To develop new therapeutic materials to prevent hair loss and enhance hair growth, we developed a medicinal herbal complex extract (MHCE) using 23 herbs traditionally used in oriental medicine. Medicinal Herbal complex extract was consist of Angelica gigas Nakai, Psoralea corylifolia Linne, Biota orientalis Endlicher, and Eclipta prostrata Linne, Rehmannia glutinosa Liboschitz var. purpurea Makino, Ligustrum lucidum Aiton, Polygonum multiflorum Thunberg, and Sesamum indicum Linne, Sophora angustifolia Sieboldet Zuccarini, Angelica dahurica Benthamet Hooker, and Leonurus sibiricus Linne, Salvia miltiorrhiza Bunge, Prunus persica Batsch, Commiphora molmol Engler, Chrysanthemum indicum Linne, Boswellia carterii Birdwood, Panax ginseng C. A. Meyer, Cnidium officinale Makino, Albizia julibrissin Durazzini, and Corydalis ternata Nakai that have traditionally been used for treating hair loss, preventing gray hair, anti-inflammation, and blood circulation in oriental medicine. In addition, we examined the hair growth effect of MHCE in vitro and in vivo. In vitro, we evaluated the effects of MHCE on cultured HFDPC, HaCaT cells, and murine embryonal fibroblasts (NIH3T3 cells). Also, we evaluated the ability of MHCE to prevent gray hair on murine melanoma cells (B16F1 cells). The hair growth-promoting effect of MHCE in vitro was also observed in vivo using C57BL/6 mice. Our results showed that MHCE significantly increased the proliferation of HFDPC (175 % proliferation at $50{\mu}g/mL$), HaCaT cells (133 % proliferation at $20{\mu}g/mL$), and NIH3T3 cells (120 % proliferation at $50{\mu}g/mL$). MHCE also showed consistent melanogenesis in B16F1 cells (154 % melanin synthesis at $50{\mu}g/mL$). Moreover, MHCE showed potential for hair growth stimulation in C57BL/6 mice experiments (98 % hair growth area on 4 weeks). These results indicate that MHCE may be a good candidate for promotion of hair growth.

The antioxidant and anticancer effects of the edible mushrooms Lentinus edodes (LE, Pyogo mushroom) and Agaricus blazei (AB, Agaricus mushroom), and the medicinal mushrooms Cordyceps militaris (CM, Dong chunghacho), Ganoderma lucidum (GL, Youngji mushroom), Inonotus obliquus (IO, Chaga mushroom), and Phellinus linteus (PL, Sangwhang mushroom) were studied in vitro. The bioactive components were extracted by methanol. The antioxidant effects were evaluated using the DPPH and hydroxyl radical scavenging assays. The antioxidant activities of medicinal mushrooms (35~90%) were higher than edible mushrooms (4~23%). The in vitro anticancer effects of the mushrooms were evaluated using the MTT assay in AGS gastric adenocarcinoma cells, HCT-116 colon carcinoma cells, and HepG2 hepatoma cells. The medicinal mushrooms CM, GL, IO, and PL showed 28~91% inhibition, while the edible mushrooms LE and AB exhibited 5~40% inhibition. The medicinal mushrooms, compared to edible mushrooms, effectively down-regulated the gene expression of the anti-apoptosis related gene Bcl-2 and inflammation-related genes iNOS and COX-2, and up-regulated the pro-apoptosis gene Bax (p<0.05). Total polyphenol and flavonoids contents of the medicinal mushrooms were 9.1~35.7 mg/g, while the edible mushrooms showed 0~13.3 mg/g. This study showed that antioxidant activities and anticancer activities in vitro increased in the order LE, AB, GL, CM, IO and PL. LE and AB showed the lowest effects among the samples, GL and CM had medium effects, and IO and PL exhibited the highest effects in the antioxidant and anticancer effect for three different human cancer cells. Taken together, PL resulted in the highest and LE the lowest effects in this study.

