Characterization of mouse salivary glands by water content and type

The thermoanalytical analysis was applied to samples of sublingual, submandibular and parotid glands from sexually mature mice of both sexes. Findings indicated that the three salivary glands show a behaviour of water release characteristic for each type of gland. Derivative thermogravimetry curves concerned with the sublingual and parotid glands belonging to male and female subjects exhibited overlapped results. As regards submandibular gland, instead, some differences emerged between subjects of different sex. Water content and types in sublingual, submandibular and parotid glands were discussed and related to the different morphological expression, histochemical reactivity and chemical composition of these organ tissues.
