Objectives : Draconis Resina (DR), the resin of Daemonorops draco Bl., is used to circulate the blood and to stop bleeding. It also has been used to generate flesh including ulceration. The present study investigated the effects of DR extract on collagen metabolism in human fibroblasts and tyrosinase activity in mushroom tyrosinase.Methods : The effect of DR extract on type I procollagen production (collagen type I synthesis) and collagenase (matrix metalloproteinase-1, henceforth referred as MMP-1) activity in human normal fibroblasts cell line. Hs68 cells after ultraviolet B (UVB, 312 nm) irradiation was measured using the enzyme - linked immunosorbent assay (ELISA). The tyrosinase activity was also measured to find out the whitening effects in mushroom tyrosinase by ELISA method.Results : There was no cytotoxicity at DR extract at concentrations of 10 μg/ml, 30 μg/ml, and 100 μg/ml. DR extract significantly inhibited the increase of collagenase activity, whereas it did not show on the reduction of type I procollagen in UVB damaged Hs68 cells. DR extract did not reduce the L - DOPA oxidation. However, it significantly reduced the tyrosinase activity by DR extract at concentraions of 0.1 mg/ml, 1 mg/ml and 10 mg/ml.Conclusions : In conclusion, DR showed the anti-wrinkle and whitening effects via the inhibition of collagenase production and the tyrosinase activity. These results suggest that DR may have potential as an anti-aging ingredient in cosmetic herb markets.

Objectives : Rosa laevigata Michx. has been used for the treatment of renal disease in traditional Korean medicine. In this study, we investigated cytoprotective effect of R. laevigata water extract (RLE) against oxidative stress induced by arachidonic acid (AA) + iron.Methods : To evaluate the protective effects of RLE against AA + iron-induced oxidative stress in HepG2 cell, cell viability and changes on apoptosis-related proteins were assessed by MTT and immunoblot analyses. The effects of RLE on reduced glutathione level, production of reactive oxygen species and mitochondrial membrane potential were also monitored. Furthermore, to verify underlying molecular mechanism, NF-E2-related factor 2 (Nrf2) was examined by immunoblot analysis. Additionally, Nrf2 transactivation and its downstream target genes expression were also determined by reporter gene and realtime RT-PCR analyses.Results : RLE pretreatment (30-300 μg/ml) prevented cells from AA + iron-mediated cell death in a concentration dependent manner. In addition, 100 μg/ml RLE inhibited AA + iron-induced glutathione depletion, reactive oxygen species production and mitochondrial dysfunction. RLE accumulated nuclear Nrf2 and also transactivated Nrf2, which was evidenced by antioxidant response element- and glutathione S-transferase A2-driven luciferase activities and mRNA level of glutamate-cysteine ligase catalytic subunit, NAD(P)H:quinone oxidoreductase 1 and sestrin 2. Moreover, protective effect of RLE against AA + iron was abolished in Nrf2 knockout cells.Conclusions : These results indicate that RLE has the ability to protect hepatocyte against oxidative stress through Nrf2 activation.

Objectives : Persicaria tinctoria belongs to the Polygonaceae family and it has been used as the natural dye traditionally. Also, it is well known that the Persicaria tinctoria is used for treating the following symptoms such as fever, inflammation and edema. The purpose of this study is to investigate the effective source of antioxidants and anti-inflammatory agent from various parts of Persicaria tinctoria.Methods : We investigated the antioxidative and anti-inflammatory properties of the Persicaria tinctoria extracts. Antioxidant activities were measured by 1,1-diphenyl-2- picrylhydrazyl (DPPH), 2, 2`-Azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) radical scavenging activity, Fe
chelating activity and Reducing power of Persicaria tinctoria extracts. And its inhibitory effect against oxidative DNA damage was evaluated in non-cellular system using φX-174 RF I plasmin DNA. The anti-inflammatory effect of Persicaria tinctoria was measured by using the inhibitory efficacy for the amount of nitric-oxide (NO) produced in LPS induced RAW264.7 cells.Results : The extracts from stem part showed better DPPH scavenging activity compared to those of the leaf and root extracts. Their IC
s were measured as 7.17, 144.40 and 165.07 ug/ml, respectively. These results were similar to that of ABTS radical scavenging assay and reducing power. Also, Persicaria tinctoria showed the protective effects of DNA damage against oxidative stress and anti-inflammatory effect by suppression of NO production in LPS induced RAW264.7 cells.Conclusions : These results showed that various parts of Persicaria tinctoria can be used as an effective source of antioxidants and anti-inflammatory agents via antioxidative activities and anti-inflammatory effect.

