To investigate the anti-photoaging effect of fermented Red Ginseng(RG) in SKH-1 mice. We examined the effects of extracts of non-fermented RG(NRG group), fermented RG(FRG group) and fortified fermented RG(FFRG group) on skin wrinkles formation, histological changes related to the number of epidermal cell layers, epidermal thickness, neutrophil infiltration into dermis, degradation of collagen fibers, and the number of mast cells, and immunohistochemical changes related to cytokines and enzymes in photoaging skin caused by UVB irradiation of SKH-1 mice. The oral administration(300 mg/Kg B.W./day) and topical application($100{\mu}{\ell}/mouse/day$) of extracts of NRG, FRG and FFRG inhibited increases in epidermal thickness and wrinkle formation compared to control group in dorsal skin induced by UVB irradiation. We observed more increased stainability of acid fuschin and aniline blue in dermis of FFRG group than those of other groups. Furthermore, NRG, FRG and FFRG prevented the disruption of collagen fibers within papillary layer of dermis, and decreased number of mast cells in the dorsal skins induced by UVB irradiation. We observed fine wrinkle formation in FFRG group. Treatment with NRG, FRG and FFRG decreased immunohistochemical density of myeloperoxidase related to inflammation in the photoaging skin. We observed more decreased immunohistochemical density of myeloperoxidase in FFRG group than those of other groups. Immunohistochemical density of PCNA and Ki-67 in FFRG group was more decreased than those of other groups. Our study suggests that fermented red ginseng extracts participates in inhibitory effects in the morphological processes related to photoaging skin on UVB irradiated SKH-1 mice.

As fermented milk has been regarded as health food, the consumption of fermented milk has been increasing significantly these days. But there is not sufficient information on the effect of fermented milk on oral health. We have investigated the effect of long-term intake of t\fermented milk on saliva in preschool children, Sixty-four healthy, unmedicated preschool children were included in this study and were divided into control, fermented milk, and milk groups. The experimental period was 210days. We investigated the number of slaivary S. mutans, lactobacilli, and Candida, salivary pH, viscosity, and the concentration of salivary IgA at the beginning of the experiment. We examined these parameters at 10, 60, 110, 160, and 210 days after. The obtained results were as follows : 1. There were increases in the numbers of slaivary S. mutans in all groups through the experimental period. But, there was no consistent and significant difference among groups. 2. There was no significant change in the number of salivary lactobacilli in the fermented milk group throughout the experimental period. 3. The numbers of salivary Candida in the fermented milk and milk groups showed less fluctuation than that of the control group through the experimental period. 4. There was no decrease of salivary pH in all groups through the experimental period. 5. There were increases in the values of salivary viscosity in all groups. But, there was no consistent and significant difference among groups. 6. There were no consistent and significant difference in the concentration of salivary IgA in all groups through the experimental period. 7. There were increases of dmfs rate in all groups. But, there were no significant difference within each groups.

Water Fermented and Ethanol Fermented Extracts from Rhei Radix et Rhizoma exhibit potent anti-inflammatory activity with an unknown mechanism. To elucidate the molecular mechanisms of W-FR and E-FR on pharmacological and biochemical actions in inflammation, we examined the effect of W-FR and E-FR on pro-inflammatory mediators in lipopolysaccharide (LPS)-stimulated macrophages. The investigation focused on whether FR inhibited nitric oxide (NO), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin-6 (IL-6) and the expressions of iNOS, COX-2 in LPS-stimulated RAW 264.7 cells. We found that FR inhibited LPS-induced NO, TNF-${\alpha}$ and IL-6 productions as well as the expressions of iNOS and COX-2. These results suggest that W-FR and E-FR have inhibitory effects on LPS-induced TNF-${\alpha}$, NO, and IL-6 production, as well as the expressions of iNOS and COX-2 in the murine macrophage.

The study was performed by examining the effects of fermented liquid of Crataegi Fructus on the lipid profile improvement in rats fed high fat diets. Sprague-Dawley rats of weighting $180.0{\pm}30g$ were randomly divided into five groups : basal diet (Normal control group, NCG), only high fat diet (High fat control group, HFC), high fat diet and supplemented with 1.69 mg/100 g body weight, 3.38 mg/100 g body weight, 6.76 mg/100 g body weight by fermented liquid of Crataegi Fructus - HFL, HFM, HFH group). These experimental diets were fed for 6 weeks. The fermented liquid of Crataegi Fructus fed groups had more significantly decreased in the levels of serum total cholesterol, triglyceride, LDL-cholesterol and atherogenic index than the high fat control group, while the HDL-cholesterol was higher when compared to the normal control group. Total lipid, total cholesterol, triglyceride, LDL-cholesterol contents in liver were decreased in high fat experimental groups. But the degree of increment was reduced by administration of fermented liquid of Crataegi Fructus. while the fermented liquid of Crataegi Fructus fed group had ore significantly increased in the level of HDL-cholesterol than the high fat control group. The singularity of the unsaturated fatty acid contents attracted our attention. Especially, the polyunsaturated fatty acid compositions were 36.36%, 34.70%, 20.31%in serum, liver and fecal of fermented liquid of Crataegi Fructus fed groups, respectively. These results imply that the fermented liquid of Crataegi Fructus can be used as possible food resources and medicinal food materials.

