Abstract

As características tridimensionais dos componentes intracelulares de células acinares e de ductos foram reveladas usando o método ósmio-DMSO-ósmio. As amostras foram maceradas em solução de tetróxido de ósmio diluído após a fratura na solução de dimetil sulfoxido. As lamelas do retículo endoplasmático granular são reveladas entremeadas por várias mitocôndrias. As lamelas do retículo endoplasmático granular são localizados ao redor dos núcleos na porção basal e estas estruturas são observadas em imagens tridimensionais de microscopia eletrônica de alta resolução. The three-dimensional characteristics of the intracellular components of acinar and ductal cells were revealed using the osmium-DMSO-osmium method. The samples were macerated in diluted osmium after fractured in DMSO solution. The stacks of the rough endoplasmic reticulum are revealed intermingling by several mitochondria. The lamellae of the rough endoplasmic reticulum are located around the nuclei at basal portion and these structures are shown in three-dimensional HRSEM images.

Abstract

The agouti ( Dasyprocta aguti Linnaeus, 1766) is a wild rodent belonging to the family Dasyproctidae that is found throughout Brazil and feeds on fruits and seeds. The aim of the present study was to describe the following features of the tongue of agouti: its morphological structures, the three-dimensional characteristics of the lingual papillae surface, the connective tissue cores ( CTCs) and the epithelial cell ultrastructure. Four types of papillae were observed on the dorsal surface of the tongue with a triangular shape: filiform, fungiform, foliate and vallate. Filiform papillae were distributed throughout the tongue surface, and removal of the epithelial surface revealed conical CTCs and multifilaments. Fungiform papillae were observed in the rostral and middle regions, whereas foliate papillae developed in pairs on the lateral margin of the caudal region. Removal of the epithelium in these regions revealed CTCs with parallel laminar conformation. Vallate papillae were arranged in a V-shape in the caudal region, and their CTCs ranged in shape from elongate to ovoid. The ultrastructural components of the dorsal epithelium were the basal, spinous, granular and keratinised layers. A broad area with cytoplasmic projections was identified in the interface region between the lamina propria and the basal layer. Flattened cells with intermediate filaments were observed in the transitional region between spinous and granular layers. The keratinised layer was composed of superimposed epithelial cells where desmosomes and cell-surface microridges were observed. These structural features, including the three-dimensional aspects of the lingual papillae, the CTCs and the epithelial ultrastructure, indicate that when compared with other animals, particularly other rodent species, the morphological features of the tongue of agouti are relatively well developed, especially regarding foliate and vallate papillae.
