Histochemical localization of succinate dehydrogenase in the mouse submandibular gland during postnatal development.

The activity of succinate dehydrogenase (SDH) was examined histochemically in the parenchyma of murine submandibular gland (SMG) during postnatal development on light-microscopical level. In this study, SDH appears as a good marker of differentiating and mature striated ducts of both sexes and convoluted granular tubules of males. Enzyme activity in glandular parenchyma increased from the 1st day to the 7th week of postnatal life. Definitive enzymatic pattern was seen in the gland aged 7 weeks. Histochemical differences between male and female SMG of mouse were noted.
