Recently, increased attention has been directed toward medicinal extracts and their active ingredients as potential new drug candidates for androgenic alopecia. Resina Pini (RP), a resinous exudation obtained from Pinus sp. (Pinaceae), has been used as a traditional medicine for the treatment of infection, pain related to dental caries, and periodontal disease. Previously, we suggested that RP and its main constituent, abietic acid (abieta-7,13-dien-18-oic acid; AA), may play important roles against androgenic alopecia as $5{\alpha}$-reductase inhibitors. However, to date, there is no evidence that AA has hair growth-promoting effects in vivo. In this study, we found that 10 ~ 300 mg/kg RP and 3 ~ 30 mg/kg AA significantly promoted hair growth in a C3H/HeN mouse model of alopecia. To our knowledge, this is the first report of the hair growth-promoting effects of RP and AA in vivo. From these results, RP and its main constituent AA can promote hair growth in mouse by inhibiting $5{\alpha}$-reductase activity and may be effective alternative therapies for androgenic alopecia.

Anthriscus sylvestris (L.) Hoffm. is a perennial herb found widely distributed in various regions of Korea, Europe, and New Zealand. The root of A. sylvestris have been extensively used in the treatment for antitussive, antipyretic, cough remedy in Oriental medicine, but the physiologically active function of the leaf of A. sylvestris is as yet unknown. In this study, we investigated the anti-cancer activity and the mechanism of cell death of water extracts of leaf of Anthriscus sylvestris (WELAS), on human FaDu hypopharyngeal squamous carcinoma cells. Our data showed that WELAS treatment inhibited cell viability in a concentration- and time-dependent manner. In addition, the treatment of WELAS markedly induced apoptosis in FaDu cells, as determined by the viability assay, DAPI stain and FACS analysis. WELAS also increased the proteolytic cleavage of procaspase-3, -9 and PARP (poly(ADP-ribose) polymerase). In addition, exposure to WELAS decreased the expression of Bcl-2 (an anti-apoptotic factor), but increased the expression of Bax (a pro-apoptotic factor), suggesting that mitochondria-dependent apoptotic pathways are mediated in WELAS-induced apoptosis. Taken together, these results indicate that water extracts of leaf of A. sylvestris inhibits cell growth and induces apoptosis via the mitochondrial-dependent apoptotic pathway in FaDu human hypopharyngeal squamous carcinoma cells. Therefore, we propose that the water extracts of leaf of A. sylvestris is a novel chemotherapeutic drug, having growth inhibitory properties and induction of apoptosis in human oral cancer cells.

This study investigated the changes of antioxidant activity and ${\alpha}$-glucosidase inhibitory effect of Jerusalem artichoke (Helianthus tuberosus) 100% methanol extracts by various heat treatment. The contents of total phenolic and flavonoid compounds in methanol extract tended to increased gradually with the rise of temperature to 180$^{\circ}C$. The maximum yield of gallic acid (51.52 ${\pm}$ 2.17mg/g extract weight) and quercetin (13.39 ${\pm}$ 0.03mg/g extract weight) were obtained with extraction temperature of 180$^{\circ}C$ for 120min. In addition, the improving extraction efficiency resulted in the increased biological activities, such as electronic donation ability (EDA, 90.36${\pm}$ 0.57%), reducing power (Abs 1.14) and ${\alpha}$-glucosidase inhibitory effect (92.14 ${\pm}$ 1.14%). Overall, the results of this study indicate that the optimum conditions for the extraction process were an extraction temperature at 180$^{\circ}C$ for 120 min, and will provide the basis for future research on the improving extraction yield of phenolic and flavonoid compounds.

This study was conducted to investigate the content of sulfur dioxide residues in medicinal herbs in Seoul in 2009. Sulfur dioxide in the samples were determined by Monnier-Williams's modified method. A total of 1,821 samples of 205 different types of herbs were collected from Kyung-Dong Herb markets and Oriental medicine hospitals in Seoul. Of these samples, 642 samples were domestic, and 1,179 samples were imported. Of the 1,821 samples, 61 (3.3%, 31 types) failed to meet the regulations for sulfur dioxide residues of KFDA in medicinal herbs. Among these 61 unsuitable samples, 17 (7 types) were domestic, and 44 samples (26 types) were imported. The content of sulfur dioxide in the domestic medicinal herbs ranged from 0 to 809 mg/kg, while those in imported medicinal herbs ranged from 0 to 4,481 mg/kg. Approximately 84.6% of the samples contained less than 10 mg/kg of sulfur dioxide and about 10.0% of samples contained more than 30 mg/kg of sulfur dioxide.

