1.DNA analysis of squamous cell carcinoma and basal cell carcinoma of the skin using flow cytometry.
Korean Journal of Dermatology 1991;29(3):384-390
DNA flow cytometric analysis was performed on paraffin-embedded tissue from 10 cases of squamous cell eareinoma (SCC) and 10 cases of basal cell carcinoma(BCC). These results were applicable to do a better prognosis in BCC than SCC. In 10 cases of SCC, the DNA index was 1.34 and aneuploidy was identified in 9. In 10 cases of BCC, the DNA index was 1.30 and aneuploidy was identified in 6.

We report a case of generalized plane xanthoma which showed no-rmolipoproteinemia and was not associated with unerlying disorders or other type of xanthomas. A 48-year-old female has noticed well defined, slightly elevated, yellowish plaques which occurred on the periorbital areas, sides of the neck, scapular areas, anterior chest, buttocks and lower extremities for 3 years. Biopsy specimen taken from the neck showed perivascular accumulations of foam cells in the upper and mid dermis. Paper electrophoresis didn't, show elevation of any lipoprotein.

Genus of aspergilli are ubiquitous saprophytic molds in nature, which are recognized about 700 species, at least eight are pathologic for human. Pulmonary aspergillosis is rare disease, most frequent presenting as secondary invasion, and aspergillosis of the nasal cavity is the most common sites of the extrapulmonary aspergillosis. Predisposing factors for pulmonary aspergillosis are chronic lung disease, tuberculosis, antibiotics, cytotoxins and neoplasia, hematologic disorders, and histoplasmosis etc. Authors have experienced 10 cases of pulmonary aspergillosis and a case of aspergillosis of nasal cavity in Dept. of Pathol. Chosun univ. hospital and christian hospital from Feb. 1981 to July 1984. Patient of pulmonary aspergillosis are received surgical resection and survived well without complications.

4.Critical Care Paper Review 2012.
Tuberculosis and Respiratory Diseases 2012;73(1):1-10
Care of patients with sepsis has improved over the last decade. However, in the recent two years, there was no significant progress in the development of a new drug for critically ill patients. In January 2011, it was announced that the worldwide phase 3 randomized trial of a novel anti-Toll-like receptor-4 compound, eritoran tetrasodium, had failed to demonstrate an improvement in the mortality of patients with severe sepsis. In October 2011, Xigris (drotrecogin alfa, a recombinant activated protein C) was withdrawn from the market following the failure of its worldwide trial that had attempted to demonstrate improved outcome. These announcements were disappointing. The recent failure of 2 promising drugs to further reduce mortality suggests that new approaches are needed. A study was published showing that sepsis can be associated to a state of immunosuppression and loss of immune function in human. However, the timing, incidence, and nature of the immunosuppression remain poorly characterized, especially in humans. This emphasizes the need for a better understanding of sepsis as well as new therapeutic strategies. Many clinical experiences of the extracorporeal membrane oxygenator (ECMO) treatment for adult acute respiratory distress syndrome (ARDS) patients, which is caused by the H1N1 influenza A virus, were reported. The use of ECMO in severe respiratory failure, particularly in the treatment of adult ARDS, is occurring more commonly.

5.Different PEEP Effects on Lung Volume According to Underlying Lung Disease in Patients with Auto-PEEP.
Tuberculosis and Respiratory Diseases 2004;57(6):567-572
BACKGROUND: The effect of PEEP(ed note: Define PEEP.) on the lung volume in patients with auto-PEEP during mechanical ventilation is not even. In patients with an expiratory limitation such as COPD, a PEEP of 85% from an auto-PEEP can be used with minimal increase in the lung volume. However, the application of PEEP to patients without an expiratory flow limitation can result in progressive lung. This study was carried out to evaluate the different PEEP effects on the lung volume according to the different pulmonary diseases. METHODS: Sixteen patients who presented with auto-PEEP during mechanical ventilation were enrolled in this study. These patients were divided into 3 groups: asthma, COPD and tuberculosis sequela (patients with severe cicatrical fibrosis as a result of previous tuberculosis and compensatory emphysema). A PEEP of 25, 50, 75 and 100% of the auto-PEEP was applied, and the lung volume increments were estimated using the trapped lung volume. RESULTS: In the asthma group, the trapped lung volume was not increased at a PEEP of 25 and 50% of the auto-PEEP. This group showed a significant lung volume increment from a 75% PEEP. In the COPD group, the lung volume was increased only at 100% PEEP. In the tuberculosis sequela group, the lung volume was increased progressively from low PEEP levels. However, a significant increment of the lung volume was noted only at 100% PEEP. CONCLUSION: The effects of the applied PEEP on the lung volume were different depending on the underlying lung pathology. The level of the applied PEEP >50% of the auto-PEEP might increase the trapped lung volume in patients with asthma.

