ANAEROBIC GLYCOLYSIS IN RAT OVARIAN TISSUES DURING PREGNANCY AND LACTATION1

Abstract
The anaerobic glycolysis of the lutein tissue and of the remaining ovarian tissue was detd. during diestrus, pregnancy and lactation in the rat. The glycolytic activity of the corpora of pregnancy increases sharply from the 2d day of diestrus to the 4th day of pregnancy and remains essentially unchanged throughout pregnancy. There is a significant drop in the activity of this tissue from day 20 of pregnancy to the 4th day of lactation. In the corpora of lactation, there is no significant change in activity. The changes in the glycolytic activity of lutein tissue are discussed in relation to the previously detd. changes in succinic and malic dehydro-genases of this tissue.
