title: Quantitative morphology and carbohydrate histochemistry of the mouse submandibular gland following prepubertal castration.
abstract: The endocrinologic basis for morphological and biochemical sex differences in the mouse submandibular gland have not been clarified. Previous studies have emphasized the maintenance of glandular differences in adult animals, rather than considering the factors responsible for their developmental etiology. Male CD-1 mice were castrated at intervals between 10 and 50 days of age and killed at 100 days. The quantitative development of granular tubules and the carbohydrate histochemistry of the submandibular glands were compared to untreated males and females. The area of granular tubules increased with age at castration. Nested analysis of variance indicated significant differences among treatments and among sections within individual glands. No group of castrated males had a greater development of tubules than untreated females. Carbohydrate histochemistry demonstrated an increase in carboxylated mucosubstances in the acinar cells and granular tubule cells of castrated animals.