We have previously screened 150 medicinal plants on the inhibition of elastase and found a significant inhibitory effects of the extracts of Areca catechu L. on the aging and inflammation against the skin tissues. To isolate and identify the compounds having biological activity, we was further purified by each of the solvent fractions, silica gel column chromatography, preparative TLC and reversed-Phase HPLC. Peak in HPLC, which coincided with the inhibitory activity against elastase, was identified as Phenolic substance using various colorimetric methods, UV, and IR. $IC_{50}$/ values of phenolic substance purified from Areca catechu were 26.9 $\mu\textrm{g}$/$m\ell$ for porcine pancreatic elastase (PPE) and 60.8 $\mu\textrm{g}$/$m\ell$ for human neutrophil elastase (HNE). This Phenolic substance showed more potent activity than those of reference compounds, oleanolic acid (76.5 $\mu\textrm{g}$/$m\ell$ for PPE, 219.2 $\mu\textrm{g}$/$m\ell$ for HNE) and ursolic acid (31.0 $\mu\textrm{g}$/$m\ell$ for PPE, 118.6 $\mu\textrm{g}$/$m\ell$ for HNE). According to the Lineweaver-Burk Plots, the inhibition against both PPE and HNE by this phenolic substance was competitive with substrate. Phenolic substance from Areca catechu exhibited high free radical scavenging effect ($SC_{50}$/ : 6 $\mu\textrm{g}$/$m\ell$) and inhibited effectively hyaluronidase activity ($IC_{50}$/: 210 $\mu\textrm{g}$/$m\ell$). These results suggest that the Phenolic substance Purified from Areca catechu showed anti-aging effect by protecting connective tissue proteins.

Today, as the specification of pigs increases, it is important to develop eco-friendly livestock feeds that do not add antibiotics to highly utilizable materials as feed resources, and to produce functional eco-friendly pork and processed products. The purpose of this study was to establish Rubus occidentalis (RO) byproducts containing various amounts of physiologically active substances such as anticancer, anti - inflammation and antioxidant as a raw material for pig feed. The multifaceted efficacy of the RO fermented fodder (ROFF) was confirmed by the nutrient transport factors and antioxidant activity of Berkshire pigs. ROFF was added 0.3% to the general diet and the efficacy was confirmed by feeding diets to Berkshire pigs according to each weight for 43~73 days. As a result, the total cholesterol (TC), LDL-cholesterol (LDL-C) and HDL-cholesterol (HDL-C) levels were decreased or were increased in the castrated male and female Berkshire pigs but not significantly. It was confirmed that the tendency was improved in nutrition physiology. The biochemical levels of female finishing pigs were not significant but increased. In the case of finishing pigs with possibility of pregnancy, it is expected that the nutrition supply for piglet production and will help in the production of the healthy piglet. Transferrin (TFE) levels tended to increase in female growing pig and 110-150 kg finishing pigs. Thus ROFF could minimize the negative effects of iron contents deficiency in female Berkshire pigs. Glutathione peroxidase 1 (GPx1) activity was increased in castrated male and female 110-150 kg finishing pigs. Therefore, ROFF tends to improve the antioxidant capacity. The results of this study suggest that ROFF is one of the most favorable dietary sources when considering the contents of RO in feed. In particular, ROFF could have a positive effect on nutrient transport and iron content of female rather than castrated male Berkshire pigs.

Background : Uteroglobin is a protein produced by the normal bronchial epithelium and its expression level is lower in non-small cell lung cancer tissues and cell lines. It mainly functions as an anti-inflammatory, and when it is overexpressed in cancer cells, the neoplastic phenotype is antagonized. cPLA2 and COX-2, which are also associated with inflammation, were reported to be related to cancer. The relationship between cPLA2, COX-2 and uteroglobin is unclear. The relationship between uteroglobin and ERK, which is related to cell growth, is also not unclear. This study investigated the changes in the cPLA2 and COX-2 expression levels and the ERK activities after the overexpression of uteroglobin in non-small cell lung cancer cell lines. Methods : The A549 and NCI-H460 cell lines were infected by adenovirus-null and adenovirusuteroglobin. The cChange in the cPLA2, COX-2 expression level and ERK activity after uteroglobin overexpression was measured by Western blot. The change in MMP activity was measured by zymography. Results : Western blot revealed decreased expression levels of cPLA2, and COX-2, and increased pERK levels in nonsmall cell lung cancer cells after uteroglobin overexpression. Zymography revealed no changes in the MMP-2 activity and lower MMP-9 activity. U0126, which is a specific inhibitor of ERK-activating kinase MEK-1/-2, prevented the decrease in the MMP-9 activity Conclusions : A decrease in cPLA2 expression, COX-2 expression, MMP-9 activity and a increase in ERK activity may be related to the anticancer effects of uteroglobin in nonsmall cell lung cancer cells.

