The studies on the anti-inflammatory and analgesic activities were carried out to develop the domestic natural sources of the underground parts of Caragana koreana Nakai (Leguminosae), which have been used for the treatment of neuralgia, arthritis, and gout etc. in folk remedies. The methanol extract of the root was shown significant antiinflammatory effect in the paw edema induced by carrageenin, and also indicated remarkable preventive and therapeutic effects to chronic arthritis model induced by Freund's complete adjuvant in rats. It also has inhibited significantly the increase in vascular permeability and the number of writhings induced by acetic acid in mice.

Bioactivity guided phytochemical study of the petroleum ether and butanol extracts of Clematis hirsuta resulted in the isolation of 12 compounds. Rat paw edema as a model of acute inflammation was used to evaluate the anti-inflammatory activity of the extracts and the chromatographic fractions. Five known sterols and triterpenes namely: ${\beta}-amyrin$ (1), lupeol (2), ${\beta}-sitosterol$ (3), oleanolic acid (4) and stigmasterol glycoside (5) were isolated from the petroleum ether extract. The n-butanol extract afforded two compounds reported for the first time from natural source: (S)-(+)-dihydro-5-(hydroxymethyl)-2(3H)-furanone (7) and (s)-(-)-5-hydroxymethyl-2(5H)-furanone (8). In addition, anemonin (6), dihydro-4-hydroxy-5-(hydroxymethyl)-2(3H)-furanone (2-deoxy-D-ribono-1,4-lactone) (9), biophenol (cimidahurin) (10), glucose (11) and sucrose (12) were also identified. The structures were determined from spectroscopic data including 1D- and 2D-NMR experiments.

A new phenol and hydrazide derivatives were obtained for the first time from the C. giganteawhite by silica gel column chromatography. The structure of the isolated compounds was identified by UV, IR NMR and MS. C. gigantea was scientifically reported for several medicinal properties viz. analgesic, antimicrobial and cytotoxic. In this screening work, anti-microbial activity of test compounds was found to be active against all organisms. Additionally, anti-inflammatory activity of the test groups has reduced the thickness of edema of the hind paw compared to the control group.

Sophoricoside was isolated as the inhibitor of IL-5 bioactivity from Sophora japonica (Leguminosae). It has been reported to have 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 test, chromosomal aberration assay and single cell gel electrophoresis (Comet) assay.(omitted)

The recombinant gamma-interferon (LBD-001) which was produced by yeast as host system was investigated on the pharmacological activities. This gamma-interferon exhibited potent inhibitory effect on adjuvant induced arthritis, but no effect on carrageenin induced paw edema in rats. It did not show any sedative, anticonvulsive, analgesic and hypothermic activities in animals. It also had no influences on isolated tracheal muscle and ileum of guinea pig, isolated uterus and fundus strip of rats, and on blood pressure and respiration in situ experiments of rabbits.

A series of structurally diverse amide derivatives of [6-(3,5-dimethyl-4- chloro-pyrazole-1-yl)-3(2H)-pyridazinone-2-yl]acetic acid were prepared and tested for their in vivo analgesic and anti-inflammatory activity by using p-benzoquinone-induced writhing test and carrageenan induced hind paw edema model, respectively. The analgesic and anti-inflammatory activity of the compounds, 7c, 7d and 7k were found to be equipotent to aspirin (as an analygesic) and indometacin (as an anti-inflammatory drug), respectively. The other amide derivatives generally resulted in lower activity on comparision with reference compounds.

Propolid (bee-glue), known as a folk medicine, is a lipo;hilic material found in honeybee hives. In the present study on the anti-inflammatory effect of Korean propolis, it was extracted with ethanol, and used as a test material. The $LD_{50}$ value with the oral administration of ethanolic extract of Korean propolis (EEKP) was higher than 2g/kg in mice. The oral administration of the propolis extract (100mg/kg) significantly inhibited the development of hind paw edema induced by carrageenin in rats. the oral pretreatment of the propolis extract markedly inhibited the increase in vascular permeability and the number of writhing induced by acetic acetic acid in mice. Propolis extract, 50 and 100 mg/kg p.o. per day for 7 days, produced a significant inhibitory effect on granuloma and exudate formation in rats. This inhibitory effect was enhanced with the concomitant use of prednisolone (2.5 mg/kg). These results suggest that Korean propolis apparently has a strong anti-inflammatory activity.

In this study, a series of new $N^2$ substituted 1,2-dihydro-3H-indazol-3-ones (3a-d) as well as their condensed pyrazolo, pyridazino derivatives such as pyridazino[1,2-a]indazole-6,9,11-triones (4a-h) and 3,9-dioxo-3H,9H-pyrazolo[1,2-a]indazole (7) were synthesized. The antiinflammatory activity of some synthesized compounds was determined by carrageenan-induced rat paw edema technique using diclofenac as reference drug. The pharmacological data showed that most of the tested compounds exhibited a significant long lasting antiinflammatory activity, which in the case of compound 3b was superior to that of diclofenac.

Besides (-) pimara-8(14), 15-dien-19-oic acid [I] which had already been isolated as an active anti-inflammtory principle of Aralia continentalis, (-) kaur-16-en-19-oic acid [II] was separated as another active component of the plant, by tracing albumin stabilizing activity. $IC_{50}$ of [II] for the protein stabilizing activity was 0.026mg/3ml, when those of [I] and phenylbutazone were 0.032 and 0.32 mg/3ml, respectively. Being investigated employing carrageenin-induced edema test in rat hind paw, the anti-inflammatory activity of [II] administered s. c. was slightly lower than that of phenylbutazone, whereas the activity of [II] administered p. p. was three times greater than that of phenylbutazone. These results of [II] were contrary to those of [I] in the aspect of administration routes.

The bark of Ulmus davidiana var. japonica(Ulmaceae) has been described in traditional books to have diuretic and laxative actions, to ameliorate edematous disease, and to be used in insomnia and gastointestinal disorders. Thus this study was carried out to elucidate some of the pharmacological activities of the plant extracts. The results obtained in tills experiment indicated that its methanol extract elicited remarkable inhibition of HCI.ethanol induced gastric lesion, Shay ulceration and gastric secretion. However, it showed no anti-inflammatory action. The acute toxicity of the extract was low, that is, the minimum lethal dose was more than 2000 mg/kg by oral administration in mice. The systematic fractionation of the methanol extract by hexane, ether, ethylacetate and butanol resulted in potent prevention of gastric erosion in butanol and water fractions.
