BACKGROUND Helicobacter pylori infection is associated with diverse upper gastrointestinal diseases, such as peptic and duodenal ulcers as well as gastric cancer. Longstanding period of infection impose great risk of H. pylori-related gastric disease, based on the evidence that early childhood infection is responsible for ensuing atrophic gastritis and gastric cancer related to H. pylori infect...

Three polysaccharide fractions (TPS1, TPS2 and TPS3) with different molecular weights were obtained using ultra filtration membranes from crude tea polysaccharide (CTPS) extracted from abandoned lower grade tea leaves. Each fraction contained different contents of neutral sugar, uronic acid, protein, and total polyphenols. These differences provided basis for the antioxidant and free radical sc...

1. The polysaccharide fractions from each of five yeast-like fungi produce rapid, fatal anaphylactic shock in guinea pigs passively sensitized with antiserum from rabbits immunized against the killed organisms. 2. Cross-anaphylactic reactions with heterologous polysaccharide fractions are frequent. They parallel closely the cross-precipitin reactions, thus adding evidence in favor of the identi...

A water-soluble polysaccharide (BEBP) was extracted from Boletus edulis Bull using hot water extraction followed by ethanol precipitation. The polysaccharide BEBP was further purified by chromatography on a DEAE-cellulose column, giving three major polysaccharide fractions termed BEBP-1, BEBP-2 and BEBP-3. In the next experiment, the average molecular weight (Mw), IR and monosaccharide composit...

The Açaí (Acai) fruit is a popular nutritional supplement that purportedly enhances immune system function. These anecdotal claims are supported by limited studies describing immune responses to the Acai polyphenol fraction. Previously, we characterized γδ T cell responses to both polyphenol and polysaccharide fractions from several plant-derived nutritional supplements. Similar polyphenol and ...

Tinospora cordifolia is used in Ayurveda as "Rasayanas" to improve the immune system and the body resistance against infections. Polysaccharides are the main constituents which are considered to be responsible for immune enhancement. In this study, immunomodulatory activity of three polysaccharide enriched fractions was evaluated using the polymorphonuclear leukocyte function test. Sugar compos...

The polysaccharide fraction from Solanum nigrum Linne has been shown to have antitumor activity by enhancing the CD4+/CD8+ ratio of the T-lymphocyte subpopulation. In this study, we analyzed a polysaccharide extract of S. nigrum to determine its modulating effects on RAW 264.7 murine macrophage cells since macrophages play a key role in inducing both innate and adaptive immune responses. Crude ...

The study was conducted to investigate the free radical scavenging activities of polysaccharide fractions extracted from the fruiting body of medicinal mushroom, Ganoderma lucidum (Fr.) P. Karst (Reishi) using different antioxidant capacity assays. Four intracellular polysaccharide fractions were obtained by the hot-water extraction and precipitation with ethanol, by ammonium oxalate extraction...
