This study was presented to the physiological activities such as metal chelating capacity, superoxide dismutase-like activity, anti-inflammation, cytotoxicity from Zanthoxylum schnifolium fruit. The values for metal chelating capacity of 1 mg/mL of 70% EtOH and 70% MeOH extracts were 68% and 67%, respectively, it was shown that metal chelating capacity in a dose-dependent manner. The 100% EtOH and 100% MeOH extract exhibited strong superoxide dismutase-like activity. The highest SOD-like activity obtained from 100% EtOH was 51% at a concentration of 4 mg/mL. The all extracts of Zanthoxylum schnifolium fruit except $H_2O$ extract significantly decreased the concentration of LPS-induced NO in Raw 264.7 cells. The 100% EtOH, 100% MeOH and 70% EtOH extract represented the highest activity in the anti-inflammation properties in vitro. However, the 100% EtOH and 100% MeOH extracts has cytotoxicity in Raw 264.7 cells and it may affect cell viability. Conclude that 70% EtOH extract was most suitable for anti-inflammation. Our results revealed that the Zanthoxylum schnifolium fruit expected to physiological activities.

This study was carried out to investigate whether asian yellow sand dust (AS) has promoting effects of allergen-related airway inflammation and airway hyperresponsiveness, because the number of patient with allergic asthma and atopy, and with chronic bronchial inflammation and pneumonia have increased steadily in the cities of Korea. The appearance of AS collected was all round and flat, and the diameter was mostly below about 5 ${\mu}m$. When mice were treated with AS suspension by intratracheal instillation combined with ovalalbumin(OVA) sensitization chronically, the level of serum L-lactate dehydrogenase (LDH), IgE and histamine, and respiratory resistance was increased. Intratracheal instillation of AS and OVA also enhanced infiltration of eosinophils in the bronchoalveolar lavage fluid (BALF), IgE and eotaxin expression, and T helper type 2 cell derived cytokines of interleukin (IL)-4, IL-13 and IL-5 as major contributors to allergy and asthma. These results indicate that AS elevates allergen-related airway inflammation and airway hyperresponsiveness in mice and may play an important role in the aggravation of respiratory diseases in Korea.

Elsholtzia splendens Nakai has been used in North-East Asia as an ingredient of folk medicines for treating cough, headache and inflammation. The present investigation was carried out to establish its in vivo anti-inflammatory activity using several animal models of inflammation and pain. The 75% ethanol extract of the aerial part of E. splendens significantly inhibited mouse croton oil-induced, as well as arachidonic acid-induced, ear edema by oral administration (44.6% inhibition of croton oil-induced edema at 400 mg/kg). This plant material also showed significant inhibitory activity against the mouse ear edema induced by multiple treatment of phorbol ester for 3 days, which is an animal model of subchronic inflammation. In addition, E. splendens exhibited significant analgesic activity against mouse acetic acid-induced writhing (50% inhibition at 400 mg/kg), while indomethacin (5 mg/kg) demonstrated 95% inhibition. E. splendens ($5-100{\;}{\mu}g/mL$) significantly inhibited $PGE_2$ production by pre-induced cyclooxygenase-2 of lipopolysaccharide-treated RAW 264.7 cells, suggesting that cyclooxygenase-2 inhibition might be one of the cellular mechanisms of anti-inflammation.

The aim of our study is to investigate the anti-nociceptive and anti-inflammatory properties of an ethanol extract of the leaf and stem of Aralia cordata. Writhing responses induced by acetic acid, tail immersion test, and formalin-induced paw pain response for nociception and formalin-induced paw edema for inflammation were evaluated in mice. A. cordata (50 - 200 mg/kg, p.o.) and ibuprofen (100 mg/kg, p.o.), a positive non-steroidal anti-inflammatory drugs (NSAIDs), inhibited the acetic acid-induced writhing response, but they did not protect the thermal nociception in tail immersion test. However, morphine (5 mg/kg, s.c.) used as positive opioid control alleviated both the acetic acid-induced writhing response and thermal nociception in tail immersion test. In the formalin test, A. cordata (50 - 200mg/kg) and ibuprofen (200mg/kg) inhibited the second phase response (peripheral inflammatory response), but not the first phase response (central response), whereas morphine inhibited both phase pain responses. Both A. cordata (100 mg/kg) and ibuprofen (200 mg/kg) significantly alleviated the formalin-induced increase of paw thickness, the index of inflammation. These results show for the first time that the leaf and stem of A. cordata has a significant anti-nociceptive effect that seems to be peripheral, but not central. A. cordata also displays an anti-inflammatory activity in an acute inflammation model. The present study supports a possible use of the leaf and stem of A. cordata to treat pain and inflammation.

Methods : The cytotoxicity of Sulfur extract about viability of Raw 264.7 cell were tested using a colorimetric tetrazolium assay(MTT assay). To investigate the anti-inflammation effects of Sulfur extract on LPS-induced macrophage Raw 264.7 cell, we used ELISA kit and Western blots. We evaluated anti-oxidation effects of Sulfur extract on HaCaT cell by Enzyme recycling method. And we investigated the inhibitory effects of Sulfur extract on Propionibactrium acnes using paper disk diffusion method. Results: 1. Sulfur extract has a little cytotoxicity in Raw 264.7 cell. 2. Concentration of $100\;{\mu}g/m{\ell}$ Sulfur extract inhibited the production of NO in the Raw 264.7 cell stimulated with LPS. 3. Sulfur extract showed a oxidation inhibition effect by decreasing the DPPH radicals. 4. Sulfur extract has not the significant inhibition effect of Propionibactrium acnes. Conclusions: These results indicate that Sulfur extract has anti-inflammation and anti-oxidation effects. If further study is performed, the use of Sulfur extract will be valuable and benificial in the therapy of Propionibactrium acnes.

