Protective effect of wild ginseng cambial meristematic cells on D-galactosamine-induced hepatotoxicity in rats

Panax ginseng has a wide range of biological activities including anti-inflammatory, antioxidant, and immunomodulatory functions. Wild ginseng cambial meristematic cells (CMCs) were obtained from P. ginseng cambium. This study examined the protective mechanism of wild ginseng CMCs against D-galactosamine (GalN)-induced liver injury. GalN, a well-known hepatotoxicant, causes severe hepatocellular inflammatory damage and clinical features similar to those of human viral hepatitis in experimental animals.

A UPLC/MS-based metabolomics investigation of the protective effect of ginsenosides Rg1 and Rg2 in mice with Alzheimer’s disease

Alzheimer’s disease (AD) is a progressive brain disease, for which there is no effective drug therapy at present. Ginsenoside Rg1 (G-Rg1) and Ginsenoside Rg2 (G-Rg2) have been reported to alleviate memory deterioration. However, the mechanism of their anti-AD effect hasn’t yet been clearly elucidated.

Up-regulation of heme oxygenase-1 by ginsenoside Ro attenuates lipopolysaccharide-induced inflammation in macrophage cells

The beneficial effects of ginsenoside species have been well demonstrated in a number of studies. However, the function of ginsenoside Ro (GRo), an oleanane-type saponin, has not been sufficiently investigated. Thus, the aim of the present study was to investigate the anti-inflammatory effects of GRo in vitro using the Raw 264.7 mouse macrophage cell line treated with lipopolysaccharide (LPS), and to clarify the possible mechanism of GRo involving heme oxygenase-1 (HO-1), which itself plays a critical role in self-defense in the presence of inflammatory stress.

Inhibitory effects of [Ca] mobilization by total saponin from Korean red ginseng phosphorylation of PKA catalytic subunit and in human platelets

Intracellular Ca2+ ([Ca2+]i) is platelet aggregation-inducing molecule. Therefore, understanding the inhibitory mechanism of [Ca2+]i mobilization is very important to evaluate the antiplatelet effect of a substance. This study was carried out to understand the Ca2+-antagonistic effect of total saponin from Korean red ginseng (KRG-TS).

Photosynthesis rates, growth and ginsenoside contents of 2-year-old grown at different light transmission rates in a greenhouse

Ginseng is a semi-shade perennial plant cultivated at sloping, sun-shading area in Korea. Recently, due to air-environmental stress and various fungal diseases, greenhouse cultivation has been suggested as an alternative. However, the optimal light transmission rate (LTR) in the greenhouse has not been established.
