[The role of platelets in the protective effect of a combination of vitamins A, E, C and P in thrombinemia].
White rat experiments have shown that combination of vitamins A, E, C and P diminishes thrombin-induced thrombocytopenia and low platelet aggregation. This is explained by limited activation of free radical processes initiated by thrombin in plasma, red cells and platelets. It was found that thrombin ability to activate lipid peroxidation is not related to coagulatory transformation of fibrinogen, but is rather due to a direct contact of the enzyme with platelets. A protective effect of vitamins-antioxidants in thrombinemia is likely to rest on their ability to restrict activation of free radical oxidation in platelets.
