  • Objectives : Modified Gamgil-tang is a prescription commonly used for respiratory diseases. This thesis was carried out to check the treatment effects and diversity of drug formulation by comparing extraction method of ethanol and water of modified Gamgil-tang. Methods : All experiments were carried out with water and 50% ethanol extraction for comparison. In vivo experiment, hyaluronidase inhibitory effects and trypsin inhibitory effects were tested to measure the anti-inflammatory effects activity. Scavenging effects of DPPH free radical, xanthine oxidase inhibitory effects and inhibition on TBA-RS formation were experimented to measure anti-oxidative effects. With the in vivo experiment, ICR group mice and SD group rats were used as experimental animals. An anti-inflammatory effects experiment were carried out to measure the action on carrageenin-induced hind paw edema: analgesic effects were measured using writhing syndrome induced by 0.7% acetic acid in mice: antipyretic effect was measured using endotoxin, and inhibitory effects of increase vascular permeability induced by 0.5% histamine were measured. Results : For extraction of glycyrrhizin contents, ethanol extract was extracted 2 times of that of water extract. Anti-inflammatory effects showed high in ethanol extract. Anti-oxidative effects measured high in ethanol extract. No significant result was found in inhibition on TBA-RS formation. Analgesic effects were found to be similar in water and ethanol extract. Antipyretic effects were found to be stronger in water extract. Inhibitory effects of increase vascular permeability induced by 0.5% histamine showed stronger in ethanol extract. Conclusion : By measuring anti-inflammatory effects, analgesic effects, antipyretic effects, anti-oxidative effects, and histamine permeation inhibition effects both in water extract and ethanol extract after adding agents such as Mentha Herba, Gardenias Fructus, and propolis to existing Gamgil-Tang, ethanol extract was found to be more effective in anti-inflammatory effects, analgesic effects, anti-oxidative effects, and histamine permeation inhibition effects. The converse was found for antipyretic effect.

  • Recent investigations have shown that certain flavonoids, especially flavone derivatives, inhibit nitric oxide (NO) production by inducible NO synthase (iNOS) in macrophages, which contrib-ute their anti-inflammatory action. For the purpose of finding the optimized chemical structures of flavonoids that inhibit NO production, various A- and B-ring substituted flavones were syn-thesized and evaluated for their inhibitory activity using lipopolysaccharide-treated RAW 264.7 cells. It was found that the optimal chemical structures were A-ring 5,7-dihydroxyflavones hav-ing the B-ring 2',3'-dihydroxy or 3',4'-dihydroxy or 3',4'-hydroxy/methoxy (methoxy/hydroxy) groups. These structurally optimized compounds were revealed to be down-regulators of iNOS induction, but not direct iNOS inhibitors. Of these derivatives that were evaluated, 2',3',5,7-tet-rahydroxyflavone and 3',4',5,7-tetrahydroxyflavone (Iuteolin) showed the strongest inhibition. The $IC_{50}$/ values for these compounds were 19.7 and 17.1 11M, respectively. Therefore, these compounds may have a potential as new anti-inflammatory agents.

  • Objectives : TheHaedokgumhwa-sanwater extract (HDKHS) is used in Korea, Japan and China as a traditional therapeutic agent to cure an infectious disease. But its study is not enough. Therefore, the present study focused on the elucidation of HDKHS to investigate the anti-inflammatory effects and to established the possible mechanisms involved in its action on LPS-stimulated immune response in murine macrophages.Methods : Inflammatory status was induced by LPS and measured by increasement of inflammatory mediators. LPS induced secretions of NO and PGE2in RAW 264.7 cells were measured using griess reagent and enzyme-linked immunosorbent assay (ELISA) kit respectively. production of IL-6 was examined using ELISA kit and expression of IL-6 mRNA was measured by RT-PCR method. To investigate the effects of HDKHS on inflammatory mediators, such as iNOS, COX-2 and MAPKs, western blot and RT-PCR were performed.Results : HDKHS significantly reduced production of NO and PGE2 which were induced by LPS. Also, activation of IL-6 was reduced both protein and mRNA levels. The expressions of inflammatory mediator include iNOS and COX-2 were decreased by pretreatment with HDKHS. futhermore The result showed HDKHS down-regulate the LPS induced phosphorylation of ERK 1/2, one of the MAPK family, which is considered as a main regulator of transmission from pathogens to nucleus of immune cells.Conclusions : Our results suggest that the anti-inflammatory properties of HDKHS may stem from the inhibition of pro-inflammatory mediators via suppression of initiation of inflammatory response by inhibiting MAPKs signaling pathways.

