Matrix metalloproteinase-9 (MMP-9) is considered to be an important component in the progression of inflammation. Monocytes/macrophages are prominent at inflammation sites, and activation of these cells by stimulants such as lipopolysaccharide (LPS) leads to the production of significant amounts of MMP-9. Here, we show that LPS-induced MMP-9 production and activation was inhibited by the water extract from the fruit of Chaenomeles sinensis (CS), the root of Polygonum cuspidatum (PC), but increased by the extract from Boswellia carterii (BC). To investigate the mechanism by which those extracts inhibits MMP-9 activation, we examined the level of MMP-9 mRNA expression. We observed a significant change in the MMP-9 expression between LPS alone and LPS plus Chaenomeles sinensis and Polygonum cuspidatum extracts-treated cells. In addition, LPS significantly up-regulated MMP-9 promoter activity in Raw 264.7 cells, which was attenuated by the CS and PS extracts. However, water extracts from Boswellia carterii increased MMP-9 expression and MMP-9 promoter activity which were induced by LPS treatment in Raw 264.7 cells. These data suggest that water extracts from Chaenomeles sinensis and Polygonum cuspidatum can modulate anti-inflammatory immune response, which may be in part associated with the regulation of MMP-9 production and/or activation through the regulation of MMP-9 expression in mouse macrophage cells.

Schisandra chinensis (SC) and Lycium chinense (LC) were widely distributed in Asia and the fruit has been used traditionally for medicinal herbs. The processing method was solid-state fermentation using Aspergillus oryzae for 48 h after stir-frying treatment at $220^{\circ}C$ for 12 min. In this study, in vitro the anti-inflammatory effect and in vivo hangover reduction were compared to unprocessed SC and LC water extract. Anti-inflammatory effects have been evaluated in pro-inflammatory mediators which were secreted by lipopolysaccharide (LPS)-induced RAW 264.7 macrophages. Nitric oxide (NO) was determined using Griess reaction. Proinflammatory cytokines such as tumor necrosis factor $(TNF)-{\alpha}$ and interleukin $(IL)-1{\beta}$ were measured by enzyme-linked immunosorbent assays (ELISA). Alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) activities were compared to processed SC or LC and mixtures thereof (1:1). In vivo study was compared to hangover relief in alcohol-fed mice. After administering a mixture of SC and LC (300 mg/kg) water extract (1:1), mice were fed 3 g/kg of ethanol. Serum was collected at 1, 3, and 5 h intervals to analyze ethanol and acetaldehyde levels using a colorimetric assay kit. The processed SC and LC water extracts compared to raw materials significantly inhibited LPS-induced NO and inflammatory cytokine production in RAW 264.7 cells. The results of the hangover mouse model are also consistent with anti-inflammatory effects. These results suggest that processed SC and LC extracts may be functional materials for the treatment of inflammation and hangover.

In this research, the total polyphenol and flavonoid contents in the hot water extract (HE) and methanol extract (ME) of the Coriolus versicolor fruiting body and their partial bioactivities were investigated from March, 2015 to February, 2016. For the analysis of the data, the software used was SPSS 2.0. The results indicate that the total polyphenol content in the HE (129.60 mg/dl) was 85,8 mg/dl higher than that in the ME (43.80 mg/dl). The total flavonoid content in the HE (30.50 mg/dl) was 9.5 mg/dl higher than that in the ME (20.90 mg/dl). The DPPH scavenging activities of the HE and ME at a concentration of 3 mg/ml were 41.03% and 16.36% higher than those at a concentration of 1 mg/ml. The tyrosinase inhibitory activities of the HE and ME at a concentration of 3 mg/ml were 8.29% and 10.32% higher than those at a concentration of 1 mg/ml. The elastase inhibitory activities of the HE and ME at a concentration of 3 mg/ml were 3.12% and 21.53% higher than those at a concentration of 1 mg/ml. The collagenase inhibitory activities of the HE and ME at a concentration of 3 mg/ml were 5.44% and 4.07% higher than those at a concentration of 1 mg/ml. In conclusion, these two kinds of extracts are judged to be useful as skin wrinkle relaxants, due to their anti-oxidative and bioactive functions.

