Glycoconjugates in the reproductive system of female rabbits in physiological estrogenic conditions

Glycopeptide fractions were isolated from the uteri and oviducts of female rabbits in physiological estrogenic conditions. Both from the uterus and the oviduct considerably heterogeneous heteropolysaccharides were extracted, formed by hexoses, hexosamines, fucose, sialic acid, uronic acids and sulphates. During the estrus stage an increase is found in all glucide components, except for sialic acid, which, on the contrary, decreases. This decrease has been explained on the basis of histochemical data obtained in previous researches.
