摘要:

目的: 研究9种不同的有机溶剂不同体积分数下对体外培养的CHL细胞的毒性作用。方法:采用MTT法,对0.1% 、0.3%、1%、3%和10%体积分数下DMSO、二氧六环、乙腈、丙酮、四氢呋喃、甘油、冰醋酸、甲醇和乙醇对CHL细胞的抑制率进行测定,计算出细胞抑制率达20%时各溶剂的体积分数。结果:DMSO、二氧六环、乙腈、丙酮、四氢呋喃、甘油、冰醋酸、甲醇和乙醇对CHL细胞抑制率达20%时,体积分数分别为1.0%、0.2%、1.5%、5.4%、0.2%、3.2%、0.000 07%、1.7%和2.1%。结论:在进行染色体畸变试验时,应充分了解受试物特点,并在此基础上根据溶剂的特点及毒性选择合适的溶剂。

Abstract:

 OBJECTIVE: To explore the cytotoxic effects of 9 different solvents with different volume fractions on CHL cells in vitro. METHODSMTT was used to study the inhibition rates of different solvents on CHL cells at 0.1%,0.3%,1%,3%,10% volume fractions,and thus to calculate the volume fraction of each solvent causing cell inhibition rate of 20%. RESULTSWhen the inhibition rates of DMSO,diethylene dioxide,acetonitrile, acetone, tetrahydrofuran,glycerine,acetic acid,methanol and ethanol on CHL cells reached 20%,the volume fractions were 1.0%,0.2%,1.5%,5.4%,0.2%,3.2%,0.000 07%,1.7% and 2.1%,respectively. CONCLUSION:When performing chromosome aberration test,one should first fully understand the characteristics of the test substance,on this basis, to select the appropriate solvent according to their characteristics and toxicities.
