There are many important factors in periodontal inflammation. $IL-1{\beta}$, $PGE_2$ and collagenase are predorminantly key factors. These inflammatory mediators induce gingival tissue and alveolar bone destruction. For the prevention and treatment of periodontal disease, it is necessary to inhibit $IL-1{\beta}$, $PGE_2$ production and collagenase activity. Ursodeoxycholic acid(UDCA) has immunomodulatory properties, and there is evidence that some natural extracts show antiinflammatory activity to some degree. The purpose of this study was to assess the inhibitory effect of UDCA and its mixture with natural extracts on $IL-1{\beta}$, $PGE_2$ production and collagenase activity. Accordingly we assessed the effect of UDCA and its mixture combined with some natural extracts on inhibition of $IL-1{\beta}$, $PGE_2$ production and collagenase activity. For the $IL-l{\beta}$ inhibition study, cultured cells were exposed to $25{\mu}g/ml$ LPS. $IL-1{\beta}$ activity was measured by $IL-1{\beta}$ enzyme immunoassay system. Human gingival fibroblasts were prepared and cells (l05/well) were seeded into culture plates. $rhIL-1{\beta}$ was added to induce $PGE_2$. The amount of $PGE_2$ in sample media was measured using enzyme immunoassay system. Crude collagenase was prepared from Porphyromonas gingivalis and collagenolytic activity was determined using a Collageno kit CLN-100. The test inhibitor was added to the assay mixture consisting of 0.1ml of 50mM Tris buffer(pH 7.5) and 0.2ml of substrate solution. UDCA and UDCA combined with natural extracts generally inhibited $IL-1{\beta}$ production. groups above 0.01% UDCA strongly inhibited $IL-l{\beta}$ synthesis. Both groups inhibited $IL-1{\beta}-induced$ synthesis of $PGE_2$. In low concentration, the degree of inhibition was as same as prednisolone. In high concentration, each group was superior to prednisolone. UDCA group and UDCA mixture group exerted a moderate inhibition of collagenolytic enzyme. The present study suggested that UDCA and its mixture with natural extracts could be further investigated as antiinflammatory drug for periodontal disease.

This study was aimed; firstly to observe various clinical symptomatology with reiation to the number of Ancylostoma duodenale larvae orally given to the human beings, secondly to evaluate the effects of some drugs like steroid hormones, antihistaminic3 and antitussives, and, thirdly to study the influences of some iron compounds in prevention and treatment of anemia of such origin. Ten healthy volunteers free from the previous history of hookworm infection were divided into 4 groups, to whom various numbers of actively moving filariform Ancylostoma duodenale larvae were orally given; 500 to 4 cases, 250 to 3 cases and 100 to 3 cases. Following were the results: 1. Clinical symptomatology 1. The most frequently encountered symptoms and signs were general malaise, cough and hoar seness. The tracheal itching and pain low back pain, arthralgia, sputum and salivation, acid belching, loss of appetite, abdominal pain and vomiting were also noted. 2. If the larger number of the larvae was given, the clinical symtomatology was more severe. 3. Prednisolone medication caused some improvement of such symptomatology, while the antihistaminics and antitussives like codeine or ephedrine were ineffective. 4. In volunteers whose nutritional conditions were rather poor appeared to show more severe symptomatology. 2. Effects of iron compounds 1. The oral administration of ferrous fumarate induced a slight increase of serum iron levels in the initial stage of the infection, then a decrease from $15{\sim}20$ days later and a recovery after 2 months. 2. The intravenous administration of saccharated ferric oxide induced a steady upkeep of the serum iron levels. 3. The hemoglobin contents also showed the upkeeps after either the oral or intravenous administration of the iron compounds. 4. The iron compounds, therefore, are considered to have the preventive as well as the therapeutic effects on hookworm anemia, which may strongly suggest that hookworm anemia is essentially the iron deficiency type. 3. Hematological changes 1. The severity of hookworm anemia generally correlated with the number of larvae given. 2. The moderate leucocytosis was observed in all cases regardless of the number of larvae given, which reached to a peak in $25{\sim}35$ days. 3. Eosinophilia was observed in all cases, but was more severe in cases given larger number of larvae, which was slightly less evident after the medication of prednisolone. 4. Red cell survival time The red cell survival time determined by $^{51}Cr$ was generally in the normal ranges except for the severe anemia patients.