Objectives : The purpose of this study was to investigate the endothelium-dependent vasorelaxation effect of Cynomorii Herba(CH) extract on contracted rabbit carotid artery.Methods : To clarify the vasorelaxation effect of CH extract, arterial strips with intact was used, to endothelium -dependent vasorelaxation effect of CH extract, arterial strips damaged endothelium was used for experiment using organ bath. Arterial strips was contracted with phenylephrine(PE) before treated with CH extract(0.01, 0.03 and 0.1 ㎎/㎖). To study mechanisms of CH-induced vasorelaxation effect, CH extract infused into arterial rings after treatment by indomethacin(IM), tetraethylammonium chloride(TEA), Nω-nitro-L-arginine (L-NNA), methylene blue(MB) for comparing with non-treated. And calcium chloride(Ca
) 1 mM was treated into precontracted arterial ring induced by PE after treatment of CH extract in Ca
-free krebs solution. Cytotoxic activity of CH extract on human umbilical vein endothelial cell(HUVEC) was measured by MTT assay, and nitric oxide(NO) concentration was measured by Griess reagent.Results : PE-induced arterial strips was significantly relaxed, but the damaged endothelium arterial ring wasn`t relaxed by CH extract. Pretreatment of IM, TEA didn`t inhibit the vasorelaxation of CH extract, but pretreatment of L-NNA, MB inhibited the vasorelaxation of CH extract. Pretreatment of CH extract reduced the increase of contraction by influx of extracellular Ca
in contracted arterial ring induced by PE, CH extract increased nitric oxide concentration on HUVEC significantly.Conclusions : This study shows that CH extract have the vasorelaxation effect by blocking the influx of extracellular Ca
through the activating NO-cGMP system.

DOI : 10.6116/kjh.2015.30.6.33.
Objectives : Portulaca oleracea (PO) have been used as a traditional medicine to treat inflammatory diseases in Korea. However, the anti-inflammatory effect of PO ethanol extract on lipopolysaccharide (LPS)-induced inflammation is not well-known. Therefore, this study was performed to identify the anti-inflammatory effect of PO on LPS induced inflammatory.Methods : Identification of PO was conducted by comparison with purified standards by HPLC. To measure out the cytotoxicity of PO, author performed the MTT assay. To evaluate the anti-inflammatory effects of PO, author examined the inflammatory mediators such as nitric oxide (NO) and pro-inflammatory cytokines (tumor necrosis factor (TNF)-α, interleukin, (IL)-1β and IL-6) on RAW 264.7 cells. Author also examined molecular mechanisms such as mitogen-activated protein kinases (MAPKs) and nuclear factor-B (NF-κB) activation by western blot.Results : Three major components (peaks 1, 2, 3) were detected in both varieties and peak 1 was characterized as caffeic acid, peak 2 as p-coumaric acid, and peak 3 as ferulic acid by comparison of chromatographic properties with authentic standards. Extract from PO itself did not have any cytotoxic effect in RAW 264.7 cells. PO inhibited LPS-induced productions of inflammatory mediators such as NO and pro-inflammatory cytokines in RAW 264.7cells. In addition, PO inhibited the phosphorylation of extracellular signal-regulated kinase1/2 (ERK1/2), c-Jun NH
-terminal kinase (JNK) and NF-κB activation in RAW 264.7 cells.Conclusions : Above experiment data can be an important indicator for the identification of PO and this study suggest that treatment of PO could reduce the LPS-induced inflammation. Thereby, PO could be used as a protective agent against inflammation.

