  • 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.

  • Five dogs at the age of 2-13 years, with variant respiratory signs like as dry cough, dyspnea, exercise intorelance and lameness were presented. On thoracic radiographs, all dogs had abnormalities such as soft tissue density, round mass image, increased pulmonary infiltration and pleural effusion. All dogs were diagnosed as adenocarcinoma on cytopathologic examinations by fine needle aspiration with ultrasound guidance. Computed tomography was performed in three cases to evaluate clinical stage. Primary papillary adenocarcinoma was confirmed after necropsy in one case.

  • Eosinophilic pleural effusions (EPE) are defined as those effusions that contain at least 10% eosinophils, and EPE can be associated with peripheral blood eosinophilia in a variety of systemic diseases. There have been a few cases that have addressed the association of peripheral blood eosinophilia and posttraumatic EPE, and this condition can be misdiagnosed as being the result of other causes due to the delayed presentation. We report here on a case of 47-year-old male who presented with eosinophilic pleural effusion associated with peripheral blood eosinophilia at 2 months after minor chest trauma. We excluded the other possible causes such as consumption of drugs, parasite infection, malignancy, diseases of pulmonary eosinophilic infiltration, autoimmune diseases and pulmonary thromboembolism. We observed his clinical course without specific treatment. Three months later, the pleural effusion completely disappeared and the number of peripheral eosinophils returned to normal.

  • The Pulmonary Infiltration and Eosinophilia Syndrome (PIE Syndrome) includes a wide spectrum of clinical disorders with pulmonary infiltrates and peripheral eosiophilia. It is poorly understood and ill-defined group of disorders. Often its etiology is poorly delineated. There may exist an eosinophilic type of alveolitis in the category of PIE syndrome. It shows characteristic clinical picture, peripheral eosinophilia and especially dramatic improvement following therapy with corticosteroids. We report a case of the syndrome in 43-year-old man with brief review of contemporary literature. In this case, the diagnosis was confirmed by open lung biopy which showed characteristic eosinophilic alveolitis accompanied by periphiral eosinophilia. Corticosteroid was administered with rapid clinical improvement in this case.

  • HemoHIM, herbal preparation has designed for immune system recovery. We investigated the anti-inflammatory effect of HemoHIM on cigarette smoke (CS) and lipopolysaccharide (LPS) induced chronic obstructive pulmonary disease (COPD) mouse model. To induce COPD, C57BL/6 mice were exposed to CS for 1 h per day (eight cigarettes per day) for 4 weeks and intranasally received LPS on day 26. HemoHIM was administrated to mice at a dose of 50 or 100 mg/kg 1h before CS exposure. HemoHIM reduced the inflammatory cell count and levels of tumor necrosis factor receptor (TNF)-${\alpha}$, interleukin (IL)-6 and IL-$1{\beta}$ in the broncho-alveolar lavage fluid (BALF) induced by CS+LPS exposure. HemoHIM decreased the inflammatory cell infiltration in the airway and inhibited the expression of iNOS and MMP-9 and phosphorylation of Erk in lung tissue exposed to CS+LPS. In summary, our results indicate that HemoHIM inhibited a reduction in the lung inflammatory response on CS and LPS induced lung inflammation via the Erk pathway. Therefore, we suggest that HemoHIM has the potential to treat pulmonary inflammatory disease such as COPD.

  • The relationship between malignancy and venous thromboembolism(VTE) has been well established. About 20% of all VTE cases are associated with cancer and thrombotic events are the second leading cause of death in cancer patients after death from cancer itself. Effective prophylaxis and treatment will reduce morbidity and may decrease overall mortality. We report a case of VTE in a patient with advanced gastric cancer who treated with low-molecular weighted heparin (LMWH). A 49-year-old man with heartburn was admitted to our hospital. On the endoscopic and radiologic imaging, the patient was diagnosed as an advanced gastric cancer with perigastric infiltration and liver metastasis. During the combination chemotherapy, he had pain and swelling of left lower leg. Doppler ultrasonography showed left posterior tibial venous thrombosis and pulmonary embolism CT showed thromboembolism in subsegmental pulmonary artery branch in right lower lobe. He was treated with LMWH, Dalteparin once daily via subcutaneous injection, and his symptoms was subsided.

  • Background : Pulmonary Langerhans cell histiocytosis forms part of a spectrum of diseases that are characterized by a monoclonal proliferation and infiltration of organs by Langerhans cells. Several organ systems may be involved in Langerhans cell histiocytosis, including the lungs, bone, skin, pituitary gland, liver, lymph nodes and thyroid. Pulmonary histiocytosis X represents 2.8% of interstitial lung disease. Here we present the clinical, radiological, therapeutic aspects of pulmonary histiocytosis X. Method : Fourteen cases of biopsy-proven pulmonary histiocytosis X patients who were diagnosed in Seoul National University Hospital during the period from January 1990 to December 1998 were analyzed retrospectively. Result : There were 12 men and 2 women in this study. The initial presenting symptoms were dyspnea, cough, chest pain, which was associated with the pneumothorax, and chest radiography abnormalities. Only 8 patients (57%) were smokers. There were 5 patients with extra-pulmonary histiocytosis (pituitary, bone, skin). Eight patients had received the chemotherapy. There were no mortalities and only one patient experienced an aggravation of symptom during the follow-up period. Conclusion : In contrast to previous reports from other countries, the patients with pulmonary histiocytosis X in this study presented with several different clinical characteristics, such as a male predominance, relatively low smoker's rate, and a better prognosis.

