Weight and radioactivity of the organs of progeny after 5-HT and/or Na2H32PO4 treatment of pregnant mice.

: In 30-day-old offspring of mice treated with 5-HT and/or Na2H32PO4, there was a decrease in the fresh weight of the organs, being more noticeable in males than in females. In relation to a group injected with Na2H32PO4 and that to which both 5-HT and Na2H32PO4 were administered, a greater fresh weight of the organs in mice treated with 5-HT only was found. No differences in the radioactivity of 32P in the organs of 30-day-old offspring between the group of mice treated with Na2H32PO4 only and that injected with both 5-HT and Na2H32PO4, were observed.
