摘要：

This paper summarizes methodological aspects of measurements of eicosanoids in biological samples and describes some applications of such methods in studies on leukotriene formation in the human airways and the effects of drugs interfering with these compounds in asthmatic subjects. For estimations of in vivo production of eicosanoids, major, stable metabolites were selected for analysis in biological fluids. An enzyme immunoassay for LTE(4) was validated for use in unextracted urine samples. To monitor thromboxane production, a radioimmunoassay for 11-dehydro-TXB(2) was developed and used for measurements in samples of human plasma and urine. In vitro production of leukotrienes in chopped human lung was measured by UV-spectroscopy after extraction and separation on RP-HPLC. Corrections for losses during purification were performed with individually selected internal standards.
