2、研究發(fā)現(xiàn)在不同藥物(順鉑、長春新堿、卡鉑、紫杉醇、5.Fu)作用下,CNE2/cDDP較CNE2的Ic。值及耐藥指數(shù)均有明顯的增加,CNE2/cDDP細(xì)胞對(duì)順鉑的耐藥性最強(qiáng),增加到200.6倍,對(duì)5.Fu的耐藥性最差,增加到2.8倍;耐藥細(xì)胞株CNE2/cDDP較非耐藥細(xì)胞株CNE2生長速度減慢,其細(xì)胞倍增時(shí)間由18h增加到24h;CNE2/cDDP細(xì)胞體積較CNE2為小,常呈克隆聚集現(xiàn)象。結(jié)論CNE2/cDDP具有多藥耐藥性,是一個(gè)理想的用于鼻咽癌的多藥耐藥研究的細(xì)胞系。關(guān)鍵詞:順鉑;鼻咽癌;多藥耐藥性;細(xì)胞系(CNE2/cDDP)中圖分類號(hào)
