Unable to load video. Haemodynamic changes in the second half of pregnancy: The continuation of maternal malnutrition up to the 21st day was associated with decreased fetal weight and increased incidence of intrauterine growth retardation even though placental weight was maintained and glycogen stores evolved normally.

On the 21st day there was a clear occurrence of retarded intrauterine growth in the young from malnourished mothers Figure 3. The action of severe maternal hyperglycemia depletes the fetal pancreas, which loses the ability to produce insulin at fisiopatoloyia end of pregnancy. The thickness of the placental exchange surface decreased from the 18th to the 21st day of pregnancy in all groups studied, but the placentas did not differ in terms of quantity of cytotrophoblastic cells.

Placental glycogen stores were normal on the 18th day and decreased by the fisiopatilogia day of pregnancy in the control groups and in the groups with dietary restriction introduced on the 1st day of pregnancy.

In the pancreas of newborn rats with severe diabetes the islets are large but have no insulin-positive cells and therefore their insulin production is depleted.

This leads to the removal of glycogen deposited in the placenta which, converted into energy, increases the weight of newborn rats. J Ped ;46 1: Dietary restriction after the 3rd day of pregnancy led to low placental glycogen concentrations on the 18th day and disappearance on the 21st day. Histochemical analysis was performed by the periodic acid Schiff PAS reaction for the identification of glycogen deposits on the placental membrane on 18th and 21st days of pregnancy.

Placental glycogen stores also decreased after the 18th day in the control groups and in the groups submitted to dietary restriction from the 1st day of pregnancy.
