title: Effect of aspirin on platelet phospholipids.
abstract: It was observed that the acetylsalicylic acid "in vitro" (final concentration 10(-4) M) as well as "in vivo" (1 g of aspirin) caused a platelet phospholipids variation which basically consisted of: 1. A diminution of the phospholipids/proteins rate of 22%. 2. A reduction of sphingomyelin "in vivo" of 27.66% and "in vitro" of 16.82%. 3. An increase in phosphatidyl choline "in vivo" of 12.24% and "in vitro" 10.28%. The possible effects that these changes might have on the platelet function are evaluated.