Prostaglandins biosynthesis and nitric oxide production have been implicated in the process of inflammation and osteoarthritis. And nitric oxide (NO) activated the MMPs responsible for PG degradation in articular chondrocytes. Therefore, we have studied the effects on anti-inflammation and analgesic by ethyl acetate fraction from 70% ethanol extract of Perilla Frutescens (EPF). EPF inhibited LPS plus inflammation-cytokines-induced proteoglycan (PG) degradation, matrix-metalloproteinase (MMP-2,9) expression in rabbit articular chondrocytes. Also, EPF have inhibitory effects on LPS or LPS plus inflammation cytokines-induced nitric oxide (NO) and PGE2 production in mouse macrophage andrabbit articular chondrocytes. These results suggest that EPF decreases PGE2, iNOS, MMPs activity and PG degradation in mouse macrophage and/or rabbit articular chondrocytes. In vivo, EPF was shown to have inhibitory effects on acetic acid-induced pain. The herbal extract with this profile, may have utility in the treatment of osteoarthritis.

Chronic low-grade inflammation is associated with obesity. This study investigated effect of high hydrostatic pressure extract of red ginseng (HRG) on inflammation in rats with high-fat (HF) diet induced obesity. Male, Sprague-Dawley rats (80~110 g) were randomly divided into two groups, and fed a 45% HF diet (HF) and a 45% HF diet containing 1.5% HRG (HF+HRG) for 14 weeks. At the end of the experiment, the serum leptin level was reduced by the HRG supplementation. The mRNA expression of genes related to adipogenesis including peroxisome proliferator-activated receptor-gamma and adipocyte protein 2 was down-regulated in the white adipose tissue (WAT). The mRNA levels of major inflammatory cytokines such as tumor necrosis factor-${\alpha}$, monocyte chemoattractant protein 1, and interleukin-6 were remarkably down-regulated by the HRG in WAT. These results suggest that HRG might be beneficial in ameliorating the inflammation-associated health complications by suppressing adipogenic and pro-inflammatory gene expression.

Bee venom has been clinically used to control the pain of inflammation disease etc. in general. Although the effect of bee venom herbal acupuncture has been reported, its mechanism has not been fully elucidated yet. Free radical metabolism seems to occupy a remarkably common position in the mechanisms of inflammation and ageing related disease. Oxidative damage to DNA, lipids, proteins and other molecules may contribute to the development inflammation disease. NO or DPPH is one of the free radicals and a mediator in inflammation diseases. The objective of this study is to investigate the scavenging effect of bee venom herbal acupuncture against NO and DPPH. The followings are the summary of the results: (1) There is no significant scavenging effect of bee venom herbal acupuncture on NO in BVS and BVP group. (2) There is a significant scavenging effect of bee venom herbal acupuncture on DPPH in BVS-1 and BVP-1 group. These results suggest that bee venom herbal acupuncture can be used for inflammation diseases such as rheumatoid arthritis. This study would provide important basic data on the possibility of the clinical treatment of bee venom herbal acupuncture. Further studies are required to investigate the antioxidative effects of it.

This study was designed to find some potential natural products and/or constituents inhibiting proinflammatory cytokine generation in lung inflammation, since cytokines such as tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and interleukin-6 (IL-6) are pivotal for provoking airway inflammation. In our preliminary screening procedure, the 70% ethanol extract of the leaves of Perilla frutescens (PFE) was found to clearly inhibit TNF-${\alpha}$ production in the lung at 100 mg/kg, after intranasal lipopolysaccharide treatment of mice. Based on this result, ten constituents including phenylpropanoids (allyltetramethoxybenzene, caffeic acid, dillapiole, elemicin, myristicin, nothoapiole, rosmarinic acid methyl ester, rosmarinic acid) and monoterpenes (perilla aldehyde and perilla ketone) were successfully isolated from the extract. Among them, elemicin and myristicin were found for the first time to concentration-dependently inhibit IL-$1{\beta}$-treated IL-6 production from lung alveolar epithelial cells (A549) at concentrations of $10-100{\mu}M$. These findings suggest that the phenylpropanoids including elemicin and myristicin have the potential to be new inhibitory agents against lung inflammation and they may contribute, at least in part, to the inhibitory activity of PFE on the lung inflammatory response.

We previously showed that the water extracts of rice wine-baked Scutellaria baicalensis Georgi (RWBS) ameliorated colonic inflammation more than crude Scutellaria baicalensis (CS) after oral administration. The aim of this study is to compare the effect of rectal and oral administration of RWBS in the experimental colitis. Experimental colitis was induced in mice by daily treatment with 5% dextran sulfate sodium (DSS) in the drinking water for 7 days. Water was used as vehicle of oral administration, while Carbopol/PEG mucoadhesive gel was used as vehicle of rectal administration. RWBS and RWBS gel (RWBSG) were administered once per day for 7 days. RWBS and RWBSG significantly attenuated the disease activity index (DAI) calculated as the sum of scores of body weight loss, stool consistency and rectal bleeding. Furthermore, RWBS and RWBSG reduced the mucosal myeloperoxidase activity and COX-2 (cyclooxygenase-2) expression in colon tissue. Anti-inflammatory effect of CS on colonic inflammation was increased by baking with rice wine in both oral and rectal administration. Moreover, anti-inflammatory effects of oral administration on colonic inflammation was greater than those of rectal administration. Further study would be required for the development of intra-rectal formulation.
