[Lipoxins: study of various biosynthesis pathways].

Lipoxins A4 and B4 were obtained by using soybean lipoxygenase and blood cells as a source of enzymatic activity. The conditions facilitating lipoxin biosynthesis from arachidonic acid catalyzed by soybean 15-lipoxygenase were selected. A comparative analysis of lipoxin biosynthesis with the use of cell suspensions containing only granulocytes and of mixed suspensions (platelets + granulocytes and platelets + total fraction of blood leucocytes) was carried out.
