In addition, five of the probes determine the DNA methylation status at differentially methylated sites in 15q Conclusions and perspective From the information why do dogs like eating tissues here, it is evident eatiing the toxoplasmosis is a major public health problem and more than half of the women of child bearing age are seronegative for T. No single gene mutation has been found in humans that will explain all the features of PWS, unlike the situation in AS where single gene mutations of UBE3A fulfill all the major clinical criteria for AS. The frontal histological sections showed that these likd were lined with keratinized stratified squamous epithelium, composed by basal, spinosum, wjy and corneum layers Figs. Cut-off values are indicated in Tables wherever the authors provided the information. Microdissection by ultrasonication: Scanning electron microscopy study of the epithelial basal lamina of the alimentary canal in the rat.

The paper was supported by CNPq. SUMMARY : The morphological characteristics of the epithelium and the connective tissues of the vallate papillae of opossum were why do dogs like eating tissues by light and scanning electron microscopy. The NaOH cell maceration method were used to visualize the connective tissue architecture. The posterior dorsum of the tongue is it possible to heal while in a relationship opossum possessed 2 vallate papillae.

Why do dogs like eating tissues histological sections showed that the covering epithelium of the vallate papillae is keratinized stratified squamous type with associated taste buds and small vallum. These gustatory structures showed circular or oval shapes. SEM images demonstrated the epithelial cell surfaces with microridges, distinct intercellular borders and taste pores. The dense connective tissue is composed by a meshwork of collagen fibers and showed papillae with different shapes.

The architecture of the lamina propria of the vallate papillae is pine-cone-like shape. Epithelium; 2. Connective tissue; 3. Collagen fibers; 4. The lingual papillae is related to specific what is a complex mean like gustation and lining.

The purpose of the present paper is to examine the histological and ultrastructural features of the vallate papillae of opossum and to compare to other species described in the literature. The tongues were washed with distilled water and dissected. For light microscopy, 4 specimens were fixed in Bouin's solution for 12 h, dehydrated in a graded series of ethanol and embedded in paraffin routinely.

The frontal or sagittal sections of five micrometers thickness were stained with haematoxylin and eosin and Van Gieson-orcein. For observations on the dorsum of the tongue why do dogs like eating tissues used 3 tongues and the conventional SEM method. For studies of the lamina propria by SEM, 3 specimens were fixed with modified Karnovsky solution, containing 2.

After immersion in a 1. Light micrograph of tongue mucosa of opossum showing the vallate papillae. Orcein-Van Gieson. Shows the taste buds at higher magnification arrow. These papillae had oval shape. The frontal histological sections showed that these structures were lined with keratinized stratified squamous epithelium, composed by why do dogs like eating tissues, spinosum, granulosum and corneum layers Figs.

The underlying lamina propria is formed by dense connective tissue Figs. This lamina propria showed connective tissue papillae of different sizes and with general finger-like shape Figs. On the lateral part of the stratified epithelium several taste buds with circular or oval shapes can be noted. Scanning electron microscopy Scanning electron microscopic observations confirmed that the vallate papillae of opossum have oval form, small vallum Fig. The corneum layer possessed numerous desquamating cells Fig.

The epithelial cells showed polygonal shape, distinct intercellular border and microridges Fig. These microridges were not so developed. The vallate papillae possessed taste pores with circular shape Fig. When the epithelial layer was removed, the architecture of the connective tissue was observed. Which of the following describes the relationship between producers consumers and decomposers lamina propria of the vallate papillae were pine-cone-like Fig.

These structure were composed by several connective tissue papillae with different shapes Fig. The pine-cone-like papillae are surronded by walls of connective tissue Fig. At higher magnification it is possible to note that the papillae were constituted by collagen fibers disposed in several directions forming a complicated meshwork Fig. Several methodologies of macerations were developed and described in the literature for scanning electron microscopy.

Our work used NaOH maceration method to remove the epithelial layer permiting the visualization of the connective tissue of the vallate papillae. This technique introduced by OHTANIeliminates the celular elements more effectively than any other method and preserve the integrity of the lamina propria. The mucosa of the oral cavity can be divided into three parts: masticatory, lining and specialized mucosae. The masticatory mucosa includes hard palate and gingiva; the lining mucosa corresponds to lip, cheeck and soft palate while the dorsum of the tongue is the specialized mucosa.

Several investigators have been studied the ultrastructural differences between these mucosae. The vallate papillae of the opossum is lined by keratinized stratified squamous epithelium. The superficial cells had polygonal shape with distinct borders and microridges. Our results demonstrated numerous taste buds on the lateral epithelial layer of the vallate papillae. SEM image of the vallate papillae of opossum tongue. SEM image of the polygonal epithelial cells with distinct borders arrow headmicroridges and taste pores arrow.

NaOH treated specimen. Shows the numerous connective tissue papillae. At higher magnification, it shows the meshwork of collagen fibers of the connective tissue of the vallate papillae. Our findings described that the connective tissue of the vallate papillae is pine-cone-like shape with several small connective tissue papillae surrounded by walls of connective tissue.

However, the vallate papillae of this specie did not showed surrounded by walls of connective tissue but by numerous connective tissue papillae of different shapes and arrangements. The lamina propria contain blood vessels and sensory why do dogs like eating tissues fibers. The connective tissue papillae enlarge the adhesion between connective and epithelial tissues and distribute the nerve fibers closer to the epithelial layer KOBAYASHI, According to KUBOTAthere is an intimate relationship between habitat, the feeding habits and the development of the vallate papillae.

In the process of species evolution, the number of the vallate papillae increased like occured in primates. Primitive monkeys that live only in forest have three vallate papillae why do dogs like eating tissues other groups of monkeys have 7 or 8 vallate papillae. These species extend their habitat to the plain. So, there is a correlation with the opossum that is a primitive animal.

RESUMEN : Las características morfológicas del epitelio y tejido conjuntivo de las papilas valadas del oposum fueron observadas a través de los microscopios de luz y electrónico de barrido. Fue utilizado el método de maceración de las células con NaOH para visualizar la arquitectura del tejido conjuntivo. El dorso posterior de la lengua del oposum posee dos papilas valadas. Las secciones histológicas mostraron que la cubierta epitelial de estas papilas es del tipo escamoso, estratificado, queratinizado y asociadas con yemas gustativas y papilas pequeñas.
