Background: Review of the Iraqi literatures reviled that there are several works have been done on gastrointestinal tract birds, but we didn’t find research work include details information related with common wood pigeon from environment
 Aim: The current study aimed to investigate anatomy and histology intestine in (Columba palumbus). 
 Materials methods: Animals were collected Al-N...

oral lichen planus (olp) is a chronic inflammatory disease of the oral mucosa which is considered by the world health organization (who) as a premalignant condition. one step in malignant development is so called epithelial mesenchymal transition (emt), a process whereby epithelial cells acquire mesenchymal characteristics. a factor known to induce emt is the transforming growth factor-β (tgf-β...

objective(s):fumonisins are a group of toxic and carcinogenic mycotoxins, which contaminate the grains and their products. the aim of this study was to examine the apoptotic and proliferative activity of mouse gastric mucosa following administration of fumonisin b1 (fb1).    materials and methods: twenty-nine female mice divided into treatment (n=15) and control (n=14) groups. the treatment gro...

oral lichen planus is a chronic inflammatory immune-mediated disease. icam-1 and vcam-1 are vascular adhesion molecules that their receptors are located on endothelial cells and leukocytes. the aim of this study is the immunohistochemical evaluation of vcam1 and icam1 in oral lichen planus and to compare these two markers with normal mucosa for evaluation of angiogenesis. this descriptive-analy...

Waterpipe Tobacco Smoke(WTS) is an unhealthy life style that may increase the risk of genotoxic responses and chronic diseases such as cancer. Micronucleus test is a successful and reliable method which is used for screening of genetotoxic responses of whole body and also for screening those people who had already exposed to genotoxic compounds. In this study, specific questionnaires were desig...

Traumatic fibroma is a benign exophytic and reactive oral lesion that develops secondary to repetitive trauma or irritation. Most commonly affected sites are tongue, buccal mucosa, lower labial mucosa. These well demarcated, smooth, pedunculated sessile, lesions which similar the surrounding mucosa in color. Generally, it non-tender but local irritation may lead painful ulceration. Treatment pl...

Development of effective in vitro human lip models, specific to the vermilion epithelium, has not progressed as much that skin and oral mucosa/gingiva models vitro. Our histologic examination demonstrated a Japanese macaque (male, 7 years 9 months old) had distinct from adjacent mucosa, resembling histological characteristics lip. Therefore, this study, we examined gene expression profile three...

HIGHLIGHTS Phenolic derivatives exert a genotoxic effect on the oral mucosa. The use of personal protective equipment and/or exhaust laminar flow hood reduces effects. Long-term exposure to agents can be measured by mucosa samples.

Background: Olfactory ensheathing glia (OEG) has been shown to have a neuroprotective effect after being transplanted in rats with spinal cord injury. This study was conducted to determine the possible beneficial results of olfactory mucosa transplantation (OMT) which is a source of OEG on functional recovery and axonal regeneration after transection of the sciatic nerve. Methods: In this study...
