  • Inhibition of cyclooxygenase(COX), and thus prevention of the formation of prostaglandins, provided a unifying explanation of the therapeutic and toxic actions of nonsteroidal anti-inflammatory drugs (NSAIDs). Recently, the discovery of the two isoforms of COX was made by molecular biologists studying neoplastic transformation in chick embryo cells. The constitutive enzyme, COX-1, is obviously responsible for the production of prostaglandins involved in housekeeping functions such as maintenance of integrity of the gastric mucosa, renal blood flow and platelet aggregation. The inducible form of COX (COX-2) is responsible for the formation of prostaglandins that pathologically affects inflammation, pain and fever. Clearly, all the experimental and clinical data support the hypothesis that the beneficial effects of NSAIDs are due to inhibition of the COX-2 enzyme, whereas the gastrotoxicity is due to inhibition of COX-1. The cox-2/COX-1 ratios of the NSAIDs in common use have been measured and compared with epidemiological data on their side effects. There is little evidence to suggest that one NSAID is clearly more effective than another, But substantial individual variability is present with respect to the pharmacology and pharmacokinetics of these drugs: therefore it is essential to adjust the dosage and choose specific drug to the patient's response.

  • Ulmus parvifolia has been used as a traditional folk medicine to treat the carbuncle in deep skin. In this study, the effect of water extract of root bark of Ulmus parvifolia (WUP) on the carbuncle, pain, inflammation and hypersensitivity was evaluated in animal models. The administration of WUP significantly decreased the size of Staphylococcus aureus ($10^8$ cells/mouse)-induced carbuncle, and also exhibited analgesic activity in the HAc-induced writhing syndrome at doses of 50-500 mg/kg. It also showed significant anti-inflammatory activity in the carageenin- and complete Freund's adjuvant-induced inflammation. In the histamine-induced anaphylaxis, it decreased the percent of mortality by protecting mice treated with Bordetella pertussis. In the immune responses in the mice sensitized and challenged with sheep red blood cells, the Arthus reaction determined by swelling of foot pad at 4 h after challenge, HA titer, HY titer and PFC which can be used to evaluate the humoral immune response were significantly suppressed by oral administration of WUP at doses of 100 and 200mg/kg. The cellular immune responses in the same mice such as delayed type hypersensitivity determined by swelling of foot pad at 24 h after challenge and RFC were also significantly suppressed in the same manner.

  • Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by abdominal pain, rectal bleeding and diarrhea. Gastrodia elata Blume (GE) has been used for the treatment of various diseases including neurodegenerative diseases and inflammatory disease. However, there has been no information on whether GE regulates intestinal inflammation. The aim of this study is to elucidate whether GE can protect against dextran sulfate sodium (DSS)-induced colitis in a mouse model. The colitis mice were induced by drinking water containing 5% DSS for 7 days. Body weight, colon length and clinical score were assessed to determine the effects on colitis. The levels of inflammatory cytokines, tumor necrosis factor $(TNF)-{\alpha}$ and interleukin (IL)-6 in colitis tissue were also measured. The results showed that mice administrated with DSS showed clinical signs including weight loss and reduced colon length. GE inhibited the DSS-induced loss of body weight and shortening of colon and increased Disease activity index score. Additionally, we observed that GE suppressed the levels of $TNF-{\alpha}$ and IL-6 in DSS-treated colon tissues. Collectively, these findings provide experimental evidence that GE might be a useful therapeutic agent for patients with UC.

  • Ohmae-hwan has been used to treat the symptoms of loose stools mixed with blood accompanied by abdominal pain due to heat dysentery in Korean medicine. However, its mechanism of action on inflammatory disease using macrophages was not known. The author was to find out about the influence of Ohmae-hwan water extract on expressions of NO, cytokine IL-6 and TNF-α in LPS-stimulated RAW 264.7 cell, on expressions of mRNA of iNOS, IL-6 and COX-2 and on suppression of expressions of protein of iNOS and COX-2, and was to find out about the mechanism. As a result of the study, it was found that Ohmae-hwan suppressed generation of NO activated by LPS depending on its concentrations, suppressed expressions of cytokine IL-6, and TNF-α and suppressed expressions of mRNA of iNOS, IL-6, and COX-2 and suppressed expressions of protein of iNOS, COX-2. Considering the above results, it can be known that Ohmae-hwan water extract has anti-inflammatory effect against inflammatory response mediated by macrophages by suppressing generation of NO, TNF-α, and IL-6 and expressions of iNOS, COX-2 as it acts on macrophages.