Traditional medicinal plants are widely used to treat many diseases, such as inflammation, infections, and even cancer. Ulmus macrocarpa Hance, a Chinese elm species, is distributed in Korea, China, and Japan. The stem bark is widely employed in Korean traditional medicine to treat dermatitis, mastitis, and edema. The aim of this study was to investigate whether water extract of U. macrocarpa Hance bark (Ulmus cortex) has a immune-modulating function in a mouse model. Three different concentrations (30 mg/kg, 100 mg/kg, and 300 mg/kg) of Ulmus cortex water extract (UCWE) were orally administered to mice for 14 days, and their immune responses were analyzed. Cytokines, such as interleukin (IL)-2, IL-12, and IFN-${\gamma}$, increased in the blood of UCWE-fed groups when compared with a control group. In contrast, the IL-4 level did not change in any of the UCWE-fed groups Cell-mediated cytotoxicity was also assayed using lymphokine-activated killer cells (LAK). LAK showed greater cytotoxicity in the UCWE-fed groups than LAK in the control group. Internal organ indices, such as liver, kidney, spleen, and thymus, were similar in all the groups, including the control group, indicating that UCWE may have been nontoxic in the experimental animals. These data suggest that UCWE has an immune-modulating function in a mouse model.

Toll-like receptors (TLRs) play an important role in induction of innate immune responses. The activation of TLRs triggers inflammatory responses that are essential for host defense against invading pathogens. Phenethyl isothiocyanate (PEITC) extracted from cruciferous vegetables has an effect on anti-inflammatory therapy. Dysregulated activation of nuclear factor-${\kappa}$B (NF-${\kappa}$B), inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2) has been shown to play important roles in the development of certain inflammatory disease. To evaluate the therapeutic potential of PEITC, NF-${\kappa}$B activation and COX-2 and iNOS expression induced by lipopolysaccharide (LPS, TLR4 agonist), polyinosinic-polycytidylic acid (Poly[I:C], TLR3 agonist), 2 kDa macrophageactivating lipopeptide (MALP-2, TLR2 and TLR6 agonist) or oligodeoxynucleotide 1668 (ODN1668, TLR9 agonist) were examined. PEITC inhibits the activation of NF-${\kappa}$B induced by LPS or Poly[I:C] but not by MALP-2 or ODN1668. PEITC also suppressed the iNOS expression induced by LPS or Poly[I:C]. However, PEITC did not suppress COX-2 expression induced by LPS, Poly[I:C], MALP-2, or ODN1668. These results suggest that PEITC has the specific mechanism for antiinflammatory responses.

Background : Cough may be a consequence of bronchial hyperresponsiveness or inflammation. Empirical treatment is important in this context because it difficult to verify the obvious cause of cough using laboratory tests, Corticosteroid has a nonspecific anti-inflammatory effect, and can be used for cough management. However, its response rate has not yet been fully elucidated. This study investigated the short- term effects of inhaled corticosteroid on chronic cough Methods : Patients with chronic cough with a normal chest radiograph and a pulmonary function test were enrolled. Cases with a prior respiratory infection within 8 weeks, a history of bronchial asthma, objective wheezing on examination, subjective symptoms of gastroesophageal reflux or taking an ACE inhibitor were excluded. On the first visit, a methacholine bronchial provocation test, spontaneous sputum eosinophil count performed twice and a paranasal sinus radiograph were checked, and the patients were treated with budesonide turbuhaler $800{\mu}g/day$ for ten days. The primary outcome measure was a decrease in the cough score after treatment. Results : Sixty nine chronic coughers were finally analyzed. The final diagnoses by the routine tests were as follows: bronchial asthma 13.0%, eosinophilic bronchitis 18.8%, paranasal sinusitis 23.2% and non-diagnostic cases 53.6%. The following responses to the inhaled corticosteroid were observed: definite responders, 76.8%, possible responders, 2.9% and non-responders, 20.3%. The response rate was not affected by the final diagnosis even in the non-diagnostic cases. There were minimal adverse drug related effects during the empirical treatment. Conclusion : Routine objective tests such as methacholine provocation, sputum eosinophil count and simple radiographs were notare not suitable for diagnosing chronic cough Therefore, empirical treatment is important. Short term inhaled corticosteroid is effective and can guide a further treatment plan for chronic cough.