  • Ginkgetin was previously reported as an inhibitor of group II phospholipase A$_2$. It also inhibited in vitro arachidonate release from the activated macrophages and lymphocyte proliferation. These previous studies suggested an anti-inflammatory nature of ginkgetin, especially on chronic inflammation. In fact, ginkgetin showed potent anti-inflammatory activity against rat adjuvant-induced arthritis, a chronic inflammatory animal model, with comparable analgesic activity. In order to investigate the action mechanisms, tumor necrosis factor and interferone release were studied from human PMMC. It was found that ginkgetin clearly inhibited release of these cytoknes from human PMMC. Ginkgetin was also found to inhibit immunoglobulin M production at 1 - 10 uM. These results may contribute to antiarthritic activity of ginkgetin in vivo.

  • Arctii Fructus (AF), which contains arctigenin (ARC) as a major constituent, is traditionally used as an anti-inflammatory medicine to treat inflammatory sore throat. Although several studies have proven its anti-inflammatory effects, there have been no reports on its use in inflammation related disorders such as obesity, cancer metastasis, and allergic responses. This study investigated the anti-obesity effect and anti-metastasis effect of AF and ARC. AF and ARC inhibited weight gain by reducing the mass of white adipose tissue in high fat diet (HFD)-induced obese mice. Serum cholesterol levels were also improved by AF and ARC. In in vitro experiments, AF and ARC decreased differentiation of white adipocytes. Furthermore, AF induced differentiation of brown adipocytes, which are able to consume surplus energy through non-shivering thermogenesis. Also, AF and ARC inhibited colon cancer and lung metastasis of colon cancer. They suppressed not only colorectal cancer cell progression by inhibiting cell growth, but also prohibited lung metastasis by regulating epithelial-mesenchymal transition (EMT), migration, and the invasion. These effects were confirmed in an experimental metastasis mouse model. In addition, AF and ARC inhibited mast cell mediated allergic responses. Collectively, our study suggests that AF and ARC might show inhibitory effects on inflammation related diseases, including obesity, cancer, cancer metastasis, and allergic responses.

  • Hyunggyeyungyotang has been used for treatment of sinusitis and otitis media in oriental medicine since ancient times. It is reported that Hyunggyeyungyotang has good effects on inflammatory and allergic diseases of otorhinolaryngology in clinical medicine. Kamihyunggyeyungyotang was made by adding several herbs to Hyunggyeyungyotang which has such good effects. To investigate the effects of Hyunggyeyungyotang and Kamihyunggyeyungyotang on inflammatory, algesic and allergic diseases, the author examined the analgesic effect by acetic acid reaction, studied the anti-inflammatory effect through the experiments of the protein thermo-denaturation and circumscribed edema. Besides researched the anti-allergic effect through the vascular permeability response to Chemical Mediator and the delayed type hypersensitivity response to Picryl Chloride. The obtained results were as follows ; 1. In the analgesic effect of Hyunggyeyungyotang and Kamihyunggyeyungyotang extract by acetic acid method, both of the sample groups showed the analgesia, but didn't show useful effect. 2. In the anti-inflammatory effect on the protein thermo-denaturation, the sample groups revealed the inhibitory effect in proportion to concentration as compared with the control group. 3. In the inhibitory action on circumscribed edema induced by Caraggeenin, both of Hyunggyeyungyotang and Kamihyunggyeyungyotang administration showed the significant effect after 4 hours in comparison to the control group. 4. In the delayed type hypersensitivity response to Picryl Chloride, both of the sample groups revealed the significant effects. 5. Both of the sample groups decreased the vascular permeability induced by Histamine in comparison with the control group, but the significancy was admitted in only Hyunggyeyungyotang administration. According to above results, Hyunggyeyungyotang and Kamihyunggyeyungyotang are considered to be used for treament of the inflammatory diseases including sinusitis.

  • Ganoderma lucidum, an oriental polypore fungus and medicinal mushroom, has a long history of use for promoting health and longevity in Korea, China, and other Asian countries. This study was aimed at determining the anti-inflammatory activity and mechanism of action of Ganoderma lucidum in murine macrophage RAW 264.7 cells. Ganoderma lucidum was extracted with ethanol and freeze-dried. The anti-inflammatory effect (nitrite production) of Ganoderma lucidum extracts was tested using a nitric oxide (NO) colorimetric assay. Semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) was performed to quantify the mRNA expression of cytokines including tumor necrosis factor-${\alpha}$ ($TNF-{\alpha}$), interleukin $(IL)-1{\beta}$, and IL-6. Western blotting was performed to measure the expression levels of inflammation-related proteins, such as inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), nuclear factor kappa B ($NF-{\kappa}B$) p65, and phosphorylated $NF-{\kappa}B$ p65. The NO colorimetric assay showed that NO production increased with the treatment of lipopolysaccharide in (LPS)-activated RAW 264.7 macrophages and decreased with the cotreatment of Ganoderma lucidum extracts and LPS. Ganoderma lucidum extracts repressed the mRNA expressions of cytokines, which were increased after the LPS treatment. In addition, Ganoderma lucidum extracts inhibited the LPS-induced expression of iNOS and COX-2 and the LPS-induced phosphorylation of $NF-{\kappa}B$ p65. These results suggest that the Ganoderma lucidum extracts exert an anti-inflammatory activity by inhibiting $NF-{\kappa}B$ related proteins and cytokines.