Objectives : The aim of this study was to evaluate the effect of Schizonepeta Spica water extract (SS) on the OVA-induced BLAB/c mice allergic rhinitis model.Methods : Thirty two BALB/c mice were equally assigned to 4 groups; the sham group, the control group, the cetirizine hydrochloride (Cet) treatment group, and the SS treatment group. Sham group was sensitized and challenged with saline, and the other groups were sensitized and challenged with OVA. The dosage of SS was 7.6 mg /kg·day, and Cet was 10 mg/kg·day. Nasal rubbing and sneezing were measured by the behavior observation. The concentrations of IL-1β, IL-10, TNF-α and MIP-2 in the sera of allergic rhinitis model were measured by mouse cytokine/chemokine magnetic bead panel kits. Total IgE and OVA-specific IgE were measured by ELISA method. Epithelial thickness and eosinophil infiltration of nasal septum was investigated by histological examination.Results : The clinical symptoms that increased in control group were significantly reduced in SS-treated group. Serum total IgE and OVA-specific IgE in the SS-treated group were significantly reduced compared to the control group. The concentration of IL-1β, IL-10, TNF-α and MIP-2 in SS-treated group showed a significant reduction compared to the control group. The infiltration of eosinophil into nasal tissues of SS-treated group decreased markedly compared to control group, and thickness of nasal septum in nasal mucosa showed a significant reduction compared to control group.Conclusions : According to the above result, it is suggested that SS may inhibit the early and late phase of allergic rhinitis reaction.

Objectives : This study was performed to investigate the anti-diabetic effect of the fruit extract of Lycium chinense Mill(Lycii Fructus, LF) on multiple low-dose streptozotocin-induced diabetic rats.Methods : Male Sprague-Dawley rats were divided into three groups; normal, STZ-control, Lycii Fructus extractorally administrated 300 ㎎/㎏ group (STZ-LF). Diabetes was induced in rats by consecutive injection of streptozotocin (STZ) at doses of 30 ㎎/㎏ for 5 days. After 4 weeks, all rats were sacrificed, Fasting blood glucose, total cholesterol (CHO), triglyceride (TG) and HDL-Cholesterol were measured in sera of rats. Histopathological changes of pancreas, kidney, liver and lung tissues were observed by microscope after H&E, Periodic acid-Schiff (PAS) and Masson`s trichrome staining. The changes of body weight, blood glucose, and food and water intake were also measured.Results : There were no differences in body, food intake and water intake in LF-administrated groups compared with STZ control group. However, LF extract significantly decreased the levels of serum glucose, CHO, TG and HDL-Cholesterol in diabetic rats. In histopathological analysis of kidney, liver and lung, LF-administrated groups showed the inhibition of morphological damage.Conclusions : These results suggest that LF have a biological action on multi low-dose STZ-induced diabetes in rats via decreasing the serum glucose, TG and TG levels and may protect the morphological changes of kidney, liver and lung.

