Résumé
Le son représente l’enveloppe externe qui est une partie importante des grains du seigle, du fait de son intérêt nutritionnel et thérapeutique. L’étude portée sur la composition chimique montre que le son est une source riche en fibres avec un taux estimé à 39%. Ce travail porte sur la recherche de l’effet hypoglycémiant, hypolipidémiant et l’évaluation du pouvoir antioxydant après avoir administré un régime expérimental à base de son de seigle aux rats normaux et d’autres rendus diabétiques par la streptozotocine (STZ) pendant un mois d’expérimentation. Cet effet est également analysé chez les rats normaux et diabétiques soumis à un régime témoin. D’autres paramètres le poids corporel, le poids de fèces et la teneur en protéines totales, ont été évalués. Les résultats ont montré un effet hypoglycémiant net. De même on a noté l’influence du son de seigle (riche en fibres) sur la diminution de la concentration du cholestérol et des triglycérides. L’évaluation du statut antioxydant a montré des teneurs élevées des vitamines E et C et de l’ORAC chez nos lots expérimentaux et une diminution des marqueurs de la peroxydation lipidique et protéique.
Abstract
The bran of secale represents the external envelope, an important part of the grains of rye because of its nutritional and therapeutic interest. The study carried on the chemical composition of the bran of rye, watch which the bran is a source rich in fibers with an important rate estimated at 39%. This work concerns the research of the hypoglycemia effect, correct lipidic metabolic disorders and the evaluation of the antioxidant capacity, after having managed an experimental mode containing bran of rye to the normal rats and others returned diabetics during 1 month of experimentation. This effect is also analyzed in the normal rats and diabetics subjected to a pilot mode. Other parameters the body weight, the weight of deposit and the content of total proteins were evaluated. The research of the hypoglycemia effect of the bran of rye, led us to results showing an hypoglycemia effect. The same our results show as the influence of rye fibers on the disorders of the lipidic metabolism is significant in the reduction in the concentration of cholesterol and triglycerides. The evaluation of the antioxidant statute showed high contents of the vitamins E, C and total antioxidant capacity (ORAC) at our experimental rats and a reduction of a markers of lipidic and proteinic oxidation.
