Airway eosinophilia has been proposed as a major pathogenetic event in bronchial asthma and airway hyperresponsiveness. Intravenous injection of Sephadex G200 in rats induces pulmonary and blood eosinophilia and alters pulmonary responsiveness to 5-hydroxytryptamine. To characterize the early pulmonary inflammatory responses following Sephadex administration, and to determine the timing of ...

Pulmonary alveolar proteinosis is a relatively rare, diffuse lung disease for which whole lung bronchopulmonary lavage is an effective treatment. The possibility of spontaneous remission also exists, but few actual cases have been described. This report describes a 56-year-old woman in whom pulmonary alveolar proteinosis was diagnosed 18 years earlier ...
Gonzalez E B - - 1987
We studied a patient with relapsing idiopathic chronic eosinophilic pneumonia. Each one of four attacks observed during a 4-year period was characterized by dyspnea, wheezing, peripheral blood eosinophilia, elevated serum IgE levels, and pulmonary infiltrates. Glucocorticoid therapy caused prompt resolution of symptoms and disappearance of blood eosinophilia and pulmonary shadowing. ...
Sastre J - - 1987
We describe a patient with pulmonary ceroid histiocytosis. Skin pigmentation, chest x-ray film and laboratory findings were normal. Only pulmonary function tests were abnormal (TLC = 63 percent, DLco = 52 percent). Based on these functional data, the patient was submitted to a lung biopsy by thoracotomy. Brown pigmented histiocytes ...

A 26-year-old woman with extra-pulmonary Wegener's granulomatosis was treated with cyclophosphamide for 3.25 years, cumulated dose of 91 g. Six months before cessation of therapy discrete radiological signs of apical fibrosis appeared. The changes were progressive regardless of discontinuation of cyclophosphamide and led to severe restrictive ventilatory defect.
