Hypophysis effect on the topographical distribution of toad oviduct mucoprotein components.
In the present work the effects of the hypophysis hormones on oviduct mucoprotein components distribution patterns were studied. Remarkable changes after treating the toad with hypophysis injections were apparent. The distribution pattern for hexose, sialic acid, hexosamine and phosphate from 18 hours hypophysis treated toads were found to be identical with those obtained from preovulatory period animals. On the other hand, the levels for mucoprotein components from hypophysis treated animals were found to be approximately one-half or more higher than those obtained from postovulatory period toads. Otherwise, hypophysis treatment of the toads in preovulatory period had not effect on the levels and distribution patterns of mucoprotein components. These results suggest that hypophysis hormones are involved in the increase of the oviduct secretory activity.
