Última Transmission Electron Microscopy Study of the Neonatal Rat Tongue Mucosa Treated with Special Attention to the Bacteriae on the Epithelial Cell Membrane International Journal of Morphology Picoli,Lara Cristina; Lopes,Ruberval A; Semprini,Marisa; Sala,Miguel Angel; Ogawa,Koichi; Watanabe,Ii-sei. The epithelial cell surfaces of neonatal Wistar rat tongue mucosa were examined by transmission electron microscopic method. The tissues were fixed by modified Karnovksy solution and embedded in Spurr resin. Thin sections of 90 nm thickness were cut and examined in the Jeol 1010 transmission electron microscopy. It was revealed that the queratinized squamous epithelial cells of the tongue mucosa exposed to cadmium presented groupings of numerous bacteriae which are attached to the flat cell membrane surfaces. The coccus and bacillus are attached to the cell membrane in organized rows or at random, as clearly seen in the TEM images. At high magnification, the transmission electron microscopic images showed that bacteriae are attached by a fibrillar...

The characteristics of Calomys callosus major palatine nerve were studied employing light, transmission and high resolution scanning electron microscopy methods. For light microscopy, the specimens were fixed in Bouin's fixative solution, processed routinely and the sections were stained with hematoxylin­eosin and Azo-Carmin to identify nerve fibers. For high resolution scanning electron microscopy the O-D-O method reported by <a href="#13">Tanaka (1989)</a> was used to examine nerve fiber components and to measure the myelin sheath. Thin sections were examined by transmission electron microscopy to show axoplasmic elements and adjacent structures. The results revealed nerve fiber bundles in the lamina propria of Calomys callosus palatine...

The characteristics of intrinsic muscle fibers in the anterior third of the adult rat tongue were studied employing light microscopy, SEM and high-resolution SEM (HRSEM) methods. For light microscopy, specimens were fixed in Bouin's solution and embedded in paraffin. In order to identify the muscle fibers and bundles of collagen fibers, frontal sections were stained with hematoxylin-eosin, azo-carmin and picro-sirius. The results showed that muscle fibers near the lamina propria are fixed with connective tissue, constituting several groups. The bundles of muscle fibers are arranged in longitudinal, vertical and transversal directions. For SEM, specimens were fixed in modified Karnovsky solution and freeze-fractured in liquid nitrogen revealed the collagen...

The objective of the present study was to analyze morphological aspects of the structures of the stomatognathic system and their relationship with malocclusion. For this purpose, we determined the morphological alterations that occur in the masseter muscle of guinea pigs (Cavia porcellus) after the induction of malocclusion by extraction of the left upper molars. Animals were divided into two groups (malocclusion and control group) and submitted to macroscopic, biometric and light microscopic analyses. The results showed a reduction in the width of the masseter muscle mainly in left side in the malocclusion group 60 days after unilateral extraction. Microscopically, round and polygonal muscle fibers of several diameters were observed, and altered muscle...

In the present paper were analysed the three-dimensional characteristics of the interface epithelium-connective tissue surface of finger prints of Cebus apella monkey employing the scanning electrón microscopic methods. The connective tissue core (CTC) and epithelial papillae were examined verifying the three-dimensional configuration of the tissue projections. The samples were fixed in Bouin solsution for histologic preparations and in modified Karnovsky for examine to observe in scanning electrón microscopy. After treatment in the 10% NaOH solution during 3 to 5 day s, the surface of finger prints revealed a distribution of CTC of lamina propria in situ showing original three-dimensional SEM images. The linear and circular dispositions CTC, and the... Tipo: Journal article Palavras-chave: Skin; Finger; Collagen fibers; Cebus apella; Scanning electron microscopy. Ano: 2008 URL: http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0717-95022008000200013 Sensory nerve endings in the rat cheek mucosa: an electron microscopic study Braz. J. Vet. Res. Anim. Sci. Watanabe,Ii-sei; Silva,Marcelo Cavenaghi Pereira da; Kronka,Marcia Consentino. The sensory nerve endings of the rat cheek mucosa were studied using the transmission electron microscopy. The specimens were fixed in modified Karnovsky solution and embedded in Epon resin. The sensory nerve endings showed a central terminal axon containing numerous mitochondria, neurofilaments, microtubules and clear vesicles. The proximal part of corpuscle revealed the cytoplasmic extensions of lamellar cells and the perineural cells. The fine bundles of collagen fibers are identified in the interlamellar spaces and the external part of corpuscle. Numerous concentric lamellae showed caveolae, interlamelar spaces filled with amorphous material, desmosome-type junctions between adjacent lamellae and the inner lamellar cells and the axoplasmic membrane....
