Objectives : In this study, we investigated the synergistic protective effects of medicinal herbal mixture (HME) including Mori Ramulus (MR), Acanthopanacis Cortex (AC), Eucommiae Cortex (EC), and Black soybean (BS) in C2C12 cells, mouse myoblasts. Methods : Effects of HME on cell viability of C2C12 myoblasts were monitored by MTT assay. Anti-atrophic activity of HME was determined in myoblasts and myotubes under oxidative stress by H₂O₂. C2C12 myoblasts were differentiated into myotubes in a medium containing 2% horse serum for 6 days. After that, we measured that expression of MyoD and myogenine, the myogenic regulatory factors, to identify the mechanism of inhibiting muscle atophy after HME treatment. In addition, suppression of phosphorylation of Akt, FoxO3a and MARF-1, transcription factors of degradation proteins were analyzed via western blotting. Results : As a result of MTT, HME there was no show cytotoxicity up to a concentration of 1 mg/ml. The cytoprotective effects on oxidative stressed myoblast and myotube was better in HME extract than those of MR, AC, EU, and BS, respectively. HME treatment in Myotube induced by oxidative stress after H₂O₂ treatment increased Myo D, Myogenine activation, and Akt, FoxO3a phosphorylation and decreased expression of MuRF-1. As the results, HME has synergistic effects on protection against proteolysis of C2C12 myotubes through activation of the Akt signaling pathway under oxidative stress. Conclusions : These results suggest that HME may also be useful as a preventing and treating material for skeletal muscle atrophy caused by age-related diseases.

Objective : This study was conducted to investigate antidiabetic effects of chunggugjang with medicinal herbal complex (CJ) in streptozotocin (STZ)-induced animal models. Method : STZ (65 mg/kg) was injected intraperitoneally to induce diabetes. Then rats were divided into 5 groups ; NG (normal diet + 0.9% saline), COS (STZ +saline 5 mL/kg), COB (STZ + fermented soybean(100 mg/kg), CJ 100/200 (STZ+CJ(100 and 200 mg/kg), CJ 300/600 (STZ+CJ(300 and 600 mg/kg). 4 weeks later, oral glucose tolerance test (OGTT) was performed. After sacrificing rats, serum levels of blood urea nitrogen (BUN), creatinine, aspartate amino transferase (AST), alanine amino transferase (ALT), total cholesterol (TC), and triglyceride (TG) were measured and histological changes were observed. Result : Body weight change and food efficiency ratio (FER) were decreased in the CJ 300/600 group than in the COS group. But, there was no change in water intake. Serum levels of glucose, AST, ALT and BUN were lower in the CJ 300/600 group than in the COS group. Also, TG, TC, and creatinine were decreased in the CJ 300/600 group than in the COS group. According to OGTT, 120 minutes postprandial glucose levels were lower in the CJ 300/600 group than in the COS group. In addition, administration of CJ extracts restored histopathological damage. Conclusion : The results suggest that CJ can be used as a functional material for diabetes treatment as it has the effect to improve pathological symptoms in STZ-induced diabetic rats.

The Codonopsis pilosula is traditional oriental herb associated with immune-modulatory functions and has anti-inflammatory properties and antioxidative activity. The present study was conducted to investigate the effects of dietary supplementation of Codonopsis pilosula extract powder (CEP) on the immunity and productivity in sows and piglets. A total of 20 pregnant sows were randomly assigned to two dietary treatments, which was given a corn-soybean meal diet with 0% and 0.5% CEP from 40 days prepartum to weaning (25 days postpartum). The immune system of piglets was expected to build up, because the feeding of CEP might increase the colostrum contents in sows. We also predicted that the growth performance of piglets also could be increased by some compensation effects due to the increased immunity of piglets. In results, immunities of sows and piglets as well as growth performance of piglets were not affected by the supplementation of CEP. The correlation between the colostrum and the serum on the IgG contents tended to have a positive correlation, although there was no significant (coefficient, 0.435; P=0.102). This result suggests that the supplementation of CEP may increase IgG contents in sows and piglets and contribute to improve immunity of piglets. In conclusion, it is thought that the physiologically active substances of CEP did not influence to the immune synergic effects in vivo of sows. Thus, the metabolic and action mechanism of the physiologically active substances of CEP should be explored to evaluate the availability of CEP as a feed additive for the immunomodulator.

In this study, fibrinolytic activities of fermented yellow agabean (FYA) and black agabean (FBA), and the antioxidation efficiencies of 70% ethanol extract of fermented yellow agabean (FYAE) and black agabean (FBAE) were investigated by selecting Bacillus sp. sm26 strain. Fibrinolytic activities of FYA and FBA were $6.38{\pm}0.5$ and $6.83{\pm}0.5\;U/ml$, which were 1.3 and 1.4 times higher than that of FSB, respectively. With regard to total phenolic contents, FYAE and FBAE were $3.40{\pm}0.44\;mg/g$ and $2.45{\pm}0.20\;mg/g$ respectively, suggesting that their contents were about twice as high as that of fermented soybean extract (FSBE) used as a control. In comparison with FSBE, total protein and sugar contents of FYAE were $0.56{\pm}0.11$ and $2.41{\pm}0.48\;mg/g$, respectively, and those of FBAE were $0.39{\pm}0.12$ and $2.72{\pm}0.63\;mg/g$, respectively. This result suggests that FYAE was 4.7 and 1.7 times higher than FSBE, respectively. The DPPH radical scavenging activity of FBAE was 79% at 1 mg/ml, which was highest among the fermented bean extracts, and was twice as high as FSBE in regards to activity. In addition, FBAE exhibited the highest reducing power at 1 mg/ml, which was higher than FSBE by two-fold. With regard to lipid peroxidation, FBAE and FYAE were 93% and 80% at 1 mg/ml, which were 3 and 2.5 times higher than FSBE, respectively. Of note, the hydrogen peroxide scavenging activities of FBAE and FYAE were 82% and 54% at 1 mg/ml, offering activity that was 4 and 2.5 times higher than FSBE, respectively. Based on these results, the fibrinolytic activity and antioxidation efficiency of the fermented agabeans were significantly higher than other soybeans. Therefore, these studies may suggest that the functional agabeans can be a potential candidate for a natural functional food.

