title: Cytogenetic monitoring of a 24-hour effect of ethylmalonate platinum complex on human peripheral blood lymphocytes.
abstract: Analyses of mitotic activities and chromosome aberrations in lymphocytes of human peripheral blood have been utilized to evaluate 24-hour cytotoxic and genetic effect of various concentrations (0, 12, 60, 120, 240, 360 mumol l-1) of ethylmalonate platinum (EM-Pt) in vitro. EM-Pt was found to exert a mutagenic action, to have the character of a clastogenic agent and to affect primarily the G1-phase of the cellular cycle. Its activity may be affected by the concentration of the agent: a direct dependence was observed as regards occurrence of chromosome aberrations and an indirect one with regard to values of mitotic activity and cytotoxicity.
