Abstract
OBJECTIVE: To research the effects of organic solvents on proliferation inhibition of Hela cells line. METHODS: The apoptosis of Hela cells induced by ethanol and dimethylsulfoxide (DMSO) were studied to analyse the error analyse from background organic solvents. The apoptosis of Hela cells induced by ethanol, DMSO and the combination of these two organic solvents with different concentrations were observed by MTT test and Giemsa staining. RESULTS: The Hela cells proliferation were significantly inhibited by ethanol with the concentrations ranged from 30% to 100%, and DMSO with the concentrations ranged from 50% to 100% (P < 0.01). There were no significantly difference between the two combination of ethanol 40% + DMSO 60%, ethanol 30% + DMSO 70% and control group (P > 0. 05) respectively. CONCLUSION: The cells proliferation were inhibited by organic solvents itself and were in a time and dose dependent. The background experimental error can be reduced remarkably by choosing the two organic solvents combination of ethanol and DMSO.
