  • Title: The regulatory effect of estrogens on fetal growth. IV. Brain development in growth accelerated fetuses in rabbits.
    Author: Abdul-Karim RW, Pavy M, Beydoun SN, Haviland ME.
    Journal: Biol Neonate; 1976; 29(1-2):89-95. PubMed ID: 945079.
    Abstract:
    Brain weights and DNA, RNA, and total protein concentrations were determined on 31-day-old fetuses whose growth had been accelerated incidental to estrogen deficiency following maternal oophorectomy. Compared to controls, there were no differences in the DNA, RNA, or total protein concentrations, although the mean brain weight was increased. The higher mean brain weight in the growth accelerated fetuses was related to the increased mean fetal weight, and did not represent an independent response to the estrogen deficiency. A comparison of the influence of fetal weight versus gestational age on the weight of the fetal brain shows that gestational age exerts an effect apart from that of fetal weight.
