unstimulated migration of granulocytes toward serum or plasma and granulocyte activation without migration were accompanied , at three hours , by more modest increases in 6-keto-pgf1 alpha ( 296.5 +/- 46.4 ; 128.0 +/- 38.6 , and 236.7 +/- 47.0 ng/ml , respectively ) and , in the absence of granulocytes or in the absence of endothelium , only minimal increases in this prostacyclin metabolite occurred ( 137.2 +/- 16.9 and 53.9 +/- 12.6 ng/ml , respectively ) .
