[VDT pulse magnetic field enhances teratogenic effect of ara-c in mice]

Impregnated NIH mice were irradiated 4 hrs daily on days 16th-17th of gestation with 15.6 kHz pulse magnetic field at 40 microT peak to peak. Significant enhancement of ara-c induced teratogenic potency by the magnetic field can be observed. The incidence of harelip fetuses bearing harelip and/or cleft palate was significantly higher in the combined exposure group, in which mice were exposed to the magnetic field and given an intraperitoneal injection of ara-c on the 9th day of gestation, than that of mice treated with ara-c alone.
