Pathologic Changes in Baboon Lung Allografts

Lung Changes in Shock

In the very beginning stage of the lung changes are Perivascular, capillary wall edema, thickening of the interstitial, lymph and vascular dilatation.  In the late stage of the shock the following changes will occuree  Microthromboses of the lung capillary, polynulcear in­filtration into the interstitial, the existence of polynu­clear in the alveoli, proliferation of interstitial mesenchy­ma,...

Developmental changes in nitric oxide synthase isoform expression and nitric oxide production in fetal baboon lung.

Nitric oxide (NO), produced by NO synthase (NOS), plays a critical role in multiple processes in the lung during the perinatal period. To better understand the regulation of pulmonary NO production in the developing primate, we determined the cell specificity and developmental changes in NOS isoform expression and action in the lungs of third-trimester fetal baboons. Immunohistochemistry in lun...

Pathologic findings in lung volume reduction surgery.

PURPOSE Lung volume reduction surgery (LVRS) has re-emerged as an alternative in the management of patients with chronic, debilitating, emphysematous lung disease. This has permitted the formal evaluation of pathologic pulmonary changes present in these patients. This study seeks to describe systematically the pathologic findings present in patients undergoing LVRS. METHODS Tissue sections st...

Pathologic Changes of the Trachea

The tracheas of 12 patients who had undergone autopsies after percutaneous dilatational tracheot¬ omy (PDT) were analyzed macroscopically and microscopically. The puncture site of the trachea varied from just below the cricoid cartilage (two patients) to below the third ring (three patients). A fracture of one or more tracheal rings was present in 11 patients, ofwhom 2 had a fractured cri¬ coid...
