Outline of Final Research Achievements |
The prognosis of patients with pneumothorax combined with pulmonary emphysema is poor due to destruction of the lung. We reported that intrapleural administration of gelatin-embedded, sustained-release basic fibroblast growth factor induced lung regeneration in an elastase-induced pulmonary emphysema model in rats.Phase II clinical trial was performed to lung regeneration with sustained-release basic fibroblast growth factor for the purpose of closing fistula and preventing recurrence. Fifteen pneumothorax patients with advanced pulmonary emphysema were enrolled. In all cases, air leakage were stopped and there were no serious side effects. The effect of regeneration was evaluated by the ratio of the low attenuation area of chest CT (LAA%). LAA% decreased significantly from 46.8 ± 20.9% before treatment to 32.3 ± 20.5% after treatment (p=0.0215).It was suggested that intrapleural administration of sustained-release basic fibroblast growth factor induced lung regeneration.
