Lipid hydroperoxides play an important role in various pathophysiological processes. Therefore, a simple model for organic hydroperoxides could be helpful to monitor the biologic effects of endogenous and exogenous compounds. The electron paramagnetic resonance (EPR) spin-trapping technique is a useful

The effects of tannins and related polyphenols on KO2- and compound 48/80-induced histamine release from rat peritoneal mast cells were examined. Pretreatment with hydrolyzable tannins (1-100 microM) significantly inhibited KO2-induced histamine release. Dimeric ellagitannins, which have hexahydroxydiphenoyl (HHDP) and valoneoyl
