【摘要】：目的:通過采用小鼠淋巴瘤細胞實驗微孔法,檢測二甲基亞砜(DMSO)的細胞毒性及遺傳毒性,探索其在檢測系統(tǒng)中的適宜濃度。方法:在非代謝活化(-S9)條件下,檢測美國Sigma和Tedi A兩家公司生產(chǎn)的2個批號DMSO,終濃度0.5%,1.0%,2.0%,4.0%處理L5178Y細胞3 h后產(chǎn)生的細胞毒性及誘發(fā)的TK基因突變頻率(MF)。結(jié)果:2個批號DMSO的細胞毒性均以1%濃度組為最低(20%),4%濃度組為最高(37%);1%濃度組誘發(fā)的MF與空白對照組相近,而其他3組則明顯增加(P0.05或0.01)。結(jié)論:當以DMSO為溶媒、采用L5178Y細胞進行MLA微孔法實驗時,采用1%作為檢測系統(tǒng)中受試物的體積比濃度較為適宜。
[Abstract]:Aim: to detect the cytotoxicity and genetic toxicity of dimethyl sulfoxide (DMSO) by micropore assay in mouse lymphoma cells and to explore the appropriate concentration of dimethyl sulfoxide (DMSO) in the detection system. Methods: under the condition of non-metabolic activation (-S9), the final concentration of two batches of DMSO, produced by Sigma and Tedi A in the United States was determined. The cytotoxicity of L5178Y cells and the induced TK gene mutation frequency (MF). Were detected after 3 h treatment of L5178Y cells with 1.0% or 2.0% DMSO,. Results: the cytotoxicity of the two batches of DMSO was the lowest (20%) in the 1% concentration group and the highest (37%) in the 4% concentration group (37%). The MF induced by the two batches of DMSO was similar to that of the blank control group, while the other three groups were significantly increased (P0.05 or 0.01). Conclusion: when L5178Y cells were used for MLA micropore assay with DMSO as solvent, the volume ratio of 1% was more suitable for the detection system.
