It has become clear that the pathological conditions associated with an excess level of LDL are actually caused by the oxidized products of LDL [ 1 ] . More specifically, cholesterol oxides (also termed oxysterols), the oxygenated derivatives of cholesterol, appear to be the major cytotoxic components in oxidized LDL [ 2 3 ] . These compounds have a hydroxyl- or a keto- group on the cholesterol molecule.
Eicosanoids were quantified by measuring the ratio of the intensity of ions m/z 569/573 for PGF 2α , m/z 614/618 for TXB 2 and 6-keto-PGF 1α , and m/z 524/528 for PGE 2 . An analytical blank for each of these products was determined by measuring the amount of nondeuterated material, detected after extracting and analyzing 2 ml of saline to which the deuterium-labeled internal standards had been added.
Prostanoids were measured by modified stable isotope dilution assays that used gas chromatography-negative ion-chemical ionization mass spectrometry as previously described [ 23 ] . Briefly, deuterium-labeled internal standards of PGE 2 , PGF 2α , TXB 2 , and 6-keto-PGF 1α were added to the supernatants with isopropyl alcohol.
The methoxime derivative of TXB 2 , PGE 2 and 6-keto-PGF 1α was made by treatment with 2% methoxamine hydrochloride in pyridine at 70°C for 60 min, followed by evaporation of the pyridine, addition of water, and extraction with ethyl acetate.
Because PGI 2 and TXA 2 have opposing effects in vivo , we calculated the ratio of their metabolites (6-keto-PGF 1α :TXB 2 ) and found a significantly lower ratio in HF-IPF at baseline (0.
