These studies were conducted to investigate the antiinflammatory effects and the mechanism of action of natural products. We used the methods of "carrageenan induced foot edema" , "PAF (platelet activating factor) induced foot edema" , "inhibition test of vascular permeability" , "inhibition test of white blood cell migration" , "formation of granuloma" and "adjuvant induced arthritis" to examine the antiinflammatory erects of Angelica gigas, Ledebouriella seseloides, Ginkgo biloba and Bamboo salt (Jukyom). The oral administration of the water extract of Angelica gigantis radix, the methanolic extract of Ginkgo folium and the aqueous solution of Bamboo salt showed antiinflammatory effect on carrageenan and PAF induced foot edema in SD rat at a dose of 1 g/kg. The same administration of methanolic extract of Ginkgo folium also inhibited the vascular permeability in mice. The aqueous solution of Bamboo salt inhibited the formation of ganuloma in SD rats at a oral dose of 1 g/kg. Angelica gigantis radix seems to have antiinflammatory effect by inhibition of PAF.

Ssangwhatang which has been known to have antipyretic, analgesic and antifatigue effects are composed of Paeoniae Radix, Angelicae gigantis Radix, Astragali Radix, Rehmaniae Radix, Cnidii Rhizoma, Cassiae Cortex, Glycyrrhizae Radix and Puerariae Radix. Effects of some formulations of Ssangwhatang were studied with respect to the analgesic, antipyretic, hypothermic, anticonvulsive and antiinflammatory actions in experimental animals. The results obtained were as follows: 1) Prescription A, B, C and D of Ssangwhatang were showed significant analgesic effect by the acetic acid stimulating method in mice. 2) All Ssangwhatang-prescriptions used in this studies had hypothermic effect in normal mice. 3) Significant antipyretic effect in febrile rabbits were recognized in prescription A and C of Ssangwhatang, while not in prescription B and D of Ssangwhatang. 4) Prescription A, B, C and D of Ssangwhatang showed marked antiinflammatory effect against the edema induced by carrageenin in rats. 5) Prescriptions of Ssangwhatang did not show significant anticonvulsive effect against the convulsion induced by picrotoxin and strychnine in mice. From the above results, analgesic, hypothermic, antipyretic and antiinflammatory effects were recognized in Ssangwhatang. Ssangwhatang A- and C- prescriptions added with Pueraiae Radix showed better effects than prescription B and C of Ssangwhatang.

Flavonoids are widely distributed polyphenol compounds in plant kingdom and known to possess varieties of biological/pharmacological activities in vitro and in vivo. A search for antiinflammatory/immunoregulatory flavonoids as potential therapeutic agents has been continued, since serious side effects of currently used nonsteroidal and steroidal antiinflammatory drugs limit their long term uses for the inflammatory disorders. In this reserch, various flavonids were isolated and tested for their in vivo antiinflammatory activity and in vitro inhibitory activity of lymphocyte proliferation. Using a mouse ear edema assay, it was found that certain flavones/flavonols possess mild antiinflammatory activity and a C-2,3-double bond might be essential. Isoflavones were less active. These flavonoids inhibited in vitro lymphocyte proliferation, relatively specific for T-cell proliferation $(IC_{50}=1-10\;{\mu}M)$ and the inhibition was reversible. We have also tested several biflavonoid derivatives, since we recently found that biflavones were phospholipase $A_2$ inhibitors. It was demonstrated that biflavones such as ochnaflavone and ginkgetin inhibited lymphocyte proliferation induced by both concanavaline A and lipopolysaccharide. The inhibition was irreversible in contrast to that of flavones/flavonols. And antiinflammatory activity of biflavonoids are discussed.

4-Pivaloyloxy, 4-benzenesulfonyloxy and 4-p-toluenesulfonyloxy compounds of piroxicam (2a, 2b and 2c) and isoxicam(4a, 4b and 4c) were synthesized in fairly good yield. Antiinflammatory and ulcerogenic effects of the 6 compounds were determined. Antiinflammatory effect of 2a was comparable to that of piroxicam and ulcerogenic effect of 2a was less than that of piroxicam.

