Abstract

The current study aimed to determined the histological and histochemical structure of major salivary glands taken from six mature female and male guinea pig captured locally in Al-Samawa city (Province of Al-Muthanna, Iraq) after euthanized of animals, the major salivary glands fixed in 10 % NBF, dehydrated in series of graded concentrations of ethanol, clearing in xylol, embedded in paraffin. Sections of (5 μm) thick then stained with Mayer’s haematoxylin and eosin, PAS, combind PAS-AB (pH 2.5) and the Masson’s Trichrome. The results showed that the parotid gland was enveloped by thick dense fibrous connective tissue capsule and lumina of the acini are narrow.
Around the acinar cells, myoepithelial cells may be seen, and the intercal ated ducts are lined by simple cuboid epithelial cells. Submandibular glands were coated by a capsule of dense fibrous connective tissue from which septa of connective tissue extended and divide the gland into several lobules and sublingual glands which is compound tubuloacinar gland the paranchyma are lobules, enclosed by layer of irregular connective tissue capsule, from it, the septa are raised and dividing it into various lobules in conclusion the salivary gland’s of guinea pig capture in Al-Samawa showed some differences of histological structures.