목 적 : ACE inhibitor는 주로 항고혈압제제로 사용되고 있으나 정상 혈압을 가진 신질환 환자에서 단독으로 쓰일 경우 단백뇨를 감소시키고 신기능을 보호하는 효과가 있음이 보고되었다. 그러나 소아 신증후군에서 스테로이드와 병합 투여할 경우 단백뇨 소실에 상승작용이 있는지에 대해서는 별로 알려진 바가 없다. 이에 저자들은 신증후군 환아에서 스테로이드와 ACE inhibitor인 Inhibace의 병합투여가 단백뇨 소실에 미치는 영향을 관찰하기 위하여 본 연구를 시행하였다. 방 법 : 원발성 신증후군으로 내원한 환아를 대상으로 치료방법에 따라 Prednisolone 2mg/kg/day를 단독으로 투여한 환아(대조군)와 Prednisolone 및 Inhibace 2.5mg/day를 같이 투여한 환아(Inhibace군)로 구분하였으며 이 중 치료에 반응을 보인 45명(대조군 29명, Inhibace군 16명)을 대상으로 치료결과를 비교하였다. 결 과 : 두 군간의 평균연령 및 남녀비는 유의한 차이가 없었다. 발병시 24시간 요중 단백량은 대조군 $699.6{\pm}1396.6 mg/m^2/hr$, Inhibace군 $624.9{\pm}275.1\;mg/m^2/hr$로 유의한 차이는 없었다. 스테로이드 투여 후 단백뇨 소실까지의 기간은 Inhibace군에서 $10.9{\pm}2.0$일로 대조군의 $13.6{\pm}4.0$일보다 유의하게 짧았고 (P<0.05) 성별 및 연령에 따른 차이는 없었다. 치료 전후의 혈청 콜레스테롤 농도는 대조군과 Inhibace군 간에 유의한 차이가 없었으며 Inhibace군에서 치료 전후에 크레아티닌 청소율의 유의한 변화는 없었다. 혈압의 변화는 두 군간에 유의한 차이는 없었으며 Inhibace 군에서 저혈압의 소견은 보이지 않았다. 결 론 : 소아 신증후군에서 스테로이드와 ACE inhibitor의 병합투여는 스테로이드 단독 투여에 비해 완해에 이르는 기간을 단축시키는 효과가 있는 것으로 사료되며 앞으로 장기간의 ACE inhibitor의 투여가 재발율 및 관해 유지에 미치는 영향에 대한 연구가 더 필요할 것으로 생각된다.

목 적: DBA는 적혈구 저형성증, 선천성 기형, 그리고 암으로 진행할 수 있는 가능성을 지닌 드문 유전성 질환이다. Corticosteroid와 수혈이 주된 치료이다. 본 연구에서는 16년 동안 경험했던 6명의 환아의 임상양상, 혈액학적 특징, 치료 및 경과에 대해 기술하고자 한다. 방 법: 1992년부터 2008년까지 전남대학교병원에서 DBA로 진단 받은 6명의 환아의 의무기록을 후향적으로 고찰하였다. 결 과: 6명 중 3명의 환자는 남아였고, 진단 당시 나이는 2개월에서 18개월(중앙값, 5.5개월)사이였다. 4명의 환자에서 선천성 심장기형이 동반되었고, 그 외 기형으로 다지증이 2명, 사시가 1명에서 발견되었다. 수혈은 2회에서 8회까지 시행되었으며, 진단 후 모든 환자는 스테로이드로 치료를 시작하였다. 치료 시작 후 혈색소 수치가 9 g/dL 이상으로 반응을 보인 시기의 중앙값 12.5일(범위, 7-22일)이었다. 치료 시작 후 3명의 환자는 스테로이드 투약을 점감한 후 투약을 중지하였고, 3명의 환자에서 최소량의 prednisolone (${\leq}5mg$/일)로 투약을 지속하고 있다. 환자들의 추적 관찰기간의 중앙값은 14년이며 추적 관찰 중 저신장을 제외하고 스테로이드와 관련된 부작용이나 암의 발생은 발견되지 않았다. 결 론: DBA 환자의 대부분 스테로이드 치료에 반응을 보이며 저용량으로 혈색소 수치를 유지할 수 있다. 하지만 스테로이드의 장기복용으로 인한 부작용 및 심장기능, 암의 발병 등에 대한 보다 적극적인 추적관찰이 요구되고, 국내 DBA 환자들에 대한 대단위 연구도 병행되어야 할 것으로 생각된다.

