Histological and Histochemical Studies of the Olfactory Organ in Bagrid Catfish Rita rita (Hamilton, 1822)
Padmanabha Chakrabarti and Saroj Kumar Ghosh

The cellular architecture and chemical nature of different cells lining the olfactory epithelium of Rita rita (Hamilton, 1822) were studied using histological and various histochemical techniques. Histological analysis demonstrated that each olfactory epithelium consists of supporting, receptor, labyrinth, basal and mucous cells. The localization and chemical nature of acid and neutral mucins in the different cells of the olfactory epithelium was studied histochemically by employing PAS-AB technique. Different shades of glycogen were discernible in the receptor cells along the epithelial border and flagellated supporting cells. Basic protein was noted in the various cells of epithelial lining as well as in the central core while bound lipid was restricted to the receptor cells and nerves present in the central core. The localization of various proportions of DNA and RNA were detected in the various cells lining the olfactory epithelium. The occurrence, distribution and localization of different histochemical tests in the olfactory epithelium were discussed with their functional significance.
