BACKGROUND: Conventional treatment for mesothelioma is largely ineffective. We evaluated the novel approach of adenoviral gene transfection of PTEN gene in mesothelioma cancer cell lines, inflammatory and epithelial subtype, which are sensitive to adenoviral p53. MATERIAL AND METHOD: Binary adenoviral PTEN and LacZ (Ad/GT-LacZ and Ad/GV16) vectors were used for transduction of the mesothelioma cell lines, REN (p53 sensitive). Protein levels were determined by Western blotting assay. Apoptosis was assessed by fluorescence-activated cell sorter analysis of subdiploid populations. Cell viability was determined with the XTT assay. Statistical analysis was performed with analysis of variance and the Student t test. RESULT: 72 hours after the treatment of adenoviral PTEN gene, cell killing were 32.9% for REN compared to control cell (2.5%) at MOI of 20. Also we observed the over-expression of proapoptotic protein, bax and decreased expression of bcl-2 protein in REN cells. But the expression of BCL-xl, Bak, Bad proteins were not altered. CONCLUSION: Adenovirus Pten-mediated overexpression of the Bax gene induces apoptosis and decreased cellular viability in p53-sensitive mesothelioma cells. These data suggest that the transfection of PTEN gene may represent a alternative gene therapy strategy to treat mesothelioma.

BACKGROUND: Hemoptysis is a common clinical symptom, responsible for 11% of admission to the hospital chest service. Correct diagnosis, accurate localization of the bleeding source and proper management are imperative to reduce the risk of massive hemoptysis. We performed the study to define the optimal time of fiberoptic bronchoscopy in 63 patients with hemoptysis admitted to Kyung Hee University Hospital between Aug 1989 and Aug1992. METHODS: Retrospective analysis of medical records concerning the cause, amount, duration of hemoptysis and the timing of fiberoptic bronchoscopy in 63(M:F=36:27) patients. RESULTS: 1) The main causes of hemoptysis were pulmonary tuberculosis(52.4%) bronchiectasis(27.0%) and lung cancer(11.1%). 2) The bleeding sites were localized in 26 Patients(41.3%). 3) The rates of localization of bleeding site were not related to the amount and duration of hemoptysis. 4) The rates of localization of bleeding site were 61.8%(21/34) during hemoptysis,18.2%(122) within 24hr after resolution of hemoptysis, 14.3%(1/7) thereafter. CONCLUSION: Early bronchoscopy, especially during hemoptysis may show higher rates of successful localization than delayed bronchoscopy.
