The effects of White Ginseng and Fermented Ginseng on liver damage induced by $^{60}Co$ r-ray irradiation were investigated. To one group of ICR male mice were given in White Ginseng(150 mg/kg/day for 7days, orally) before 5Gy(1.01Gy/min) dose of $^{60}Co$ r-ray irradiation. To another group were given in Fermented Ginseng (150 mg/kg/day for 7days, orally)before 5Gy(1.01Gy/min)dose of $^{60}Co$ r-ray irradiation was investigated. Radiation irradiation group were given with saline(0.1 ml) and 5Gy. Contrast group were given with saline(0.1 ml). The levels of $H_2O_2$, catalase and MDA in liver tissue were measured. In Fermented Ginseng (FG+Rad) group and white Ginseng(WG+Rad) group than irradiation group(Rad), the catalase level were significantly increased, and the catalase levels were appeaWhite at radiation protection. It was significantly decreased to MDA and $H_2O_2$ level to Fermented Ginseng (FG+Rad) group and white Ginseng(WG+Rad) group than irradiation group(Rad). Therefore, Fermented Ginseng and white Ginseng were very excellent protector on radiation of liver in mice.

Citrus unshiu (C. unshiu) Markovich were dried peel of mandarin orange, of which fresh fruit was one of the famous foods in Korea and Eastern Asia. In the oriental medicine, C. unshiu peel was known to have a diuretic effect and to strengthen spleen function. Recently, natural flavonoids of C. unshiu peel have been investigated. In this study, C. unshiu peel extract containing flavonoid-glycosides was cultured with Schizophyllum commune (S. commune) mycelia producing ${\beta}$-glu- cosidase and its biological activities were investigated. ${\beta}$-glucosidase of S. commune mycelia converted the flavonoid-glycosides (rutin and hesperidin) into aglycones (naringenin and hesperetin). Fermented C. unshiu peel extract compounds were analyzed by HPLC system. The photoprotective potential of fermented C. unshiu peel extract was tested in human dermal fibroblasts (HDFs) exposed to UVA. Fermented C. unshiu peel extract extract also showed notable in vitro anti-inflammatory effect on cellular systems generating cyclooxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX) metabolites. Also, UVB-induced production of interleukin-$1{\alpha}$ in human HaCaT cells was reduced in a dose-dependent manner by treatment with fermented C. unshiu peel extract. These results suggest that fermented C. unshiu peel extract may mitigate the effects of photoaging in skin by reducing UV-induced adverse skin reaction.

Nutritional concentrations by chemical analyses of mushroom fermented milk were protein 2.87%, fat 0.09%, carbohydrates 6.0%, dietary fiber 0.3%, lactose 2.01%, sucrose 1.23%, calcium 95.9 mg/100 g and iron 0.08 mg/100 g. The present study was undertaken to investigate the hypoglycemic effects of the equal volume of either water (streptozotocin (STZ)rontrol rats), mushrooms water-extract (STZ-extrart fed rats), mushroom fermented milk product (STZ-mushroom yogurt fed rats) or mushroom fermented milk supernatant (STZ-supernatant fed rats) (10%, v/w), in STZ-induced diabetic rats for 3 week period. The mushroom fermented milk given to the STZ-diabetic rats decreased the blood glucose significantly and increased the blood insulin, compared with the STZ-control rats. The supernatant and mushroom water extract also slightly retarded the development of hyperglycemia in the STZ-diabetic rats. Taken together the results, the mushroom yogurt may have a potential for the hypoglycemic effect in the STZ-diabetic rats.

