In the present study, the anti-cancer effects of ginseng fermented with Phellinus linteus (GFPL) extract were examined through in vitro and in vivo assays. GFPL was produced by co-cultivating ginseng and Phellinus linteus together. Ginsenoside Rg3, Rh1 and Rh2 are important mediators of anti-angiogenesis and their levels in GFPL were enriched 24, 19 and 16 times, respectively, more than that of ginseng itself through the fermentation. GFPL exhibited distinct anti-cancer effects, including growth inhibition of the human lung carcinoma cell line A549, and promotion of immune activation by stimulating nitric oxide (NO) production in Raw 264.7 cells. Further evidence supporting anti-cancer effects of GFPL was its significant prolongment of the survival of B16F10 cancer cell-implanted mice. These results suggest that the GFPL may be a candidate for cancer prevention and treatment through immune activation and anti-angiogenic effects by enriching Rg3, Rh1 and Rh2.

In order to test the functionality of Panax ginseng thioredoxin 1 (PgTRX1) isolated from fermented wild ginseng roots, a transient effect on physiological activity were performed over a short time frame using the Agrobacterium infiltration technique. The PgTRX1 gene isolated from fermented wild ginseng was confirmed to have a size of 579 bp, and the expression of PgTRX1 was the highest in the sample after 6 h of fermentation. As a result of constructing this gene and confirming the infiltration reaction mediated by Agrobacterium in tobacco leaves, it was found that the expression of the NbHSR203j gene was also induced as PgTRX1 expression increased. As a result of measuring the biological activity of the infiltration samples, the total phenol content increased by 35.45±1.84 to 49.01±1.84 ㎍ GAE/mL compared to the control, and the total flavonoid amount of 9.52±0.41 to 9.82±0.25 ㎍ QE/mL was slightly high. From these results, Agrobacterium-mediated PgTRX1 appears to be related to the hypersensitive response induction mechanism of plants and the production of secondary metabolites such as phenolic substances.

Red ginseng is known to have many beneficial effects. Cisplatin, an effective antineoplastic drug, can cause many side effects like irreversible sensorineural hearing loss and serious tinnitus in humans. This study is aimed to reduce a cisplatin's side effect, nephrotoxicity by fermentated korean red ginseng. Korea ginseng was produced by steaming and dring and fermentation. And mice were divided into 4 groups- (A) normal mice, (B) Vehicle treated cisplatin mice, (C) RG0F0-treated cisplatin mice, (D) RG8F3-treated cisplatin mice. C and D groups were feed each material 200 mg/kg/day during 4 days. And cisplatin 20 mg/kg injected to B, C, and D groups as abdominal injection. After 24 h, blood sample was collected. The kidneys were harvested for histological, immuno histochemical and western blot analysis. 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical scavenging activity was depended on steaming hours. RG0F0 and RG8F3 (ginseng-8 h steamed and fermented by Saccharomyces cerevisiae) were showed antioxidants effect in DPPH and ABTS radical scavenging activity. Component amounts according to steaming hours. 8 h steamed red ginseng had the most ingredients of ginsenoside. Treatments with RG8F3 reduced cisplatin-induced nephrotoxicity in the mice resulting in increase of GSH and decrease of ROS, BUN, creatinine, and inflammatory mediators. This result seems to be involved with the restriction of the inflammation in the kidney. Therefore, fermented red ginseng might have therapeutic efficacy in reduce kidney injury induced by cisplatin treatment.

Panax ginseng C.A. Meyer has been used as a traditional medicinal ingredient and the ginseng flower-buds also proved to have good medicinal properties. In this study, in order to enhance immune activities of ginseng flower-bud, the ginseng flower-bud extract was being fermented by Bacillus subtilis KCTC 1022 (BS), Lactobacillus plantarum KCTC3 and Saccharomyces cerevisiae strain CHY1011 (SC). Mice were orally administered daily for two weeks at two different concentrations (100 and 200 mg/kg B.W.). Treatment samples were water extracts of ginseng flower-buds (FD), water extracts of fermented ginseng flower-buds (FM) and controls for saline solution. Cytokine production (IL-6, TNF-${\alpha}$) either stimulated with LPS or not stimulated with LPS was detected by the ELISA assay when using the cytokine kit. Cytokine was statistically increased at supplemented groups with LPS in both the 100 and the 200 mg/kg B.W. and treatment with FM significantly decreased the LPS-induced TNF-${\alpha}$ and IL-6 production more than the treatment with FD. The results of this study may suggest that supplementation with FM increases the immune function by regulating cytokine production capacity for activated macrophages.

