  • Present study was aimed to examine whether indomethacin affected the production of NO in the rat paw exudate by carrageenin. Paw edema and nitrite/nitrate levels in the paw exudate were maximal after 4 h and remained elevated up to 10 h, whereas indomethacin (10 mg/kg, po) significantly inhibited the carrageenin-induced paw edema and levels of nitrate in the paw exudate. However, paw edema and nitrite/nitrite levels were increased thereafter for 10 h. Indomethacin also enhanced the expression of iNOS mRNA and protein 4 h after carrageenin infection. Indomethacin inhibited the level of $PGE_2$ in the paw exudate in a time-dependent manner. These results suggest the possibility that indomethacin may potentiate expression of iNOS and subsequently increase nitrite/nitrate level in the late phase of carrageenin-induced rat paw inflammation possibly by suppressing cycloxygenase activity.

  • Objectives This study was to investigate the effects of Yuhyangjeongtong-san on the carrageenin-induced acute inflammation and adjuvant-induced arthritis in rats. Methods Acute inflammation was induced by injection of 2% carrageenin 0.15 ml into right hind foot of rats. Control group was carrageenin injected and taken distilled water, treated group was carrageenin injected and taken Yuhyangjeongtong-san by orally once. 2 hours after injection, plantar temperature and paw volume were measured. 3 hours after, counts of white blood cell (WBC) were performed. Arthritis was induced by injection of complete freund's adjuvant (CFA) into base of tail. Control group was CFA injected and taken distilled water, treated group was CFA injected and taken Yuhyangjeongtong-san by orally for 10 days. 0,5,10 day, body weight, thickness of ankle joint and paw edema were measured. 10 day, counts of WBC, $interleukin-1{\beta}$ ($IL-1{\beta}$) and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) level were analysed. Histochemical study of NADPH-d and immunohistochemical study of c-fos were performed. Results In the carrageenin-induced acute inflammation, neutrophils of treated group were significantly decreased compared with control group. In the adjuvant-induced arthritis, paw edema, total counts of WBC and TNF-${\alpha}$ level in paw exudates were significantly decreased compared with control group, and the number of c-fos positive neurons of treated group was significantly decreased compared with control group. Conclusions On the basis of these results, we concluded that Yuhyangjeongtong-san have anti-arthritic and anti-inflammatory effects.

  • The present study was undertaken to investigate modification in electrophysiological characteristics of cat dorsal horn cells resulting from carrageenin-induced inflammation. The followings were studied; 1) the time-course of changes in responses of the WDR (wide dynamic range) cell 1-3h after subcutaneous injection of carrageenin in its receptive field; 2) the responses of the same dorsal hern cells before and after induction of inflammation; 3) the effect of inflammation on the responsiveness of dorsal horn neurons to algogens (bradykinin & potassium); and 4) the effect of inflammation on the activity of WDR cell following administration of indomethacin and clonidine. Though responses of WDR neuron were increased dramatically during first 1h, the maximal enhancement was observed 3h after induction of inflammation especially by repetitive light tactile stimulus. Following carrageenin injection the majority of WDR neurons (10/15 units) showed enhanced responses to all the mechanical stimuli while in 3 cases responsiveness were intensified during activation by one tactile stimulus (brush or pressure). One cell was unaffected by inflammation and in another case the response was enhanced only to noxious stimulus. Five of 9 cells that could initially be driven by noxious stimulus were activated more strongly by same stimulus and even by tactile stimulus (pressure) following inflammation. In 2 cases neurons were sensitized only to noxious stimulus whereas in another 2 cells that did not show enhanced responses to noxious stimulus responses to light tactile stimulus (pressure) appeared after inflammation. Of 16 LT cells tested 6 responded to squeeze while 4 showed the characteristics of WDR cell following inflammation. No modification in responsiveness was recognized in 3 cells whereas response to only brush was enhanced in another 3 neurons. Following carrageenin injection responses of LT cell to bradykinin or $K^{+}$ were not altered whereas those of WOR neurons to bradykinin or $K^{+}$ were suppressed in 22.2% and 33.3% of cases, respectively. In two of 8 activity of HT cells were inhibited by bradykinin while in five of 8 responsiveness to $K^{+}$ were rather enhanced by inflammation. In the rest inflammation was ineffective. In inflammation-induced animal the receptive field of LT cell was not changed whereas those of WDR cell and HT cell were tremendously expanded. The enhanced responses of WDR neurons to mechanical stimuli resulted from inflammation were suppressed by intravenously injected indomethacin and clonidine suggesting that postaglandin is involved in inflammation-induced sensitization of these cells. The involvement of peripheral and central mechanisms in the modification in responsiveness of dorsal horn cells in the carrageenin-induced inflammation was discussed.

  • Steroidal alkaloid인 cyclobuxine D의 carrageenin으로 유발한 늑막염과 croton oil로 유발한 육아종양에 대한 영향을 관찰하고 그 작용을 aspirin, dexamethasone과 hydrocortisone의 작용과 비교하였다. Carrageenin으로 유발한 늑막염에서 혈장 삼출정도는 pontamine sky blue을 정맥으로 투여하여 20분 동안 늑막염 삼출물로 삼출되어 나오는 양으로 측정하였다. Cyclobuxine D는 용량적으로 삼출물의 양과 20분 동안 삼출되는 pontamine sky blue의 양을 감소시켰다. Cyclooxygenase 억제제인 aspirin과 phospholipase $A_2$를 억제하여 결과적으로 cyclooxygenase와 lipoxygenase의 생성물을 차단하는 dexamethasone은 현저하게 carrageenin으로 나타나는 염증현상을 억제하였다. Cyclobuxine D는 croton oil로 유발한 육아종양에서 종양 부위에 직접 투여하거나 근육내로 투여해도 pouch내 염증물 양과 pouch wall의 무게를 현저하게 억제하였다. Dexamethasone과 hydrocortisone은 육아종양의 형성을 현저히 억제하였으며 , dexamethasone은 근육내로 투여 하였을 때 육아종양 형성을 완전히 억제하였다. 이상의 결과에서 나타난 cyclobuxine D의 항염증 작용은 prostaglandins의 생성억제 또는 polymorphonuclear cell (PMN)의 유주 억제와 밀접한 관련이 있을 것으로 사려된다.

