Comparativein vitro study of the effect of contrast media on complement activity and eicosanoid content in rat blood

The study comparesin vitro effect of different contrast media on complement activity and eicosanoid content. Ionic agents (Bilignost>Iodamide>Triombrast>Hexabrix) exert pronounced complement-activating effect, while nonionic agents markedly increase blood content of arachidonic acid metabolites. The complement-activating effect of contrast media did not correlate with their ability to elevate blood content of prostaglandin F2α and leukotrienes C4 and B4.
