The diagnosis of lingual abscess in the anterior two-thirds of the tongue is simple in view of the characteristic symptoms and signs. Our patient’s initial diagnosis was confused, possibly because of his lack of communication and the fact that he was apyrexial. Hereditary angioneurotic oedema, caused by C1 esterase inhibitor protein deficiency, usually presents with a triad of symptoms and sign...

Because intraoral capsaicin is reported to reduce the perceived intensity of certain taste qualities, we investigated whether it affects the central processing of gustatory information. The responses of gustatory neurons in the nucleus tractus solitarius (NTS) to tastant stimuli were recorded before and after lingual application of capsaicin in anesthetized rats. Thirty-four NTS units were char...

There have been many reports on the ultrastructure of the lingual taste organs, sensory papillae, of frogs (Uga, 1966; Uga and Hama, 1967; Graziadei and DeHan, 1971; Stensaas, 1971; Hirata and Nada, 1975; During and Andres, 1976; Jeager and Hillman, 1976; Graziadei, 1975). However, among these papers, only a few describe tridimensional ultrastructural studies on the lingual epithelial surface b...

The aim of the present study was to investigate the light and electron microscopic structure of the tongue in pigeon. Three parts are distinguished in the dorsal surface of the tongue: the apex, the body and the root of the tongue. On the dorsal surface of the apex and body of the tongue a median groove is found. Large conical papillae are located symmetrically in the form of the letter U in th...
