Abstract
The maternal obesity was studied in mice.
Changes in body weight, fat weight/body weight, daily food intake, liver glycogen, blood glucose, blood proteins and tyrosine aminotransferase activity were examined during pregnancy, lactation and weaning (recovery) periods.
The results were as follows;
1) The maternal obesity was observed after weaning in lactated mice and after pregnancy in nonlactated mice. The extent of obesity was higher in lactated mice than in nonlactated mice.
2) The increase of daily food intake was not observed at appearance of the obesity.
3) The activity of tysosine aminotransferase, that is, the level of blood glucocorticoid, increased during pregnancy and lactation was decreased immediately after weaning. Then followed decreased of liver glycogen and blood glucose, and an increase of blood proteins.
