Electron microscopic observation of pulmonary alveolar structures of laboratory mammals.

Morphological Characteristics of a Rat Model of Reexpansion Pulmonary Edema

Objective: Reexpansion pulmonary edema (RPE) is a severe disorder, and its pathophysiology is not well understood. One proposed mechanism for RPE is that chemical substances such as cytokines increase alveolar permeability. Another possible mechanism is that alveolar distention during reexpansion causes physical damage. To test the hypothesis that sudden alveolar distention damages alveolar cel...

A new myelin-like laminated body found in two cases of pulmonary alveolar proteinosis.

Electron microscopic observations were made on lung tissue, broncho-pulmonary lavage fluid and sputum in 2 cases of pulmonary alveolar proteinosis. Diagnosis was established by open lung biopsy in both cases. In Case 1 the electron microscopic samples were obtained from the surgical specimen. In Case 2 an electron microscopic observation was made only on the lavage fluid and sputum. The alveola...

Ultrastructural study on the alveolar-capillary injury with pulmonary edema induced by oleic acid in dogs.

Oleic acid induced pulmonary edema was subjected as an experimental model of ARDS. Three adult mongrel dogs were injected with 0. 09 ml/kg of oleic acid into the pulmonary artery and sacrificed 2 hours later. Light and electron microscopic studies were carried out on the pulmonary specimen. The light microsc9pic findings showed bronchovascular cuffs and alveolar flooding. The electron microscop...
