Helobdella bowermani n. sp. is described from specimens collected in fine sediment of open water benthos of Upper Klamath Lake, Klamath County, Oregon. The new species has pale yellow/buff coloration with scattered chromatophore blotches throughout the dorsal surface, lateral extensions or papillae only on the a2 annulus, dorsal medial row of papillae with small papilla on al and larger papilla...

Amphipsyche meridiana Ulmer, 1909. larvae from the River Pasak below the Pasak Jolasit Dam were examined for alteration of morphological structure such as the anal papillae, surface, and tracheal gills of the larvae. The tracheal gills were the most altered followed by surface and anal papillae. Factors such as conductivity, and inputs of orthophosphate, sulfate, turbidity, other contaminants, ...

The morphology of typical anuran amphibian papillae is thoroughly distinct from that of urodeles. However, the morphological discontinuity lies not between the frogs and the salamanders, but between the most primitive living frog, Ascaphus truei, and the more derived anurans. Three features distinguishing the papillae of more derived anurans from that of Ascaphus apparently provide peripheral t...

Cephalobellus lobulata n. sp. (Oxyurida: Thelastomatidae) a parasite of the mole cricket Neocurtilla claraziana Saussure (Orthoptera: Gryllotalpidae) found in Argentina is described and illustrated. It is characterized by a short buccal cavity armed with three teeth, a striated cuticle with the first annule wide with four lobes and the second annule divided in twelve lobes. The male have three ...

Glossitis, known clinically as "redtongue," was studied in tissues from 34 military working dogs (MWD) in the Republic of Vietnam. This condition was manifested grossly by loss of lingual papillae on the dorsal margins of the rostral third of the tongue. Microscopically, the principal lesions consisted of loss of filiform papillae, hemorrhage and edema in the lamina propria, acanthosis, and cel...

OAKLEY, B. Reformation of taste buds by crossed sensory nervps in the rat’s tongue. Acta physiol. scand. 1970. 79. 88-94. Rat taste buds degenerate and disappear when their nerve supply is cut. Regeneration of the taste nerve fibres causes certain epithelial cells to differentiate into slender receptor cells comprising the taste bud. In this study by cross-union the glossopharyngeal (IXth) nerv...

OBJECTIVE To summarize the diagnosis and treatment of juxta-ampullary duodenal diverticulum (JAD) in our hospital. METHODS Of 5000 consecutive endoscopic retrograde cholangiopancreatography (ERCP) performed in our department, 225 patients were diagnosed with JAD and treated. All patients were classified based on the location of Ampullae of Vater in relation to the duodenal diverticulum. Of th...

A new species of a philometrid nematode, Margolisianum bulbosum, is described from the subcutaneous tissue in the mouth (larvigerous females), head (males, ovigerous, and larvigerous females), and eye (preovigerous females) of the southern flounder, Paralichthys lethostigma, from Mississippi Sound. It is placed in a new genus diagnosed by the combination of 8 large, paired but separate cephalic...

OBJECTIVE To report a case of pigmented fungiform papillae on the tongue. CLINICAL PRESENTATION AND INTERVENTION A 29-year-old female presented with patchy pigmented areas on her tongue of 2 years' duration. Examination of the tongue showed pigmentation confined to the fungiform papillae on the dorsum of the tongue. She was healthy and was not taking any medications and hence a diagnosis of p...
