Sopoongsan is an oriental medicinal composition including 12 medicinal herbs. Sopoongsan is known to have anti-inflammatory, antimicrobial, anti-allergic, and anticancer effects on human skin. The results of stability test showed that the creams containing Sopoongsan extracts were very stable at both accelerated temperature conditions and sun-light. And pH and viscosity of each cream did not change greatly for 56 days. From the particle size and rheological measurements, it can be known that when the amount of the Sopoongsan extracts increases, the mean value of particle size decreases, and the value of the complex modulus and loss angle increases, which means the Sopoongsan extracts help stabilize the emulsion. From the result of human patch test to assess the safety of cream containing Sopoongsan extracts, there was no stimulus of negative reaction on skin. In result of the user tests, it can be known that the higher concentration of the Sopoongsan was preferred by customers.

The ascomycete fungus Cordyceps militaris infects lepidopteran insect pupae, forming characteristic fruiting bodies called "Dong Chung Ha Cho" in Korean. They have been used as medicines owing to their anti-allergic, anti-inflammatory, and immune-enhancing effects. This fungus can be grown on the geminated soybeans Rhynchosia nulubilis, which also contains several novel isoflavones. We performed a comparative transcriptome analysis to determine core gene sets or pathways contributing to biologically active products such as isoflavone. Initially, we sequenced 2-week-old fungal cultures on different soybean agar media, where different amounts of water agar were implemented to show different surface topology. We selected 830 upregulated and 188 downregulated genes by comparing linear models of the samples (two-fold change threshold). Gene ontology analysis identified that the "IMP biosynthesis" term was significantly found in the upregulated gene sets. The pathway is involved in the synthesis of cordycepin, the reference chemical for C. militaris. This finding in the transcriptome data is consistent with the previous observation: increased cordycepin concentrations in the C. militaris cultured on germinated soybean.

간장은 한국의 전통 발효식품으로써 최근 항암 효과, 항균작용, 항산화능, 항혈전 효과 등의 효능이 보고되고 있다. 한국의 간장은 콩과 밀을 주요 원료로 사용한다. 콩의 세포벽으로부터 유래되는 다당류는 효소적 가수분해에 저항성이 있으므로, 발효가 끝난 후에도 간장에 잔존하게 되며 이것을 간장 유래 다당류(Kanjang polysaccharides, KPS)라 부른다. 본 연구에서는 산분해법과 양조법으로 제조된 시판 간장인 A~T의 20종의 투석물로부터 다당류를 제조하고, 비만세포에서 염증성 cytokine의 방출과 mRNA의 발현에 대한 KPS의 효과를 실험함으로써 항염증 효과를 조사하였다. RBL-2H3 세포에서 KPS의 처리는 histamine과 ${\beta}$-hexosaminidase의 방출을 현저히 억제시켰다. 자극된 HMC-1 세포에서 KPS의 처리는 염증성 cytokine인 IL-6, IL-8, TNF-${\alpha}$의 방출 및 mRNA의 발현을 감소시켰다. 특히, 양조간장으로부터 유래된 KPS는 산분해 간장보다 비만세포에서 우수한 항염증 효과를 나타내었다. 따라서, KPS는 알레르기성 염증반응을 억제시키는데 효과적일 것이라 사료된다.

This study investegated the effect of Liriope platyphylla (LP) on allergic reactions and its mechanism of action. We investigated the effect of LP on Evans Blue (EB) extravasation induced by anti-dinitrophenyl (DNP)-IgE in rats. We tested whether the ethanol extract of LP reduced ear skin thickness and historical changes induced by topical application of 2,4-dinitrofluorobenzene (DNFB) to ears of mice. We evaluated compound 48/80-induced release of histamine in rats peritoneal mast cell (RPMCs). We also investigated the regulatory effect of LP on the level of inflammatory mediators in PMACI-induced human mast cell (HMC-1); cytokine IL-6, IL-8, TNF-${\alpha}$ in HMC-1, MAPKs (ERK, JNK and p38) in HMC-1. The ethanol extract of LP (81.3 mg/100 g body weight) significantly inhibited the PCA reaction compared with the control (P < 0.05). However, LP did not prevent topical applications of DNFB-induced ear skin thickening and histological changes. In RPMCs, histamine release induced by compound 48/80 was significantly attenuated by LP at $100{\mu}g/ml$ (P < 0.05). LP extract ($100{\mu}g/ml$) significantly reduced the PMACI-induced IL-6, IL-8, and TNF-${\alpha}$ secretion via inhibition of ERK phosphorylation in HMC-1. In conclusion, the ethanol extract of LP inhibited mast cell-derived, immediate-type allergic reactions, and the result suggest the potential of LP for preventing allergic inflammatory disorders.

