Hoechunyanggyeok-san (HYS) is a traditional oriental herbal medicine widely used for treating inflammatory disorders. Although there are numerous clinical results of HYS reported in the literature of oriental hebal medicine, it has been rarely conducted to evaluate the immuno-biological activity. The present study was conducted to examine the anti-inflammatory effects of HYS extract (HYSE) in vivo and in vitro. To determine the cytotoxic concentration of HYSE, cell viability was tested by MTT assay. All four doses of HYSE (0.01, 0.03, 0.10 and 0.30 mg/ml) had no significant cytotoxicity during the entire experimental period. In order to measure NO levels in culture medium, the cells were treated with $1\;{\mu}g/ml$ of LPS 1h before adding HYSE for 24 h and then culture medium were reacted with Griess reagent. Increased NO production and iNOS expression were detected in LPS-activated cells compared to control. However, these increases were dose-dependently attenuated by treatment with HYSE. LPS plays a key role in leading to the massive production of pro-inflammatory cytokines such as TNF-$\alpha$, IL-$1{\beta}$ and IL-6 in macrophages. Thus, we next determined the levels of these cytokines. HYSE reduced the elevated production of TNF-$\alpha$, IL-$1{\beta}$ and IL-6 by LPS. Moreover, the effects of HYSE were in a dose-dependent manner. In vivo, histopathological study, HYSE effectively inheefed the increases of hind paw skin thicknesses and inflammatory cell infiltrations induced by carrageenan treatment. It, therefore, considered that HYSE will be favorably inheefed the acute edematous inanner. In s. These findings showed that HYSE could have anti-inflammatory effects through the reduction of NO and inflammatory cytokines in macrophage. Furthermore, the reduction of carrageenan-induced paw oedema by HYSE helps to understand its actions on inflammatory conditions.

Objectives : In the present study, the effect of electroacupuncture (EA) applied to SI6 and won-rak point on the ankle sprain model was examined. A common source of persistent pain in humans is the lateral ankle sprain. Methods : To model this condition, the rat's right ankle was bent repeatedly, overextending lateral ligaments, for 4 min under enflurane anesthesia. The rat subsequently showed swelling of the ankle and a reduced stepping force of the affected limb for the next several days. The reduced stepping force of the limb was presumably due to a painful ankle. EA was applied to the several acupuncture point on the contralateral forelimb for 30 min under gaseous anesthesia. After the termination of EA, behavioral tests measuring stepping force and Paw volume were Periodically conducted during the next 4 h and 18 h respectively. Results : EA applied to $SI_6$ with won-rak point produced more powerful improvement of stepping force of the sprained foot than to $SI_6$ alone lasting for at least 4 h. However, neigher $KI_4$ point nor $BL_{64}$ point produced any significant increase of weight bearing force. The improvement of stepping pressure was interpreted as an analgesic effect. The analgesic effect was specific to the acupuncture point since the analgesic effort on the ankle sprain pain model could not be mimicked by EA applied to $KI_4$ or $BL_{64}$. In addition, EA applied to $SI_6$ with won-rak combination point showed inhibitory effect on the paw edema induced by ankle sprain. Also, COX-2 protein expression increased by ankle sprain were suppressed by the EA stimulation. Conclusion : These data suggest that EA with won-rak combination point produces a more potent analgesic effect on the ankle sprain pain model in the rat and that EA with won-rak combination point induced anti-inflammatory effect through the suppression of COX-2 protein expression.

