Body fluid Lactate dehydrogenase and its isoenzyme measurement was performed in 132 patients: 8 cases with peritonitis, 21 cases with malignant ascites, 43 cases with liver cirrhosis, 48 cases with tuberculous pleuritis, 12 cases with malignant pleural effusion respectively. Body fluid protein and glucose contents, red blood cell counts, white blood cell counts, cytologic examination were also performed as a comparative study. The results were as follows: 1. Measurement of total LD and protein amount could differentiate between transudate and exudate in the ascitic fluids. 2. In the malignant exudate of ascites and pleural fluid, the activity of LD2 isoenzyme was statistically increased compared with that of inflammatory exudate and the activity of LD4 isoenzyme was also increased compared with that of serum(P<0.05). 3. The inflammatory exudate of pleural fluid and ascites demonstrated the increase of LD5 isoenzyme activity stastistically compared with that of serum and malignant exudate(P<0.05). 4. A difference of total LD activity between malignant ascites and inflammatory ascites was significant statistically, while this was not observed in the pleural exudate. 5. Total LD and LD5 isoenzyme activity didn't correlated with the number of white blood cells in the exudate.

Background: The causes of the pleural effusion are remained unclear in a the substantial number of patients with exudative effusions determined by an examination of the fluid obtained via thoracentesis. Among the various tools for diagnosing exudative pleural effusions, thoracoscopy has a high diagnostic yield for cancer and tuberculosis. Medical thoracoscopy can also be carried out under local anesthesia with mild sedation. The aim of this study was to determine diagnostic accuracy and safety of medical thoracoscopy. Methods: Twenty-five patients with exudative pleural effusions of an unknown cause underwent medical thoracoscopy between October 2005 and September 2006 in Konyang University Hospital. The clinical data such as age, gender, preoperative pulmonary function, amounts of pleural effusion on lateral decubitus radiography were collected. The vital signs were recorded, and arterial blood gas analyses were performed five times during medical thoracoscopy in order to evaluate the cardiopulmonary status and acid-base changes. Results: The mean age of the patients was 56.8 years (range 22-79). The mean depth of the effusion on lateral decubitus radiography (LDR) was 27.49 mm. The medical thoracoscopic pleural biopsy was diagnostic in 24 patients (96.0%), with a diagnosis of tuberculosis pleurisy in 9 patients (36%), malignant effusions in 8 patients (32%), and parapneumonic effusions in 7 patients (28%). Medical thoracoscopy failed to confirm the cause of the pleural effusion in one patient, who was diagnosed with tuberculosis by a pericardial biopsy. There were no significant changes in blood pressure, heart rate, acid-base and no major complications in all cases during medical thoracoscopy (p>0.05). Conclusions: Medical thoracoscopy is a safe method for patients with unknown pleural effusions with a relatively high diagnostic accuracy.

Background : The changes of the composition in the T-lymphocyte are important as an immunological abnormality in the pathogenesis of tuberculosis. Previously, the second type of TCR dimer(${\gamma}{\delta}$ T lymphocyte) that did not express CD4 or CD8 molecules was found. In other reports the presence of this type of lymphocytes was increased in the initial stage of tuberculous infections. Method : To determine whether there are some differences in the T-lymphocyte subsets in the peripheral blood or pleural effusion between pleural tuberculosis and other pleurisy. Thirty patients with pleural effusion among the forty-nine patients were examined T-lymphocyte subset analysis(CD4+T-cell,CD8+ T-cell,${\gamma}{\delta}$ T-lymphocytes) with anti- Leu4, anti-Leu3a, anti-Lea2a, anti HLA-DR and anti-TCR-${\gamma}{\delta}$-1(Becton & Dickinson Co.). Results : The average age of the patients was 50 years old(17-81year). There were 33 males and 16 female patients. Patiensts with tuberculosis are 30cases(tuberculous pleurisy 15), lung cancer 12cases(malignant effusion 9) and pneumonia 7cases(parapneumonic effusion 6cases) In T lymphocyte subsets of pleural effusion, helper T lymphocyte(54.6 + 13.8 %) of tuberculous pleurisy was higher than that(36.2 + 25.3 %) of non-tuberculous pleurisy(p=0.04). The peripheral blood ${\gamma}{\delta}$ T-lymphocytes in tuberculousis was insignificantly higher than non-tuberculous patients(p= 0.24). The peripheral blood ${\gamma}{\delta}$ T-lymphocytes and pleural ${\gamma}{\delta}$ T-Iymphocytes in tuberculous pleurisy was insignificantly higher than in non-tuberculous pleurisy(p= 0.16, p= 0.12). Conclusion : The percentage of -${\gamma}{\delta}$ T lymphocytes among the total T-lymphocytes is not significantly increased in the peripheral blood or pleural effusion of the pleural tuberculosis. ${\gamma}{\delta}$ T lymphocytes is less useful as a diagnostic method of pleural tuberculosis.

