[Effect of estrogen on glycogen synthesis in the rat uterus].

It is well known that an increase in glycogen content is one of the metabolic changes which estrogen induces in rat uterus, the target organ of the hormone . Although glycogen in the uterus has been considered to be an energy and nutritional source for the implan tation and growth of fertilized ovum, the mechanism of glycogen synthesis in the uterus and the biological significance of the elevation of glycogen level induced by estrogen have not been completely clarified yet. This paper deals with the mechanism of glycogen synthesis in rat uterus in the early