Objectives : This study was performed to investigate the effects of Gamichangbaek-san(Jiaweichangbai-san) on anti-inflammatory, analgesic, anti-febrile and immune response on the arthritis of carrageenan-induced animals. Methods and Materials : Rats were classified into control and sample groups which are 7 individuals each for the experiments about anti-inflammatory and anti-febrile. Each of the 7 mice were classified into normal, control, sample groups for the analgesic experiments. Gamichangbai-san(Jiaweichangbai-san) was administered to sample group and normal saline was administered to normal and control groups. Arthritis was induced by injection of 1% carrageenan $0.1m{\ell}$ and Gamichangbaek-san(Jiaweichangbai-san) was administered after 30 minutes. The change of edema in Carrageenan-induced Arthritic Rats' Paws was measured after 1 hour and 5 hours from the injection of carraqeenan with Plethysmometer(7150, UGO BASILE, ltaly) by Winter' method. WBC, Lymphocyte and ESR were measured by heart puncture and CD4+ T cell, CD8+ T cell and CD4+/CD8+ T cell ratio were measured from the spleen tissue. Writhing syndrom was measured with Tail flick unit(UGO BASILE, Italy) in the experiments conducted to check the analgesic activity. The temperature of the paws of carrageenan-induced arthritic rats was measured by Laser thermometer. Rectal temperature was measured by Yeast's method in anti-febrile experiments. Immune response was measured by CD4+, CD8+ T cell ratio and CD4+/CD8+ T cell ratio. Results : 1. It was recognized that Gamichangbaek-san(Jiaweichangbai-san) decreased the increase rate of Paw Edema effectively with statistical significance. 2. It was recognized that Gamichangbaek-san(Jiaweichangbai-san) decreased WBC, Lymphocyte and ESR with statistically high significance. 3. It was recognized that Gamichangbaek-san(Jiaweichangbai-san) did not show significant analgesic effect, but the Pressure pain threshold of the paws was increased with statistical significance. 4. It was recognized that Gamichangbaek-san(Jiaweichangbai-san) decreased rectal temperature effectively and had an anti-febrile effect about the febrile of a joint with statistical significance. 5. It was recognized that Gamichangbaek-san(Jiaweichangbai-san) increased CD4+ T cell ratio with statistically high significance and increased CD+8 T cell ratio with statistical non significance but increased CD4+/CD8+ T cell ratio effectively with statistical significance, too. Conclusions : According to the above results, it can be concluded Gamichangbaek-san(Jiaweichangbai-san) showed the treatment effects on the artificial arthritis resulted from carageenan in rats and it is suggested that more interest and study in the security for the clinical use were needed.

Previous screening of the pharmacological action of Gastrodia elata (GE) root (Orchidaceae) showed that methanol (MeOH) extracts have significant anti-inflammatory properties. The antiinflammatory agents of GE, however, remain unclear. In this experiment, MeOH extracts of GE were fractionated with organic solvents for the anti-inflammatory activity-guided separation of GE. Eight phenolic compounds from the ether (EtOEt) and ethyl acetate (EtOAc) fractions were isolated by column chromatography: 4-hydroxybenzaldehyde (I), 4-hydroxybenzyl alcohol (II), benzyl alcohol (III), bis-(4-hydroxyphenyl) methane (IV), 4(4'-hydroxybenzyloxy)benzyl-methylether (V), 4-hydroxy-3-methoxybenzyl alcohol (VI), 4-hydroxy-3-methoxybenzaldehyde (VII), and 4-hydroxy-3-methoxybenzoic acid (VIII). To investigate the anti-inflammatory and anti-oxidant activity of these compounds, their effects on carrageenan-induced paw edema, arachidonic acid (AA)-induced ear edema and analgesic activity in acetic acid (HAc)-induced writhing response were carried out in vivo; cyclooxygenase (COX) activity, reactive oxygen species (ROS) generation in rat basophilic leukemia (RBL 2H3) cells and 1,1-diphenyl-2-picryl-hydroazyl (DPPH) scavenging activity were determined in vitro. These phenolic compounds not only had anti-inflammatory and analgesic properties in vivo, but also inhibited COX activity and silica-induced ROS generation in a dose-dependent manner. Among these phenolic compounds, compound VII was the most potent anti-inflammatory and analgesic. Compound VII significantly inhibited silica-induced ROS generation and compound VI significantly increased DPPH radical scavenging activity. Compounds I, II and III significantly inhibited the activity of COX-I and II. These results indicate that phenolic compounds of GE are anti-inflammatory, which may be related to inhibition of COX activity and to anti-oxidant activity. Consideration of the structure-activity relationship of the phenolic derivatives from GE on the anti-inflammatory action revealed that both C-4 hydroxy and C-3 methoxy radicals of benzyl aldehyde play an important role in anti-inflammatory activities.

Phallus impudicus var. impudicus L. is an edible mushroom that has long been used as folk medicine in China. The aim of this study was to evaluate the antioxidant, anti-cholinesterase, and inflammation inhibitory activities of a methanol extract of fruiting bodies of P. impudicus var. impudicus L. The extract exhibited good 1,1-diphenyl-2-picrylhydrazyl scavenging activity, excellent ferrous ion chelating activity, and moderate hydroxyl radical scavenging activity compared with BHT at 2.0 mg/ml. However, the reducing power of the extract was significantly lower than that the BHT positive control. Although the inhibitory activities of methanol extract on acetylcholinesterase and butyryl cholinesterase were significantly lower than the galanthamine positive control at the concentration tested, the inhibition of acetylcholinesterase and butyryl cholinesterase was 52.83% and 55.17%, respectively, at 1.0 mg/ml. The methanol extract also demonstrated excellent inhibition of inflammation-related activities, such as production of nitric oxide in lipopolysaccharide-induced RAW 264.7 macrophage cells and acute edema induced by administration of carrageenan on the hind paw of rats. The collective results suggest that the fruiting body of P. impudicus var. impudicus L. might be a good source of antioxidant, anti-cholinesterase, and anti-inflammation compounds.

