Ginkgolide BN 52021 protects against hemorrhagic shock-induced renal injury in rats.

Degree of renal damage in experimental untreated and treated hemorrhagic shock was estimated in light microscopy. Histological preparations were scored with a semiquantitative scale concerning the changes which are typical for the acute renal failure. It was found that an early treatment with the PAF-receptor antagonist (ginkgolide BN 52021) considerably reduced morphological changes observed in rat kidney in hemorrhagic shock, comparing with untreated shock and in shock treated with a polyelectrolyte solution.
