为观察香菇多糖脂质体(LiposomescontainingLentinan,LipLNT)与低剂量IL2协同体内扩增,激活腹腔巨噬细胞(Peritonealmacrophage,PM)杀瘤活性。体内诱导Balb/c小鼠2d后,收集计数腹腔渗出细胞(Peritonealexudatecels,PEC)及PM,监测PM细胞毒及TNF活性,并于香菇多糖(Lentian,LNT)进行了比较。结果:LipLNT,LNT与IL2联合可协同使PEC体内大量扩增,PM细胞毒活性及TNF分泌显著增加,其中LipLNT较LNT最小有效剂量减小5倍,最适剂量减少4倍,而PM杀瘤活性提高30%,且以靶向扩增PM为主,达72%。结论:LipLNT较LNT生物活性显著提高,LipLNT与小剂量IL2联合使PM、PEC体内大量增殖,PM杀瘤活性增强并促进TNF生成。
In order to observe the synergistic in vivo expansion of LiposomescontainingLentinan (LipLNT) and lowdose IL2, activation of peritoneal macrophage (PM) was performed. Balb / c mice were induced in vivo for 2 days. Peritonealexudatecels (PEC) and PM ¢ ñ were collected and counted for cytotoxicity and TNF activity in PM ¢ ñ cells. Lenti, LNT were compared. Results: LipLNT, LNT and IL2 combined can make a large number of PEC in vivo expansion, PM cytotoxic activity and TNF secretion increased significantly, which LipLNT LNT minimum effective dose was reduced 5 times, the optimum dose decreased 4 times, while the PM tumor killing activity increased by 30%, and target-based amplification of PM , 72%. CONCLUSION: LipLNT has significantly higher biological activity than LNT. Combined with LipLNT and lowdose IL2, PM and PEC proliferate in large quantities, and PM tumor killing activity is enhanced and TNF production is promoted.