Rhizoma Coptidis, a traditional herb medicine, has been used in Korea and China for many centuries as a treatment for many disease. The purpose of the present study was to determine the effect of Rhizoma Coptidis on histamine-induced tracheal smooth muscle contraction in guinea pigs and rats. Guinea pigs(500g, male) and rats(250g, male) were killed by $CO_2$ exposure and a segment (8-10mm) of the thoracic trachea from each guinea pig was cut into equal segments and mounted 'in pairs' in a tissue bath. Contractile force was measured with force displacement transducers under 0.5g loading tension. The dose of histamine which evoked 50% of maximal response ($ED_{50}$) was obtained from cumulative dose response curves for histamine ($10^{-7}-10^{-3}M$). Contractions evoked by histamine($ED_{50}$) were inhibited significantly by Rhizoma Coptidis. The mean percent inhibition was 33.2% after 1.5mg/ml Rhizoma Coptidis, and 69.5% after 5.0mg/ml Rhizoma Coptidis in guinea pigs, and the mean percent inhibition was 25.3% after 1.5mg/ml Rhizoma Coptidis, and 65.8% after 5.0mg/ml Rhizoma Coptidis in rats. Indomethacin ($10^{-7}M$) slightly but significantly attenuated the inhibitory effects of Rhizoma Coptidis. But propranolol and methylene blue ($10^{-7}M$) did not significantly alter the inhibitory effect of Rhizoma Coptidis. These results indicate that Rhizoma Coptidis can relax histamine-induced contraction of guinea pig and rat tracheal smooth muscle, and that this inhibition involves, in part, cyclooxygenese inhibitor.

Basement membranes (BMs) are extracellular matrices associated with epithelia, endothelia, muscle, fat and peripheral nerve. They are involved in cell survival, migration, differentiation. BMs functions also include tissue formation and provide mechanical stability as a selective barriers. Laminins are heterotrimeric glycoproteins found in BMs and have a crucial role in cell adhesion and signalling. Madin-Darby canine kidney (MDCK) cells are the best established mammalian model for studying epithelial cell biology The cells form an epithelial monolayer, with tight junctions separating an apical surface from a basolateral membrane facing the filter support and neighboring cells. In this study, using MDCK cells, the synthesis of the BM protein such as laminin with or without methanol extract of Chrysanthemum morifolium (CM) stimulation was analyzed by immunoblotting and CM showed significant increased cell density and enhanced synthesis of laminin.

Objectives : The gnarl of Pinus densiflora, called Songjeol in Korea, has been used as a medicinal herb for the treatment of inflammatory-related diseases such as arthralgia, myalgia and bruise. However, the molecular actions and mechanisms have not been clearly investigated. The aim of this study was to clarify the anti-inflammatory activity of Pinus densiflora gnarl pharmacopuncture (PDGP) in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. Methods : Cytotoxicity was assessed by XTT assay. The amount of nitric oxide (NO) production was determined by nitrite assay. The mRNA expressions of interleukin-$1{\beta}$ (IL-$1{\beta}$), interleukin-6 (IL-6), cyclooxygenase-2 (COX-2) and heme oxygenase-1 (HO-1) were analyzed by RT-PCR. Reactive oxidative species (ROS) generation was measured using the fluorescence microscopy. In addition, inducible nitric oxide synthase (iNOS) and redox factor-1 (Ref-1) protein expressions were detected by Western blotting. Results : PDGP inhibited NO production and ROS generation in LPS-stimulated RAW264.7 cells. At the mRNA level, PDGP suppressed IL-$1{\beta}$, IL-6 and COX-2 expression. On the other hand, PDGP induced HO-1 mRNA expression. Furthermore, PDGP suppressed iNOS and Ref-1 protein expression. Conclusions : This result suggests that PDGP can act as a suppressor agent on NO and iNOS through induction of HO-1, and play an useful role in blocking inflammatory responses.
