This is a case report on the occurrence of caprine arthritis-encephalitis (CAE) disease among dairy goats in a local farm located in Yeongdong-gun, Chungbuk. Previously, it was reported that the farm experienced intermittent deaths numbering 15 of the 97 goats raised for 5 months. Most of the goats less than 6 months of age were suffering from ataxia and posterior paresis, body tremor and abnormal head posterior. Affected animals frequently had stunted growth and had a rough coat. Goats more than 6 months of age were affected with an insidious, chronic arthritis characterized by articular swelling ('big knee') of the carpal, hock, and stifle joints. Necropsy revealed severely swollen mesenteric lymph nodes, under- flow of 2-3ml synovial fluid in the articular space and fibrous proliferation of synovial membrane. Histopathological examination showed perivascular accumulations of mononuclear inflammatory cells in the white matter of the brain, proliferative synovitis characterized by villous hypertrophy, synovial cell hyperplasia and infiltration by mononuclear inflammatory cells. Pulmonary lesions consists of patchy interstitial pneumonia with hyperplasia of lymphoid tissues and an extensive mononuclear inflammatory cell infiltration into the alveolar septa. Confirmation by nested PCR involves amplification of a 296 bp (lst PCR) and 184 bp (2nd PCR) fragments corresponding to the gag region of the CAE virus. This is the first time CAE has been reported in a local farm in Korea and emphasizes the importances of developing preventive measures against CAE.

This study investigated the effects of mycelium and culture supernatant of Cordyceps ochraceostromat(Co) on air way hyper-responsiveness, pulmonary immune cell infiltration, and Th2 cytokine expression in animal models of atopy and asthma. After ConA(+/-) activation of mouse primary spleen cells, decreased IL-4 and IL-13 cytokine production were seen in the presence of Co mycelium extracts and culture supernatant. The asthma model involved mice sensitized to ovalbumin by i.p. injection treatment; Co mycelium extract was also injected. The atopy model was the dinitrofenylbenzene-treated mouse ear. Ear thicken ing induced by DNFB was decreased by Co mycelium extract, and the extract also inhibited lung cell infiltration in ovalbumin-induced asthmatic mice. The results thus indicated that the Co mycelial extract reduced the undesirable immune responses seen in asthma and atopy.

Churg-Strauss syndrome (CSS) is a necrotizing vasculitis with extra-, peri-vascular eosinophilic infiltration. Chronic symmetric polyarthritis with the presence of rheumatoid factor (RF) and anti-cyclic citrullinated peptide antibody are the mainstay of rheumatoid arthritis (RA) diagnosis. Mononeuritis multiplex is a peripheral neuropathy involving more than 2 separate nerve areas. A 62-year-old male patient was referred for left foot drop and polyarthritis of both hands and feet for 4 months. During evaluation, mononeuritis multiplex was detected on nerve conduction study and electromyography tests: vasculitis with neutrophil, eosinophil, and lymphocyte infiltration on peroneal nerve biopsy. A positive response to methacholin and bronchodilator was observed on the pulmonary function test. Radiologic tests showed peri-articular soft tissue swelling and osteopenia on both hand and foot. Marked peripheral eosinophilia, high RF, and positive perinuclear anti-neutrophil cytoplasmic antibody were detected on blood tests. Here, we report on a patient with overlap syndrome of CSS and RA with review of the relevant literature, from which a few references to overlap syndrome of CSS and RA were available.

