title: Glycosidases in the rat uterus during the oestrus cycle.
abstract: Seven acid glycosidases activities have been measured in normal rat uterus during the oestrus cycle. It has been observed that alpha-fucosidase, alpha-mannosidase, beta-galactosidase, alpha-galactosidase, aryl sulfatase, acid phosphatase and hexosaminidase activities changed cyclically during the oestrus cycle. From onward oestrus to metaoestrus the enzyme activities are in their highest level, but then decline slightly towards the resting one, as the cycle progresses. It is possible that changes in glycosidases content bear a lysosomal relationship, since it is known the increase in the lysosome content of the uterus during the oestrus and metaoestrus. The increased enzyme content could be related to uterus glycoproteins secretion and degradation during the normal oestrus cycle.
