The immune responses to Helicobacter pylori infection play important roles in gastroduodenal diseases. The contribution of gamma interferon (IFN-gamma) to the immune responses, especially to the induction of gastric inflammation and to protection from H. pylori infection, was investigated with IFN-gamma gene knockout (IFN-gamma-/-) mice. We first examined the colonizing abilities of eight H. py...

Gastroscopy and biopsy for the rapid urease test and histopathological examination have been still standard diagnosis for H. pylori infection. Many studies have been attempted to classify the gastroscopic findings of H. pylori related gastritis. In 2002, Japanese endoscopist found that collecting venules, seen as numerous minute red dots in the gastric corpus, where a characteristic finding in ...

Persian oak (Quercus brantii Lindl.) belongs the family Fagaceae, is a medicinal plant which seed flour is used to treat inflammatory and gastric ulcers by the tribes in south western Iran. The current study was done to evaluate the effect of hydro-alcoholic extract of Q. brantii seed flour for treatment of gastric ulcers induced by ethanol in Wistar rats. The hydro-alcoholic extract of Q. bran...

PURPOSE Cyclooxygenase (Cox) is the key enzyme in conversion of arachidonic acid to prostanoids. Two Cox genes have been cloned, and expression of Cox-2 mRNA and protein has been shown to be elevated in several human malignancies and in animal models of carcinogenesis. The purpose of this study was to investigate Cox-2 protein expression in human gastric dysplasias and adenocarcinomas. EXPERI...

sarcoidosis is a systemic granulomatous disease of unknown etiology. sarcoidosis involving the gastrointestinal (gi) tract is extremely rare. this is a rare case report of an individual with symptomatic gastroduodenal sarcoidosis. a 34-year-old male with a six-month history of epigastric pain, nausea, early satiety and weight loss presented to our clinic. an upper endoscopy was performed which ...

Under acute stress conditions in the rat, there is rapid and transient increase in circulating prolactin (PRL). This leads to an elevated expression of the long form of PRLR (PRLR-L) first in the hypothalamus and the choroid plexus. This increase in PRL is involved in the inhibition of stress-induced hypocalcemia and gastric erosion. In this study we used rat PRL and a PRLR morpholino-antisense...

The value of ultrasonography (US), magnetic resonance imaging (MRI), computed tomography (CT) and plain radiography (PR) in detecting bone erosions on the humeral head was evaluated in a study of 26 in-patients (26 shoulders) with rheumatoid arthritis (RA). MRI depicted humeral erosions in 25 (96%), US in 24 (92%), CT in 20 (77%) and PR in 19 (73%) of the 26 shoulders. MRI and US were superior ...