연구배경 : 특발성 폐 섬유화확 병인론으로 폐포염과 폐에 침윤한 염증세포 및 폐 조직자체의 실질세포들이 성장인자를 포함한 다양한 cytokine을 분비하여 실질조직을 구성하는 세포에 손상을 야기함으로써 종국에는 섬유화를 초래하는 것으로 이해하고 있다. 그러나 이들에 대한 개괄적인 연구가 부족하고 매개체 각각에 대한 단편적인 논문들뿐이어서 본 연구에서는 BLM유도 폐 손상및 섬유화의 발생기전에 있어서 IL-1, IL-6, TNF-$\alpha$와 TGF-${\beta}_1$, PDGF, bFGF들의 역할을 규명하고자 하였다. 방 법 : Wistar백서를 정상대조군, BLM투여군, BLM과 비타민 E병합투여군으로 나누었고 BLM 투여후 제 1, 2, 3, 4, 5, 7, 14, 21, 28일에 각각 도살한 다음 기관지폐포 세척술을 시행하여 시기별 총 세포수, 세포 구성성분비율을 살펴보았고 TGF-${\beta}_1$, PDGF, bFGF, IL-1, IL-6, TNF-$\alpha$에 대한 면역조직화학 염색, TGF-${\beta}_1$ mRNA에 대한 동소보합결합검사를 시행, 각 매개체의 생성소, 발현분포 및 정도를 분석하였다. 결 과 : BLM 투여후 1~7 일에 중성구와 기관지상피세포에서 생성된 IL-1, IL-6는 폐손상부위로 원하는 것으로 생각되며 7일이내에 기관지상피세포에서의 IL-1, IL-6 의 양성발현은 기관지상피세포가 BLM 유도 폐 섬유화시 기도주변에서 일어나는 염증 및 면역반응을 항진 및 유지시키는 간접증거로 생각된다. TNF-$\alpha$는 BLM투여후 1~5일에는 기관지상피세포, 중성구가 주생성소로 폐손상부위로의 염증세포의 이동에 주요역할을 하는 것으로 생각되며 7~28일에는 대식세포가 주생성소로서 섬유화를 촉진시키는 것으로 생각된다. TGF-${\beta}_1$은 기관지 상피세포, 대식세포가 주생성소로서 섬유모세포가 표적세포로 생각되며 섬유모세포가 세포외 기질을 생성하도록 자극하고 대식세포에서 유리된 PDGF와 함께 섬유모세포의 증식을 자극한다. 대식세포 및 섬유모세포에서 유리된 bFGF는 TGF-${\beta}_1$과 함께 교원질과 같은 세포외기질의 생성을 자극하는 것으로 여겨진다. 비타민 E와 BLM 병합투여군의 경우 6가지 성장인자 및 cytokine의 발현세포는 같았으나 발현세포수는 극히 미미하였고 trichrome염색상 섬유화도 미약하였다. 결 론 : BLM으로 인한 혈관내피 및 폐포상피세포 손상이후 침윤한 중성구 및 기관지 상피세포가 IL-1, IL-6, TNF-$\alpha$를 분비하여 BLM투여 1~7 일에 많은 수의 중성구를 동원하도록 유도하며 이들이 유리하는 다양한 효소 및 산소유리기가 폐의 정상구조를 파괴하여 섬유화를 시작하게 하는 것으로 생각한다. 손상이 진행됨에 따라 BLM투여 7~28 일에 대식세포가 유리하는 TGF-${\beta}_1$, PDGF, bFGF, TNF-$\alpha$는 섬유모세포를 자극, 이들의 증식을 유도하고 또한 세포외기질의 생성증가를 유도하여 폐 섬유화를 진행시키는 것으로 사료되며 TNF-$\alpha$는 BLM투여후 전 기간에 걸쳐 다수의 세포에서 발현된 점으로 미루어 섬유화에 있어서 TGF-${\beta}_1$ 못지않은 중요한 역할을 하는 것으로 여겨진다. 또한 비타민 E가 BLM유도 폐 손상으로 인한 폐 섬유화의 정도를 감소시키는 것으로 생각한다.

연구배경: 결핵성 경부 림프절염은 우리나라에서 폐결핵만큼 빈도가 높은 질환이다. 이 질병에서 수지상돌기세포는 초기의 항원 제시역할을 하고 있다. 그러나 림프절염의 임상 양상과 관련된 항원제시세포의 역할은 아직 명확하게 밝혀져 있지 않은 상태이다. 경부 림프절의 수지상 돌기세포의 침윤과 임상양상과의 연관성을 알아보기 위해 본 연구를 시행하였다. 방 법: 환자들의 입원기록 및 방사선사진을 바탕으로 후향적으로 고찰하였다. 72례의 조직표본을 대상으로 항산균도말염색을 다시 시행하였고, 수지상돌기세포의 단클론항체로 S-100b를 이용하여 면역조직 화학염색을 시행한 후, 각각 결핵성 육아종안의 수지상돌기세포의 수를 세어 비교분석하였다. 결 과: 결핵성 경부 림프절염이 있는 환자들의 30%가 폐결핵의 과거력이 있거나 현재 폐결핵을 앓고 있는 상태이었고 21%의 환자에서 항산균도말염색양성을 보였다. 이들 한 육아종안에 침윤된 수지상돌기세포의 수는 평균 $113.0{\pm}7.0$개이었다. 육아종내 수지상돌기세포의 침윤수가 증가됨에 따라 발열과 기침의 빈도는 감소하였고 항산균도말염색상에서 결핵균의 수가 더 감소하는 결과를 보였으며, 다중로짓회귀분석을 보면, 수지상돌기세포의 침윤은 특징적으로 발열에 기여하여하는 것으로 나타났다. 결 론: 수지상돌기세포가 결핵성 경부 림프절염에서 발열과 기침 등의 전신증상을 줄이고, 결핵균의 침윤정도를 감소시키는 것으로 확인되었고, 이는 수지상돌기세포가 Mycobacterium tuberculosis의 감염을 조절하고 이와 함께 면역반응도 조절하여, 결핵성 경부 림프절염에서의 임상양상을 결정하는 것으로 생각된다.

