Presence of immunoreactive endothelin in human plasma.

abstract：:A characteristic of the antioxidant, probucol, is its inability to inhibit apolipoprotein B fragmentation in low density lipoprotein (LDL), despite a pronounced ability to inhibit lipid oxidation on relatively lengthy exposure to Cu(II). Here we show that a short exposure of LDL to hydrogen peroxide and Cu(II) leads t...
