Popis: The soluble adhesion molecules P-selectin (sP-selectin) and intercellular adhesion molecule-1 (sICAM-1) are derived from platelets and endothelial cells. Circulating concentrations of these soluble adhesion molecules are raised in patients with atherosclerosis and following percutaneous transluminal coronary angioplasty (PTCA). We have investigated the effects of vitamin E supplements (800 IU/day) on circulating plasma ICAM-1 and P-selectin levels pre- and post-PTCA. Patients, randomized to group, were pre-treated with vitamin E or placebo (soybean oil) for 1 month before routine PTCA. Plasma sICAM-1 and sP-selectin were measured by enzyme-linked immunosorbent assay on blood taken immediately pre- and post-PTCA. Total protein and α-tocopherol were measured on the same samples. Plasma α-tocopherol concentrations increased in patients receiving vitamin E: 19·1 (1·5) [mean (standard error of the mean, SEM)] mg/mL post-PTCA versus 13·9 (0·6) mg/mL pre-PTCA ( n=23; P
