【摘要】 <正> 近十余年来国内外已注意到一些天然来源的中草药和植物多糖有非特异性免疫刺激作用及抗肿瘤效应,临床实验也表明某些中草药和植物多糖与促进机体免疫功能和抗肿瘤关系密切。我们前文已报道,新鱼腥草素对小白鼠移植型肝癌及艾氏腹水癌有抑制作用并可升高癌细胞内cAMP水平。中山医科大学化学更多还原

【Abstract】 Our experiments have shown that New-Keto aldehyde and Neohouttuyninum could inhibit the growth of CNE-i, CNE-2, and Hela tumor cells in vitro, they also inhibited the activity of cAMP-PDE. Both the inhibitions are strengthened with the increasing of their medical doses.These resultes indicated that the inhibitory effects of New-Keto aldehyde and Neo-houttuynimum on the cancer cells in vitro may be related to inhibition of the activity of cAMP-PDE mudulating the level of cAMP in the tumor cells.更多还原
