Abstract:Platelet activating factor (PAF) is a kind of inflammatory mediator. We used the method of aggregation of washed rabbit platelet to study the effect of esculentoside A (EsA) on the release of PAF from calcimycin (A23187)stimulated rat peritoneal macrophages and found that the release of PAF was inhibited by EsA in a time and dose dependent manner. The IC50 of EsA for the inhibition of PAF release was 1.5 mumol/L. Under the same condition, the release of PAF was also inhibited by mepacrine at 100 mumol/L. The results indicate that EsA is a potent inhibitor of PAF synthesis in rat peritoneal macrophages.
Keywords:Platelet activating factor (PAF)  Calcimycin (A3187))  Macrophage  Esculentoside A (EsA)
