[The characteristics of the membrane-destabilizing mechanisms in chronic suppurative and suppurative-polypous sinusitis in children].

: It is found that chronic purulent and pyopolypous sinusitis in children causes activation of lipid peroxidation and endogenic phospholipases in red cell membranes. There are shifts in structural and functional pattern of cytomembranes in inflammation focus (exudate from the sinuses). Membrane destabilization was maximal in pyopolypous sinus inflammation.
