,增强免疫抑制小鼠的细胞免疫和巨噬细胞功能。