Sophoricoside was isolated as the inhibitor of IL-5 bioactivity from Sophora japonica (Leguminosae). It has been reported to has an anti-inflammatory effect on rat paw edema model. To develope as an anti-allergic drug, genotoxicity of sophoricoside was investigated in bacterial and mammalian cell system such as Ames bacterial reversion test, chromosomal aberration assay and single cell gel electrophoresis (Comet) assay. As results, in the range of 1,250~40 $\mu\textrm{g}$/plate sophoricoside concentrations was not shown significant mutagenic effects in Salmonella typhimurium TA 98, TA 100, TA 1535 and TA 1537 strains in Ames test. The 80% cell growth inhibition concentration (IC/SUB 80/) of sophoricoside was determined as above 5,000 $\mu\textrm{g}$/$m\ell$ in Chinese hamster lung (CHL) fibroblast cell and L5178Y mouse lymphoma cell line for the chromosomal aberration and comet assay, respectively. Sophoricoside was not induced chromosomal aberration in CHL fibroblast cell at concentrations of 700, 350 and 175 $\mu\textrm{g}$/$m\ell$ or 600, 300 and 150 $\mu\textrm{g}$/$m\ell$ in the absence or presence of S-9 metabolic activation system, respectively. Also, in the comet assay, the induction of DNA damage was not observed in L5178Y mouse lymphoma cell line both in the absence or presence of S-9 metabolic activation system. From these results, no genotoxic effects of sophoricoside were observed in bacterial and mammalian cell systems used in these experiments.

Objective : Based on the immunological dysfunction in RA and the immunological feature of Clematis mandshurica Maxim. herbal acupuncture solution (CM-HAS), this study examined whether subcutaneous (s.c.) administration of CM-HAS has anti-inflammatory effects on adjuvant arthritis (AA) in the rat. Methods : Complete Freund's adjuvant was used to induce AA in rats. Secondary paw swelling of AA rats was measured, and polyarthritis index was scored. The administration of CM-HAS (2, 5, 10 mg/kg) to the Sinsu-hyul (BL 23) acupuncture point subcutaneously (s.c.) inhibited the inflammatory response and restored the weight of body and immune organs of AA rats. In this study. inhibitory effect of CM-HAS on cyclooxygenase-2 (COX-2) was evaluated. The plant material selected for this study has been used in Korean medicine for the treatment of various diseases that are considered as inflammatory in nature, e.g. asthma, arthritis, rheumatism, fever, edema, infections, snakebite and related inflammatory diseases. Results : There were significant secondary inflammatory reactions in AA rats, accompanied with the simultaneous decrease of body and immune organs weight. The administration of CM-HAS (2, 5, 10 mg/kg, s.c.) improved the above changes significantly. CM-HAS showed inhibitory activity against COX-2, which supports their traditional uses. In this study, aspirin and indomethacin were used to contrast with CM-HAS as the COX-2 inhibitors. Conclusion: The findings of this study may explain at least in part why CM-HAS has been traditionally used for the treatment of inflammatory conditions in traditional Korean and Chinese medicine.

This study was carried out to know the effects of sopunghwalhyeoltang-gamibang(hereinafter referred to SPHHT) on the inhibition of arthritis induced by collagen on the mouse. Various experimental were performed in vivo (in DBA/1 J mice which are experimental model of arthritis induced by collagen) to analyse the immunomodulatory effects of SPHHT. The results were obtained as follows: 1. The cytotoxicity against mLFC was not measured in all concentration. 2. The arthritis index, incidence, hind paw edema, delayed-type hypersensitivity reaction, spleen weight were reduced in SPHHT treated group. 3. The expression of CD3 ε +/CD4+, CD3 ε +/CD8+ and CD19+ in peripheral blood mononuclear were reduced in SPHHT treated group. 4. The production of pro-inflammatory cytokines such as IL-6 and TNF-α were significantly reduced in SPHHT treated group. 5. The formation of new bones and synivium were stimulated in SPHHT treated group. Comparison of the results for this study showed that Sopung-hwalhyeoltang-gamibang had immunomodulatory effects. So we expect that Sopunghwalhyeoltang-gamibang should be used as a effective drugs for not only rheumatoid arthritis but also another auto-immune disease. Therefore we have to survey continuously in looking for the effective substance and mechanism in the future.
