alpha tocopherol/infarction

BACKGROUND In vitro, animal and epidemiological studies suggest that lipoprotein oxidation may play an important role in atherosclerosis. Antioxidants may protect against lipoprotein oxidation and in that way inhibit atherosclerosis and its clinical sequelae. To investigate this possibility, we

OBJECTIVE We investigated whether dietary supplementation with the antioxidant vitamin alpha-tocopherol (500 mg daily) might reduce lethal ventricular arrhythmias and infarct size. BACKGROUND Previous studies suggested that dietary supplementation with alpha-tocopherol may be associated with a

The alpha-tocopherol analogue 3,4-dihydro-6-hydroxy-N,N,N,2,5,7,8- heptamethyl-2H-1-benzopyran-2-ethanaminium 4-methylbenzenesulfonate (1a, MDL 73404) and its O-acetate 1b (MDL 74270) were synthesized. Compound 1a was found to be hydrophilic (log P = -0.60) and to prevent lipid autoxidation in rat

A course-wise administration of sodium selenate (30 gamma/kg), alpha-tocopherol (50 mg/kg) and of their combination in the same doses brings down the catecholamines content in the heart and suprarenals in the acute period of developing myocardial infarction (2nd day) with its subsequent

Thirty patients of acute myocardial infarction proven by electrocardiography (ECG) and enzymes were included in the study. All of them received streptokinase. A single lead showing the largest ST elevation, a proportional value for the shift in ST segment > or = 0.5 was taken as criteria for

The present study was designed to evaluate the effects of pretreatment with antioxidants on free radical mediated reprefusion injury. Five dogs were fed with alpha-tocopherol (1000 IU/kg, bw) for ten days prior to 90 min of left anterior descending coronary artery occlusion followed by 4 hours of

Observation of groups of patients receiving traditional treatment and alpha-tocopherol indicates that inclusion of this agent in the treatment of patients suffering of myocardial infarction produced a favourable effect on normalization of the reduced stroke volume of the heart and increased

A new non-injection method was used to study the quantitative values characterizing the condition of the microcirculatory channel of the peri-infarct zones of rat myocardium without treatment and in treatment with nitroglycerin, alpha-tocopherol, and sodium nucleinate. In combined administration of

It is shown that combined administrations of alpha-tocopherol and sodium nucleinate lead to normalization of qualitative and quantitative content of phospholipids in the myocardium of rabbits under conditions of an experimental myocardial infarction. The changes obtained are accompanied by a

The effect of alpha-tocopherol pretreatment (6 mg/100 g body wt/day, orally for a period of 90 days) on mitochondrial electron transport in myocardial infarction induced by isoproterenol (20 mg/100 g body wt, subcutaneously for two days) was studied in rats. A significant decrease was observed in

BACKGROUND Epidemiological data suggest that the intake of antioxidants such as alpha-tocopherol (vitamin E) and beta-carotene has an inverse correlation with the incidence of coronary heart disease. The results from clinical trials of antioxidant supplementation in people with known coronary heart

The inhibitory effect of a phosphate diester of alpha-tocopherol and ascorbic acid (EPC-K1) was examined in myocardial infarction induced in rats, in comparison with a selective 5-lipoxygenase inhibitor, AA-861. EPC-K1 significantly reduced the infarct size at 24 and 48 h after ligation, whereas

Mitochondrial dysfunction plays an important role in the pathology of myocardial infarction. We evaluated the combined protective effects of quercetin and α-tocopherol on mitochondrial damage and myocardial infarct size in isoproterenol-induced myocardia- infarcted rats. Rats were pretreated with

The effect of alpha-tocopherol (6 mg/100 g body wt, orally, daily for 90 days) pretreatment in isoproterenol (20 mg/100 g body wt, subcutaneously, twice at an interval of two days at the end of the alpha-tocopherol pretreatment) induced myocardial infarction was studied in rats. Isoproterenol

BACKGROUND We demonstrate the effect of Aegle marmelos leaf extract (AMLEt) and alpha-tocopherol on plasma lipids, lipid peroxides and marker enzymes in rats with isoproterenol (ISO)-induced myocardial infarction. METHODS Rats were pre-treated orally for 35 days with different doses of an aqueous