  • To investigate the morphology of the synovial lining cells, synovitis was induced by carrageenin injection into the rat knee joint cavities. Synovial membranes were excised at 1, 3, 5, 7 and 14 days, and histologic, electron microscopic, histochemical (periodic acid Schiff: PAS, toluidine blue), and enzyme histochemical (acid phosphatase: ACP, nonspecific esterase: NSE and endogenous peroxidase) studies were performed. The results are as follows: Carrageenin induced synovial membrane hypertrophy with synovial cell proliferation and granuloma formation. The proliferated synovial lining cells and macrophages in the granulomatous lesion had round to oval nuclei and large, plump cytoplasm with many phagocytotic materials and vacuoles. Electron microscopically, these cells had small number of granular endoplasmic reticulum and many lysosomes, phagosomes and vaculoes. Mitotic figures were observed at early stage of experiment. PAS and toluidine blue stains showed strongly positive reaction in the cytoplasm of the proliferated lining cells and macrophages in granulomatous lesion. ACP and NSE activities were strong positive in the cytoplasm of the proliferated synovial lining cells and macrophages in the granulomatous lesion. But endogenous peroxidase stains were negative in all prolifeative lining cells and macrophages in granulomatous lesion. Conclusively, carrageenin-induced synovitis showed proliferation of synovial lining cells and granuloma formation in deep layer. The macrophages, which consisted of the lesions and have active phagocytic function, were speculated to proliferate by mitosis of superficial synovial A cells and histiocytes in the deep layer of the synovial membrane.

  • The possibility as an anti-inflammatory drug of Prunus davidiana which have been used in Korean folk medicine for treatment of neuritis and rheumatism was investigated on carrageenin-induced paw edema in rats. The MeOH extract exhibited potent inhibitory effect on carrageenin-edema rats when topically applicated. On the other hand, it did not show any effect when orally tested. It also had no influences on isolated ileum of guinea pig and anti-platelet aggregating activities. Thus, it appears from the present findings that the MeOH extract of P. davidiana may be utilizable only for the external treatment of inflammed sites. This study was also conducted to further isolation of flavonoids from the EtOAc soluble fraction and characterized as persiconin and isosakuranin by spectrometric analysis.

  • 느릅나무(Ulmus davidiana var. Japonica)는 한국이나 중국 등에서 오래 전부터 전통의 민간요법으로 열매, 뿌리를 염증 및 종창 환부에 도포하여 항염제로 이용하거나, 중탕 추출하여 소화기 궤양 및 종양 등에 사용하여 왔다. 또한 한방에서는 유근피가 다량의 점액과 탄닌을 함유하고 있어 완화제, 치습, 이뇨, 소종독(消腫毒) 등에 이용하여 오고 있다. 본 연구에서는 유근피로부터 다당류를 분리 정제한 후 화장료 조성물로써의 사용 가능성을 확인하고자, 유근피 추출 다당류의 보습효과 및 소염효과 등을 조사하였다. 유근피에서 침출법으로 다당류를 분리정제한 후 가수 분해하고, 가수분해 생성물을 HPLC로 분석하여 주구성 당분이 람노오스, 갈락토오스, 글루코오스 등임을 확인하였고 GPC로 측정한 평균분자량은 20,000이었다. Corneometer CM820 등을 이용한 보습효능 실험 결과 히알루론 산과 견줄만한 효능을 확인할 수 있었으며, carrageenin에 의해 유도된 부종억제 효능 실험에서는 ketoprofen에 버금가는 좋은 효능을 나타내었다. 결론적으로 유근피 추출 다당류가 좋은 화장료 조성물로써 유용하게 사용될 수 있음을 확인하였다.

  • Objectives : To provide the information of preservation method for herbal decoction, we evaluated the anti-inflammatory effects according to preservation temperature and period of Pyungwi-san (PWS, Ping wei-san) decoction. Methods : The anti-inflammatory activity of PWS was investigated by carrageenin-induced paw edema in SD rats. At 0 month, PWS extract was administrated 100, 300 and 1000 mg/kg/day orally for seven days prior to induction of edema. Edema was induced by subcutaneous injection of 1% carrageenin into the right hind paw. The paw volume was measured at 4 hr following carrageenin-induced paw edema in rats. At 6 and 12 months, PWS extracts according to preservation temperatures (room temperature, $4^{\circ}C$ and $-20^{\circ}C$) were administrated in rats and then carrageenin-induced paw edema volume was measured. Results : PWS showed inhibitory effect on carrageenin-induced paw edema in rats and the optimal dose was 1000 mg/kg/day at 0 month of storage. At 6 month of storage, PWS storaged at $4^{\circ}C$ and $-20^{\circ}C$ were inhibited paw edema but that storaged at room temperature was not reduced paw edema in rats. Conclusions : These results suggest that PWS decoction pouch has anti-inflammatory activities at both $4^{\circ}C$ and $-20^{\circ}C$ during 6 month storage.
