【Abstract】 Objectives:To introduce the author’s experiences in bioassay of platelet activating factor with thin layer chromatographic separation and platelet aggregation method, and to discuss probable problems in the process. Methods and Results:The method was used in determining portal venous blood samples from swine models of acute severe pancreatitis, control value were 0.79~1.65 pmol/L, in acute severe pancreatitis, mean blood level of platelet activating factor may be as high as 14.75 pmol/L. Conclusions: Thin layer chromatography separation and platelet aggregation assay were suitable for the determination of platelet activating factor, the results were satisfactory in case of standardized operation.更多还原
