Abstract
The distribution of 54Mn in various organs of pregnant rats and of their 19-day-old fetuses and in non-pregnant female rats of various ages has been studied 18 h after an i.v. injection of 54MnCl2. The results indicate that early neonates are more susceptible to manganese (Mn) than the growing rats. The localization of 54Mn in liver and brain of the embryo was highly significant.
