Pulverized konjac glucomannan ameliorates oxazolone-induced colitis in mice

Kalopanaxsaponin B Ameliorates TNBS-Induced Colitis in Mice

The stem-bark of Kalopanax pictus (KP, family Araliaceae), of which main constituent is kalopanaxsaponin B, has been used for asthma, rhinitis, and arthritis in Chinese traditional medicine. To clarify anticolitic effect of KP, we examined anti-inflammatory effect of KP extract and kalopanaxsaponin B in lipopolysaccharide (LPS)-stimulated peritoneal macrophage and 2,4,6-trinitrobenzene sulfonic...

CCL25/CCR9 Interactions Regulate the Function of iNKT Cells in Oxazolone-Induced Colitis in Mice

BACKGROUND Natural killer T (NKT) cells share phenotypic and functional properties with both conventional natural killer cells and T cells. These cells might have an important role in the pathogenesis of ulcerative colitis (UC). The interaction of chemokine ligand 25 (CCL25) with chemokine receptor 9 (CCR9) is involved in gut-specific migration of leukocytes and induces regulatory T cells (Treg...

A simple and feasible approach to purify konjac glucomannan from konjac flour--temperature effect.

A simple one-step purification process was provided to extract KGM from KF by phase separation. The results showed that appropriate temperature control was a key factor and the products were inodorous, colourless and of high purity at the optimal temperature 68 °C. In this purification, soluble sugar and starch of extracted KGM were nearly clearly reduced and up to 95%, 80% (T68) of protein and...

Synergistic Interaction between Helix-Forming Polysaccharide and Konjac Glucomannan

Oxidized Konjac Glucomannan as a Paper Strength Agent

A paper strength agent is an important type of chemical additive used in the papermaking industry. In this work some new paper strengthening agent samples were obtained by treating konjac glucomannan with hydrogen peroxide under acidic conditions, and their effects on paper properties were studied. Results showed that oxidized konjac glucomannan (OKG) can improve the paper properties effectivel...
