1. Estudo HistopatolÃgico e MorfomÃtrico de Papilas Linguais Circunvaladas e Tecidos Associados em IndivÃduos Brasileiros Fumantes e nÃo Fumantes
A papila circunvalada difere de outras estruturas gustatÃrias por ser rica em botÃes gustativos e pela presenÃa de um aparato secretÃrio associado com glÃndulas serosas especializadas, a glÃndula de Von-Ebner. Esta pesquisa avaliou as possÃveis alteraÃÃes histopatolÃgicas nas papilas e em tecidos associados em relaÃÃo ao hÃbito tabagista. Foram

2. Caracterização morfológica, funcional e de ocorrência das tonsilas linguais laterais / Morphology characterization, function and occurrence of the lateral lingual tonsils
This study aimed to characterize the lateral lingual tonsils as to their morphology, function and occurrence. The experimental group I was composed of 25 specimens of human tongues fixated and kept in 10% formalin until processing. The specimens were radiographed for detection of any mineralized tissue. The specimens were examined by naked eye and with aid o

3. Study of the lingual mucosa and surface of interface epithelium-connective tissue of the maned sloth (Bradypus torquatus, Iliger, 1811), employing light and scanning electron microscopy methods / Estudo da mucosa da língua e da superficie de interface epitélio-tecido conjuntivo da preguiça-de-coleira (Bradypus torquatus, Iliger, 1811), empregando os métodos de microscopia de luz e eletrônica de varredura
Estudo das superfícies dorsal e ventral da língua e da superfície de interface epitélio-tecido conjuntivo de Bradypus torquatus, foi realizado empregando-se os métodos de microscopia de luz e microscopia eletrônica de varredura. As línguas de Bradypus torquatus foram removidas, dissecadas e seccionadas em 3 partes: rostral, média e caudal e tratadas

4. Light and scanning electron microscopic study on the lingual papillae and their connective tissue cores of the Cape hyrax Procavia capensis
We examined the epithelial surface and connective tissue cores (CTCs) of each lingual papilla on the Paenungulata, Cape hyrax (Procavia capensis), by scanning electron microscopy and light microscopy. The tongue consisted of a lingual apex, lingual body and lingual root. Filiform, fungiform and foliate papillae were observed on the dorsal surface of the tong

5. Morphology of the dorsal lingual papillae in the lesser mouse deer, Tragulus javanicus.
The dorsal lingual papillae of the lesser mouse deer were studied morphologically using light and scanning electron microscopy. Four types of papillae, filiform, fungiform, vallate and foliate, were observed. Filiform papillae consisted of larger main papillae with smaller secondary papillae on their anterolateral aspects. Secondary papillae were well distri

7. Autonomic mechanisms underlying capsaicin induced oral sensations and salivation in man.
The effects of capsaicin, citric acid and nicotine applied to the apex or radix of the tongue on taste sensations and salivation were studied in relation to the presence of substance P immunoreactive neurones in man. Application of capsaicin (30 micron) to the apex of the tongue or to the palatinal mucosa, but not to the radix of the tongue, caused a reprodu

8. Prion Infection of Skeletal Muscle Cells and Papillae in the Tongue
The presence of the prion agent in skeletal muscle is thought to be due to the infection of nerve fibers located within the muscle. We report here that the pathological isoform of the prion protein, PrPSc, accumulates within skeletal muscle cells, in addition to axons, in the tongue of hamsters following intralingual and intracerebral inoculation of the HY s

9. Biochemical studies of taste sensation: binding to taste tissue of 3H-labeled monellin, a sweet-tasting protein.
Binding of 3H-labeled methylated monellin to taste receptor tissue was demonstrated in vitro. Preparation of bovine and human circumvallate (taste) papillae bound more of the ligand than did lingual and nonlingual epithelial preparations devoid of taste buds. Binding to the taste preparations saturated at high ligand concentrations. Furthermore, sugars and

10. Gustatory trophic action of arterial chemosensory neurones in the cat.
The proximal stump of the carotid sinus nerve (c.s.n.) branch of the IXth cranial nerve was surgically cross-anastomosed to the distal stump of the lingual nerve (l.n.) branch of the same cranial nerve to test the ability of regenerating c.s.n. axons to reinnervate and induce taste buds on cat circumvallate papillae. The l.n. branch of the IXth nerve, which