An 8-year old intact female poodle was presented to clinics due to abdominal distension, anorexia, and labored breath associated with pleural effusion. Intra-operative findings revealed multiple neoplasm of the greater omentum, involving anterolateral abdominal wall, sterna surface in the pleural cavity and diaphragm. These masses were 0.1~0.5 cm in diameter and extended to ovaries, pancreas, and serosal surface of stomach. Microscopically, most neoplastic cells had oval nuclei with prominent nucleoli and abundant eosinophilic cytoplasm. In deeper area, neoplastic acinus or glandular structures showed invaginated growth resembling adenocarcinoma. High mitotic figures were observed. By immunohistochemistry, the neoplastic cells were strong positive both cytokeratin and vimentin. The present case described for malignant mesothelioma in a dog. Our findings might be helpful for diagnosis and information and helped the clinics choose the treatment including chemotherapy such as cisplatin.

Background: The intrapleural instillation of tetracycline for pleural sclerosis had been most commonly used in patients with symptomatic malignant pleural effusion or recurrent pneumothorax for a long time. Unfortunately, at a time of expanding use of this agent, the production of injectable tetracycline hydrochloride used for pleurodesis was discontinued by its sole manufacturer in mid-1991 because the manufacturer was unable to meet US Food and Drug Administration purity standards. So we performed a preliminary study of doxycycline, as a alternative pleural sclerosant on rabbit pleura and compared its efficacy with that of tetracycline. Method: Eighteen New Zealand white rabbits weighing 2 to 3kg(mean 2.6kg) were devided into three groups. In each groups, one tetracycline(20 mg/ml/kg) and two doxycycline solutions(7 mg/ml/kg and 20 mg/ml/kg) instillated into the right pleural space through an 18-gauge angiocath with care to prevent pneumothorax. All rabbits were sacrificed after 28 days. Results: 1) In the group of tetracycline 20 mg/ml/kg(six rabbits), five rabbits showed partial pleural symphysis with several fibrous bands, and one rabbit died on 22th day. 2) In the group of doxycycline 7 mg/ml/kg(six rabbits), three rabbits showed partial pleural symphysis and the other three rabbits showed complete pleural symphysis without necrosis of underlying parenchymal lung tissue. 3) In the group of doxycycline 20 mg/ml/kg(six rabbits), two rabbits showed complete pleural symphysis without lung necrosis, another two rabbits showed complete pleural symphysis with lung necrosis, and the other two rabbits died on 4th and 13th day, respectively. Conclusion: We concluded that doxycycline is a highly effective sclerosing agent having stronger pleurodesis effect with that of tetracycline by dose base and its optimal dosage was considered as 7 mg/ml/kg with minimal complications.

Background : The intrapleural hypofibrinolysis is caused by mainly excessive concentration of pleural plasminogen activator inhibitor-1 antigen(PAI-1 Ag), which binds tissue type plasminogen activator. In pleural inflammation induced by sclerosing agents for pleurodesis, levels of pleural PAI-1 antigen increase in relation to decreasing D-dimer levels. It has been known that the pleural mesothelial cells have the capability of secreting PAI-1 Ag in response to inflammation in vivo. Therefore, we estimated whether pleural inflammation changes the balance between fibrinolytic and coagulative properties in exudative pleural effusions. Method : The thirty cases was included in our study. We determined the pleural levels of glucose, lactic dehydrogenase(LDH), pH and the counts of white blood cell(WBC), polymorpho leukocyte(PMN), lymphocyte as the parameters of pleural inflammation and cellular components of pleural fluid. The plasma level of fibrinogen in fluid and the neutrophil count in blood were determined. The levels of D-dimer, PAI-1 Ag and thrombinantithrombin III complex(TAT) were determined by ELISA(Behring, Marburg, Germany). Result : The causes of pleural effusion were as following : tuberculous in 14 cases, malignant in 10 cases and parapneumonic in 6 cases. The levels of pleural D-dimer, PAI-1 Ag and TAT was significantly higher than that of plasma(p<0..001). The severity of pleural inflammation did not correlated with pleural D-dimer, PAI-1 Ag, TAT and their plasma levels. But the level of pleural TAT correlated with pleural WBC and lymphocyte count. Conclusion : We found that the severity of pleural inflammations did not correlated with pleural D-dimer, PAI-1 Ag, TAT and the possibility of local production of PAI-1 antigen is present.

