【中文摘要】 采用體外腫瘤細胞株(小鼠白血病細胞株L1210、人乳腺癌細胞株MCF-7和人腸腺癌細胞株SW620)的增殖抑制試驗?zāi)Ｐ秃涂共《?流感甲型病毒和皰疹病毒)的篩選模型,對3個金耳(Tremella aurantialba)菌株菌絲體醇提物活性進行比較研究。抗腫瘤試驗結(jié)果表明,3種提取物材料在高濃度(200μg/mL)時,對3個供試腫瘤細胞株的細胞增殖均有明顯的抑制作用,其中以YK的抑制活性最高(對L1210、SW620和MCF-7的抑制率分別為89.4%,75.0%和64.1%);在中濃度(50μg/mL)時,均表現(xiàn)出一定的抑制作用;而在低濃度(10μg/mL)時,則均無明顯的抑制作用?？沽鞲屑仔筒《竞涂拱捳畈《驹囼灲Y(jié)果表明,只有YK對流感甲型病毒表現(xiàn)有抗病毒活性,但此活性較弱。
【英文摘要】 Ethanolic extracts of mycelia from three strains of Tremella aurantialba were tested for in vitro tumor cell inhibitory effects using murine leukemia(L1210),human intestinal adenocarcinoma(SW620) and human breast cancer(MCF-7) cell lines,and for antiviral activity using A-FLU,HSV-Ⅰand HSV-Ⅱviral models.Significant inhibition of tumor cell proliferation by extracts of all three mycelial samples was observed at 200 μg/mL concentration.Highest levels of L1210,SW620 and MCF-7 cell inhibition,observed with extracts of strain YK,were 89.4%,75.0% and 64.1%,respectively.Lower inhibitory effects were recorded at 50 μg/mL concentrations,and only weak inhibition was observed when cell lines were treated with extract concentrations of 10 μg/mL.Antiviral activity,in the form of weak effects against A-FLU virus,was observed only in the case of ethanolic extracts of strain YK mycelium.
