Toxic effects of selenodiglutathione on pregnant mice

Junzo Yonemoto; Tetsuro Hongo; Tsuguyoshi Suzuki; Akira Naganuma; Nobumasa Imura

A single dose of selenodiglutathione (GSSeSG) or sodium selenite (SS) was injected i.v. into pregnant CD-1 mice on day 12 of gestation at dosages varying from 16.4-32.0 mumol/kg body weight. Dose-dependent elevation of maternal death rates was observed for both treatments, and the slope of the dose-response curve was significantly steeper following GSSeSG treatment. However, fetotoxic effects were not different between the treatments.
