Background: Understanding what causes changes in the flux of free fatty acids (FFA) is important to elucidate the etiology of metabolic syndrome. The first aim of this study was to test whether or not hormones and the autonomic nervous system influence blood FFA levels. A secondary aim was to test by means of a multiple group path analysis whether the consumption of fermented red ginseng (FRG; Panax ginseng) would influence those causal relationships. Methods: Ninety-three postmenopausal women (age 50e73 yr) were randomly divided into two groups. One group (44 women; age, $58.4{\pm}5.9yr$; body mass index, $3.6{\pm}2.5kg/m^2$) was supplied place capsules and the other group (49 women, age $58.4{\pm}5.5yr$; body mass index, $22.9{\pm}2.4kg/m^2$) was supplied FRG capsules. Both prior to and after the study (2 wk), blood samples were collected from the participants and several blood variables were measured and analyzed. Results: Squared multiple correlations of FFA were 0.699 in the placebo group and 0.707 in the FRG group. The unstandardized estimate of estradiol (E2) for FFA was 0.824 in both groups. Conclusion: The path coefficients of cortisol and the branchial pulse for FFA were significantly different between the FRG group and the placebo group.

The qualities of ginseng leaf teas prepared by six different processing methods were evaluated to develop the leaf tea. The leaf tea prepared by fermentation at $30^{\circ}C$ showed the highest in the ratio of 30 min water extracts to the total extractable matters. This ratio was followed in decreasing order by the heat dried tea and the one fermented at $25^{\circ}C$. The yellow, orange and red color intensities of water extracts were the highest in the tea prepared by toasting method followed by teas fermented at $30^{\circ}C\:and\:25^{\circ}C$. The amount of saponins extracted with boiling water was the highest in the tea fermented at $30^{\circ}C$ among teas investigated. This tea was also most acceptable in sensory evaluation by the flavour profile method.

Background: To increase the pharmacological effects of red ginseng (RG, the steamed root of Panax ginseng Meyer), RG products modified by heat process or fermentation have been developed. However, the antiallergic effects of RG and modified/fermented RG have not been simultaneously examined. Therefore, we examined the allergic rhinitis (AR)-inhibitory effects of water-extracted RG (wRG), 50% ethanol-extracted RG (eRG), and bifidobacteria-fermented eRG (fRG) in vivo. Methods: RBL-2H3 cells were stimulated with phorbol 12-myristate-13-acetate/A23187. Mice with AR were prepared by treatment with ovalbumin. Allergic markers IgE, tumor necrosis factor-${\alpha}$, interleukin (IL)-4, and IL-5 were assayed in the blood, bronchoalveolar lavage fluid, nasal mucosa, and colon using enzyme-linked immunosorbent assay. Mast cells, eosinophils, and Th2 cell populations were assayed using a flow cytometer. Results: RG products potently inhibited IL-4 expression in phorbol 12-myristate-13-acetate/A23187-stimulated RBL-2H3 cells. Of tested RG products, fRG most potently inhibited IL-4 expression. RG products also alleviated ovalbumin-induced AR in mice. Of these, fRG most potently reduced nasal allergy symptoms and blood IgE levels. fRG treatment also reduced IL-4 and IL-5 levels in bronchoalveolar lavage fluid, nasal mucosa, and reduced mast cells, eosinophils, and Th2 cell populations. Furthermore, treatment with fRG reduced IL-4, IL-5, and IL-13 levels in the colon and restored ovalbumin-suppressed Bacteroidetes and Actinobacteria populations and ovalbumin-induced Firmicutes population in gut microbiota. Treatment with ginsenoside Rd significantly alleviated ovalbumin-induced AR in mice. Conclusion: fRG and ginsenoside Rd may alleviate AR by suppressing IgE, IL-4, IL-5, and IL-13 expression and restoring the composition of gut microbiota.

For the utilization of Korean ginseng (Panax ginseng C.A. Meyer) in the functional drink, we prepared the fermented Korean ginseng with mushroom mycelia (Ganoderma lucidum; WG-GL, Hericium erinaceum; WG-HE and Phellinus linteus; WG-PL) by solid culture. A proximate analysis showed that the fermented Korean ginseng contained significantly more crude fat (4.66$\sim$12.02%) than Korean ginseng (WG, 1.61%) whereas crude protein content of WG (13.64%) was higher value than those of the ferments (7.60$\sim$12.57%). When we also evaluated effects of the fermented Korean ginseng on the mitogenic activity, hot-water extract from WG-PL was significantly higher than those of WG or mycelia only fermentation (GL, HE and PL) as analyzed by IL-2 production (1.64-fold of the saline control) and proliferation of splenocytes (1.47-fold). In addition, the lysosomal phosphatase activity (WG-HE; 1.32-fold) and NO/TNF-$\alpha$ production (WG-HE; 2.27-fold of the saline control at 50 ${\mu}g$/mL, WG-PL; 3.56-fold, respectively) from macrophage in the presence of the fermented Korean ginseng were higher than those of WG or mycelia fermentation. These results indicate that hot-water extracts from the fermented Korean ginseng with mushroom mycelia by solid culture contain chemical ingredients different from the Korean ginseng, and that it might provide beneficial immunostimulating activity.

