By MONTAGUE LAisn AND CLARENCE P. ALFREY, Jn. T HE RAPID INDUCTION of experimental riboflavin deficiency in man resulted in the development of a severe anemia which was reversed by riboflavin administration.1’2 In addition to the anemia, the patients developed a deficiency syndrome characterized by sore throat, hyperemia and edema of the pharyngeal and oral mucous membranes, cheilosis, angular ...

Oncocytic Schneiderian papilloma, fungiform papilloma, and inverted papilloma are 3 morphologically separate tumors arising from the Schneiderian membrane. Oncocytic Schneiderian papillomas comprise about 3 approximately 5% of this entity. Old-aged group predominates. No sex predilection is noted. Multi-layered eosinophilic epithelium characterizes this kind of tumor. Exophytic and inverted gro...

Atrophic glossitis is a condition characterised by absence of filiform or fungiform papillae on the dorsal surface of the tongue. Consequently, the ordinary texture and appearance of the dorsal tongue, determined by papillary protrusion, turns into a soft and smooth aspect. Throughout the years, many factors, both local and systemic, have been associated with atrophic glossitis as the tongue is...

Background Dietary habit among vertebrates depends upon the morphological and anatomical structure of tongue.Aim We here compare between morphological, histological aspects tongue Coturnix coturnix (granivorous bird) R. aegyptiacus (fruit-eating mammal).Method Six individuals each species were used; tongues removed, photographed, processed for histological, histochemical, scanning electron micr...

Transient receptor potential vanilloid subfamily member 1 (TRPV1) is activated by capsaicin, acid, and heat and mediates pain through peripheral nerves. In the tongue, TRPV1 expression has been reported also in the epithelium. This indicates a possibility that sensation is first received by the epithelium. However, how nerves receive sensations from the epithelium remains unclear. To clarify th...

Delayed rectifying K+ (DRK) channels in taste cells have been implicated in the regulation of cell excitability and as potential targets for direct and indirect modulation by taste stimuli. In the present study, we have used patch-clamp recording to determine the biophysical properties and pharmacological sensitivity of DRK channels in isolated rat fungiform taste buds. Molecular biological ass...
