中华猕猴桃根是一种中药材。本文报道了从它的根中提取的多糖复合物(简称 ACPS)对小鼠免疫系统的调节作用。小鼠每日腹腔注射 ACPS,1~2周后分别测定免疫功能。结果:(1)ACPS 能明显促进天然杀伤(NK)细胞对 YAC-1淋巴瘤细胞的细胞毒作用;(2)能加强巨噬细胞的吞噬功能;(3)能明显增加特异花结形成细胞(SRFC)数,但对抗体形成细胞(PFC)无任何影响;(4)能有效地恢复被环磷酰胺抑制了的迟发超敏(DTH)反应。上述结果表明 ACPS 是一种有效的免疫调节剂。这在机体抗病毒抗肿瘤中或许有重要意义。 相似文献

A new polysaccharide compound (ACPS-R) has recently been isolated from the root of Actinidia Chinensis Planch. When given inttaperitoneally to the transplantable tumor bearing mice at dose of 75-125 mg/kg, the tumor inhibition rate was more than 88.8% in Ehrilich ascitic cancer (EAC) or ascitic from of hepatoma (HepA) and more than 49.6% in solid hepatoma (HepS). The treatment effect of ACPS-R on EAC at dose of 80-100 mg kg and 125 mg/kg were comparable to that of cyclophosphamide at dose of 15 mg/kg and 22.5 mg/kg, respectively. ACPS-R could also prolong the life of EAC- or P388-bearing mice, and increase the percentage of EAC-free mice. In addition, when ACPS-R was used in combination with 5-Fu, the antitumor effect was enhanced as compared with 5-Fu alone. A marked increase in cAMP levels end cAMP cGMP ratio of spleen of EAC-bearing mice were observed after treatment of ACPS-R. The increase of both para meters nearly reached the normal levels of healthy mice. The increases of cAMP, cAMP cGMP and tumo 相似文献

三根冲剂(虎杖根、水杨梅根、屯梨根)是我们临床长期用于治疗消化道癌肿的一张经验方,为探讨其抗癌作用机制我们应用原子吸收分光光度仪测定了单药及制剂的硒(Se)、铜(Cu)、锌(Zn)的含量,结果发现该制剂的硒含量为0.018 mg/kg、锌为24.44 mg/kg、铜为11.67 mg/kg。其抗肿瘤作用可能与补充一定数量的硒,达到增强免疫功能,提高血清锌水平,改变铜/锌比值等机制有关。 相似文献
