... synthesis of sugar/protein residues which are secreted and degraded within its lumen. The technique used made it possible to characterize the ultrastructural secretory pathways from the epithelial cells into the sac lumen. The results indicate that the ES may sense and respond to dynamic changes...

... rarely found. After stage 37 (embryonic day 11), otoconia-like bodies in the endolymphatic sac decreased in number and size. They were almost the same as the otoconia in the macular organs, ultrastructurally. These findings indicate that the endolymphatic sac of the chick embryos may possess the function...

... of melanocytes was higher in the upper half of the middle turn and in the apical turn than that in the ARNH group. Ultrastructural examination of epithelial and mesothelial cells as well as of melanocytes showed more pronounced cellular degeneration in patients with SNHL than in those with ARNH. A possible...

...Toshio Yoshihara; Hidemi Kaname; Tetsuo Ishii; Makoto Igarashi Vestibular dark cell areas in gentamycin (GM)-intoxicated guinea pigs were examined ultrastructurally and cytochemically. After GM treatment the dark cells represented cytoplasmic vacuoles, wide intercellular space, less osmiophilic...

...Tatsuo Matsunaga; Jin Kanzaki; Masazumi Masuda; Yasuhiro Hosoda The human vestibular dark cell (DC) areas of the utricle and ampulla of the lateral semicircular canal were investigated ultrastructurally in 7 patients with acoustic neurinoma. Two types of DCs mainly constituted the epithelial cells...

.... The purpose of this study was to examine the ultrastructure of the developing stria vascularis in the rat pup in order to correlate functional changes with structural alterations. Rat pups of various ages underwent EP measurement under Rompun anesthesia. The cochleas were rapidly removed under deep...

...Masaya Takumida; Dan Bagger-Sjöbäck The presence of carbohydrates in the glycocalyx of the vestibular end organs of the guinea pig was investigated at the ultrastructural level using lectin-gold solutions. The glycocalyx of both the sensory and the supporting cells has variable sugar components...

...Masaya Takumida; Dan Bagger-Sjöbäck; Helge Rask-Andersern The effect of acetazolamide on the ultrastructures of the murine endolymphatic sac was investigated. The animals were given a single intravenous dose of acetazolamide (100 mg/b.w.) and were sacrificed 0, 15, 30, 60 and 120 min after...

...Masaya Takumida; Jan Wersäll; Dan Bagger-Sjöbäck; Yasuo Harada The ultrastructure of the glycocalyx with special reference to the synthesizing process was studied in the guinea pig vestibular sensory cells using the tannic acid staining technique. The glycocalyx emerged from the outer layer...

...: We performed ultrastructural studies to assess whether lamellar bodies are present in the human sinus in a variety of diseased and normal epithelium. Methods: We biopsied sinus mucosa from 5 subjects, 1 each with allergic fungal sinusitis, eosinophilic mucin rhinosinusitis, cystic fibrosis, frontal...

...Peter Schenk; Alessandra Handisurya; Martin Steurer The ultrastructural morphology of a ceruminous gland adenoma in the middle ear was examined electron microscopically. The epithelial tumor cells displayed apocrine caps, microvilli, cell junctions, secretory granules, vacuoles, lipid droplets...