  • Background: Essential oils are of great interest for their analgesic and anti-inflammatory properties. We aimed to study the content of the essential oil of the Origanum vulgare of the Armenian highlands (OVA) in different periods of vegetation and to investigate its antinociceptive and anti-inflammatory effects in mice (in vivo) and cytotoxic action in cultured cells (in vitro). OVA essential oil was extracted from fresh plant material by hydro-distillation. Methods: For OVA essential oil contents determination the gas chromatography-mass spectrometry method was used. Formalin and hot plate tests and analysis of cell viability using the methyl-thiazolyl-tetrazolium (MTT) assay were used. Results: The maximal content of β-caryophyllene and β-caryophyllene oxide in OVA essential oil was revealed in the period of blossoming (8.18% and 13.36%, correspondently). In the formalin test, 4% OVA essential oil solution (3.5 mg/mouse) exerts significant antinociceptive and anti-inflammatory effects (P = 0.003). MTT assay shows approximately 60% cytotoxicity in HeLa and Vero cells for 2.0 µL/mL OVA essential oil in media. Conclusions: The wild oregano herb of Armenian highlands, harvested in the blossoming period, may be considered as a valuable source for developing pain-relieving preparations.

  • Background: Galangin, commonly employed in traditional Chinese medicine for its diverse medicinal properties, exhibits potential in treating inflammatory pain. Nevertheless, its mechanism of action remains unclear. Methods: Mice were randomly divided into 4 groups for 7 days: a normal control group, a galangin-treated (25 and 50 mg/kg), and a positive control celecoxib (20 mg/kg). Analgesic and anti-inflammatory effects were evaluated using a hot plate test, acetic acid-induced writhing test, acetic acid-induced vascular permeability test, formalin-induced paw licking test, and carrageenan-induced paw swelling test. The interplay between galangin, transient receptor potential vanilloid 1 (TRPV1), NF-κB, COX-2, and TNF-α proteins was evaluated via molecular docking. COX-2, PGE2, IL-1β, IL-6, and TNF-α levels in serum were measured using ELISA after capsaicin administration (200 nmol/L). TRPV1 expression in the dorsal root ganglion was analyzed by Western blot. The quantities of substance P (SP) and calcitonin gene-related peptide (CGRP) were assessed using qPCR. Results: Galangin reduced hot plate-induced licking latency, acetic acid-induced contortions, carrageenan-triggered foot inflammation, and capillary permeability in mice. It exhibited favorable affinity towards TRPV1, NF-κB, COX-2, and TNF-α, resulting in decreased levels of COX-2, PGE2, IL-1β, IL-6, and TNF-α in serum following capsaicin stimulation. Galangin effectively suppressed the upregulation of TRPV1 protein and associated receptor neuropeptides CGRP and SP mRNA, while concurrently inhibiting the expression of NF-κB, TNF-α, COX-2, and PGE2 mRNA. Conclusions: Galangin exerts its anti-inflammatory pain effects by inhibiting TRPV1 activation and regulating COX-2, NF-κB/TNF-α expression, providing evidence for the use of galangin in the management of inflammatory pain.

  • Background: Korean Red Ginseng (KRG) is a representative traditional herbal medicine with many different pharmacological properties including anticancer, anti-atherosclerosis, anti-diabetes, and anti-inflammatory activities. Only a few studies have explored the molecular mechanism of KRG-mediated anti-inflammatory activity. Methods: We investigated the anti-inflammatory mechanisms of the protopanaxadiol saponin fraction (PPD-SF) of KRG using in vitro and in vivo inflammatory models. Results: PPD-SF dose-dependently diminished the release of inflammatory mediators [nitric oxide (NO), tumor necrosis factor-${\alpha}$, and prostaglandin $E_2$], and downregulated the mRNA expression of their corresponding genes (inducible NO synthase, tumor necrosis factor-${\alpha}$, and cyclooxygenase-2), without altering cell viability. The PPD-SF-mediated suppression of these events appeared to be regulated by a blockade of p38, c-Jun N-terminal kinase (JNK), and TANK (TRAF family member-associated NF-kappa-B activator)-binding kinase 1 (TBK1), which are linked to the activation of activating transcription factor 2 (ATF2) and interferon regulatory transcription factor 3 (IRF3). Moreover, this fraction also ameliorated HCl/ethanol/-induced gastritis via suppression of phospho-JNK2 levels. Conclusion: These results strongly suggest that the anti-inflammatory action of PPD-SF could be mediated by a reduction in the activation of p38-, JNK2-, and TANK-binding-kinase-1-linked pathways and their corresponding transcription factors (ATF2 and IRF3).
