Effect of sodium chloride on efficiency of cisplatinum dissolved in dimethyl sulfoxide: an in vitro study.

Cisplatinum (Cispt) is an anti-cancer drug with a low level of solubility. One of Cispt's solvents is dimethyl sulfoxide (DMSO) which can be substituted with chlorine of drug as Cispt's solvent. Applying such a solvent in biological studies is impossible due to intense reduction in activity.
