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...

BACKGROUND The eyelid structure can be divided into an inner layer and an outer layer. Reconstruction of a full-thickness eyelid defect is accomplished by full-thickness composite tissue transfer or combined layered reconstruction. We present a new technique for inner layer reconstruction using ear cartilage and oral mucosa. METHODS The oral mucosa graft is harvested from the inner side of th...

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...

The present study was designed to investigate the histochemical developmental changes of proventriculus at pre-hatching and post-hatching in northern bobwhite quail periods 11- 15-days addition 14- 21-days post-hatching. composed four tunics is tunica mucosa, sub-mucosa, muscularis, serosa. mucosa lined with simple columnar epithelium height increases age also thickness submucosa filled provent...

The antioxidative properties of pig urinary bladder mucosa were compared with those of gastric and intestinal mucosa using nitroxide radicals. Electron paramagnetic resonance (EPR) method was used to monitor the metabolic processes of nitroxides in mucosae. The reduction of nitroxides was measured on intact luminal surfaces of gastric, intestinal, and urinary bladder mucosa, as well as in homog...

A gelatinous coat, heterogeneous in appearance, was formed over damaged rat gastric mucosa recovering from acute ethanol injury. This coat, in places 1.6 mm thick (median thickness 680 microns), was 10 times thicker than the translucent layer of adherent mucus (median thickness 70 microns) covering the undamaged mucosa. Immunohistochemistry and periodic acid Schiff staining showed this gelatino...

Oral mucosa is composed of a stratified epithelial layer and underlying connective tissue. The structure of the oral mucosa and the connection of the epithelial layer to the underlying connective tissue are highly variable, depending on the intraoral region. The structural features of the different types of intraoral mucosa develop during the fetal period. Human gingival epithelium consists of ...

BACKGROUND The function of esophagus is to move food by peristaltic motion which is the result of the interaction of the tissue forces in the esophageal wall and the hydrodynamic forces in the food bolus. The structure of the esophagus is layered. In this paper, the esophagus is treated as a two-layered structure consisting of an inner collagen-rich submucosa layer and an outer muscle layer. We...

Lipid peroxidation in vitro was tested by malonaldehyde production in gastrointestinal mucosa and compared with other tissues. It was observed that gastrointestinal mucosa was resistant to both non-enzymatic and enzymatic lipid peroxidation. This was due to the presence of an inhibitor of lipid peroxidation in the membranous fractions of intestinal mucosa. This inhibitor was capable of inhibiti...