Background: Constipation is one of the most common functional gastrointestinal disorder. The present study examined the ability of water extract of fermented (FRC) and non-fermented (NFRC) roasted Cassia tora to improve intestinal function and reduce constipation in a rat constipation model. Methods and Results: Different concentration of FRC and NFRC were orally administered loperamide (5 mg/kg; LOP) reduced the number, weight, and water content of feces, as well as intestinal transit motility. However, 24 h-(24 hour fermented roasted-Cassia tora) 300 mg/kg FRC administration increased the number, weight, and water concent of feces, compared to that seen in the LOP group, and also improve intestinal transit mitility and, the thickness of distal colon and mucous fluid. Conclusions: The results of the present study indicated that LOP-induced constipation was improved by treatment with FRC. Therefore FRC could be used to develop functional foods or natural medicine for constipation. However, further study is needed to clarify how fermentation improves the medicinal properties of roasted C. tora.

To elucidate the protective effects of Lactobacillus acidophilus-fermented milk against cadmium toxicity, the effects of administration of L acidophilus-fermented milk on hematological values and histopathological changes in cadmium-treated rats were investigated. The experimental rats were divided into 2 groups that were consisted of the one group administered with cadmium alone, and the other group administered with cadmium mixed with the fermented milk. Each group was orally administered with different doses of cadmium such as $1.7{\mu}g/g$ bw/day, $3.4{\mu}g/g$ bw/day, $6.8{\mu}g/g$ bw/day, and $13.6{\mu}g/g$ bw/day, respectively, for 1 to 8 weeks. Hematological values and enzyme activities, histopathological changes of kidney tissues were examined for the experimental groups. The values of RBC, WBC, and Hb in the groups administered with cadmium mixed with the fermented milk showed no significant differences to those of the groups administered with cadmium alone, but Hct showed significant reducing values. The activities of glutamic oxaloacetic transaminase(GOT) and glutamic pyruvic transaminase (GPT) in serum were significantly reduced than those of the groups administered with cadmium alone, at the low dose of cadmium treated groups. But alkaline phophatase(ALP) and lactate dehydorgenase(LDH) were significantly reduced at the high dose of cadmium treated groups. In histopathological study, a severe acute tubular necrosis of the convoluted tubules and distalation of tubules were showed in the groups administered with cadmium alone, but the kidney tissues of the groups administered with cadmium mixed with the fermented milk were similar to those of the normal group. In conclusion, the above results would suggest that L acidophilus-fermented milk has reducing effects on cadmium toxicity, at the low dose of cadmium administration.

When extracts of KMG (Korean mountain ginseng) leaf tea and fermented KMG leaf tea were compared, the fermented KMG leaf tea extract showedhigher activity at each stage of density. Among the material groups, the KMG extract hadthe least profound SOD-like activity, and similar SOD-like activities were noted in the fermented KMG, KMG leaf tea, and fermented KMG leaf tea extracts. With regard to nitrite scavenging ability at a pH of 1.2, the KMG, fermented KMG, and KMG leaf tea groups exhibited similar results, and at pH 3.0, the KMG and KMG leaf tea extract groups exhibited more profound nitrite scavenging ability compared to the fermented groups. In the case of HeLa cell treatments, the KMG and fermented KMG leaf tea extracts exhibited cancer cell propagation restraint rates in excess of 30%, at a density of 1 mg/mL. And MCF-7 cells treated with fermented KMG and KMG leaf tea showedsimilar propagation restraint rates at more than 27% of cancer cells, at a density of 1 mg/mL. Among the materials, the KMG extract hadthe lowest cancer cell propagation restraint rate at 21%, and the fermented KMG leaf tea extract had the highest rate at more than 70%.

Chemopreventive activities of polysaccharides from soybeans fermented with either Phellinus igniarius or Agrocybe cylindracea were investigated by measuring the induction of quinone reductase (QR), glutathione S-transferase (GST) activities, and glutathione (GSH) levels in the cell culture along with inhibition of polyamine biosynthesis. The polysaccharides from soybeans fermented with P. igniarius strongly (p<0.005) induced QR activity at all concentrations tested. The extract not only induced GST activity in a dose-dependent manner in the concentration range of 0.1-1.0 mg, but significantly induced GSH revels in cultured Hepa 1c1c7 cells with a maximal 1.4-fold increase at 0.1 mg. The polysaccharides from soybeans fermented with A. cylindracea were effective in inhibiting polyamine metabolism. These results suggest that polysaccharides from soybeans fermented with P. igniarius or A. cylindracea have cancer chemopreventive activities in in vitro models and, therefore, could be considered as potential agents for cancer chemoprevention.

Background: Ginseng contains many small metabolites such as amino acids, fatty acids, carbohydrates, and ginsenosides. However, little is known about the relationships between microorganisms and metabolites during the entire ginseng fermentation process. We investigated metabolic changes during ginseng fermentation according to the inoculation of food-compatible microorganisms. Methods: Gas chromatography mass spectrometry (GC-MS) datasets coupled with the multivariate statistical method for the purpose of latent-information extraction and sample classification were used for the evaluation of ginseng fermentation. Four different starter cultures (Saccharomyces bayanus, Bacillus subtilis, Lactobacillus plantarum, and Leuconostoc mesenteroide) were used for the ginseng extract fermentation. Results: The principal component analysis score plot and heat map showed a clear separation between ginseng extracts fermented with S. bayanus and other strains. The highest levels of fructose, maltose, and galactose in the ginseng extracts were found in ginseng extracts fermented with B. subtilis. The levels of succinic acid and malic acid in the ginseng extract fermented with S. bayanus as well as the levels of lactic acid, malonic acid, and hydroxypruvic acid in the ginseng extract fermented with lactic acid bacteria (L. plantarum and L. mesenteroide) were the highest. In the results of taste features analysis using an electronic tongue, the ginseng extracts fermented with lactic acid bacteria were significantly distinguished from other groups by a high index of sour taste probably due to high lactic acid contents. Conclusion: These results suggest that a metabolomics approach based on GC-MS can be a useful tool to understand ginseng fermentation and evaluate the fermentative characteristics of starter cultures.
