ABSTRACT

Histological analysis of lung and kidney after multiple PAF i.v. injection into rabbits was performed. Under these conditions the effect of previously injected of verapamyl, calcium channel blocker, was studied. It was shown that RAF causes inflammatory reaction with cell infiltration, microcirculation disorders and thrombosis in lung and kidney, which may classify as interstitial nephritis, pneumonitis and vasculitis. Verapamyl inhibits vasospasm, abolishes fibrinogen but does not affect cell infiltration and oedema development. Thus, Ca channel-dependent mechanism of vasospasm and thrombogenesis induced by PAF in vivo is confirmed. Perhaps, another possibilities for realising PAF action in vivo may occur.
