[Effect of sex hormone on the respiration and glycolysis processes in female rabbit placenta tissue].

The respiratory and glycolytic activity of the female-rabbits placenta tissue on the 11th and 30th days of pregnancy was studied as affected by progesterone, estrone and chorionic gonadotrophin. The tissue respiration of the placenta at the end of pregnancy is established to be more sensitive to administration of the hormones under study than at the beginning of pregnancy. The glycolytic activity of the placenta tissue under the effect of hormones is decreased both at the beginning and at the end of pregnancy. Only anaerobic glycolysis is an exception when progesterone is administered at the beginning of pregnancy.
