title: Cyclical changes in the carbohydrate composition of dog endometrium.
abstract: In the first part of prooestrus glucuronic acid could not be detected, but small amounts of glucose, fructose, inositol and sorbitol were found. When progesterone was formed a small amount of glucuronic acid could be observed and sorbitol had disappeared. During the first weeks of metoestrus the amounts of fructose and glucose increased gradually, but those of glucuronic acid remained low. When more progesterone and pregnanedione were found in the endometrium the amounts of glucuronic acid began to increase and the highest values were reached in anoestrus. During the last days of anoestrus a sudden change in the carbohydrate composition of the endometrium occurred: glucuronic acid and fructose could no longer be detected, the amounts of glucose and inositol decreased and sorbitol was found. These findings show that next to the cyclical ovarian events, there is a cyclical change in te carbohydrate composition of dog endometrium.
