Measurements were made of the amounts of histamine extracted from patients with peptic ulcer disease and control subjects suffering from various gastrointestinal diseases. Patients with duodenal ulcer, gastric ulcer, or recurrent duodenal ulcer after proximal gastric vagotomy often had less gastric mucosal histamine than did normal controls. Cimetidine therapy increased the amounts of the hista...
Commensal microflora (normal microflora, indigenous microbiota) consists of those micro-organisms, which are present on body surfaces covered by epithelial cells and are exposed to the external environment (gastrointestinal and respiratory tract, vagina, skin, etc.). The number of bacteria colonising mucosal and skin surfaces exceeds the number of cells forming human body. Commensal bacteria co...
objective(s): prostaglandins have been shown to mediate the gastro-protective effect of sodium hydrosulfide (nahs) but effect of nahs on mrna expression of prostaglandin e2 receptors (ep1, 3-4; eps) has not been investigated. therefore, this study designed to evaluate the effect of nahs on mrna expression of eps receptors in response to mucosal acidification and distention-induced gastric acid ...
(1) Background: Oral mucosal infections are a commonly encountered clinical pathology in patients who consult dentists, mainly for dental diseases. Currently, the involvement of oral and cardiovascular neurological diseases, among others, is widely discussed literature. In present research, we elaborated comprehensive report on rare infections, including syphilis head neck tuberculosis. (2) Met...
Complement is present mainly in blood. However, following mechanical damage or inflammation, serous exudates enter the mucosal surfaces. Here, the complement proteins interact with other endogenous molecules to keep microbes from entering the parenteral tissues. One of the mucosal proteins known to interact with the early complement components of both the classical and the lectin pathway is the...
Genetic immunization holds great promise for future vaccination against mucosal infectious diseases. However, parenteral genetic immunization is ineffective in control of mucosal intracellular infections, and the underlying mechanisms have remained unclear. By using a model of parenteral i.m. genetic immunization and pulmonary tuberculosis (TB), we have investigated the mechanisms that determin...
The mucosal immune system consists of molecules, cells, and organized lymphoid structures intended to provide immunity to pathogens that impinge upon mucosal surfaces. Mucosal infection by intracellular pathogens results in the induction of cell- mediated immunity, as manifested by CD4-positive (CD4 + ) T helper-type 1 cells, as well as CD8 + cytotoxic T-lymphocytes. These responses are normall...
Background & Aims: Gastrointestinal diseases are common clinical conditions and due to the fact that in a significant number of endoscopic cases, the only finding is mucosal erythema,, this study was performed to evaluate the histopathological findings of gastrointestinal diseases with only mucosal erythema. Materials & Methods: In this analytical-descriptive and retrospective study, all gastr...
