a histological and histochemical study of the stomach (proventriculus and gizzard) of the passer domesticus was carried out, under light microscopy.in the present study, we prepared 12 adult passer domesticus (both sex) captured in the country side of mashhad, iran. after euthanasia with ether inhalation, the digestive tract was exposed and fragments of the stomach (proventriculus and gizzard) ...

giant cell fibroma (gcf) was described as a new entity of fibrous hyperplastic soft tissue. it seems that stimulus from an unexplained origin can have a role in its etiology. histopathologically gcf is consisted of multinucleated fibroblasts that have oval shape nuclei within the eosinophilic cytoplasm. surgical excision is the treatment of choice and recurrence is very rare. here we report a c...

Background: Every 1 person out of 3 people with obstructive jaundice will die from complications jaundice. The absence bile salts causes the loss protective layer intestinal mucosa, which an increase in permeability wall, triggering process translocation various bacteria tract to blood circulation so that it can trigger septicemia and sepsis. Dadih or commonly known as ampiang dadih is a fermen...

Allen, Adrian, and Gunnar Flemström. Gastroduodenal mucus bicarbonate barrier: protection against acid and pepsin. Am J Physiol Cell Physiol 288: C1–C19, 2005; doi:10.1152/ajpcell.00102.2004.—Secretion of bicarbonate into the adherent layer of mucus gel creates a pH gradient with a near-neutral pH at the epithelial surfaces in stomach and duodenum, providing the first line of mucosal protection...

Secretion of bicarbonate into the adherent layer of mucus gel creates a pH gradient with a near-neutral pH at the epithelial surfaces in stomach and duodenum, providing the first line of mucosal protection against luminal acid. The continuous adherent mucus layer is also a barrier to luminal pepsin, thereby protecting the underlying mucosa from proteolytic digestion. In this article we review t...

Bladder neck (BN) dissection is considered one of the most challenging steps during robot-assisted radical prostatectomy. Better understanding of the BN anatomy, coupled with a standardized approach may facilitate dissection while minimizing complications. We describe in this article the 4 anatomic spaces during standardized BN dissection, as well other technical maneuvers of managing difficult...

We have shown that IL-1beta and IL-6, possibly originating from the mucosa in response to injury, inhibit neurally mediated contraction of esophageal circular muscle but do not affect ACh-induced contraction, reproducing the effect of experimental esophagitis on esophageal contraction. To examine the interaction of mucosa and circular muscle in inflammation, we examined the effect of HCl on in ...

In 1930 Delrue (1) reported that the isolated gastric mucosa of the frog, when mounted properly in a dual-chambered bath, will secrete acid and will respond to the addition of drugs. The same author subsequently demonstrated (2) the effects of varying the ionic composition of the artificial medium on the in vitro production of acid. The theoretical importance of this approach to the study of th...

UNLABELLED INTRODUCCION: Cytokeratins (CK) are molecules of the cytoskeleton that contribute to the cellular differenciation. We studied the expression of CK1, CK13 and CK14 in thirty-three patients with OLP. The biopsied lesions were located in the dorsal surface of the tongue, the palatal keratinized mucosa and the nonkeratinized buccal mucosa. OBJECTIVES This study aimed to determine the e...

We examined the effects of the calcitonin gene-related peptide (CGRP), including the possible participation of nitric oxide (NO), on mucin biosynthesis in the surface epithelium and remaining deep mucosa as well as the entire mucosa and compared the distribution of CGRP and NO synthase (NOS) using a combination of double immunofluorescence labeling and multiple dye filter. Pieces of tissue obta...