  • Background : Pulmonary sequestration is a rare congenital malformation, which is manifested by formation of nonfunctioning lung tissue lacking normal communication with the tracheobronchial tree. The preoperative diagnostic rate has been relatively low, and without consideration of pulmonary sequestration, unexpected bleeding from aberrant vessels may be a serious problem during the operation. The purpose of our study is to describe the clinical features of pulmonary sequestration based on a review of 15 cases treated by operation. Method : Fifteen patients with pulmonary sequestration who had undergone surgical treatment from 1991 through May 1996 at Yongdong Severance Hospital and Severance Hospital were reviewed retrospectively. Results : The mean age of the patients was 22.5 years (range 5~57), and male to female ratio was 9 : 6. Clinical presentations varied from recurrent respiratory infections such as fever, cough, and sputum or chest pain to no symptom. The chest simple X-rays showed multicystic shadow(10/15) and solid mass-like shadow(5/15). The chest CT scans, done in twelve cases, showed multicystic lesion with or without lung infiltration(8/12), solid mass-like lesion(4/12), The chest MRIs, done in three cases, revealed the aberrant arteries originating from descending aorta(2/3). Aortograms, done in four cases, showed the aberrant arteries originating from descending thoracic aorta(2/4), abdominal aorta(I/4), and intercostal artery(1/4). and the venous returns were via the pulmonary veins. Pulmonary sequestration was considered preoperatively in six patients of fifteen. Other preliminary diagnosis were lung tumor(3/15), lung abscess(21/15), bronchiectasis(2/15), and mediastinal tumor(2/15). In the operative findings, twelve cases were of intralobar type and three cases of extralobar type. The left lower lobe was most often affected(9/15) and one extralobar sequestration was in the pericardium. The aberrant arteries originated from descending thoracic aorta(6/15), abdominal aorta(1/15), internal thoracic arteries (2/15), intercostal artery(1/15), pericardiophrenic artery(1/15), but in four cases, the origins could not be defined. There was no mortality or complication postoperatively. Conclusion : In our study, preoperative diagnostic rate was relatively low, and clinical features were similar to previous reports. Preoperative vigorous diagnostic approach including aortography is strongly advocated not only for its diagnostic value, but also for accurate localization of the aberrant vessels, which is major concern to surgical procedure.

  • Background : In order to elucidate one of the pathogenic mechanisms of ARDS associated with pulmonary surfactant and oxidant injury, acute lung injury was induced by N-nitroso N-methylurethane (NNNMU). In this model, the role of phospholipase $A_2$ ($PLA_2$), surfactant, gamma glutamyl transferase (GGT) and morphology were investigated to delineate one of the pathogenic mechanisms of ARDS by inhibition of $PLA_2$ with high dose of dexamethasone. Method: Acute lung injury was induced in Sprague-Dawley rats by NNNMU which is known to induce acute lung injury in experimental animals. To know the function of the alveolar type II cells, GGT activity in the lung and bronchoalveolar lavage was measured. Surfactant phospholipid was measured also. $PLA_2$ activity was measured to know the role of $PLA_2$ in ARDS. Morphological study was performed to know the effect of $PLA_2$ inhibition on the ultrastructure of the lung by high dose of dexamethasone. Results : Six days after NNNMU treatment (4 mg/kg), conspicuous pulmonary edema was induced and the secretion of pulmonary surfactant was decreased significantly. In the acutely injured rats' lung massive infiltration of leukocytes was observed. At the same time rats given NNNMU had increased $PLA_2$ and GGT activity tremendously. Morphological study revealed bizarre shaped alveolar type II cells and hypertrophied lamellar bodies in the cytoplasm of the alveolar type II cells. But after dexamethasone treatment (20 mg/kg, for six days) in NNNMU-treated rats, these changes were diminished i.e. there were decrease of pulmonary edema and increase of surfactant secretion from alveolar type D cells. Rats given dexamethasone and NNNMU had decreased $PLA_2$ and GGT activity in comparison to NNNMU induced ARDS rats. Conclusion : Inhibition of $PLA_2$ by high dose of dexamethasone decreased pathological findings caused by infiltration of leukocytes and respiratory burst. Based on these experimental results, it is suggested that an activation of $PLA_2$ is the one of the major factors to evoke the acute lung injury in NNNMU-induced ARDS rats.

  • Hypereosinophilic syndrome (HES) is characterized by the presense of hypereosinophilia with evidence of target organ damage. We report a patient diagnosed with eosinophilic cystitis and HES. A 7 year old boy had hematuria, dysuria, and increased urinary frequency for 1 day. Laboratory examinations revealed hypereosinophilia (eosinophils, $2,058/{\mu}L$), hematuria, and proteinuria. Abdominal sonography revealed diffuse and severe wall thickening of the bladder. The patient was treated initially with antibiotics. However, his symptoms did not improve after 7 days. A computed tomography scan demonstrated severe wall thickening of the bladder and the hypereosinophilia persisted (eosinophils, $2,985/{\mu}L$). The patient complained of chest discomfort, dyspnea, epigastric pain, and vomiting on hospital day 10. Parasitic, allergic, malignancy, rheumatologic, and immune workups revealed no abnormal findings. Chest X-rays, electrocardiography, and a pulmonary function test were normal; however, the hypereosinophilia was aggravated (eosinophils, $3,934/{\mu}L$). Oral deflazacort was administered. A cystoscopic biopsy showed chronic inflammation with eosinophilic infiltration. The patient's respiratory, gastrointestinal, and urinary symptoms improved after 6 days of steroids, and he was discharged. The eosinophil count decreased dramatically ($182/{\mu}L$). The hypereosinophilia waxed and waned for 7 months, and the oral steroids were tapered and stopped. This case describes a patient diagnosed with eosinophilic cystitis and HES.
