Abstract: Objective:This study aimed to investigate the effects of
Methods:In this study, 0.1% DMG was supplemented in 20% casein diets that were either folate-sufficient (20C) or folate-deficient (20CFD). Blood and liver of rats were subjected to assays of Hcy and its metabolites. Hcy and its related metabolite concentrations were determined using a liquid chromatographic system.
Results:Folate deprivation significantly increased pHcy concentration in rats fed 20C diet (from 14.19 ± 0.39 μmol/L to 28.49 ± 0.50 μmol/L;
Conclusion:DMG supplementation exhibited hypohomocysteinemic effects under folate-sufficient conditions. By contrast, the combination of folate deficiency and DMG supplementation has deleterious effect on pHcy concentration.