Purpose: We performed this study retrospectively to evaluate local control, survival, prognostic factors, and failure patterns in patients with non-Hodgkin's lymphoma of Waldeyer's ring. Materials and Methods: From April 1984 to November 1996,41 patients with non-Hodgkin's lymphoma of Waldeyer's ring were treated with combined chemotherapy and radiation therapy. Age was ranged from 19 to 73 years old with a median age of 55 years, and there were 26 male and 15 female patients. Primary site was tonsil in 26 and base of the tongue in 7 and nasopharynx in 8, and stage distribution showed stage I in 12 and stage II in 29 patients. Pathologic classification was done according to Working Formulation. There were 1 with follicular mixed small cleaved and large cell, 8 with diffuse small cleaved cell, 7 with diffuse mixed small and large cell, and 25 cases with diffuse large cell. All patients were treated with combination of chemotherapy and radiation therapy. Chemotherapy regimen consisted of either CHOP-Bleo(cyclophosphamide, adriamycin, vincristine, prednisolone, bleomycin) or COP-BLAM III(cyclophosphamide, vincristine, prednisolone, bleomycin, adriamycin, procarbazine). Radiation dose ranged from 3600cGy to 6620cGy with a median dose of 5040cGy. Follow-up time was ranged from 15 months to 159 months(median 55 months). Results: The complete response was achieved in 98%(40/41) and partial response in 2%(1/41). The complete response rate were the followings: 66.7% for stage I and 51.7% for stage II after chemotherapy, 100% for stage I and 96.6% for stage II after overall treatment respectively. The overall survival rate and disease-tree survival rates at 5 years were 82.6% and 79.5%, respectively. Prognostic factors for overall survival were age(p=0.007), stage(p=0.03), nodal status(p=0.006) and radiation dose(p=0.003). The factors associated with disease-tree survival were stage(p=0.04), nodal status(p=0.004) and radiation dose(p=0.009). The failure patterns were analized in evaluable 35 patients with complete response. Locoregional failure was noted in 2 patients and distant metastasis in 5 patients. Conclusion: Our results suggest that combined modality therapy is the appropriate treatment for stage I-II intermediate grade non-hodgkin's lymphoma of the Waldeyer's ring. However, our material is small and the analysis is retrospective. Randomized prospective studies for combined therapy, radiation therapy alone and chemotherapy alone are needed.

Inflammatory bowel disease (IBD) is a multifactorial disorder with unknown etiology and pathogenesis. DA-6034,$ 7-carboxymethyloxy-3^{l}, 4^{l},$ 5-trimethoxy flavone, is a synthetic flavonoid known to possess anti-inflammatory activity. This study was performed to evaluate the oral therapeutic effect of DA-6034 in three experimental animal models of IBD : two chemical-induced IBD models of rats and the human leukocyte antigen (HLA)-B27 transgenic rat model known to develop spontaneous colitis without the use of exogenous agents. Acute chemical colitis was induced by intracolonic instillation of 1.2 ml of 4% acetic acid solution. Prednisolone (1 mg/kg), sulfasalazine (100 mg/kg) and DA-6034 (0.3~3 mg/kg) were orally administered twice daily for 6 days in these rats. In addition, chronic chemical colitis was induced by intracolonic administration of trinitrobenzene sulfonic acid (TNBS) 30 mg in 50% ethanol and agents were orally administered for 6 or 20 days. In chemical-induced IBD models, all of these agents reduced the severity of colitis and specially, DA-6034 (3 mg/kg) showed more potent effect than other drugs in macroscopic lesion score. In HLA-B27 transgenic rats, DA-6034 (3 mg/kg) and prednisolone (0.5 gm/kg) were treated orally twice daily for 6 weeks. The HLA-B27 transgenic rats showed only mild colitis, compared with the chemical-induced colitis models. DA-6034 ameliorated the loose stool and decreased microscopic damage, which is the important indicator of this model. In conclusion, oral therapy of DA-6034 attenuated the macroscopic and histologic damages of the colon in all three experimental models of IBD, which suggest that DA-6034 could be a promising drug in the treatment of IBD.

Objectives : The effects of water extract of deer antler herbal-acupunture solution(DHS), prepared from the pilose antler of Cervus korea TEMMINCK var. mantchuricus Swinhoe (Nokyong), a traditional immunosuppressive and immune-activating Korean herbal- acupuncture, on collagen-induced arthritis(CIA:RA model) in mice was studied. Destruction of cartilage and bone are hallmarks of human rheumatoid arthritis, and controlling these erosive processes is the most challenging objective in the treatment of RA. Methods : We investigated the tissue protective effects of deer antler treatment using established murine collagen-induced arthritis(CIA) as a model. Potential synergy of low dosages of anti-inflammatory glucocorticosteroids and deer antler was also evaluated. Results : Treatment of established murine CIA with deer antler herbal-acupunture solution(DHS) $(10-50{\mu}g/day)$ suppressed disease activity and protected against cartilage and bone destruction. Although $10-50{\mu}g/day$ DHS had only a moderate effect on the inflammatory component of the disease activity, it strongly reduced cartilage pathology, as determined by histological examination. Serum cartilage oligomeric matrix protein(COMP) levels were significantly reduced, confirming decreased cartilage involvement. Histological analysis showed that bone destruction was prevented. DHS administration increased serum IL-1Ra levels and reduced anticollagen type II antibody levels. Treatment with low-dose $DHS(1{\mu}g/day)$ was ineffective in suppressing disease score, serum COMP or joint destruction. Synergistic suppression of both arthritis oseverity and COMP levels was noted when low-dose DHS was combined with prednisolone(0.05mg/kg/day), however, which in itself was not effective. Conclusion : DHS was shown to have the inhibiting effects against $IL-1{\alpha}-$ and $IL-1{\beta}-stimulated$ bone resorption. These results indicated that the DAS is not only highly stable and applicable to clinical uses in bone resorption, but also it will be served as a potent anti-inflammatory and anti-arthritic agents for treatment of human RA.