This study was conducted to investigate the effect of fresh ginseng on the physicochemical, microbiological and sensory properties of Seukbakjee during 45 days of fermentation. Seukbakjee with various levels(0, 2, 4, 6%) of fresh ginseng were fermented at $4^{\circ}$. During fermentation, the pH values were lowered in all Seukbakjee samples, however, those with fresh ginseng were a little higher than control Seukbakjee. Acidity increased continuously during the entire fermentation, in which those of added fresh ginseng increased less than control. As the concentration of fresh ginseng increased, the pH of Seukbakjee were increased. Saltiness was maintained at 1.37~2.62% levels during the whole fermentation. The degree of degradation of reducing sugar and free sugar was much delayed in Seukbakjee added with fresh ginseng. Total vitamin C content of Seukbakjee with fresh ginseng was higher than that of Seukbakjee without fresh ginseng. The number of total bacteria and lactic acid bacteria in Seukbakjee with fresh ginseng was higher than control during the entire fermentation period. In sensory evalution, Seukbakjee with 4% fresh ginseng was the best for taste and flavor. Seukbakjee with 2% fresh ginseng was the best for texture and overall acceptability. Above results suggest that the addition of fresh ginseng improves the quality of Seukbakjee.

Panax ginseng C. A. Meyer has been one of the most highly recognized medicinal herbs in the Orient. Previous experiments have demonstrated that $Rg_3,\;and\;Rg_5$ statistically significantly decreased the incidence of benzo(a)pyrene-induced mouse lung tumor, $Rh_2$ showed tendency of decrease and $Rh_1$ showed no effect. It was, therefore, concluded that $Rg_3,\;Rg_5\;and\;Rh_2$ are active cancer chemopreventive components in red ginseng and they either singularly or synergistically act in the prevention of cancer. This study was undertaken to compare the cancer chemopreventive effects of $Rg_3,\;Rg_5\;and\;Rh_2$(purity: more than $60\%$) isolated from fermented ginseng extract and BST fermented ginseng with fortified ginsenoside $Rg_3\;and\;Rh_2$. The cancer chemopreventive effects were investigated in experimental groups treated with benzo(a)pyrene(BP) with ginsenoside $Rg_3,\;Rg_5\;Rh_2\;or\;BST$ at three doses of $50^{\circ}C/ml,\;100^{\circ}C/ml\;and\;200^{\circ}C/ml$ When mice given with $50^{\circ}C/ml$ concentration of ginsenoside $Rg_3$ combined with BP for 6 weeks after BP administration, $Rg_3\;showed\;60\%$ of lung tumor incidence, where as $100^{\circ}C/ml\;and\;200^{\circ}C/ml\;of\;Rg_3$ combined with BP groups had significant decrease of incidence $(40.0\%)$ respectively, with the inhibition rate being $35.5\%.$ While the tumor incidence was not decreased in the group treated with BP and 50 of $Rg_5,$ the incidence was $34.0\%\;and\;32.0\%$ in the group treated with BP and 100 and 200 of $Rg_5$, respectively. These incidences were significantly less than the group treated with BP alone, with the inhibition rate being $45.2\%\;and\;48.4\%,$ respectively. On the other hand, in the group treated with BP and 50 of ginsenoside $Rh_2,$ the tumor incidence was not decreased. However, the incidence was $40.0\%\;and\;38.8\%$ in the experimental treated with BP and 100 and 200 of $Rh_2,$ respectively, with the inhibition rate being $45.2\%\;and\;48.4\%,$ respectively. In addition, the incidence showed the tendency to decrease in the experimental group treated with BP and 50 of BST which contained $16.2\%\;of\;Rh_2,\;15.4\%\;of\;Rg_3\;and\;2.5%\;of\;Rg_5.$ The tumor incidence was $54.0\%$ in this group. In the group treated with 100 and 200 of EST, the incidence was $34.0\%\;and\;30.0\%,$ respectively, the incidences significantly being lower than the group treated with BP alone, with the inhibiting rate being $45.2\%\;and\;51.6\%,$ respectively. The results of this study strongly suggested that ginsenoside $Rg_3,\;Rg_5\;and\;Rh_2$ are the active components of red ginseng having a cancer chemopreventive activity and $Rg_5$ is the strongest cancer chempopreventive among them. On the other hand, the results demonstrating that the incidence of lung tumor was more markedly reduced by BST fermented ginseng with fortified ginsenoside $Rh_2\;or\;Rg_3$ compared to the single component alone, suggest that the combination of these components may remarkablely improve the cancer preventive effect

