Résumé:
The objective of our work is to evaluate the effects of Enrichment in the PUFA of the
standard regime and the regime by the extract of Phoenix dactylifera seeds on the live weight
and on a few biochemical parameters (total cholesterol, triglycerides, HDL-C, LDL-C, AST
and ALT) and markers of inflammation; the CRP. In case of excess, hypercholesterolemia,
considered as an independent risk factor for atherosclerosis, can cause a lot of molecular
alterations and cellular. Mice Mus musculus, had received the standard regime or the regime
enriched or not by the extract of Phoenix dactylifera seeds during 18 days. Our results show
that the regime hypercholestérolémiant induces hyperphagia and obesity in mice under
hypercholestérolémiant regime compared to control mice. After oral administration of the
high dose of cholesterol, the degradation of this last product an excess of cholesterol in the
blood plasma, which is in turn cause an increase very highly significant of the AST, ALT and
the CRP but not significant for the TG, HDL and LDL. However, mice treated by cholesterol
with extract of Phoenix dactylifera seeds have shown a significant decrease of the AST, ALT,
cholesterol, TG, LDL and the CRP but not significant for the HDL. Therefore, the oil of
Phoenix dactylifera seeds has beneficial effects on the redox status and presents a nutritional
interest. The results obtained in this study show that the extract of Phoenix dactylifera seeds
can be considered as a natural source to prevent and treat cardiovascular diseases
