  • The flowers of Lonicera japonica Thunb. (Caprifoliaceae) has been used as anti-inflammatory drug in the folk medicine recipe and been proved its anti-inflammatory effect in the oriental medicine. However, the action mechanism of Lonicera japonica that exhibits anti-inflammatory effects has not been determined. Since nitric oxide (NO) is one of the major inflammatory parameter, we studied the effect of aqueous extracts of Lonicera japonica (AELJ) on NO production in lipopolysaccharide (LPS)-stimulated mouse peritoneal macrophages. NO and inducible NO synthase (iNOS) level were significantly reduced in LPS-stimulated macrophages by AELJ compared to those without Electrophoretic mobility shift assay (EMSA) indicated that AELJ blocked the activation of nuclear factor kappa B (NF-kB), which was considered to be a potential transcription factor for the iNOS expression. AELJ also blocked the phosphorylation and degradation of inhibitor of kappa B-alpha (IkB-${\alpha}$). Furthermore, IkB kinase alpha (IKK${\alpha}$), which is known to phosphorylate serine residues of IkB directly, is inhibited by AELJ in vivo and in vitro. These results suggest that AELJ could exert its anti-inflammatory actions by suppressing the synthesis of NO through inhibition of NF-kB activity.

  • 본 연구에서는 한약 재료로 널리 이용되고 있는 3종의 약용식물(지치, 창이자, 인동초)을 기능성 소재로 이용하기 위하여 총 페놀함량, DPPH radical 소거능, xanthine oxidase 저해능 등의 실험을 통해 한약재의 항산화 활성을 살펴보았다. 지치, 창이자, 인동초의 수율은 각 7.01%, 2.92%, 7.95%, 총 페놀함량은 각 $4.3{\pm}0.1{\mu}g/ml$, $5.4{\pm}0.1{\mu}g/ml$, $4.6{\pm}0.1{\mu}g/ml$를 함유하고 있었다. DPPH radical 소거능은 인동초가 0.24 mg/ml에서 $EC_{50}$이 나타났으며 나머지 2종 모두 높은 DPPH radical 소거능을 보였다. Xanthine oxidase 저해능은 0.01 mg/ml의 농도에서 한약재 3종 모두 대조구로 사용된 ascorbic acid보다 더 높은 저해 활성을 나타내었다. 그 외에도 Superoxide radical 소거활성은 지치와 인동초가 50 mg/ml의 농도에서 80% 이상의 소거활성을 보였으며, OH radical 소거활성은 50 mg/ml의 농도에서 40% 이상의 소거활성이 나타났다. 이상의 결과로부터 지치, 창이자, 인동초 모두 높은 항산화 활성을 가지고 있으며, 기능성 소재로 활용 가능함을 확인하였다.

  • The objective of this study was to covering of vine the traffic noise barrier and analyse of their growth characteristics. For the purpose of the experiments, chosen were 28 plants. In January 1996 to December 1998, the nursery seedbeds on the Chonju Arboretum in Korea Highway Corporation were seeding and cutting with those species, and a few species were carried out Honam Highway field experiments. The results are summarized as follows ; The germination ratio of seedbed experiments were Wisteria floribunda(88%), Lonicera japonica(86%), Parthenocissus tricuspidata, Paederia scandens(85%), Celastrus orbiculatus(76%), Clematis terniflora var. denticulata(52%), Clematis mandshurica(44%) respectively.

  • Broussonetia papyrifera and Lonicera japonica have long been used in the treatment of inflammatory disorders, especially respiratory inflammation, in Chinese medicine. Previously, phytoformula (BL) containing B. papyrifera and L. japonica was found to exert strong anti-inflammatory activity in vitro and in vivo. In this study, the effects of BL on lung inflammation including bronchitis were examined in vitro and in vivo. BL (10-100 ${\mu}g$/ml) inhibited nitric oxide (NO) production of lipopolysaccharide (LPS)-treated alveolar macrophages, MH-S cells, primarily by down-regulating inducible NO synthase. BL also inhibited production of the proinflammatory cytokines, TNF-${\alpha}$ and IL-6. Against an animal model of pleural cavity inflammation, BL (200-400 mg/kg) significantly inhibited 5 h and 24 h carrageenan-induced pleurisy in rats when administered orally. Additionally, BL inhibited experimental bronchitis induced by intratracheal instillation of LPS to rats. Taken together, these results indicate that BL may be effective for the treatment of human lung inflammation as well as bronchitis.