This study was carried out to investigate the hair protection effect of fermented black soybean extracts. The morphological characteristics, tensile strength and constitutional changes of the hair were analyzed and compared when the hair was chemically oxidized and then treated with fermented black soybean extract. As a result, treatment of oxidizing agent on virgin hair caused damage on the cuticle layer of the epidermis and decreased in tensile strength of hair from $14.32{\pm}0.83g/cm^2$ to $12.32{\pm}0.79g/cm^2$. FT-IR analysis showed the peaks at 1,077, 1,041, and $801cm^{-1}$ of the hair treated with oxidizing agent were increased compared to peak values of virgin hair, indicating that cystein in hair was decreased which is crucial to disulfide bond between keratin. On the other hand, when the damaged hair is treated with the fermented black soybean extract, cracks in the cuticle layer of the epidermis were filled, tensile strength was restored to $14.27{\pm}0.96g/cm^2$ and the ratio of oxidized cysteine in hair was decreased. These results suggest that the fermented black soybean extract is worthy of further investigation as a protective material for hair damaged by oxidizing agents.

Effects of fermented milk, $Kupffer's^{\circledR}$, intake on hepatic antioxidative systems were investigated in rats fed ethanol (3 g/kg B.W.) for 2 weeks. Serum AST and ALT were $88.7{\pm}6.5\;and\;41.2{\pm}4.1IU/L$ in control group, $114.6{\pm}7.1\;and\;64.7{\pm}3.8IU/L$ in alcohol group, and $94.0{\pm}5.5\;and\;44.7{\pm}5.3IU/L$ in fermented milk (FM) group, respectively. Fermented milk intake decreased hepatic glutathione peroxidase and superoxide dismutase activities of FM group to level of control group (p<0.05). Glutathione S-transferase activity of fermented milk group increased by 122% compared to control group. These results suggest antioxidative activities of lactic acid bacteria and ingredients in $Kupffer's^{\circledR}$ improve antioxidative system in alcohol-treated rats.

Phytochemical compounds of Ligusticum striatum Makino are used as traditional medicinal herbs in Asia. These compounds are reported to have pain relief and antioxidant activities in gynecological and brain diseases. In this study, we investigated the antioxidant effects of Ligusticum fermented ethanol extract from Lactobacillus plantarum BHN-LAB 129 isolated from Kimchi, a Korean traditional food. The total polyphenol and total flavonoid contents increased by about 116.2% and 281.0% respectively, in the fermented Ligusticum extract as compared with those in the nonfermented Ligusticum ethanol extract. Superoxide dismutase-like (SOD), DPPH radical scavenging, ABTS radical scavenging, and reducing power activities increased by around 139.9%, 199.6%, 301.0%, and 137.1%, respectively, in the fermented Ligusticum ethanol extract as compared with these parameters in the nonfermented Ligusticum ethanol extract, respectively. In conclusion, the fermented Ligusticum ethanol extract with L. plantarum BHN-LAB 129 was effective in increasing the antioxidant effects. The bioconversion process in this study points to the potential of using Ligusticum to produce phytochemical-enriched natural antioxidant agents with high added value. The findings may prove useful in the development of improved foods and cosmetic materials.

Ingredients of soy and fermented soy products have been widely utilized as food supplements for health-enhancing properties. The aim of this study was to evaluate the effects of fermented soymilk (FSM) and soymilk (SM) on free fatty acid-induced lipogenesis in the hepatocellular steatosis model. HepG2 cells were incubated with palmitic acid (PA) for 24 h to induce lipogenesis and accumulation of intracellular lipid contents. The PA-treated cells were co-incubated with FSM, SM, genistein, and estrogen, respectively. Lipid accumulation in the PA-treated HpG2 cells was significantly decreased by co-incubation with FSM. Treatment of HepG2 cells with PA combined with genistein or estrogen significantly increased the expression of SREBP-1. However, FSM co-incubation significantly attenuated SREBP-1 expression in the PA-treated HepG2 cells; in addition, expression of NRF-2 and phosphorylation of ERK were significantly increased in the PA and FSM co-incubated cells. PA-induced ROS production was significantly reduced by FSM and SM. Our results suggested that the bioactive components of FSM could protect hepatocytes against the lipid accumulation and ROS production induced by free fatty acids. These effects may be mediated by the inhibition of SREBP-1 and the activation of NRF-2 via the ERK pathway in HepG2 cells.
