EFFECT OF OESTROGENS ON THE GLYCOGEN CONTENT OF THE RAT UTERUS

Abstract

The significance of glycogen breakdown in energy transformations during muscle contraction is well established. In uterine muscle contraction its significance may be even greater than in skeletal muscle on account of the low content of ATP and phosphocreatine (Walaas & Walaas, 1950). The dependence of uterine contractility on steroid hormones suggests the determination of energy substances under different hormonal influences. The present work has been concerned with the determination of the glycogen content of rat uterus after the administration of oestrogens.