The authors investigated drug interaction of ibuprofen and prednisolone in antiinflammatory and antipyretic activities. We have found significant differences of the antiinflammatory and antipyretic activities between single and concurrent administration of ibuprofen and prednisolone, using Sprague-Dawley Strain rats, carrageenin as a phlogistic agent and brewer's yeast as a fever inducing agent. 1) Ibuprofen(20mg/kg) was administered to the rats orally and resulted in significant reduction of (31.70 %) the swelling of rat paw induced by carrageenin, 2) prednisolone (9mg/kg) showed significant reduction of (45.76%) the swelling, 3) concurrent administration of ibuprofen (20mg/kg) and prednisolone (9mg/kg) also reduced (57.40%) the swelling. In ibuprofen (125mg/kg) administration, the inhibition rate of edema was 39.32% and in prednisolone (1mg/kg) administration, the rate was 39.04%. In concurrent administration of ibuprofen (125mg/kg) and prednisolone (1mg/kg), the inhibition rate of edema was 63.09%. Concurrent administration of ibuprofen and prednisolone showed more anti-inflammatory effects than single administration of ibuprofen and prednisolone respectively. Prednisolone itself did not show antipyretic effect, but concurrent administration of ibuprofen and prednisolone showed more antipyretic effects than ibuprofen single administratron.

Background: Ginseng has a wide range of beneficial effects on health, such as the mitigation of minor and major inflammatory diseases, cancer, and cardiovascular diseases. There are abundant data regarding the health-enhancing properties of whole ginseng extracts and single ginsenosides; however, no study to date has determined the receptors that mediate the effects of ginseng extracts. In this study, for the first time, we explored whether the antiinflammatory effects of Rg3-enriched red ginseng extract (Rg3-RGE) are mediated by retinoid X receptor ${\alpha}$-peroxisome-proliferating receptor ${\gamma}$ ($RXR{\alpha}-PPAR{\gamma}$) heterodimer nuclear receptors. Methods: Nitric oxide assay, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazoliumbromide assay, quantitative reverse transcription polymerase chain reaction, nuclear hormone receptor-binding assay, and molecular docking analyses were used for this study. Results: Rg3-RGE exerted antiinflammatory effects via nuclear receptor heterodimers between $RXR{\alpha}$ and $PPAR{\gamma}$ agonists and antagonists. Conclusion: These findings indicate that Rg3-RGE can be considered a potent antiinflammatory agent, and these effects are likely mediated by the nuclear receptor $RXR{\alpha}-PPAR{\gamma}$ heterodimer.

This study was undertaken to evaluate the antinociceptive and antiinflammatory effects of the heartwood extract of Rhus verniciflua (Anacardiaceae) and the two major components, sulfuretin and fustin. The MeOH extract, its EtOAc-soluble portion and sulfuretin showed significant antinociceptive activity in writhing and hot plate test assays and antiinflammaory effects in carrageenan-induced hind paw edema in rats. In particular, treatment of sulfuretin with 10 mg/kg dose (i.p.) reduced writhing frequency by 48.0% (p<0.01) compared to that of a control group. Further, the treatment of sulfuretin (5, 10 mg/kg, i.p.) for 7 days prevented the carrageenan-induced hind paw edema significantly (p<0.01). The antiinflammatory effect of sulfuretin was also confirmed by microscopic observation of mast cell numbers in muscle. In addition, sulfuretin suppressed the cyclooxygenase- 2 (COX-2) activity $(IC_{50}\;=\;28.7\;{\mu}M)$ in lipopolysaccharide-activated macrophage cells. This result indicates that the inhibitory effect of sulfuretin on COX-2 may be one of the antinociceptive/antiinflammatory mechanism.

As an attempt to search for bioactive natural constituents exerting antinociceptive and antiinflammatory activities, we examined the potency of the extract of R. coreanus fruits by the activity-guided fractionation. The EtOAc- and BuOH fraction and those alkaline hydrolysates showed significant antinociceptive effects as assessed by writhing-, hot plate- and tail flicks tests in mice and rats as well as antiinflammatory effect in rats with carrageenan-induced edema. BuOH extract was subjected to column chromatography to obtain a large amount of niga-ichigoside F$_1$ (1, 23-hydroxytormentic acid 28-O-glc), which was again hydrolyzed in NaOH solution to yield an aglycone 23-hydroxytormentic acid (1a).
