This study examined the effect of pyrimethamine (PYR) on sister chromatid exchanges (SCEs) in human lymphocytes. PYR is a folic acid antagonist used for the treatment of malaria and toxoplasmosis. PYR was added to peripheral blood lymphocyte cultures at three different doses: 0.05, 0.1, and 0.2 mg/m

The induction and persistence of sister chromatid exchanges (SCEs) were studied in peripheral blood and spleen lymphocytes of mice given a single i.p. injection of ethylnitrosourea (ENU) of 100,350, or 600 pMoles ENU/kg. SCE frequencies were measured on days 1, 3, 5 , and 7, and at seven additional
