Nowacka, M. and Górski, J.: Metabolic response to starvation in late pregnant rats. II. Fetal response. Acta (physiol. Pol., 1988, 39 (5-6): 435-441. Effect of prolonged maternal fasting on the fetal liver and heart glycogen and triglyceride content and on concentration of glucose, urea, uric acid and alpha amino-nitrogen in the amniotic fluid has been studied in rats. The animals were divided into four groups: fed (control), fasted for one day (from 20 to 21 day of pregnancy), fasted for two days (from 19 to 21 day) and fasted for three days (from 18 to 21 day). Maternal fasting for two and three days resulted.in reduction in fetal growth. The fetal liver glycogen content was reduced already alter one day of fasting, stabilized after two days and then further decreased alter three days. The fetal heart glycogen content was reduced only after three days of fasting. The fetal liver triglyceride content increased gradually during the first two days of fasting and then stabilized. The content of triglycerides in the heart was elevated after two and three days of food deprivation. The amniotic fluid glucose concentration decreased after one day of fasting and then stabilized. Fasting did not effect the concentration of the nitrogenous compounds in the amniotic fluid. It is concluded that maternal fasting affects markedly metabolism of energy substrates stored in the fetal liver and the heart and the composition of the amniotic fluid.
