introduction: the effect of esophageal distension (ed) on gastric motility has been well documented, but a few investigations have been carried out on the effect of ed on gastric secretion. the aim of this study was to investigate the effect of ed on gastric acid and pepsin secretion and the mechanism(s) involved. methods: male adult wistar rats (200-240 g) were anesthetized with urethane (1.2 ...

Abstract Introduction: There are many studies about the inhibitory effect of the esophageal distention (ED) on gastric motility. Recently, it has been shown that ED decreases the gastric secretions. It is well established that the inhibitory effect of ED is mediated by activation of vago-vagal inhibitory reflex. However, there is not any investigation about the effect of the reflex on the gast...

introduction and aims: both observational and experimental studies have shown that higher selenium status reduces the risk of upper gastrointestinal cancers in selenium deficient populations. recent cancer registry data have shown very different rates of esophageal cancer (ec) and gastric cancer (gc) in four provinces of iran, namely ardabil, mazandaran, golestan, and kerman. the aim of this st...

Transjugular intrahepatic portosystemic shunt (TIPS) placement is a standard procedure for the treatment of portal hypertension complications. When this conventional approach is not feasible, alternative procedures for systemic diversion of portal blood have been proposed. A one-step interventional approach, combining minilaparotomy-assisted transmesenteric (MAT) antegrade portal recanalization...

Background & Aims: Esophageal and gastric cancers are among prevalent cancers in the world and it is believed that nitrate and nitrite contaminations of drinking water are important factors in increasing the risk of these cancers. This study was designed to determine the correlations between these factors and upper gastrointestinal cancers. Methods: In this ecologic study, mean concentrations o...

conclusions this study suggests that the vaca pcr can be very useful in diagnosis, treatment, and follow-up of patients with gastritis and pud. the pcr assay and clo test can complement and confirm each other in identification and eradication of cancer-related strains of h. pylori. the exclusion of patients with suspected achlorhydria from the study is likely a reason for the lack of false posi...
