  • Ulmi Cortex has been used for edema, articular rhematism and acne, etc in oriental medicine. Here, experimentally the MeOH extract showed significant anti-inflammatory action, inhibitory effect of leukocyte emigration in rats and the growth inhibition of Sta. aureus, Strep. faecalis, Psu. aeruginosa and Bacillus sp. The ether layer showed analgesic effect stronger than that of MeOH extract and BuOH layer showed antimicrobial activity stronger than that of the other layer.

  • In an attempt to elucidate the anti-inflammatory action of ginseng total saponin, protopanaxadiol and protopanaxatriol, the anti-inflammatory activity of three compounds was investigated under various acute and chronic inflammatory models. The blood vessel permeability was slightly inhibited by total saponin and protopanaxatriol treatments. Granuloma formation induced by 2% carrageenan was inhibited by total saponin and protopanaxatriol. The cotton-pellet granuloma formation was significantly inhibited by intraperitoneal injection of total saponin. Total saponin and protopanaxadiol inhibited leukocyte emigration and protein exudation in CMC-induced pouch but protopanaxauiol increased leukocyte emigration. The swelling of rat hind paw induced by 1% carrageenan was significantly inhibited by total saponin, protopanaxadiol and protopanaxatriol both single and 2 weeks treatments. Total saponin, protopanaxadiol and protopanaxatriol decreased the anti-inflammatory activity in adrenalectomized rat. Our results suggest that total saponin, protopanaxadiol and protopanaxatriol have potent anti-inflammatory activity, this may be mediated in part through stimulation of adrenal glands.

  • Daidzein and its methyl derivatives were synthesized and their anti-inflammatory activities were examined. Daidzein suppressed the carrageenin-induced edema, but its methyl derivatives showed decrease or abolition of the anti-inflammatory effect. Daidzein did not significantly suppress the complete Freund's adjuvant-induced arthritis, and the mixed phlogistics (histamine+serotonin)-induced edema. Daidzein inhibited the leukocyte emigration and protein exudation when it was administered into the CMC pouch at low doses (5,25mg/pouch). Daidzein significantly suppressed the cotton-pellet granuloma formation.

  • Chunggisan has been widely used in treatment of urticaria which is based on. Oriental Medical literatures. These studies were attempted experimental effects of chunggisan on the analgesia, sedation, antipyretic, anti-inflammatory and isolated illeum of the experimental animals. The result of the studies were as follows: 1. The inhibitory effect was recognized on the Analgesic study by the Acetic acid Method in mice. 2. The spontaneous momentum of mice was restricted and the duration of Hypnosis induced by pentobarbital-sodium in mice was prolonged. 3. Anti-inflammatory effect was recognized significantly on the rat hind paws edema induced by dextran. 4. The inhibitory effect of leukocyte emigration was recognized by the CMC airpouch method of rats. 5. The inhibitory effect was noted on capillary permeability induced by histamin in mice. 6. Spontaneous mobilities in isolated ileum of mice were significantly suppressed, and contraction by acetylcholine, barium chloride and histamine were inhibited. According to the above results, it is expected that chunggisan can be widely used in treatment of urticaria.

  • This study was conducted to examine the development of a new anti-inflammatory substance with potent anti-inflammatory activities that was derived from the Platycodi Radix butanol fraction. To accomplish this, the chemical structures and anti-inflammatory activities of the components were elucidated. Upon column chromatography of the tertiary subfraction, fractions 8-4-1 and 8-4-2 were identified as platycodin D and D3, respectively, following recrystallization, based on melting point (MP), infrared (IR), and positive fast atom bombardment (FAB)-mass and nuclear magnetic resonance (NMR) spectral data. Platycodin D and D3 exhibited strong anti-inflammatory activities in rats when administerd at oral doses of 12 mg/kg and 36 mg/kg, p.o., respectively. Platycodin D and D3 induced inhibitory effects on capillary vascular permeability in rats at oral doses of 16 mg/kg and 24 mg/kg, p.o., respectively, and potent inhibition of leukocyte emigration in a carboxymethyl cellulose (CMC)-pouch when administered at doses of 3 mg/rat and 7 mg/rat, s.c., respectively. These results verified the high antiinflammatory potency of the platycodin D and D3 components in Platycodi Radix.
