background: icu patients especially those under mechanical ventilation or with a history of coagulation disorders are at the risk of stress ulcer development and related gi bleeding. typically h2 blockers administration showed prophylactic role to control gastric acidity. preliminary studies have shown that administration of intravenous omeperazol is effective. the object of this study was to c...
background: this study aimed to compare intermittent intravenous (iv) pantoprazole and ranitidine for control of gastric acid secretion and the possible prevention of upper gastrointestinal bleeding (ugib) in critical care patients. methods: this was a randomized, double blind clinical trial study of iv pantoprazole (40 mg every12 hour) or intermittent iv ranitidine (50 mg bolus every 8 hour) i...
Background: Attempts for early detection of gastric cancer have recently focused on host's genetic susceptibility factors and gene-environment interactions. We have, herein, studied the association of MTHFR C677T single nucleotide polymorphism (SNP) and its interaction with Helicobacter pylori infection, smoking, age and gender on the risk of gastric cancer among an Iranian population. Methods:...
Background: Opioid peptides and their receptors are present in the majority of body tissues including gastrointestinal tract. Heroin is one of the opioid derivatives that abuse increasingly today. So far, there is no study on the effect of acute heroin administration on gastric acid and pepsin secretion. Objective: To define the effect of the acute heroin consumption on basal and vagal-stimu...
Background and Aims: Helicobacter pylori is the main cause of various gastroduodenal diseases. It is estimated that app roximately, more than half of the adult population in developed countries and 90% of people in developing countries infected with H. pylori. H. pylori infection may be related to Genetic of virulence factors and environmental factors. The aim of this study was to assess of fre...
Cytochrome P450 2E1 (CYP2E1) enzyme metabolically activates a large number of low molecular mass xenobiotics probably involved in gastric cancer incidence through activation of procarcinogens. North of Iran is amongst high incidence rate areas of gastric carcinoma where environmental carcinogenic compounds, including agricultural pesticides, are massively used. In this report, we quantitatively...
Background: Gastric and colorectal adenocarcinoma are the second and the fifth most common cancers in Iran, respectively. Expression of cytokeratin 7 (CK7) is established in most malignancies including gastric and colorectal adenocarcinoma. Demonstration of Ck7 could be related to prognostic factors and help to the better management of the patients. The objective of our study was to evalu...
Cancers are the 2nd cause of death, especially gastric and esophagus cancers are among the most fatal cancers in Iran. The aim of the present study is to estimate and compare the survival rates in patients with gastric and esophagus cancers. Materials and Methods: After extracting information of patients with gastric and esophagus cancers registered in cancer registry of Fars province, they fo...
Background and Objective: The gastric residual volume has a direct effect on the volume and timing of the subsequent feeding and causes gastric emptying and pulmonary aspiration. The present study compares the effect of Cydonia oblonga and Phyllanthus Emblica (Amla) fruit on gastric residual volume and pulmonary aspiration in mechanically- ventilated patients. Materials and Methods: This is a...
background host genetic and environmental factors are involved in development of gastric cancer. tumor necrosis factor (tnf)-î±| has a key role in helicobacter pylori -induced gastritis. we analyzed the association between tnf-î± polymorphism and the risk of gastric cancer in an iranian population residing in northeastern iran. materials and methods in a case-control study, the genotyping was c...
