[求助] 大神!翻译一段英文,有重谢!!!

All tested compounds were dissolved in DMSO (1-100µM solution ) and subsequently diluted in the culture medium before treatment of the cultured cells . Tested cells were plated in 96-well plates at a density 2×103cells /well /100mL of the proper culture me dium and treated with the compounds at 1-10 0 µM for 72 h. In parallel , the cells treated with 0 .1 % DMSO served as control . An MTT [3-(4,5-dime thylthiazol-2-yl)-2,5-diphenyl tetrazolium-bromide ] assay (Roche Molecular Biochemicals , Cat. No.11465007001) was performed 4h later according to the instructions provided by Roche. This assay was based on the cellular cleavage of MTT into formazane which is soluble in cell culture medium. Any absorbance caused by formazan was measured at595 nm with a microplate reader ( BIO-RAD , model 680 ), which is directly proportional to the number of living cells in culture. Three types of cells were used in these assays , PC3 (prostate cancer) ,BGC 823 (human gastric cancer ) and Bcap37 ( breast cancer) cell lines , provided by ATCC and cultivate din RPMI 1640 ( for PC3,BGC823 and Bcap37) supplemented with 10% fetal bovine serum. Tissue culture reagents were obtained from Gibco BRL [14] .The experiment was performed in triplicate. The percentage cytotoxicity was calculated using the formula.

所有用于实验的化合物溶解于DMSO中,在作用细胞前用培养液稀释。将细胞种植在96孔板,密度为2×103细胞/孔/100uL,加入1-100μM化合物,作用72小时处理。同时,以加0.1% DMSO的作为对照组。4h后,依照试剂说明进行MTT(3-4,5-二甲基噻唑-2,5-二苯基四氮唑溴盐,噻唑蓝)实验(罗氏公司,试剂号11465007001)。本实验基于活细胞可以将MTT分解为可溶性的甲瓒。甲瓒的吸光度可以用酶标仪(BIO-RAD,680型)在595nm下测得,它同培养的活细胞的数目成正比。三种细胞被用于此实验,PC3(前列腺癌),BGC823(人胃癌)和Bcap37(乳腺癌)细胞系,细胞株由ATCC(美国菌种保存中心)提供,以含有10%胎牛血清的RPMI 1640培养液培养。组织培养试剂购于Gibco BRL公司[14],每组实验有三孵孔。利用下列公式计算细胞毒性的百分率。

楼上的翻译不错,有个别瑕疵。

试验所用化合物均溶解于DMSO,并在处理细胞前以培养液稀释。试验细胞置于96孔板,密度为2×103细胞/孔/100uL,以1-100μM的化合物处理72小时。同时,以0.1% DMSO为对照。4h后,依照罗氏公司的试剂说明进行MTT(3-4,5-二甲基噻唑-2,5-二苯基四氮唑溴盐,噻唑蓝)测定(罗氏公司,试剂号11465007001)。MTT测定原理基于MTT被细胞分解为细胞培养基中可溶的甲瓒。甲瓒的吸光度可以用酶标仪(BIO-RAD,680型)在595nm下测得,它和培养中的活细胞数成正比。三种细胞被用于该试验,即PC3(前列腺癌)、BGC823(人胃癌)和Bcap37(乳腺癌)细胞系。这些细胞株由ATCC(美国菌种保存中心)提供,以含有10%胎牛血清的RPMI 1640培养液培养。组织培养试剂购于Gibco BRL公司[14],每组实验设3次重复。利用以下公式计算细胞毒性的百分率。
细胞毒性% =100 x [ (对照吸光值-空白吸光值)-(测试吸光值-空白吸光值)]/(对照吸光值-空白吸光值)