This study was conducted to develop functional sources of herbal cosmetics for treatment of skin aging and inflammatory disorders using volatile flavor extracts of four different herbal medicinal prescriptions including Cnidium officinale Makino (COM), Angelica gigas Nakai (AGN), Mentha arvense L. (MAL), Artemisiae argyi Folium (AAF), Paeonia lactiflora Pall (PLP), Rehmanniae Radix Preparata (RRP), Scutellaria baicalensis Georgi (SBG), Panax ginseng C.A. Meyer (PGM), Glycyrrhiza uralensis Fisch (GUF). The volatile flavor extracts of four different herbal medicinal prescriptions (HH-1: COM, AGN, PLP, RRP, HH-2: COM, AGN, PLP, RRP, SBG, PGM, GUF, HH-3: COM, AGN, MAL, AAF, HH-4: COM, AGN, MAL, AAF, SBG, PGM, GUF) were extracted using SDE and their antioxidant and anti-inflammatory effects were measured by using DPPH radical and SLO, respectively. As a result, HH-2 showed moderate DPPH radical scavenging activity (68.24 %) and the strongest SLO inhibitory activity (83.96 %) at 100 ${\mu}g$/mL. Moreover, HH-2 of four different prescriptions significantly inhibited NO production on LPS-stimulated RAW 264.7 cells in a dose-dependent manner without considerable cell cytotoxicity at range of 2.0 ~ 50 ${\mu}g$/mL. Additionally, HH-2 also effectively suppressed the production of $PGE_2$ and IL-6, which are responsible for promoting the inflammatory process. Major volatile components of HH-2 were identified as eugenol, paeonol, butyl phthalide, ${\beta}$-eudesmol and butylidene dihydrophthalide by GC-MS analysis. Thus, these results suggest that HH-2 may be useful as a potential source of anti-inflammatory agents in herbal medicinal cosmetics.

The effects of rice hull (RH) powder on the anticarcinogenic activity of submerged-liquid cultures of Agaricus blazei Murill (AB) were assessed for mouse ascites cancers induced by mouse Sarcoma S-180 (S-180) cancer cells. Optimal growth of AB mycelia in the basal liquid culture medium, containing soybean meal, was achieved by culturing at $25^{\circ}C$ for 5 days, when evaluated by $\beta$-glucan content, Brix, and mycelial weight, relative to other culture conditions. Hot-water extract (HWE) of the submergedliquid culture of AB mycelia grown at $25^{\circ}C$ for 5 days exhibited a stronger anticarcinogenic activity, relative to HWE from other culture conditions. No such effects were obtained from AB mycelial cultures by alternative temperature-controlling cultures. Both cytotoxicity for S-180 cells and anticarcinogenic potentials for mouse ascites cancer of the HWE from AB mycelia grown in the basal medium containing 1% RH powder for 5 days at $25^{\circ}C$ were significantly (p<0.05) enhanced, relative to HWE from the AB mycelia culture of the basal medium without RH powder. These results indicate that HWE of submerged-liquid culture of AB mycelia, incubated in media containing 1% RH powder at $25^{\circ}C$ for 5 days, enhanced anticarcinogenic activity against S-180 cell-induced mouse ascites cancer, and suggest that RH powder is an excellent ingredient for the improvement of the anticarcinogenic potentials of the submerged-liquid culture of mushroom mycelia.

As a way of mass process of onion, Allium cepa L., the oleoresin decompressed and concentrated is an alternative process to minimize lowering in the quality of onion during storage, to improve the original flavor and taste, and to increase variety as processing aids. This study was performed to investigate on the quality stability during storage of oleoresin. Oleoresin product was manufactured by mixing a concentration of onion juice and ethanol extract homogenously, emulsified by an additional 2% PGDR(polyglycerol condensed ricinoleate) and 1% cysteine. During 60 days storage at 5$^{\circ}C$, $25^{\circ}C$ and 4$0^{\circ}C$ the total sugar content in oleoresin product was very stable, and absorbances at 420nm as browning reaction index were 0.38, 1.53 and 3.32, respectively, addition of 1% cysteine retarded the browning reaction effectively. When oleoresin product was centrifuged(2000$\times$G, 60 minutes), the volumes of emulsion level without separation were 96.8%, 94.1% and 9.06%, respectively during 20 days, 40 days and 60 days storage at 5$^{\circ}C$, and those during 60 days storage at $25^{\circ}C$ and 4$0^{\circ}C$ were appeared to be 83.2% and 75.4%. Showing lower level as increasing storage temperature. Antioxidant indexes(AI) of soybean oil added 1% oleoresin without storage and 0.02% BHA were 1.39 and 1.72. The former showed 80.8% antioxidant activity on induction time extension effect of the latter. Antioxidant indexes of oleoresin decreased slightly as increasing storage temperature and were 1.37, 1.30 and 1.08. Total pyruvate contents were 89.9%, 79.7% and 65.2%, respectively during 60 days storage at 5$^{\circ}C$, $25^{\circ}C$ and 4$0^{\circ}C$. Rate constant, Q10 value and activation energy were 1.381~4.735 mmol/$\ell$.hr, 1.537~1.694 and 11.649 ㎉/g mole for the reduction of pyruvates in the range of storage temperatures during oleoresin storage.
