Megjegyzések:	Fenugreek is a common herb possessing several bioactive components includingdiosgenin. Here, dietary fenugreek seed flour and diosgenin were evaluated on a model ofendothelium-dependent vasorelaxation by abdominal aortas isolated from rats receiving high-fat,high-sugar diet (HFHSD). 60 male Wistar rats were randomized into six groups: (i) negative controlgetting conventional rat feed regimen; (ii) positive control receiving HFHSD; (iii) a test group fed2 g/kg bw/day fenugreek seed flour (containing 10 mg/kg bw/day diosgenin) + HFHSD; (iv) threetest groups fed 1, 10 and 50 mg/kg bw/day diosgenin + HFHSD. Alimentary treatments werecarried out for six weeks. The abdominal aortas were isolated, and 2 mm wide rings were sectionedoff and mounted at a resting tension of 10 mN in organ baths containing Krebs solution (36 ?C)exposed to 95% O2 and 5% CO2. After 60-min incubation, a norepinephrine concentration-response(E/c) curve was generated to determine their half-maximal effective concentration (EC50) value.After 60-min wash-out, a pre-contraction with norepinephrine EC50 was made, followed by anacetylcholine E/c curve. Plasma glutathione levels, glutathione-handling enzyme activities and bloodantioxidant capacities were also determined. HFHSD significantly decreased the dilatory response toacetylcholine and increased plasma glutathione levels and these effects were significantly reversed byfenugreek seed flour, 10 and 50 mg/kg bw/day diosgenin. Both fenugreek and diosgenin treatmentsprevent HFHSD-induced endothelial dysfunction and redox changes. As fenugreek treatmentwas more effective at lower acetylcholine concentrations than diosgenin treatments, components offenugreek other than diosgenin may contribute to the beneficial effects of dietary fenugreek seed flour.
