This study was conducted to investigate the effects of Acanthopanax senticosus extracts(ASE) on alcohol administered mice. The administration of Acanthopanax senticosus extracts(60㎎/㎏) had beneficial actions toward alcohol degradation in acute alcohol treated mice. In the acute alcohol degradation experiment, serum alcohol concentration were lower 3 and 6 hours after taking ethanol(5g/㎏) in ASE treated mice. The oral administration of ASE showed decreased gastric mucous membrane damage produced in ethanol treated mice. In addition, intraperitoneal(i.p.) administration of ASE showed anti-inflammatory effects in inhibition tests of vascular permeability produced by acetic acid. ASE also reduced concentrations of nitric oxide(NO), tumor necrosis alpha(TNF)-α and interleukin(IL)-6 in macrophages that were activated by LPS. These results demonstrate that Acanthopanax senticosus extracts possesses the potential to stimulate alcohol degradation and inhibit inflammatory effects in mice.

This study was demonstrated that the fermentation of gingseng increases its biological activities,by comparing the anti-tumor and immunostimulating activities of fermented gingseng extracts (FginE) with those of non-fermented ginseng (GinE). In the experimental lung metastasis of colon26-M3.1 carcinoma, the intraperitoneal (i.p.) or peroral (p.o.) administration of FginE showed stronger anti-tumor metastatic activities than those of GinE. When stimulating 2 kinds of extract on macrophages,FginE was shown to have a higher production of interleukin (IL)-12 than GinE. In addition, treatment with FginE induced tumoricidal activity of peritoneal macrophages against colon26-M3.1 cells. When Peyer's patch was cocultured with FginE, the proliferation of these cells and granulocyte macrophage-colony stimulating factor (GMCSF)production were induced. In an assay for natural killer (NK) cell activity, an i.p. administration of FginE significantly augmented NK cytotoxicity against Yac-1tumor cells. Fermented ginseng extracts promotes antitumor activities to inhibit tumor metastasis, and its antitumor effects are associated with the enhancement of systemic as well as mucosal immune systems.
