EFFECT OF OESTRADIOL MONOBENZOATE ON THE THE METABOLISM OF THE RAT ENDOMETRIUM

Abstract
The glucose uptake of isolated endometrium from castrated rats is increased by estradiol benzoate (50 y.%. subcut. in oil 48 hrs. before sacrifice.) The effect is seen anaerobically and aerobically. Glycogen breakdown and lactate formation were unaffected, O2 uptake was increased. 33% of the glucose utilized went to lactate when incubated aerobically, and 67% when anaerobic. The accelerated QO2 is accounted for by increased glucose utilization. The effect of estrogens on endometrial metabolism is believed to be chiefly by accelerating glucose utilization (i.e., hexokinase-catalyzed glucose phosphorylation by ATP.).
