Histology and mucosubstance histochemistry of mongoose salivary glands.

The histology and mucosubstance histochemistry of the mongoose salivary glands were studied. Histologically, the mongoose salivary glands were generally similar to those in other carnivores (dog, cat and ferret). The mucosubstance histochemistry demonstrated considerable variations in the parotid, submandibular and sublingual glands in comparison to the other carnivores. The partoid gland contained carboxylated mucin which was sialidase-resistant. Granules in a few cells also contained sulphated mucin. Both submandibular and sublingual glands contained mainly carboxylated sialomucin which was sialidase-labile except in a few cell, some neutral mucin but no sulphated mucin. The molar and zygomatic glands were similar to those in the other carnivores. They contained both sulphated and carboxylated mucins but no neutral mucin. The carboxylated mucin was sialidase-resistant.