We have performed 14 single lung transplantation in mongrel dogs transplanting the left lung exclusively from December 1989 to January 1991, in the department of thoracic surgery of Seoul National University Hospital. In the donor dogs, the main pulmonary artery was divided proximal to its bifurcation, and the left atrium was incised freeing the left veins with a generous atrial cuff. We used cold saline in the first 7 transplantation[group I ] and a Euro Collins solution in the remaining 7 transplantations[group II ] as a lung preservatives. The bronchus was divided at two cartilage rings proximal to the upper lobe bronchus take off. In the recipient procedure, we used a Fogarty catheter as a bronchus block. Left atrial anastomosis was performed first using 5 - 0 prolene and the pulmonary artery was anastomosed using 6 - 0 prolene. The bronchus was anastomosed next with 4 - 0 Vicryl interruptly and covered with a greater omentum which had been prepared previously. In group I the three dogs died at eleven hours, 5 days, and 14 days, postoperatively and the remaining four doings were killed at 5 days, 5 days, 6 days, and 12 days, respectively. In group II the two dogs died during the operation, one dog died at 6 hours, two dogs died at 6 days postoperatively. Two dogs were killed at 5 days, and 7 days. No significant difference was noted between the two groups in survival time, lung infiltration of transplanted lungs, and perfusion defects in perfusion lung scans. Of the 8 dogs which died naturally, the causes of death were as follows: 2 cases of sepsis, 2 cases of ventricular fibrillations, 2 cases of malnutrition, and 2 cases of respiratory failures.

Eosinophilic lung diseases are heterogeneous disorders characterized by varying degrees of pulmonary parenchyma or blood eosinophilia. Causes of eosinophilic lung diseases range from drug ingestion to parasitic or fungal infection as well as idiopathic. The exact pathogenesis of eosinophilic lung disease remains unknown. Urushiol chicken can frequently cause allergic reactions. Contact dermatitis (both local and systemic) represents the most-common side effect of urushiol chicken ingestion. However, there has been no previous report of lung involvement following urushiol chicken ingestion until now. A 66-year-old male was admitted to our hospital with exertional dyspnea. Serial chest X-ray revealed multiple migrating infiltrations in both lung fields, with eosinophilic infiltration revealed by lung biopsy. The patient had ingested urushiol chicken on two occasions within the 2 weeks immediately prior to disease onset. His symptoms and migrating lung lesions were resolved following administration of oral corticosteroids.

In order to evaluate the antitumor activity and immunomodulatory effects of Seoleosojong-tang(SST), studies were done. We measured the cytotoxic activity for various kinds of cancer cells, inhibitory effect on activity of DNA topoisomerase I, cell adhesion to complex extracellular matrix, survival time in ICR bearing S-180, pulmonary colonization and histological changes of lung in C57BL/6 injected i.v. with B16-F10, CAM assay, expression of CD4/sup +/, CD8/sup +/, B220/sup +/, cytokine gene in spleen cell. The results were obtained as follows: 1. In cytotoxicity against A549, HT1080, 816-F10, NCL-H661 was showed cytotoxicity as compared with control. 2. The inhibitory effect on adhesion of A549, 816-F10 to complex extracellular matrix was over 40% at 100 ㎍/㎖ of SST. 3. In DNA topoisomerase I assay, SST has inhibitory effect. 4. The T/C% was 120.8 in SST treated group in S-180 bearing ICR mice. 5. In pulmonary colonization assay, a number of colonies were decreased significantly and histological changes were showed that infiltration area of cancer cells were inhibited effectively in SST treated group. 6. In CAM Assay, SST has antiangiogenic effect. 7. On the expression of positive cell to CD4/sup +/, CD8/sup +/ and 8220/sup +/ in spleen cells, CD4/sup +/ cells were increased significantly in SST treated group. 8. Effect of SST on IL-1β gene expression in splenic cell was significantly increased as function of whole concentration. 9. The gene expression of IL-4, IL-6, IL-10, IL-12, IFN-γ, TNF-α were increased in SST treated group. From above results SST could be usefully applied for antitumor activity and immunomodulatory effects, but further research of SST should be required.
