Alterations in the rate of fetal and placental development as a consequence of early maternal protein/calorie restriction.

摘要: The in utero growth rates have been determined for the body, brain, and placenta rat. accumulation of cell number (DNA content) protein content cerebrum were investigated during normal development. When rats exposed to a severe reduction protein/calorie intake first 10 days pregnancy fetal compared those control animals, highly significant differences observed. Pregnant rats, which restricted their early part pregnancy, significantly prolonged gestation time. this increase time is taken into consideration offspring are at natural birth, data presented demonstrate possibility catch up growth. variations, development within same litter across litters, considerable plasticity utero.
