title: [The effect of aldehydogenic and acyl structural analogs of platelet activating factor on the formation of superoxide radicals by human blood leukocytes].
abstract: The effects of plasmalogenic and acyl structural analogs of the platelet activation factor (PAF) on the superoxide radical production by human blood leukocytes were studied. It was found that 1-O-acyl-2-acetyl-sn-glycero-3-phosphocholine and 1-O-(1'-alkenyl)-2-acetyl-sn-glycero-3-phosphocholine stimulates the production of leukocyte superoxide radicals, their activity being comparable with that of PAF. Stimulation of superoxide radical production strongly depends on the structure of the polar heads of PAF analogs. It is supposed that choline-containing plasmalogenic and acyl PAF analogs may act as specific lipid mediators of the neutrophil function.
