today bleach and detergents are being frequently used and some people use their mixture for more cleaning. because of chemical interaction of bleach and detergent, chlorine gas was released and thereby it could be dangerous for human health. this study examined the effects of exposed toxic mixture of bleach and detergent on the mucosa layer and lamina mucosa conjunctiva in the mice. in this stu...

Thirty clinically healthy Stara Zagora white turkeys (15 females and 15 males) were used for the study. Eighteen tissue samples (six from middle of each segment small intestine) appropriate age group to prepare permanent histological specimens. The sections stained by Masson - Goldner method. intestine turkey was composed four layers: tunica mucosa, submucosa, muscularis serosa. Tunica mucosa h...

Osteonecrosis of the jaw (ONJ) is an adverse outcome associated to bisphosphonate treatment. However, it is not known whether the ONJ lesion originates in the bone, or whether it may initiate in the oral mucosa. The aim of our study was to evaluate the pattern of basal lamina of oral mucosa after bisphosphonate administration and to analyze the structural damage of the mucosa in ONJ patients, a...

The distribution of basophiloid cells in nasal mucosa was examined both in the patients of nasal allergy and normal controls . Basophiloid cells were stained in alcian blue (P .H. 5.8) with 0.4M MgCl2. 1 ) The basophiloid cells in the nasal mucosa of allergic patients were far outnumbered those of normal controls. 2) The basophiloid cells in the epithelial layer were very few in normal controls...

Excluding parenteral transmissions, virtually all vertical and homosexual transmission of human immunodeficiency virus type 1 (HIV-1) occurs via the gastrointestinal tract. Cellular routes implicated in the translocation of virus across the epithelium include M cells, dendritic cells, and epithelial cells. Intestinal epithelial cells express CCR5 and can selectively transfer CCR5-tropic HIV-1, ...

The current study was designed to identify the histological composition of ileum in Caucasian squirrel Sciurus anomalus. Ten adult squirrels were used for present study. Animals anesthetized, anatomized, fixed specimens 10% formalin solution, and conducted a series staining techniques. consists four main tunicae represented by mucosa, submucosa, muscularis, serosa. tunica mucosa three secondary...

An histological and histochemical study was conducted on the stomach of adult Senegal sole, Solea senegalensis specimens. The stomach was made up of four distinct layers: mucosa, lamina propria-submucosa-, muscularis and serosa. Surface epithelial, glandular and rodlet cells were present in the mucosa. Cells of the columnar epithelium contained a basal nucleus. Numerous mitochondria, granular e...

Comparative histology of the caecum of adult cattle,sheep and goat was studied. Caecum of all three animals consisted of four layers namely tunica mucosa, tela submucosa,tunica muscularis and tunica Serosa. Intestinal glands were mostly located at base region of tunica mucosa . In caecum of goat mucus secreting intestional glands were present in the close vicinity of lamina muscularis and serou...

Listeria monocytogenes is an intracellular bacterium that causes systemic infections after traversing the intestinal mucosa. Clearance of infection and long term protective immunity are mediated by L. monocytogenes-specific CD8 T lymphocytes. In this report, we characterize the murine CD8 T cell response in the lamina propria and intestinal epithelium after enteric L. monocytogenes infection. W...

This study aimed to measure the thickness of the epithelium and lamina propria of the palatal mucosa and to elucidate the location of the greater palatine artery to provide the anatomical basis for subepithelial connective tissue grafting. Thirty-two maxillary specimens, taken from the canine distal area to the first molar distal area, were embedded in paraffin and stained with hematoxylin-eosi...