To prevent and treat the osteoporotic fracture, more attention should be paid in old age patients. Osteoclast which has ability to bone resorption is originated from hematopoietic cell line and plays a key role osteoporotic bone loss. Rubi Fructus has been widely used in Oriental medicine. Extracts of the leaves and fruit of Rubus species have been used in various countries as natural remedies to treat diabetes, infections, colic, and burns. However, the effect of extract of Rubi Fructus (fruit of Rubus coreanus Miq.) in osteoclast differentiation remains unknown. Thus, we evaluated the effect of Rubi Fructus on receptor activator of nuclear factor-kB ligand (RANKL)-induced osteoclast differentiation. Here we found that Rubi Fructus significantly inhibited osteoclast differentiation induced by RANKL. Rubi Fructus suppressed the activation of p38 pathway and NFkB in bone marrow macrophages (BMMs) treated with RANKL. Also, Rubi Fructus significantly inhibited the mRNA expression of c-Fos, tartrate-resistant acid phosphatase (TRAP), osteoclast-associated receptor (OSCAR), nuclear factor of activated T cells (NFAT)c1 and cathepsin K in BMMs treated with RANKL. Particularly, Rubi Fructus greatly inhibited the protein expression of c-fos and NFATc1. especially in the case of NFATc1 expression, a master transcription factor of the differentiation of osteoclasts is very important step for osteoclastogenesis. Taken together, our results demonstrated that Rubi Fructus may be useful treatment option of bone-related disease such as osteoporosis and rheumatoid arthritis.

The presoaking conditions of soybeans in various solution for decreasing microbial contamination and improving germination were investigated. Soybeans were treated with presoaking solutions (sterilized water, 0.1% grape fruit extract, 0.1% vitamin $B_1$ derivate solution AS5 and vitagen) at $25^{\circ}C,\;35^{\circ}C,\;45^{\circ}C\;and\;55^{\circ}C$ for $3\sim12$ hr and germinate at $25^{\circ}C$, 95%RH for 3 days. Total bacterial count and coliform count of soybeans were $6.0\times10^5CFU/g$ and $3.0\times10^5CFU/g$, respectively, and the most of presoaking treatments decreased the microbial contamination. The increase of presoaking time induces low germination ratio compared with unsoaked soybeans and the germination of soybeans was not detected at $55^{\circ}C$. The germination of soybeans was effected by presoaking solutions, temperature, and time. The optimal presoaking condition for decreasing microbial contamination and promoting initial germination was using grape fruit extract at $35^{\circ}C$ for 6 hr.

This study was conduced to ferment high quality wine by using Omija fruit. Dry Omija farmed and dried in the Moonkyung area was used in this study. The Omija was soaked in 10~40 folds of distilled water to extract water-soluble components and the fluid was filtered after soaking for 6 hours at $50^{\circ}C$. Strains of alcoholic yeast were isolated respectively from spoiled Omija extract. Isolated alcoholic yeasts, OM-1 and OM-2, showed a round to ellipsoidal shape and formed white or milky white colonies on a solid YM medium. Two yeasts produced 10.33~11.23% alcohol from Omija extract adjusted to $10^{\circ}Brix$ with sugar. Their abilities to ferment alcohol were higher than those of other yeast strains belonging to Saccharomyces cerevisiae such as KCTC 7296 (standard strain of Korean Biological Resources Center), Makgeolli yeast, or beer yeast. The isolates OM-1 and OM-2 showed similar abilities in alcohol fermentation. However, the wine fermented by OM-2 got a better sensory score especially with color. Growth of OM-2 was significantly accelerated by addition of a 0.1% urea and 0.02% mineral mixture. A vitamin mixture was effective for the growth only when urea was added as well.

