This paper deals with the effect of tocopherol on serum iron content in experimental atherosclerosis (ATS). Having in mind the importance of iron as a potent catalyst in some oxidative reactions, we examined the iron content in serum of Chinchilla rabbits with ATS induced by a hypercholesterolemic diet. Serum iron content was quantified by atomic absorption spectrophotometry. For this study six groups of rabbits were used: C – control group fed the usual diet for this species (n=10), O – control group fed an oil-containing diet (n=10), Ch – experimental group fed a hypercholesterolemic diet (n=10), T – experimental group received tocopherol intramuscularly (n=10), ChT – experimental group treated with cholesterol and tocopherol (n=11), and OT – experimental group which received oil and tocopherol (n=11). After two-months of treatment decrease of iron content was registrated in serum of T and OT group (p<0.05; p<0.01 respectively) compared to both control groups. In comparison with Ch group serum iron content was highly significantly (p<0.01) decreased in OT group and significantly (p<0.05) decreased in T group. Our findings indicate that tocopherol has an influence on serum iron content in rabbits suffering from ATS induced by a hypercholesterolemic diet.