DOI : 10.6116/kjh.2015.30.6.55.
Objectives : Yongdamgosam-hwan(YGH) has been used as a traditional medicine from old times for antiinflammatory effects. Streptococcus mutans(S. mutans) is known as a prime bacteria responsible for causing caries by forming a biofilm referred to as dental plaque on the tooth surface. But antimicrobial activity of YGH with dental disease is not sufficiently understood. This study was designed to investigate the effects of YGH ethanol extract on antimicrobial effect against Streptococcus mutans.Methods : The antimicrobial effect of YGH ethanol extract was assessed by the paper disk diffusion method and optical density method to determine minimum inhibition concentration(MIC), also observed by fractional inhibitory concentration index(FICI) and time-kill assay to figure out the synergic effect on the combination of YGH ethanol extract with antibiotics.Results : The YGH ethanol extract 500 μg was 7.5-8.5 mm diameter of clear zone of inhibition against Streptococcus mutans in a concentration-dependent manner and MIC was 250 μg/mL. The administration of the ethanol extract in combination with gentamicin and streptomycin induced a reduction of ≥4-8-fold in all tested bacteria. Furthermore, time-kill study was found that a combination of YGH ethanol extract with oxacillin and streptomycin produced a more rapid decrease in the concentration of bacteria CFU/mL than the YGH ethanol extract or antibiotics alone.Conclusions : As a result, the YGH ethanol extract has good antimicrobial effects. And the results suggest that YGH could be employed as a natural antibacterial agent in dental care products.

Objectives : Gastric lesions affect many people around the world and their development are results of the imbalance between destructive and protective factors in the gastric mucosa. Lycium chinense has been widely used as a traditional Korean medicine, it was recently reported that they have potent anti-inflammatory effects in chronic hepatitis models. Therefore, this study aimed to investigate the anti-inflammatory activity of Lycium chinense extract (LCE) on HCl-Ethanol induced gastric lesion mice.Methods : The ICR mice were divided randomly into five groups of six animals each. Group A was normal mice, and group B was treated orally with 0.5 ml 150 mM HCl-60% Ethanol. Mice in group C and D were pre-treatment of LCE (100 mg/kg and 200 mg/kg bodyweight, p.o before HCl/ethanol treatment) and group E was orally administered sucralfate (10 mg/kg).Results : 150mM HCl/60% ethanol-induced gastric mucosal injury mice were ameliorated mucosal damage upon histological evaluation by treatment of LCE. Pre-treatment of LCE attenuated reactive oxidative species (ROS) and produces peroxynitrite (ONOO
) in stomach tissues. As results of stomach protein analyses, LCE effectively reduce inflammatory-related factors such as cyclooxygenase-2 (COX-2), tumor necrosis factor alpha (TNF-α), inducible nitric oxide synthase (iNOS) and interleukin-6 (IL-6) in gastric lesion mice. In addition, nuclear factor kappa B (NF-κB) and inhibitor of phosphorylation of nuclear factor kappa B (p-IκB) were down-regulated in LCE-administrated gastric lesion mice.Conclusions : Our discovery supports that the therapeutic activity of LCE ameliorate the development of gastric lesion via suppressing the oxidative stress and gastric partial inflammation induced by 150 mM HCl/60% ethanol.

DOI : 10.6116/kjh.2015.30.6.69.
Objectives : This study was designed to investigate effects of the combination with Korean Red Ginseng (Panax ginseng C.A. Meyer), Gastrodia Rhizoma (Gastrodia elata Blume) and Polygoni Multiflori Radix (Polygonum multiflorum Thunberg) on metabolic disorders including cholesterol and erectile dysfunction in hyperlipidemia rats.Methods : Animals were divided into six groups; Control with normal diet, high fat/cholesterol-diet (HFCD), fluvastatin, Korean Red Ginseng treated (KRG), and the combination treated (Korean Red Ginseng, Gastrodia Rhizoma and Polygoni Multiflori Radix; 1:1:1 for KGP1 and 2:1:1 for KGP2). The experimental groups initially received HFCD for 10 weeks and then treated orally with fluvastatin, KRG, KGP1 and KGP2 during the final 6 weeks. Erectile function was determined by the measurements of intracavernosal pressure (ICP) and maximal arterial pressure (MAP) after electrical stimulation of the cavernosal nerve.Results : KGP2 decreased the level of total cholesterol and LDL cholesterol in the sera of HFCD rats without no changes of body weights. KRG, KGP1 and KGP2 decreased the level of C-reactive protein (CRP) levels except of fluvastatin, synthetic HMG-CoA reductase inhibitor. KRG, KGP1 and KGP2 significantly increased the ICP, ICP/MAP ratio, area under the curve (AUC) compared with those of normal rat. Morphometric analyses showed that KRG, KGP1 and KGP2 increased the volume of smooth muscle and the regular arrangement of collagen fibers in corpus cavernosum of HFCD rats. The penile expression of eNOS was increased by KRG, KGP1 and KGP2.Conclusions : Based on these results, we suggest that the combination with Korean Red Ginseng, Gastrodia Rhizoma and Polygoni Multiflori may improve hyperlipidemia through regulating the lipid profiles and erectile dysfunction in rats.

