We determined serum levels of ascorbic acid, betacarotene, retinol and alpha tocopherol and lipid peroxidation (as estimated by thiobarbituric acid reacting substances (TBARS) generation) in 24 multiple sclerosis (MS) patients and 24 healthy sex- and age-matched person as control. The levels of four antioxidant vitamins were significantly lower in MS patients compared to controls (p < 0.05). TBARS levels were significantly higher in the patients of MS compared to the controls (p = 0.001). In MS patients, the levels of beta-carotene, alpha tocopherol and ascorbic acid correlated significantly with each other (r2 = 0.689 - 0.779). It appeared that there was inverse correlation between the serum levels of ascorbic acid or beta-carotene, but not of alpha tocopherol or retinol, and TBARS levels in MS. The present study indicates that antioxidant vitamins (alpha tocopherol, beta-carotene, retinol and ascorbic acid) are decreased in sera of MS patients during an attack, and that this decrease may well be dependent on the increased oxidative burden as reflected by lipid peroxidation products. The role of antioxidant vitamin supplementation in prevention and/or treatment of MS remains to be explored.
BackgroundIn this study discussed the primary and regulatory roles of fatty acids, and investigated the affects of fatty acids on metabolic programming.MethodsReview of the literature was carried out on three electronic databases to assess the roles of fatty acids in metabolic programming. All abstracts and full-text articles were examined, and the most relevant articles were selected for screening and inclusion in this review.ResultsThe mother’s nutritional environment during fetal period has important effects on long term health. Fatty acids play a primary role in growth and development. Alterations in fatty acid intake in the fetal period may increase the risk of obesity and metabolic disorders in later life. Maternal fatty acid intakes during pregnancy and lactation are passed to the fetus and the newborn via the placenta and breast milk, respectively. Imbalances in fatty acid intake during the fetal period change the fatty acid composition of membrane phospholipids, which can cause structural and functional problems in cells. Additionally, the metabolic and neuroendocrine environments of the fetus and the newborn play key roles in the regulation of energy balance.ConclusionsImbalances in fatty acid intake during pregnancy and lactation may result in permanent changes in appetite control, neuroendocrine function and energy metabolism in the fetus, leading to metabolic programming. Further studies are needed to determine the role of fatty acid intake in metabolic programming.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
