Backround: Pulmonary aspergilloma is a potential life-threatening disease resulting from massive hemoptysis. Pulmonary aspergilloma has been treated surgically for many years, however, it has also had higher risk of mortality and complication rate. The purpose of this study is to analyze the operative methods and the types of complications. Material and Method: Sixty patients who underwent surgical resection for pulmonary their medical reconrds. Result: The mean age was 46.3$\pm$13.4 years(range 20 to 76 years). The most common clinical presentation was hemoptysis which occurred in 48 patients(80%). Pulmonary tuberculosis was the most common pre-existing disease, occurri9ng in 28 patients(46.7%). The other associated lung diseases were bronchiectasis(n=11), silicosis(n=2), and chronic pnumonia(n=1). Operative proceudres wer lobectomy in 35 patients, pneumonectomy in 6, segmentectomy in 5, lobectomy and thoracoplasty in 3, segmentectomy and thoracopasty in 1, and cavernostomy in 10. The operative mortality was 6%(n=3) in lung resection patients but 0% in cavernostomy patients. The most common complications were prolonged air leakage, wound infection and postoperative bleeding. Conclusion: In most cases of pulmonary aspergilloma surgical resectin remains the only effective therapy. However, cavernostomy may be more effective for pulmonary aspergilloma patients with decreased pulmonary functions and for patients with high risk for lung resection.

Pulmonary paragonimiasis is a relatively rare cause of lung disease revealing a wide variety of radiologic findings, such as air-space consolidation, nodules, and cysts. We describe here a case of pulmonary paragonimiasis in a 27-year-old woman who presented with a 2-month history of cough and sputum. Based on chest computed tomography (CT) scans and fluorodeoxyglucose positron emission tomography (FDG-PET) findings, the patient was suspected to have a metastatic lung tumor. However, she was diagnosed as having Paragonimus westermani infection by an immunoserological examination using ELISA. Follow-up chest X-ray and CT scans after chemotherapy with praziquantel showed an obvious improvement. There have been several reported cases of pulmonary paragonimiasis mimicking lung tumors on FDG-PET. However, all of them were suspected as primary lung tumors. To our knowledge, this patient represents the first case of paragonimiasis mimicking metastatic lung disease on FDG-PET CT imaging.

Paragonimiasis was one of the most common causes of cavitary lung lesions until the 1960s, but now it has become a very rare disease in Korea. A 16-year-old boy presented with hemoptysis and several days of cough. His plain chest radiograph showed nodular opacity with a cavity in the left upper lung region. Although his symptoms disappeared after taking antituberculous drugs, his plain chest radiograph and computed tomography images after completion of therapy showed a new nodule with a cavity in the left lung field. Through video-assisted thoracoscopic wedge resection, Paragonimus eggs were found in the lung tissues.

MicroRNAs (miRNAs) are a class of naturally occurring small non-coding RNAs of about 22 nucleotides that have recently emerged as important regulators of gene expression at the posttranscriptional level. Recent studies provided clear evidence that microRNAs are abundant in the lung, liver and kidney and modulate a diverse spectrum of their functions. Moreover, a large number of studies have reported links between alterations of miRNA homeostasis and pathological conditions such as infectious diseases, sickle cell disease and endometrium diseases as well as lung, liver and kidney diseases. As a consequence of extensive participation of miRNAs in normal functions, alteration and/or abnormalities in miRNAs should have importance in human diseases. Beside their important roles in patterning and development, miRNAs also orchestrated responses to pathogen infections. Particularly, emerging evidence indicates that viruses use their own miRNAs to manipulate both cellular and viral gene expression. Furthermore, viral infection can exert a profound impact on the host cellular miRNA expression profile, and several RNA viruses have been reported to interact directly with cellular miRNAs and/or to use these miRNAs to augment their replication potential. Here I briefly summarize the newly discovered roles of miRNAs in various human diseases including infectious diseases, sickle cell disease and enodmetrium diseases as well as lung, liver and kidney diseases.

Little is known of the lung cellular immunophenotypes in patients with non-tuberculous mycobacterial lung disease (NTM-LD). Flow-cytometric analyses for the major myeloid and lymphoid cell subsets were performed in less- and more-diseased areas of surgically resected lungs from six patients with NTM-LD and two with Pseudomonas aeruginosa lung disease (PsA-LD). Lymphocytes, comprised mainly of NK cells, CD4⁺ and CD8⁺ T cells, and B cells, accounted for ~60% of all leukocytes, with greater prevalence of T and B cells in more-diseased areas. In contrast, fewer neutrophils were found with decreased number in more-diseased areas. Compared to NTM-LD, lung tissues from patients with PsA-LD demonstrated relatively lower numbers of T and B lymphocytes but similar numbers of NK cells. While this study demonstrated a large influx of lymphocytes into the lungs of patients with chronic NTM-LD, further analyses of their phenotypes are necessary to determine the significance of these findings.

