Anti-Helicobacter pylori activities were determined by agar dilution, confocal laser scanning microscopy, and cell proliferation assays following treatment with various grape extracts. Muscadine grape skin possessed the strongest activity, followed by grape synergy (skin and seed) and seed, suggesting that higher phenolic levels do not necessarily determine overall anti-H. pylori efficacy.

The polymerase chain reaction was used to develop a method for the detection of Helicobacter pylori, a causative agent of gastritis, as well as for the elucidation of its mode of transmission. A genomic library of Helicobacter pylori DNA in Escherichia coli JM109 was constructed by cloning Hind III-digested DNA fragments into plasmid vector pUC18. The nucleotide sequences from seven recombinant...

To determine the frequency of Helicobacter pylori infection in patients with lichen planus presented to tertiary care hospital Hyderabad. Patiehts and Methods This cross sectional descriptive study of six months was carried at Liaquat University Hospital Hyderabad Sindh, Pakistan from February 2008 to July 2008. All patients above 12 years of age, of either gender, were known / already diagnose...

The role of Helicobacter pylori infection in the symptom complex associated with non-ulcer dyspepsia is uncertain, despite the presence of the organism in a high proportion of these patients. In order to exclude physician bias in history taking, 18 patients (9 female) diagnosed as non-ulcer dyspepsia, after endoscopy and gallbladder ultrasonography, underwent computer interrogation using the Gl...

BACKGROUND Osteoporosis affects approximately 30% of postmenopausal women. Gastrectomy, pernicious anemia, and more recently Helicobacter pylori infection, have all been implicated in the pathogenesis of osteoporosis. A reduced parietal cell mass is a common feature in these conditions. AIM To study a possible relationship between chronic gastritis, parietal cell density of the oxyntic mucosa...

Objetivo: determinar la prevalencia de la infección por Helicobacter pylori en pacientes gastrectomizados por enfermedad no neoplásica, y que han desarrollado posteriormente cáncer gástrico. Material y métodos: estudio retrospectivo con reclutamiento de todos los pacientes con gastrectomía parcial por enfermedad péptica benigna que han sido sometidos a una exploración endoscópica entre 1995-200...

alkylhydroperoxide reductase (ahpc, the 26 kda antigen) is one of the abundant antioxidant enzymes in helicobacter pylori and seems to have a good potential for use in development of immunoassays to detect h. pylori infection in clinical specimens. this study aimed to investigate some properties of this antigen by the produced monoclonal antibodies. five established hybridoma cell lines secreti...

BACKGROUND Helicobacter species associated with human infection include Helicobacter pylori, Helicobacter heilmannii and Helicobacter felis among others. In this study we determined the prevalence of H. pylori and non-Helicobacter pylori organisms H. felis and H. heilmannii and analyzed the association between coinfection with these organisms and gastric pathology in patients presenting with dy...

OBJECTIVES To test the hypothesis that infection with Helicobacter pylori is associated with hyperemesis gravidarum. METHODS From November 1999 to February 2001, we enrolled 54 pregnant women with hyperemesis gravidarum and 53 asymptomatic pregnant women in a prospective study. Specific serum immunoglobulin G for Helicobacter pylori was assayed in the sera of the study group and compared with...

conclusions due to phenolic content, methanolic extract of m. piperita has moderate antibacterial and antifungal properties against the aforementioned gram positive and gram negative bacteria and fungi strains. materials and methods the methanolic extract was prepared by standard procedure, and total phenol, total flavonoid, and total anthocyanin content were determined using a spectrophotomete...