Bamboo salt has been used for the purpose of prevention and treatment of various diseases in Korea. Present study was carried out to ascertain the effects of purple bamboo salt upon anti-allergic effect, anti-inflammatory activity and immune-enhance effect as well. Purple bamboo salt significantly inhibited the ear swelling response and histamine release induced by compound 48/80 in mice and rat peritoneal mast cells. Purple bamboo salt (0.01 ∼ lg/kg) also dose-dependently inhibited the passive cutaneous anaphylaxis by oral administration. Purple bamboo salt (1 mg/mL) in hibited phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-1${\beta}$ and IL-6 secretion, by 67.04${\pm}$0.08%, 68.01${\pm}$1.85%, 69.48${\pm}$0.54%, respectively. In addition, purple bamboo salt inhibited the expression of TNF-${\alpha}$ mRNA in HMC-1 cells. Finally, we investigated the effect of purple bamboo salt in the forced swimming test (FST) and the change of purple bamboo salt-mediated cytokine production from MOLT-4 cells. At the 7th, immobility time was significantly decreased in the purple bamboo salt-administration group (35.4 ${\pm}$5.9 s for 1 g/kg) in comparison with the control group (93.2 ${\pm}$ 15.45). After FST, the content of glucose in the blood serum was increased and the levels of blood urea nitrogen, lactic dehydrogenase was decreased in purple bamboo salt-administration group. However, it had no effect on the elevation of CK and TP level. Purple bamboo salt (1 mg/mL) significantly increased the interferon (IFN)-${\gamma}$ and IL-2 level compared with media control (about 3.7-fold for IFN-${\gamma}$, about 3.5-fold for IL-2, p〈0.05) but did not affect the IL-4.

Flavonoids show diverse bioactivities, such as anti-oxidant, anti-cancer, anti-allergic, anti-inflammatory, and anti-viral. Quercetin is one of the flavonoids present in a wide range of plants, especially onions and consumed all over the world. Recently, it is known that quercetin induces mitochondrial biogenesis in vivo and in vitro. However, detail mechanism of these actions remains unknown. We investigated quercetin's effects on mitochondrial biogenesis in HepG2 cells, and determined the mechanisms involved. We found that quercetin treatment induced the expression of mitochondrial biogenesis activators, $PGC-1{\alpha}$, NRF-1, TFAM, and mitochondrial proteins, cytochorome c and complex IV (COXIV). Moreover, amount of mitochondrial DNA was also increased by quercetin. Quercetin has been known to induce heme oxygenase (HO)-1 in several types of cells. Here, we found quercetin induces HO-1, and inhibition of HO-1 or CO, which is product of HO-1, decreased quercetin-induced mitochondrial biogenesis such as induction of $PGC-1{\alpha}$, NRF-1, TFAM, cytochorome c, COXIV, and mitochondrial DNA. These findings imply that quercetin can increase mitochondrial biogenesis via HO-1/CO system. High glucose results in dysfunction of mitochondria biogenesis. In the present study, 25 mM glucose decreased mitochondrial biogenesis and this damage was restored by quercetin. Conversely, inhibition of HO-1 or CO inhibited quercetin-induced mitochondrial biogenesis rescue. These results suggest that quercetin enhances mitochondrial biogenesis via HO-1/CO system and hence, can rescue mitochondria from damage by high glucose.