Evaluation of biological activity and analysis of functional constituents from water and ethanol extracts of four different parts of mulberry (Morus alba L.) tree were carried out to develop functional ingredients and foods using extracts of mulberry tree. The water and ethanol extracts of four different parts of mulberry tree were prepared and their biological activities and functional constituents determined by in vitro assays and HPLC, respectively. In general, ethanol extracts showed stronger biological activities and higher functional constituents than water extracts. Ethanol extracts of mulberry fruit, root bark, and twig showed stronger antioxidant ($IC_{50}=128.4{\mu}g/mL$), ${\alpha}$-glucosidase ($IC_{50}=12.0{\mu}g/mL$), and lipoxygenase ($IC_{50}=36.3{\mu}g/mL$) and tyrosinase ($IC_{50}=410.3{\mu}g/mL$) inhibitory activities, respectively, than those of other parts. Mulberry fruit and leaf showed the highest contents of anthocyanin (cyanidin 3-glucoside: 213.20 mg/100 g) and chlorogenic acid (514.97 mg/100 g), and especially ethanol extract of mulberry leaf contained higher quercetin 3-O-(6-O-malonyl)glucoside (143.25 mg/100 g) and kaempferol 3-O-(6-O-malonyl)glucoside (30.25 mg/100 g) contents without water extract of mulberry leaf. Meanwhile, mulberry twig contained both oxyresveratrol glycoside (48.90 mg/100 g) and its aglycone (21.88 mg/100 g), whereas mulberry root bark contained mostly oxyresveratrol glycoside (724.05 mg/100 g). Additionally, mulberry root bark and leaf contained much higher ${\gamma}$-aminobutyric acid (223.90 mg/100 g) and 1-deoxynojirimycin (86.07 mg/100 g) contents, respectively, than other parts of mulberry tree. These results suggest that high quality processed foods and functional foods using mixtures of mulberry fruits, leaves, twigs, and root barks should be developed for prevention and inhibition of several pathological disorders.

Among 230 species of herbal drugs screened, thirty one show the anthelmintic activities in vitro against Clonorchis sinensis, the chinese liver fluke. The active substances have been isolated and their structures identified. Some of the active substances and their derivatives have been synthesized, followed by anthelmintic activity tests. The extracts from the active drugs cause damages in organs of the adult worm in the hepatic duct of rabbit. Some fresh water fish, which function as bad hosts for the fluke, excrete defense substances against the cercaria of the fluke. The defense substances have been isolated from Cyprinus carpio and Cyprinus carpio nudus, followed by structural identification. The results are summarized as follows: l) The bark of Machilus thunbergii as well as the seed of Schizandra chinensis contain meso-dihydro-guaiaretic acid as the anthelmintic component. Among derivatives synthesized, 4-phenyl-1-((3, 4-dihydroxyphenyl)-, 4-phenyl-1-(3-hydroxy-4-methoxy phenyl)-and 4-phenyl-1-(4-hydroxy-3-methoxy phenyl)-2, 3-dimethyl butanes show considerable activities. Administration of the bark extract mainly damages the bladder of the adult worm. 2) The active substance from the roasted fruit of Prunus mume is 2-hydroxymethylfurfural. This substance is produced during the roasting process. Administration of the fruitextract causes a damage of the bladder of the adult worm. 3) The active substance from the root of Scutellaria baicalensis is 5.2'-dihydroxy-6, 7, 8, 6'-tetramethoxyflavone. 4) Beside alantolactone, a very strong anthelmintic component is contained in the root of Inula helenium. Administration of the root extract causes irreversible damage on the worm, affecting mainly the reproductive organs. 5) The cercaricidal substances from the epidermis of C. carpio and C. carpio nudus are ethyl linoleate and linoleic acid, respertively. 6) The cercaricidal substances from various kinds of fresh water fish have different $R_f$ values, implying that the defense substances are species-specific. Unexpectedly, the fish with good host function, for example Pseudorasbora parva, excrete the defense substances, too. The defense substances are possibly organ-specific in individual species; the organs essenstial for the existence of the species excrete the defense substances, allowing other parts to be invaded by the cercaria. 7) The cercaricidal fraction of Carassius carassius is detected only in the fish which have been collected during the summer time from May to September, Its secretion is not dependent on water temperature. Thus, it seems to be possible that the secretion of the defense substance would be stimulated through a contact between the fish and cercaria.
