OBJECTIVE The primary challenge for tissue engineering is to develop a vascular supply that can support the metabolic needs of the engineered tissues in an extracellular matrix. In this study, the feasibility of using a natural compound, ginsenoside Re, isolated from Panax ginseng in stimulating

Detection and quantification of ginsenoside Re in ginseng samples by a chromatographic immunostaining method using monoclonal antibody against ginsenoside Re.

Numai utilizatorii înregistrați pot traduce articole

A chromatographic immunostaining method has been developed for the determination of ginsenoside Re (G-Re) in ginseng samples on a polyethersulphone (PES) membrane. G-Re standard and the extracts of ginseng roots were applied to a PES membrane and developed by methanol-water-acetic acid (45:55:1, by

Development of a secondary antibody thio-functionalized microcantilever immunosensor and an ELISA for measuring ginsenoside Re content in the herb ginseng.

This study was undertaken to evaluate the effect of ginsenoside-Re (Gin-Re) isolated from roots of Panax ginseng on carrageenan-induced paw and TPA-induced skin inflammations in experimental mice. Moreover, to confirm further the anti-inflammatory activities of Gin-Re, LPS-induced macrophage

Electrophysiological effects of ginseng and ginsenoside Re in guinea pig ventricular myocytes.

Numai utilizatorii înregistrați pot traduce articole

Panax ginseng is a folk medicine with various cardiovascular actions; however, its underlying mechanisms of action are not well known. In the present study, we examined the effects of ginseng and its main component, ginsenoside Re, on action potentials and membrane currents recorded from isolated

Inhibitory effects of ginsenoside re isolated from ginseng berry on histamine and cytokine release in human mast cells and human alveolar epithelial cells.

Numai utilizatorii înregistrați pot traduce articole

The berry of Panax ginseng significantly inhibited the histamine releases at the concentration of 30 μg/mL (p<0.05) and 10 μg/mL (p<0.01). The ginsenoside Re from ginseng berry was found out to have a potent effect in the experiment of histamin and cytokine release.

Anticarcinogenic effects of products of heat-processed ginsenoside Re, a major constituent of ginseng berry, on human gastric cancer cells.

Ginsenoside Re is a triol type triterpene glycoside and is abundantly present in ginseng berry. In the present study, we verified that ginsenoside Re can be transformed into less-polar ginsenosides, namely, Rg2, Rg6, and F4, by heat-processing. The products of heat-processed ginsenoside Re inhibited
