ID50

Seven strains of endophytic fungi have their ID50 beyond 1000 , which constitute about 4.1 % of the total strains tested .

其中7个菌株的细胞毒ID50为1000以上，占总供测菌株的4.1%。

After a passage culture , one tenth of 24 hours ′ ID50 was added into the culture medium immediately , and cultured for 24 hours to investigate the rate of attached cells ;

细胞传代后立即加入5－FU24hID50浓度的1／10，作用24h后，计算细胞贴壁率；

Of all the isolates , there were 242 strains with antitumor activity ( ID50 50 ), including 136 strains of bacteria , 83 strains of actinomycetes and 23 strains of fungi .

通过抗肿瘤组合模型的筛选，共得到242株具有抗肿瘤活性的菌株（ID5050），其中细菌为136株，放线菌为83株，真菌为23株。

The ascitic liter was over 1 : 1000 by ELISA ; Seven strains of endophytic fungi have their ID50 beyond 1000 , which constitute about 4.1 % of the total strains tested .

ELISA法分析表明，腹水型单抗的效价均在1：1000以上；其中7个菌株的细胞毒ID50为1000以上，占总供测菌株的4.1%。

Ten chemotherapeutic agents were used in this test . From the dose effect curve of ovarian cancer cell lines to the agents with 10 different concentrations , we obtained the values of ID 50 and AUC at ID50 to evaluate the potency .

通过卵巢癌细胞株对化疗药物的量效关系曲线求出药物的ID50值及AUCatID50值来判断药效。

Results The ID50 of these extracting solution exposed to LEC for 24h and 72h were between 20.56mg/ml to 68.78mg / ml , and inhibition of water extracting-alcohol precipitating solution and percolation filtration solution was more strongly ( P < 0.05 );

结果五种水蛭提取液抑制LEC生长的24h、72hID（50）介于20.56mg／ml至68.78mg/ml之间，其中水提醇沉液、渗滤液具有更明显生长抑制作用（P＜0.05）；