8.Pulmonary Tuberculosis and Acute Respiratory Failure.
Korean Journal of Medicine 2011;81(4):455-457
Active pulmonary TB including miliary TB is a rare primary cause of acute respiratory failure and ARDS. Therefore, little has been known about the clinical characteristics and outcomes of patients with ARDS caused by pulmonary TB. However, the incidence of TB in Korea remains in the relatively high range (90 cases per 100,000 persons in 2010), and high mortality rates (over 60%) have recently been reported in patients with ARF arising from TB. Poor prognostic factors have been evaluated are old age, delayed treatment, bad physiologic scores and combined sepsis. To improve high mortality in patients with acute respiratory failure caused by TB, further prospective studies for ventilator strategy and corticosteroid treatment are needed.

9.Nonventilatory medical treatments for acute respiratory distress syndrome and acute lung injury.
Korean Journal of Medicine 2010;79(1):1-7
Over the past decade, the ventilator management for acute respiratory distress syndrome (ARDS) and acute lung injury (ALI) have yielded improved outcomes. However, studies of the pharmacologic management of ARDS and ALI have been less effective. ARDS/ALI is a heterogeneous disease entity. Although most drug trials in ARDS or ALI have been demonstrated to be ineffective in improving outcomes, some studies suggest that targeting treatments at subgroups of patients may be beneficial. Corticosteroids have good short-term effects when given sooner than 2 weeks. Surfactant may be beneficial in direct lung injury patients. Anticoagulants may have improved outcomes in the severe patients with vascular disease. Recently, ARDS Networks reported the 'conservative fluid management strategy'. This promising fluid strategy showed beneficial effect on outcomes without serious complications. This article reviews the recent research on the Nonventilatory pharmacologic managements for patients with ARDS/ALI.

BACKGROUND: The surfactant specific proteins, SP-B and SP-C are believed to be important regulators of the surfactant function and homeostasis. Since acute respiratory distress syndrome(ARDS) is usually viewed as the functional and morphological expression of a similar underlying lung injury caused by a variety of insults, and since abnormalities in the surfactant function have been described in ARDS, the authors investigated the different effects of endotoxin and thiourea on the accumulation of mRNA encoding SP-B and SP-C. METHODS: Sprague-Dawley rats were given 5 mg/kg of an intraperitoneal endotoxin from Salmonella enteritidis and 3.5 mg/kg intraperitoneal thiourea and were sacrificed at different time periods. RESULTS: 1. The SP-B mRNA levels 6 and 24 hours after the 5 mg/kg endotoxin treatment was significantly reduced by 26.1% and 50%, respectively(P<0.01, P<0.001). 2. The SP-B mRNA levels 24 hours after the 3.5 mg/kg thiourea treatment was reduced by 9.8% and 12.5%, respectively. 3. The SP-C mRNA levels 6 and 24 hours after the 5 mg/kg endotoxin treatment was significantly reduced by 38.7% and 53.6%, respectively(P<0.01, P<0.001). 4. The SP-C mRNA level 6 hours after the 3.5 mg/kg thiourea treatment was reduced by 22.8%(P<0.05). CONCLUSION: These results indicate that the differential regulation of the hydrophobic surfactant proteins in vivo is evident, and suggest that the hydrophobic surfactant proteins might be differentially regulated during lung injury at different time periods without altering the lung wet to dry ratios. The mechanism of these alternations at the different time periods and the different kinds of etiology remain to be determined.