In this study, Lactobacillus brevis SM61 from traditional Kimchi was used for fermentation of aqueous extract of P. brevitarsis larva and mountain ginseng. As measured by MTT assay, aqueous extract of P. brevitarsis larva and fermented mixture of aqueous extract and mountain ginseng did not show specific cellular toxicity in RAW264.7 cells until a concentration of $5-1000{\mu}g/mL$. The polyphenol contents was highest in the fermented mixture of aqueous extract and mountain ginseng. DPPH radical scavenging activity was stronger in the fermented mixture of aqueous extract and mountain ginseng than the aqueous extract. Also, antibacterial activity was tested against E. coli, L. monocytogenes and S. aureus. The fermented mixture of aqueous extract and mountain ginseng showed antibacterial activity against the tested bacteria. Therefore, L. brevis SM61 as a starter might be used to improve functionality of P. brevitarsis larva.

This study was performed to elucidate the antioxidative and antiaging activities of mixed rates 2:6:2(262), 6:2:2(622) and 4:4:2(442) of fermented soybean, fermented rice bran, fermented red ginseng based on the comparision with their separate results of our three previous studies. The antioxidative and antiaging effects of 262, 622 and 442 mixed ratios were evaluated by the determination of superoxide radical scavenging activities, hydroxy radical scavenging activities, linoleic acid inhibition activtiy, elastin synthesis activity, and cell viability of B16F10. The material of 442 ratio showed the higher effects than those of 262 and 622 ratios, and presented the higher effect than the separate material of red ginseng in the antioxidative and antiaging activities. Therefore, this study suggested that the material of 442 ratio in the production of red gineng-containing cosmetics could be preferred as a useful cosmetic ingredient for antioxidation and antiaging.

This study was investigating the anti-obesity effects of diets with a mixture of cheese, red ginseng and fermented mature fruit of Rubus coreanus Miquel. We fed the experimental diets (SC5, SC10) supplemented with 5% or 10% cheese containing of fermented mixture, then orally administered the extract of fermented mixture (RB100, RB300) at a concentration of 100 or 300 mg/kg body weight to SD rats with high fat diet (HFD). The results were as follows: Sample cheese groups decreased visceral fat mass and adipocyte size of stomach compared to that of HFD group. Additionally, lipid droplets of liver in sample cheese groups were smaller than that in HFD group. The serum triglyceride (TG), total cholesterol (tChol), glucose, leptin, and insulin levels in sample cheese group were lower than that in HFD group. But, the serum adiponectin and HDL-cholesterol (cHDL) levels were higher than that in HFD group. These results suggest that fermentation of red ginseng and Rubus coreanus mixed with cheese might be helpful in preventing obesity in high fat diet-fed rats.

The aim of this study was to compare the fermentation characteristics of tissue cultured mountain ginseng, extruded tissue cultured mountain ginseng, and root hair of red ginseng. Also, pH, acidity, brix, reducing sugar, total sugar, and alcohol were analyzed. The extrusion conditions were barrel temperature of 110 and $140^{\circ}C$ and moisture content of 25 and 35%. Fermentation temperature was $27^{\circ}C$ for 15 days and the cultivation was fixed with Saccharomyces cerevisiae, Aspergillus usamii, and Rhizopus japonicus. The results showed that pH, brix, reducing sugar content, and total sugar content of fermented broths were decreased after 5 days and then maintained steadily for the following 10 days. Acidity of final fermented broths were 1.12% (root hair of red ginseng), 1.19% (tissue cultured mountain ginseng), and $0.97{\sim}1.02%$ (extruded tissue cultured mountain ginseng), respectively. Alcohol content of final fermented broths were 3.82% (root hair of red ginseng), 0.91% (tissue cultured mountain ginseng), and $1.86{\sim}2.18%$ (extruded tissue cultured mountain ginseng). The fermentation efficiency of extruded tissue cultured mountain ginseng (barrel temperature $140^{\circ}C$, moisture content 25%) were the highest. In conclusion, the fermentation efficiency was increased by extrusion process.
