This study for developing a new anti-inflammatory medicine was sought by investigating the antiinflammatory properties of C. indicum L. extract. Rats were treated with either saline (control) or C. indicum L. extract and then injected with LPS. We found that the plasma concentration of IL-1${\beta}$ IL-6, TNF-${\alpha}$and IL-10 peaked at 5h after LPS injection, and the plasma concentration of IL-6 and TNF-${\alpha}$ showed a tendency to decrease, and IL-10 concentration showed a tendency to increase with increasing levels of C. indicum L. extract. In the liver concentration of cytokines at 5 h post LPS injection, IL-1${\alpha}$ and IL-6 decreased with increasing concentration of C. indicum L. extract, however TNF-${\alpha}$ and IL-10 did not differ significantly the treatment groups.

Arginine deiminase (ADI, E.C. 3.5.3.6), one of the arginine deprivation enzymes, exhibits anticarcinogenic activities. The present study investigated the anti-inflammatory activities of the purified recombinant ADI originating from Lactococcus lactis ssp. lactis ATCC7962 (LADI). LADI dose-dependently inhibited lipopolysaccharide (LPS)-induced upregulation of inducible nitric oxide synthase and the production of nitric oxide in RAW 264.7 murine macrophages. The induction of cyclooxygenase-2 expression and subsequent production of prostaglandin $E_2$ by LPS was also attenuated by LADI treatment. Moreover, LADI inhibited the production of interleukin-6 in LPS-stimulated RAW 264.7 macrophages. These results indicate that LADI exerts anti-inflammatory effects, which may in part explain its chemopreventive potential.

These studies were conducted an attempt to investigate effects of 'Paeryungtang' and 'Kamipaeryungtang' water extracts on diuretic, antipyretic, antiinflammatory and analgesic actions. The results of these studies were summarized as follows; Increase in urinary volume, urinary $Na^+$ excretions were significantly recognized in normal rat. Increase in urinary volume, urinary $Na^+\;and\;Cl^-$ excretions were significantly shown in rat with 2mg/kg $HgCl_2$-induced acute renal failure. Antipyretic, anti-inflammatory and analgesic effects of 'Paeryungtang' and 'Kamipaeryungtang' were recognized in mice, rats and rabbits.

Phytochemical investigation of the roots of Echiochilon fruticosum resulted in the isolation of two naphthoquinone derivatives. Compound 1 was identified as anhydroalkanin while compound 2 was identified as a new derivative 5-hydroxy 8-methoxy 2-(4-methylpent-1,3-dienyl) naphthalene-1,4-dione named as echiochiloquinone. In addition, caffeic acid 3, caffeic acid methyl ester 4 were isolated. The structures were determined by physical, chemical and spectral methods. The anti-inflammatory activity of the root extracts and compound 2 was evaluated utilizing both cotton pellet-induced and carragenin-induced rat paw edema. The ulcerogenic effect was also studied.

The aim of this study is to elucidate the anti-inflammatory activities of chopi (Zanthoxylum piperitum A.P. DC.) essential oil. Essential oil (EO) of chopi was extracted by steam distillation method, and its major constituents were limonene and geranyl acetate. Chopi-EO decreased approximately 38% of nitrite production, as compared to the lipopolysaccharde (LPS)-induced nitrite production. However, chopi-EO and its components did not quench nitric oxide (NO) chemically in cellfree system, and markedly inhibited approximately 40.4% of inducible nitric oxide synthase (iNOS) mRNA transcription. In addition, the inhibition of E-selectin gene transcription by chopi-EO caused the suppression of cellular adhesion. These results suggest that chopi-EO may exert potential anti-immunological inflammatory activity.

ln order to develope anti-inflammatory glucocorticoids for local use without systemic side-effects, ester and amide derivatives of 20$\xi$-dihydroprednisolonic acid have been prepared. When binding affinities of these compounds to glucocorticoid receptor of rat liver cytosol were compared, all a-isomer at C-20 showed higher binding affinities than the corres¬ponding $\beta$-isomer. The size of the substituents at C-21 had significant influences on binding affinities, which were related with their lipophilicity.

Sakuranetin, prunetin and dihydroquercetin were isolated from the methanol extract of Sorbus commixta by 1D/2D-NMR and LC-MASS spectrometry. Medicating these compounds to RAW264.7 cell that was pre-treated by lipopolysaccharide revealed anti-inflammatory effects that greatly inhibited the production of NO (nitric oxide) and PEG2 (prostaglandin E2), which are well known to cause the expression of iNOS (inducible nitric oxide synthase) and COX-2 (Cyclooxygenase-2). These results suggest that these compounds can be used as stable anti-inflammatory materials.

Dichloromethane, ethanol, and boiling water extracts of the brown alga Ecklonia cava were examined in vivo for their antipyretic, analgesic, and anti-inflammatory activities in mice. These activities were evaluated by yeast-induced pyrexia, tail-flick test, and phorbol myristate acetate-induced inflammation (edema, erythema, and blood flow). Ethanol extract of E. cava (0.4 mg/ear) inhibited the inflammatory symptoms of mouse ear edema, erythema, and blood flow by 82.6%, 69.0%, and 65.4%, respectively. This extract also demonstrated potent analgesic activity. No acute toxicity was observed after p.o. administration of each extract (5 g/kg bw). These in vivo data are in agreement with the claims of the health care industry and indigenous medicine that E. cava is an effective remedy for inflammation-related symptoms.

The anti-inflammatory and analgesic actions of Cedrela sinensis, Oenanthe javanica and ARtemisia princeps var. orientalis were carried out. The methanolic extract of Artemisia princeps var. orientalis showed the inhibitory effect on carrageenin-induced edema as well as vascular permeability in mice. And we also found the alagesic activity in these plants.

This paper presents anti-inflammatory effects of nonsteroidal anti-inflammatory drugs and their copper complexes, and the change of content of copper in serum, liver, brain and edema foot induced by 1% carrageenan in rats, and also investigation of stomach hemorrhage. The results were as follows. 1. The content of copper decreased in liver and brain, however, the concentration of copper significantly increased in serum and edema site after carrageenan injection in rats. 2. The content of copper in serum and edema site was decreased after administration of anti-inflammatory drugs. 3. Edema inhibition rate of aspirin was, higher than that of copper (II) aspirinate, but edema inhibition rate of copper complex of naproxen was markedly higher than that of naproxen. 4. Hemorrhage of stomach of copper salicylate was higher than that of sodium salicylate, but hemorrhage of stomach of sodium naproxen was higher than that of copper naproxen.
