Compensatory lung growth after bilobectomy in emphysematous rats
Lung volume reduction surgery (LVRS) is an option for emphysematous patients who are awaiting lung transplantation. LVRS reduces nonfunctional portions of lung tissues and favors the compensatory lung growth (CLG) of the remaining lobes. This phenomenon diminishes dyspnea and improves both the respiratory mechanics and quality of life for the patients. An animal model of elastase-induced pulmon...
متن کاملCompensatory Lung Growth After Pneumonectomy
Pneumonectomy, the surgical removal of a lung, elicits a number of anatomical changes within the thoracic cavity that augments the diffusion capacity of the remaining lung. Pneumonectomy directs the entire cardiac output into the remaining lung and creates an empty hemithorax that results in a shift of the mediastinum toward the vacated thoracic compartment. In a number of experimental animal m...
متن کاملIntratracheal Administration of Recombinant Human Keratinocyte Growth Factor Promotes Alveolar Epithelial Cell Proliferation during Compensatory Lung Growth in Rat
Keratinocyte growth factor (KGF) is considered to be one of the most important mitogens for lung epithelial cells. The objectives of this study were to confirm the effectiveness of intratracheal injection of recombinant human KGF (rhKGF) during compensatory lung growth and to optimize the instillation protocol. Here, trilobectomy in adult rat was performed, followed by intratracheal rhKGF insti...
متن کاملKeratinocyte growth factor transiently alters pulmonary function in rats.
Keratinocyte growth factor (KGF) is a mitogen for pulmonary epithelial cells. Intratracheal administration of KGF to adult rats results in alveolar epithelial type II and bronchiolar epithelial cell proliferation. While cellular responses to KGF have been intensively studied, functional consequences regarding lung function are unknown. Therefore, in this study, we sought to investigate whether ...
متن کاملFibroblast growth factor receptor-1 and neonatal compensatory lung growth after exposure to 95% oxygen.
Neonatal rats exposed to 95% oxygen (O2) for 7 days from birth had inhibited lung growth, DNA synthesis, and secondary septation. These parameters were rapidly restored by a period of recovery in air. Northern and Western blot analysis and immunohistochemistry were used to screen for the fibroblast growth factor receptor-1 (FGF-R1) and its high affinity ligand, basic fibroblast growth factor (b...
