[Lipids in the exhaled air condensate of pneumonia patients]
Abstract:
Lipid composition of exhaled air condensate (EAC) was assessed by thin layer chromatography in patients with pneumonia and normal subjects. In parallel with this, diene conjugates and diene ketones were assessed by spectrophotometry. Berhan's principle was for the first time used for noninvasive obtaining of EAC from each lung separately. Decreased percentage of phospholipids and increased level of free fatty acids in EAC of patients with massive pneumonia may be an evidence of disordered pulmonary surfactant, and an increase of the intermediate products of lipid peroxidation indicate the cause of these changes.
