Effects of AET and MEA treatment of mice on the first day of pregnancy

Porton female mice were injected intraperitoneally with 2-aminoethylisothiouronium bromide hydrobromide (AET) or cysteamine hydrochloride (MEA) in a dose of 40 mg/kg of body weight on the first day of pregnancy. On the last, nineteenth, day of gestation, taking into consideration females in whose uterus live fetuses were observed, the increase in their body weight throughout pregnancy, the number of fetuses in the uterus, the body weight of fetuses, and placental weight were found smaller in mice treated with AET or MEA, than in control ones. Among the injected compounds, AET appeared to be less toxic than MEA.