Epithelioid hemangioendothelioma (EH) is a rare borderline malignant tumor which originating from vascular endothelial cells and occurs in many organs such as soft tissues, lung, liver and bone. But, pulmonary EH which simultaneously involves pleura and liver is very rare. In the present report, we describe an uncommon case of EH involving the lung, pleura and liver in a 26-year-old woman. Chest CT showed single nodule in right upper lobe with large amount of pleural effusion at ipsilateral side and abdominal CT multiple round low densities in liver. The EH was confirmed by microscopic analysis and immunohistochemical staining of CD34+ from open lung biopsy specimen.

Over the past few years, video-assisted thoracic surgery [VATS] has been used increasingly for intrathoracic pathologic problems as a less invasive operative techniques. Today it is viewed as a sparing and safe alternative to thoracotomy for a wide spectrum of indications. Using video-assisted operative thoracoscopy, we performed consecutive 150 operations on 148 patients during the initial 2 years of our experience from July 1992 with the following indications: pneumothorax [n=53], hyperhidrosis [n=29], mediastinal mass [n=23], pleural disease [n=13], diffuse parenchymal or interstitial lung disease [n=12], benign pulmonary nodule [n=7], metastatic lung mass [n=3], primary lung cancer [n=3], bronchiectasis [n=2], malignant pericardial effusion [n=2], endobronchial tuberculosis [n=1], esophageal achalasia [n=1], and pulmonary parenchymal foreign body [n=1]. There were no death, and overall complicaton rate was 24.0%[n=36]. The most prevalent complication was persistent air leakage [longer than 5 days] in 14 cases [9.3%]. Persistent pleural effusion [longer than 5 days] occurred in 6 cases [4.0%]. Six patients were converted to an open thoracotomy because of inability to control the operative bleeding [n=3], failed adhesiolysis in bronchiectasis [n=2], and radical excision of an lung cancer [n=1]. Pneumothorax recurred in 3 cases[2.0%]. Other complications were Horner`s syndrome, diaphragm tears, temporary phrenic nerve palsy, hoarseness, subsegmental atelectasis, transient respiratory difficulty, and esophageal mucosal tear. The advantages of this minimally traumatizing operative technique lie in improved visualization, decreased pain, shortened hospital stay, and less postoperative morbidity. The indications of VATS has been extended increasingly to intrathoracic pathologies, but its role in the managements of primary lung cancer and esophageal disease remains to be defined.

Background : Lung cancer is the leading cause of malignant pleural effusions, which is currently most commonly treated using pleurodesis via bedside thoracostomy. Several agents had been used for the treatment of pleural sclerosis, but with differing efficacies and associated side effects. Our purpose with this study was to compare the efficacy, side effects and disease free survival times of patients being treated with OK-432 and doxycycline sclerotherapy in lung cancer induced malignant pleureal effusions. Materials and Methods : 79 patients who underwent pleurodesis with OK-432 and doxycycline, between Jan.1994 and Aug. 2001, were retrospectively reviewed. Response 30 days following pleurodesis were determined from chest radiographs, with the disease free survival time being evaluated according to the response. Results : The success rates, 30 day followint pleurodesis, with OK-432 and doxycycline 83 and 87%, respectively (p=0.677). With regard to the side effects, fever was more common when OK-432 was used (59%, p=0.001), and pain was more common with doxycycline use (73%, p=0.008). There was no significant difference in disease free survival times between OK-432 (13.6 Months) and doxycycline (11.6 Months) (p=0.532). Conclusion : with the use of OK-432, for pleurodesis, was as effective as doxycycline, can be considered as an alternative treatment for malignant effusion in patients with lung cancer.

Malignant melanoma develops from the melanocyte and the most common primary site is skin, followed by mucosa and retina. Even though any other tissue where melanocytes reside could be the primary site of the malignant melanoma, the one developed in the mediastinum is rarely reported. We experienced a patients of 54 years old woman whose initial symptom was progressive dyspnea for one month, and proved to have the anterior mediastinal mass with pleural effusion and the small mass in the abdominal soft tissue. The needle aspiration biopsy from the mediastinal mass showed the consistent findings with malignant melanoma. We concluded the mediastinum was the primary site of the malignant melanoma of this patient because we couldn't find any other evidence of primary tumor in skin, oral and gastrointestinal mucosa, and retina. She has been treated with combined chemotherapy with dacarbazine, cisplatin and vinblastine. Her symptom was improved after chemotherapy and follow up chest CT after three cycles of chemotherapy showed the decreased tumor size in the mediastinum.
