The contents of 6-keto-prostaglandin F<SUB>1&alpha;</SUB> (6KF<SUB>1&alpha;</SUB>) and thromboxane B<SUB>2</SUB> (TXB<SUB>2</SUB>) in mouse peritoneal macrophages were determined by radioimmunoassay. When indomethacin at a final concentration of 0.1 mM was added at each stage in the preparation of macrophage samples, i.e. (I) before incubation of peritoneal exudate cells in glass dishes to prepare macrophage monolayers, (II) before harvest of macrophages from the glass surfaces, (III) before sonication of macrophage suspensions, and (IV) before centrifugation of sonicated macrophage solutions, large differences were detected in the contents of 6KF<SUB>1&alpha;</SUB> and TXB<SUB>2</SUB> at each stage. These results suggested that physical stimulation during the preparation of samples resulted in increases of 6KF<SUB>1&alpha;</SUB> and TXB<SUB>2</SUB> production by macrophages.
