Compensatory 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 کاملQuantitative morphology of renal cortical structures during compensatory hypertrophy.
The compensatory hypertrophy in different renal cortical structures was studied in rats 10 and 21 days after unilateral nephrectomy (UNX). Quantitative morphological/stereological analysis revealed significant increases in total renal cortical volume--33% on day 10 and 48% on day 21--after UNX. These changes were paralleled by significant increments in the volumes of proximal convoluted tubule ...
متن کاملSignals and mechanisms of compensatory lung growth.
Growth of the lung involves unique structure-function interactions not seen in solid organs. Mechanical feedback between the lung and thorax constitutes a major signal that sustains developmental as well as compensatory lung growth. After the loss of lung units as by pneumonectomy (PNX), increased mechanical stress and strain on the remaining units induce adaptive responses to augment oxygen tr...

متن کاملEffects of retinoic acid on compensatory lung growth
BACKGROUND We investigated the effect of Retinoic acid in the growth of contralateral lung after pneumonectomy. METHODS Twenty one adult male Wistar albino rats from the same colony were used. They were divided into three groups (Group A, B and C). Group A undergone only left posterolateral thoracotomy. In Group B and C, the rats were subjected to left posterolateral thoracotomy and left pneu...