To confirm diagnosis and to set proper therapeutic strategy, open lung biopsies were done in 57 patients who were suspected for diffuse interstitial lung disease from January 1985 to December 1994. Among them, 35 were male and 22 were female[M:F=l.6: 1 and mean age of the patients is 53.5$\pm$ 2.3[24-81 years. Tissue for histologic studies were obtained from left lung in 33, from right lung in 24according to the distributions of the pathology. Preoperative diagnostic work-up`s were chest X-ray, CT[HRCT scan, sputum study, bronchoscopy[BAL, TBLB and PTNA and all of them were unsuccessful to confirm diagnosis. In comparison of pulmonary function tests between preoperative and postoperative values, there were no significant differences in FVC, FEV1, FEV1/FVC[p 0.05 but in AaDO2[p[0.05 . Postoperative complications including atelectasis, wound infection, pulmonary edema and respiratory insnfficiency, were shown in 5 cases[8.8% , and two of them were died of respiratory failure and sepsis[mortality rate 3.5% . Pathologic diagnosis was confirmed in 53 cases postoperatively but it was undetermined in 4[diagnostic yield rate 93.0% . In comparison between preoperative clinical diagnosis and postoperative pathologic diagnosis, new diagnosis were made in 17 cases[29.8% and preoperative tentative diagnosis were confirmed histologically in 36 cases[63.2% . In 4 cases[7.0% , however, diagnoses were not confirmed after biopsies. Therapeutic plans were reset in 46 cases[80.7% in accordance with the final diagnosis.In conclusion, open lung biopsy is recommended for a specific diagnosis and proper therapeutic plan in diffuse interstitial lung diseases because of its high diagnostic yield Irate and it`s relatively low morbidity and mortality rate in these tompromised patents.

We have performed eight, single transplantations of right lung in dogs from September, 1988 to March 1989 at the Thoracic & Cardiovascular Surgical department, Yonsei University, College of Medicine, Seoul, Korea. We wrapped bronchial anastomosis site with great omentum and used cyclosporin in preoperative and postoperative periods in seven cases except one. The one without wrapping the bronchial anastomotic site with omentum and using cyclosporin died due to bronchial anastomotic site rupture in postoperative fourth day. If there is no reason to choose one side over the other, we would generally choose to do left-sided transplant as this is technically somewhat easier because of the long length of recipient bronchus and the ease of clamping the left atrium proximal to the pulmonary veins. The right atrium limits the amount of left atrium that can have incorporated into the clamp proximal to the pulmonary veins on the right side. But we had chosen to do right-sided transplant of lung because we must take variable technical experiences on right sided lung transplant in dogs. We have to anastomose one of pulmonary vein and left atrial wall on right-sided transplant easily only with double ligation of one pulmonary vein because right atrium limited the clamp of left atrium proximal to pulmonary veins with decreased venous return and cardiac output in some dogs. All seven dogs with right-sided lung transplant had survived more than one day with good condition except one. The one dog have to be sacrificed to evaluate the difference between the gas analysis in pulmonary venous and arterial blood in post-operative eight hours. We found hemorrhagic pulmonary edematous changes of contralateral left lung in this dog. And also all dogs have to be sacrificed for the evaluation of surgical problems, anytime in post-operative periods without any cardiopulmonary resuscitative efforts when the general condition would be worse progressively. We found no any surgical technical errors in seven dogs except one with thrombi in suture site of left atrium. There were hemorrhagic pulmonary edematous changes of transplanted right lung in one, of contralateral left lung in one, of contralateral left lung with double ligation of its pulmonary artery in one, thrombi around left atrial sutures sites in one, multiple air leakage in one bronchial rupture in one due to rejection or infection. There were accidental extubation and delayed intubation in one and unknown cause of death in one.

We report the case of a lung transplantation patient whose cough and dyspnea symptoms improved after receiving complex Korean medicine treatment. Lung transplantation provides a solution to many end-stage patients with lung disease who are refractory to conventional treatment, but the five-year survival rate of lung transplantation remains around 50%, and even surviving patients suffer from side effects, including infection, respiratory difficulty, and gastrointestinal problems. A 66-year-old woman with rheumatoid arthritis-interstitial lung disease was advised to undergo lung transplantation surgery when she suffered from dyspnea and failing respiratory symptoms after being diagnosed with COVID-19 and contracting pneumonia. Approximately five months after receiving a bilateral lung transplantation operation, she experienced acute pulmonary thromboembolism, and even after receiving anticoagulation therapy, she still struggled with cough and respiratory difficulty. After she received complex Korean medicine treatments, including herbal medicine, cupping therapy, and electrical moxibustion, we observed a decrease in inflammation, alleviation of symptoms such as cough and dyspnea, and improvement of pulmonary function and exercise capacity.

Nocardia, aerobic members of the order of Actinomycetaceae, produces infections in human lung. Nocardial infection is associated with underlying diseases of immuno-suppression or treatment with corticosteroid. It is difficult to detect Nocardia by sputum examination or histologic sections and it has rarely been diagnosed by fine needle aspiration of the lung. We describe a case of pulmonary nocardiosis in a 72 year-old man, diagnosed by fine needle aspiration, which was confirmed by culture of aspirates. The aspirates showed neutrophil-predominant inflammatory cells with microorganisms demonstrated by Gomori methenamine silver and Gram stain. The organisms had characteristic long blanching filamentous structures. The lesions on chest X-ray were in resolution with antimicrobial therapy.