Background : Eotaxin a CC chemokine specific for eosinophils, is implicated in the pathogenesis of asthma by recruiting eosinophils into the airways. Theophylline has been used for the treatment of asthma and recently was proposed to have an anti-inflammatory action. The aim of this study is to examine whether theophylline may inhibit the eosinophilic airway inflammation by reducing the expression of eotaxin. Methods : The expression of eotaxin mRNA was assessed by Northern analysis in A549 cells 4 h after stimulation with TNF-$\alpha$ or IL-1$\beta$. And then, theophylline was added to A549 cells stimulated with 0.1 ng/mL IL-1$\beta$. Results : Eotaxin mRNA expression rates induced by 0.1, 1, 10 ng/mL TNF-$\alpha$ as compared with $\beta$-actin, were 7%, 22%. 28%, respectively. Eotaxin mRNA expression rates induced by 0.01, 0.1, 1, 10 ng/mL IL-1$\beta$, as compared with $\beta$-actin, were 10%, 42%, 63%, 72%, respectively. Eotaxin mRNA expression rates after the addition of 0, 0.001, 0.01, 0.1 ${\mu}M$ dexamethasone induced by 10 ng/mL TNF-$\alpha$ as compared with $\beta$-actin, were 27%, 18%, 8%, respectively. Eotaxin mRNA expression rate after the addition of 0, 0.001, 0.01, 0.1 ${\mu}M$ dexamethasone induced by 0.1 ng/mL IL-1$\beta$ as compared with $\beta$-actin, were 43%, 47%, 12%, 8%, respectively. Eotaxin mRNA expression rates after the addition of 0, 0.001, 0.01, 0.1, 1, 10 mM theophylline induced by 0.1 ng/mL IL-1$\beta$, as compared with $\beta$-actin, were 48%, 40%, 33%, 22%, 16%, 14%, respectively. Conclusion : These results suggest that theophylline may reduce eosinophil infiltration of the airway at least in part by reducing the expression of eotaxin under the conditions of these experiments.

Asthma is a chronic inflammatory disease characterized by recurring symptoms, airflow obstruction, and bronchial hyper-responsiveness. The onset of asthma for most patients begins early in life, and current asthma treatment with anti-inflammatory agents can have adverse effects, eventually leading to impaired quality of life. In the pathogenesis of asthma, macrophages and basophils play a vital role during progression. Macrophages not only induce inflammation by secreting inflammatory cytokines but also promote DNA damage and mucus production through nitric oxide (NO) production. Basophils enhance eosinophil recruitment and aggravate asthma through the FcεRIα receptor with high affinity for histamine and IgE. Therefore, in this study, we investigated whether the activation of macrophages and basophils is suppressed by the individual extracts of 28 natural products. RAW 264.7 cells (mouse macrophages) were treated with the natural products in LPS, and 4 natural product extracts resulted in decreased NO production. In β-hexosaminidase assay using RBL-2H3 cells (rat basophils), 19 natural product extracts decreased β-hexosaminidase production. In NO production and β-hexosaminidase assay using macrophages and basophils, 3 natural product extracts (Plantago asiatica, Centella asiatica, and Perilla frutescens var. japonica) significantly inhibited NO production and β-hexosaminidase release. Overall, we examined the inhibitory effects of 28 natural product extracts on macrophage and basophil activity, and the findings demonstrated the potential of natural product extracts for treating asthma and macrophage- and basophil-related diseases.
