Morphometric and High Resolution Scanning Electron Microscopy Study of Calomys callosus Major Palatine Nerve International Journal of Morphology
Tanisaki,Maurício; Ogawa,Koichi; Lapa,Rita de Cássia Ribeiro da Silva; da Silva,Marcelo Cavenaghi Pereira; Watanabe,Ii-sei.
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...

Neurorrhaphy Techniques: Comparative Stereological and Experimental Axonal Study International Journal of Morphology
Boer,Nagib Pezati; Batigalia,Fernando; Viterbo,Fausto; Faleiros,Humberto Regis de Paula; Ramos,Rogério Rodrigo; Simonato,Luciana Estevam; Boer,Luis Fernando Ricci.
There is a great variety of injuries that affect peripheral nerves derived from acquired or congenital degenerative diseases affecting the central nervous system that cause loss of sensorimotor functions. The objective of this work was to perform an end-to-side or side-to-side experimental axonal stereological study in order to compare volume density of axons, endouneuro and myelin sheath (and muscle mass) in peroneal and tibial nerves, with anastomosis contact from 0.25 cm to 0.50 cm. After approval of the Ethics Committe, 20 male Wistar rats were divided into four groups of five rats each (G1= end-to-side neurorrhaphy; G2= side-to-side neurorrhaphy of 0.25 cm; G3= side-to-side neurorrhaphy of 0 cm and G4= Control of normality). After 180 days, fragments...