  • This study was performed to evaluate anti-thrombotic activities and anti-inflammatory effects of ChungyeolHaedogHwaeoTang water extract(CHHT). The results were summarized as follows. In experiment of anti-thrombotic effect; 1. CHHT inhibited human platelet aggregation induced by ADP and epinephrine as compared with the control group, and inhibited pulmonary embolism induced by collagen and epinephrine (inhibitory rate is 37.5%). 2. CHHT increased platelet number significantly, and also CHHT shortened PT and APTT significantly as compared with the control group in thrombus model induced by dextran. In experiment of anti-inflammatory effect; 3. CHHT inhibited $IL-1{\beta}$, IL-6, TNF-${\alpha}$, COX-2 and NOS-II mRNA expression as compared with the control group in a concentration-dependent degree, and inhibited NO production significantly at 50, 100 ${\mu}g/ml$, and also inhibited ROS production in a concentration-dependent degree as compared with the control of group in RAW 264.7 cell line. 4. CHHT inhibited $IL-1{\beta}$, IL-6 and TNF-${\alpha}$ production significantly in serum of acute inflammation-induced mice, and decreased $IL-1{\beta}$, IL-6 and TNF-${\alpha}$ production in spleen tissue, and also decreased $IL-1{\beta}$, and IL-6 production in liver tissue, but increased TNF-${\alpha}$ production in liver tissue of acute inflammation-induced Balb/c mice. 5. CHHT increased survival rate from the 3rd day in ICR mice with lethal endotoxemia induced by LPS. These results suggest that CHHT can be useful in treating diverse female diseases caused by thrombosis and inflammation such as menstrual pain, menstrual disorder, leukorrhea, vaginitis, cervicitis, pelvic inflammatory disease and so on.

  • Objectives : The present study investigated the anti-nociceptive and anti-inflammatory properties of the water extract of Geranii Herba (The stem and leaves of Geranium thunbergii Sieb. et Zucc.) in the animal models of pain and inflammation. Methods : We evaluated the anti-nociceptive and anti-inflammatory activities of Geranii Herba extract (GHE) using the writhing test, tail-flick test, carrageenan-induced paw edema and xylene-induced ear edema models. Two dose of GHE (100 and 1000 mg/kg) was administrated orally to the mice. Control group received normal saline and ibuprofen (50 mg/kg) was used as a positive control drug. Results : GHE 1000 mg/kg treated group showed an increased tail-flick response time in the tail-flick test and inhibitory effect on writhing syndrome induced by acetic acid. Treatment with GHE at the same dose inhibited ear edema induced by xylene and foot edema induced by carrageenan toxicity. Conclusion : The results demonstrate that GHE has anti-nociceptive and anti-inflammatory effects in the various models of nociception and inflammation.

  • Rosa rugosa Thunb, a deciduous shrub of the genus Rosa, has been widely used to treat stomach aches, diarrhoea, pain, and chronic inflammatory disease in eastern Asia. In recent years, our research team has extensively studied the Rosa rugosa flower extract, and specifically undertook pharmacological experiments which have optimized the extraction process. Our methods have yielded a standard extract enriched in phenolic compounds, named PRE. Herein, we expand our efforts and evaluated the anti-inflammatory activity of PRE on lipopolysaccharide (LPS)-induced inflammation in RAW 264.7 macrophages. PRE significantly inhibited production of nitric oxide (NO), prostaglandin $E_2(PGE_2)$, tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6, and interleukin $1{\beta}$ (IL-$1{\beta}$), as well as expression of their synthesizing enzymes, inducible nitric oxide synthase (iNOS) and cyclooxygenase2 (COX-2). Furthermore, PRE inhibited activity of mitogen-activated protein kinases (MAPK) as well as nuclear factor-kappa B (NF-${\kappa}B$) signaling pathway. Our findings are the first to explain the anti-inflammatory mechanism by PRE in LPS-stimulated macrophages. Given these results, we propose that PRE has therapeutic potential in the prevention of inflammatory disorders.

  • Root extracts of Angelica gigas and A. acutiloba have been used traditionally for the treatment of gynecological diseases, as well as anemia, blood stasis, and inflammatory pain, as blood tonics in Oriental medicine. In the present study, we investigated the effects of A. gigas and A. acutiloba on inflammatory mediators in mouse macrophages and compared their activities. Many studies suggest that prostaglandin $E_2$ ($PGE_2$) biosynthesis and nitric oxide (NO) production play important roles in the processes of both inflammation and carcinogenesis. Ethanolic extracts from the roots of both species exhibited significant inhibitory effects on $PGE_2$ generation in lipopolysaccharide-stimulated RAW 264.7 cells. In particular, the extract from A. gigas was more effective than that from A. acutiloba. Although neither inhibited NO generation, the extract from A. acutiloba stimulated NO generation. Our results suggest that the roots of A. gigas might possess more anti-inflammatory and/or cancer chemopreventative activity than that of A. acutiloba due to the suppression of cyclooxygenase-2 (COX2)-mediated $PGE_2$ production. In addition, A. acutiloba might exert anti-tumor activity through an increase in macrophage-produced NO.
