Rabbits were immunized with the supernatant of a homogenate of non-cancerous gastric mucosa to obtain an antiserum. This antiserum, after absorption by human jejunal mucosa and liver tissue, produced precipitin lines with the supernatants of homogenates of gastric carcinoma and gastric mucosa. Fluorescent staining was attempted using this antiserum. Well-stained cytoplasms were observed in cell...

Objective(s): In the present study,a new series of 6-methoxy-2-arylquinoline analogues was designed and synthesized as P-glycoprotein (P-gp) inhibitors using quinine and flavones as the lead compounds. Materials and Methods: The cytotoxic activity of the synthesized compounds was evaluated against two human cancer cell lines including EPG85-257RDB, multidrug-resistant gastric carcinoma cells (P...

Oxidative stress is believed to initiate and aggravate many diseases including peptic ulcers and gastric carcinoma. We observed an increase in rat gastric mucosal lipid peroxidation (LPO) and superoxide dismutase (SOD) and a decrease in catalase (CAT) levels in cold restraint stress-induced gastric ulceration while, in clinical peptic ulceration and gastric carcinoma patients, an increase in se...

BACKGROUND Previous research has indicated a breed predisposition to gastric carcinoma in dogs. However, results to date are inconsistent since several studies have failed to prove such a predisposition. Better knowledge of breeds at risk could facilitate early detection of gastric carcinoma in dogs. The aim of the study was to retrospectively investigate the proportion and possible breed predi...

BACKGROUND The most common malignancy to cause gastric outlet obstruction is primary gastric adenocarcinoma and it is followed by carcinoma of the pancreas and gallbladder. Herein, we report a case of gastric outlet obstruction secondary to metastatic lobular breast carcinoma. CASE PRESENTATION Fifty-seven year old Caucasian female with recently diagnosed metastatic lobular breast carcinoma t...

OBJECTIVE To investigate the utility of gastrojejunostomy for the palliation of gastric outlet obstruction in irresectable or incurable gastric carcinoma. METHODS This is a retrospective review of 67 patients who underwent a gastrojejunostomy for gastric outlet obstruction caused by gastric carcinoma between 1 January 1996 and 31 May 2003. RESULTS There were 19 complications after surgery, ...

INTRODUCTION Regulator of chromosome condensation 1 (RCC1) is a critical cell cycle regulator. We firstly identified RCC1 gene hypermethylation in gastric tumor tissues using the differential methylation hybridization (DMH) microarray, but the role of RCC1 in the pathogenesis of gastric carcinoma is largely unknown. METHODS Three gastric cancer cell lines (AGS, MKN45, and TSGH9201) were used ...

Licorice extracts have been widely used in herbal and folk medications. Glycyrrhiza contains diverse range of biological compounds including triterpenes (glycyrrhizin, glycyrrhizic acid) and flavonoids (quercetin, liquiritin, liquiritigenin, glabridin, licoricidin, isoliquiritigenin). The flavonoids in licorice are known to have strong anti-cancer activities. Quercetin, the most abundant flavon...

PURPOSE Metastasis is the leading cause of death for gastric carcinoma. An epigenetic biomarker panel for predicting gastric carcinoma metastasis could have significant clinical impact on the care of patients with gastric carcinoma. The main purpose of this study is to characterize the methylation differences between gastric carcinomas with and without metastasis. EXPERIMENTAL DESIGN Genome-w...

OBJECTIVE The prognosis for gastric carcinoma patients with liver metastasis is very poor. This retrospective study investigated the prognostic significance of MK-1 expression in gastric carcinoma patients with liver metastasis. METHODS Immunohistochemical staining using monoclonal antibody FU-MK-1 against MK-1 antigen was performed on paraffin-embedded tissues from 64 gastric carcinoma patie...