  • Lonicera japonica has been widely used for chronic inflammatory diseases in many Asian countries. Its analgesic effect has not been explored yet. This study aimed to test the analgesic potential of methanol extracts from Lonicera japonica (MELJ) in rat neuropathic mctel. Neuropathic pain was pacts ed by partial sciatic nerve injury. Two weeks after surgery, neuropathic rats received oral administration of MELJ at doses of either 0.0 g/kg, 0.2 g/kg or 0.4 g/kg. At dose of 0.0 g, rats were administered with saline only and used as conracl. The behavioral tests for f 0.0 g, raand ccld hs were adma were weformed up to 2 hours after treatment. The MELJ at the dose 0.4 g/kg dmg gfg, ntly alleviated f 0.0 g, rahyperalgesia, but not cold hyperalgesia. These results showed that the MELJ had, although transient, analgesic effect on mechanical hyperalgesia in the rat neuropathic model.

  • Lonicera japonica Thunb. is a twining shrub that has been used as an antidote and to treat urinary disorders, fever and headache. It has been known as an anti-inflammatory agent in Korea from ancient times and is used widely for treating upper-respiratory tract infections, diabetes mellitus and rheumatoid arthritis. In the previous research, we isolated several flavonoid derivatives from the EtOAc soluble fraction. (omitted)

  • Lonicerae Folium et Caulis, the folium and stem of Lonicera japonica Thunb., has been used as diuretic, stomachic, antipyretic, analgesic and anti-inflammatory agent in Korea. We isolated a main iridoid, loganin which has some important biological effects from the folium and stem of this plant. Generally, it is known that iridoid compounds have variable contents by the collecting time and a part of plant. The content of main compound is important to evaluate its quality. In order to evaluate the quality of Lonicerae Folium et Caulis, the method of quantitative determination of loganin as a reference standard compound has been developed. (omitted)

  • Objectives : This study was to investigate the anti-oxidative and anti-inflammatory effect of Lonicera japonica water extracts (LE) on Ulcerative Colitis Induced by DSS (Dextran Sulfate Sodium) in Mice. Methods : Colitis was induced by DSS in Balb/c mice. The sample group was divided into three. The mice in control group were not inflammation-induced. The pathological group was composed of untreated colitis elicited mice. The experimental group was administered Lonicera japonica water extracts (LE) after colitis elicitation. The effects on ulcerative colitis were evaluated the anti-oxidant effect, inhibition of COX-2 mRNA expression, the morphological change of colonic mucosa, decrease effect of HSP 70 and COX-2 in mucosa. Results : The SOD ability of LE was dose-dependently increased and the LPS-induced COX-2 mRNA expression of LE was dose-dependently decreased. LE showed the protective effects on DSS-induced experimental colitis. LE inhibited shortening of colon length, the hemorrhagic erosion in colonic mucosa. LE also showed the decrease effect for HSP70 and COX-2 in mucosa. Conclusions : The current results demonstrate the clinical utility of LE in traditional medicine and indicate the possible treatments for ulcerative colitis from natural products. Further investigations for exact mechanisms will be needed.

  • Lonicera japonica Thunb.(Caprifoliaceae) has long been known as an anti-inflammatory. In the present study, the effect of water fraction of Lonicera japonica (LJ) on trypsin-induced mast cell activation was examined. HMC-1 cells were stimulated with trypsin (100 nM) in the presence or absence of LJ (10, 100, and 1000 $\mu$ g/mL). TNF-$\alpha$ and tryptase production were measured by enzyme-linked immunosorbent assay (ELISA) and reverse transcription-PCR. Extracellular signal-regulated kinase (ERK) phosphorylation was assessed by Western blot. Trypsin activity was measured by using Bz-DL-Arg-p-nitroanilide (BAPNA) as substrate. LJ (10, 100, and 1000 $\mu$g/mL) inhibited TNF-$\alpha$ secretion in a dose-dependent manner. LJ (10, 100, and 1000 $\mu$g/mL) also inhibited TNF-$\alpha$ and tryptase mRNA expression in trypsin-stimulated HMC-1. Furthermore, LJ inhibited trypsin-induced ERK phosphorylation. However, LJ did not affect the trypsin activity even 1000 $\mu$g/mL. These results indicate that LJ may inhibit trypsin-induced mast cell activation through the inhibition of ERK phosphorylation than the inhibition of trypsin activity.