DOI : 10.6116/kjh.2015.30.6.77.
Objectives : This study was designed to investigate of the anti-inflammatory effects of Schisandra chinensis seed oil(SSO) on the production of pro-inflammatory substances in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages.Methods : SSO was measured the production of pro-inflammatory factor (NO, PGE2, IL-1β iNOS and, COX-2) in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. we used the following methods : cell viability assay, Griess reagent assay, enzyme-linked immunosorbent assay, Western blotting analysis.Results : The cell viability of SSO(0∼500 μl/mL) processing group was 96.9% and the processing of SSO didn`t have an effect on the cytotoxicity. The inhibitory effect of the nitric oxide (no) production of SSO(500 μg/mL, 50 μg/mL, 10 μg/mL) was each 70.3%, 37.6% and 26.5%. IL-1β production inhibition ability of SSO(500 μg/mL, 100 μg/mL) was each 49.88% and 48.8%. PGE2 production inhibition ability of SSO(500 μg/mL, 100 μg/mL) was each 49.88% and 73.1%, 70.5%. By using SSO, it experimented about iNOS protein expression inhibition ability, that is the NO production enzyme. iNOS protein expression increased in the group processing LPS independently. iNOS protein expression decreased in the group processing SSO together. The expression of the COX-2 protein decreased 89.6%, 81.8% in the group processing SSO. The significance was in the relationship with NO formation inhibition with the relationship with the PGE
formation inhibition and iNOS protein, it confirmed in SSO with the COX-2 protein.Conclusions : Stimulation of the RAW 264.7 cells with LPS caused an elevated production of nitric oxide (NO), IL-1β and PGE
which was markedly inhibited by the pretreatment with SSO without causing any cytotoxic effects. The reduced expressions of iNOS protein were consistent with the reductions in NO production in the culture media. SSO may be useful for the treatment of various inflammatory diseases.

DOI : 10.6116/kjh.2015.30.6.83.
Objectives : The present study was conducted to examine whether Cynanchi wilfordii radix (CWR) with or without fermentation has an ameliorative effect on hyperlipidemia in rats.Methods : We analyzed the contents of Conduritol F on Cynanchi wilfordii radix. The experimental animals were divided into six groups; normal diet fed group (N), high cholesterol fed control group (Con), Lovastatin 20 mg/kg (L), CWR-W 300 mg/kg (CWR-W), and CWR-F 300 mg/kg on hyperlipidemia model induced by feeding 1.25% cholesterol. Rats were administrated orally every day for 8 weeks. And lipid profile of serum and weight change were observed.Results : The vehicle displayed a markedly increased body weight and significantly increased liver and epididymal fat weight, however, the administration of CWR improved the body, liver, and epididymal fat weights. All drug treatment reduced significantly the serum level of total cholesterol and LDL-cholesterol elevated by intake of high cholesterol diet. TG displayed a reducing tendency all drug treatment, however, CWR-W decreased significantly. Atherogenic index and cardiac risk factor increased high cholesterol diet fed control group, while the administration of CWR-W and CWR-F decreased significantly. The major index of liver injury such as AST and ALT improved in all drug treatment.Conclusions : These results suggest that CWR extended the effect of lipid enhanced. Therefore CWR with or without fermentation may be useful for therapeutic treatment of clinical conditions associated with hyperlipidemia. Finally, these require more investigations about the action mechanism of CWR in the future.
