title: [Characteristics of the membranes and functional activity of phagocytic alveolar macrophages].
abstract: Alveolar macrophages (AM) accumulate products of lipid peroxidation (PLP) in the time of phagocytosis of zymosan particles (ZP) during 4 hours, that lead to increase of lipid viscosity and decrease surface membrane area, which were studied by fluorescent probes pyrene and HSPH-14. Preliminary stimulation of AM by i/v ZP-injection of A(100 mg/kg before 5 days) lead to a decrease of lipid membrane viscosity and intensification of AM functional activity. During phagocytosis of ZP experimental cells accumulate much less PLP, than control cells, and promote support of viscosity on a more low level, and functional activity (phagocytic, adhesion properties)--on more high level, than in control cells.
