In this study, we investigated the effects of Ginseng Radix (G), Rehmanniae Radix (R), and Fermented red-ginseng extracts (FRG) on cognitive function in scopolamine-induced memory-impaired mice. We measured the effects of G, R, and FRG on the improvement of memory and cognition via behavior analysis. In addition, we measured the acetylcholinesterase (AChE) activity in the hippocampus of each group of mice. The expression of β-amyloid, Tau, and BDNF in the brain tissues were observed through immunohistochemical staining. Ginseng Radix (G) and Fermented red-ginseng (FRG) have effectively improved cognitive function in the water maze test. Ginseng Radix (G), Rehmanniae Radix (R), and Fermented red-ginseng (FRG) have improved the willingness of mice to explore the new environment, as confirmed by Y maze test. In addition, immunohistochemical staining revealed that Ginseng Radix (G) decreased the expression of β-amyloid and Tau in the hippocampus. In addition, fermented red-ginseng (FRG) increased the expression of BDNF. Ginseng Radix (G), Rehmanniae Radix (R), and Fermented red-ginseng (FRG) have decreased the concentration of acetylcholinesterase in the hippocampus as compared with the control group of mice. In conclusion, Ginseng Radix (G), Rehmanniae Radix (R), and Fermented red-ginseng (FRG) are considered to have the potential for development as candidate drugs to control the progression of Alzheimer's disease (AD).

Objectives This study was designed to investigate the effects of fermented soybean upon anti-inflammation, cytotoxicity, antioxidant and intestinal mucous membrane permeability by measuring the cell viability, NO (nitric oxide) production, DPPH, Polyphenol, HRP and TEER in cells like Raw 264.7 and HCT 116 using fermented soybean. Methods Raw 264.7 cell and HCT 166 cell were used in this study. And fermented soybean powders were used for the experimental group and soybean powders for the control group. There was inflammation response upon using lipopolysaccharide(LPS). Fermented soybean powders and soybean powders were in a respectively different dose added to the cells with LPS. MTT assay, NO, DPPH and Polyphenol measurement, TEER, HRP were conducted for each cell. The results of this study were presented in mean and standard deviation. Results 1. In Raw 254.7 cells added with $100{\mu}l/ml$ unfermented soybean powders, 104.95% higher than 62.59% was measured. In Raw 254.7 cells added with $100{\mu}l/ml$ fermented soybean powders, there was 74.90% measured higher than 62.59%, which was a significant result. 2. By a gradual increase of unfermented soybean powders like $0.1{\mu}l/ml$, $1.0{\mu}l/ml$, $10{\mu}l/ml$, $100{\mu}l/ml$, the measured NO were also gradually decreased $53.12{\mu}M$, $47.57{\mu}M$, $37.02{\mu}M$, $28.16{\mu}M$. In case of cells added with fermented soybean powders, $43.95{\mu}M$ NO was measured in $0.1{\mu}l/ml$ which is significant, and in other cases, mostly measured over$ 56.72{\mu}M$. 3. It was inferred that fermented soybean powders have anti-inflammatory effects of maintaining intestinal mucous membrane permeability because the measured values of cells in both groups were all higher than $133.62{\Omega}$ measured of cells added with only LPS. And measured values of cells in both groups were all lower than 2.26 measured of cells added with only LPS. 4. In case of experiment DPPH and polyphenol measurement, fermented group was all higher than unfermented group. Conclusion From the results of conducting MTT assay, NO measurement, and TEER, HRP by using cells Raw 264.7 and HCT-116, even though there was no significance in the correlation between cytotoxicity, anti-inflammatory effects, both unfermented soybean powders and fermented soybean powders were shown to have intestinal mucous membrane permeability improvement effects. This effects could be applicable for autoimmune diseases, chronic inflammatory diseases and so additional studies are expected in the future. From the results of conducting DPPH, Polyphenol measurement, Fermented soybean may be useful as potential antioxidant.

The purpose of this study is to investigate the effect of a mixture of fermented Artemisiae Argi Folium and fermented Sophorae Radix (FAS) on hydrogen peroxide production within mouse macrophage Raw 264.7 with ethanol (EtOH) and nicotine. Artemisiae Argi Folium is known to have the antibacterial, immune-enhancing properties. And Sophorae Radix is also known to have the antibacterial, anti-inflammatory, anti-allergic properties. EtOH and nicotine are the ones of toxicants which could impair immunocytes like macrophage. EtOH and nicotine reduce the intracellular production of hydrogen peroxide ($H_2O_2$) of Raw 264.7. FAS increased the production of hydrogen peroxide reduced by EtOH and nicotine within Raw 264.7. These results indicate that FAS could restore the immuno-activity of macrophage impaired by EtOH and nicotine.

Objectives: This study was performed to evaluate the effects of fermented Samjung-hwan (SJH) extracts on weight, serum lipids and blood glucose. Methods: SJH was fermented using three different probiotic bacterial strains (Lactobacillus plantarum [LP], Leuconostoc mesenteroides [LM], Bifidobacterium longum [BL]) separately. Thirty-six rats were divided into normal, control (high fat diet), SJH-UF (high fat diet+unfermented SJH 200 mg/kg), SJH-LP (high fat diet+LP fermented SJH 200 mg/kg), SJH-LM (high fat diet+LM fermented SJH 200 mg/kg) and SJH-BL (high fat diet+BL fermented SJH 200 mg/kg). For 8 weeks later, we examined body weight, total cholesterol, high-density lipoprotein (HDL)-cholesterol and blood glucose. Results: The control group showed significantly increased weight gain compared with normal group and SJH-LP and BL groups had less weight gain than control group, significantly. In the lipid serum tests, control group showed significantly increased total cholesterol levels compared with normal group and only SJH-LP represented decreased total cholesterol levels compared with control group. However there was no significant change in the HDL-cholesteol levels. In the blood glucose tests, that of control group significantly incereased more than that of normal group, SJH-BL showed significantly decreased blood glucose levels compared with control group. Conclusions: SJH-LP, SJH-BL showed weight control effect, SJH-LP decreased TC and SJH-BL reduced blood glucose.