Korean ginseng, which contains ginsenosides and polysaccharides as its main constituents, is orally administered to humans. Ginsenosides and polysaccharides are not easily absorbed by the body through the intestines due to their hydrophilicity. Therefore, these constituents which include ginsenosides Rb1, Rb2, and Rc, inevitably come into contact with intestinal microflora in the alimentary tract and can be metabolized by intestinal microflora. Since most of the metabolites such as compound K and protopanaxatriol are nonpolar compared to the parental components, these metabolites are easily absorbed from the gastrointestinal tract. The absorbed metabolites may express pharmacological actions, such as antitumor, antidiabetic, anti-inflammatory, anti-allergic, and neuroprotective effects. However, the activities that metabolize these constituents to bioactive compounds differ significantly between individuals because all individuals possess characteristic indigenous strains of intestinal bacteria. Recently, ginseng has been fermented with enzymes or microbes to develop ginsengs that contain these metabolites. However, before using these enzymes and probiotics, their safety and biotransforming activity should be assessed. Intestinal microflora play an important role in the pharmacological action of orally administered ginseng.

Red ginseng marc is a by-product of Korean red ginseng (panax ginseng CA Meyer) and contains ginsenoside which has pharmacological effects. The Korean red ginseng marc was fermented with Bacillus subtilis (RGMB). This study was carried out to investigate the RGMB effect on swine immunity. The variation of ginsenoside depending on the RGMB fermentation time was analyzed. Swine (Landrace${\times}$Yorkshire) were divided into control group (basic diet) and RGMB group (RGMB 1% diet). One percent RGMB was fed to the RGMB group for 28 days. The biochemical parameters, cytokine and immunoglobulin were analyzed. For 48 hours of fermentation on RGMB, ginsenoside Rb1 had increased 180.94%, Rg3 235.85%. Rg1 wasn't detected before fermentation, but was detected after 48 hours of fermentation. The RGMB had effect of deceasing initial AST concentration $79.33{\pm}12.85U/L$ to $54.00{\pm}14.46U/L$ in final and was significantly lower (P<0.05) than control in final. In final RGMB had significantly lower (P<0.05) ALT concentration of $48.57{\pm}8.26U/L$ comparing with control group of $65.43{\pm}10.31U/L$. RGMB had the effect of significantly decreasing (P<0.05) $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ concentration of $2.44{\pm}1.31ng/mL$, $0.71{\pm}0.36ng/mL$ and $0.51{\pm}0.21ng/mL$. The IgA concentration had significantly increased (P<0.05) in RGMB group of $0.56{\pm}0.06mg/mL$ in final. These results demonstrate that RGMB has effect of increasing immunity and practicable to use as feed additives on swine.

Fermented red ginseng (FRG) was prepared by inoculating 0.1% Lactobacillus fermentum NUC-C1 and fermenting them at $40^{\circ}C$ for 12 hours. The ginsenoside contents of FRG were increased compared with those of red ginseng (RG). Moreover, the levels of the ginsenosides Rg2, Rg3, and Rh2 in FRG increased significantly. In an oral glucose tolerance test (OGTT), blood glucose levels were lower in animals fed with RG and FRG extracts than in normal controls. In particular, FRG extracts in OGTT were superior to RG extracts. The antidiabetic effects of FRG in streptozotocin (STZ)-induced diabetic rats were investigated. Rats were divided into four groups: normal control, diabetes mellitus (DM), FRG administered at 100 mg/kg, and FRG administered at 200 mg/kg groups. FRG extracts were orally administered to each treatment group for 3 weeks, and blood glucose, insulin, and lipid levels of each group were determined. Orally administered FRG extracts significantly reduced blood glucose levels and increased plasma insulin levels in diabetic rats. Additionally, the activities of disaccharidases, including sucrase, lactase, and maltase, were decreased significantly in the FRG groups. FRG groups also had reduced triglyceride and total cholesterol levels, compared with the DM group. These results suggest that FRG may have antidiabetic effects in STZ-induced diabetic rats.
