Sexual differences among duodenal glands of hamster.

This histochemical study was undertaken to determine whether sexual differences existed in the duodenal glands of hamster. Alcian blue staining and atomic absorption spectrophotometry (for copper content of the bound Alcian blue) showed the duodenal glands of males to contain about double the acid mucosubstance of the female glands. Periodic acid Schiff staining was stronger in the females over a larger portion of the gland than in males. It was concluded that sexual differences were evident in duodenal glands of hamster.
