thiazolyl

OBJECTIVE: To explore the effects of UA in different concentrations on human umbilical vein endothelial cells line ( ECV304), malondialdehyde ( MDA), nitric oxide ( NO) and 3-( 4,5-dimethyl thiazole-2)-2, 5-diphenyl thiazolyl blue ( MTT) in vitro.

目的：观察不同浓度的尿酸对体外培养的人脐静脉内皮细胞株（ECV304）丙二醛，一氧化氮及3-（4,5-二甲基噻唑-2）-2,5-二苯基四氮唑溴盐的影响。

Followed the prodrug fludarabine incubation, the cytotoxic effect, bystander effect and apoptosis induction of PNP/ fludarabine suicide gene system on BEL7402 cells were detected by methyl thiazolyl tetrazolium ( MTT) colorimetric method and Annexin V-FITC apoptosis detection kit, respectively.

分别应用四甲基偶氮唑蓝（MTT）比色法和Annexin V鄄FITC凋亡检测试剂盒检测PNP/fludarabine自杀基因系统对BEL7402细胞的细胞毒效应、旁观者效应和诱导凋亡作用。

Methods Methyl thiazolyl tetrazolium ( MTT) assay was used to measure its effects on the proliferation of SHG-44 cells cultured with different concentrations of Res for 6 h, 24 h, and 48 h.

方法四甲基偶氮唑蓝（MTT）比色法测量不同剂量的Res作用6h、24h和48h后对SHG-44胶质瘤细胞增殖的影响。
