Moringa oleifera Seeds Attenuate Vascular Oxidative and Nitrosative Stresses in Spontaneously Hypertensive Rats

Figure 1

(a) Oxidative stress (red staining by DHE of O₂⁻ in rat aortas from Wistar Kyoto (WKY), SHR untreated (SHR), and SHR treated with MOI (SHR MOI)). Green fluorescence corresponds to autofluorescence of elastin. Below phase-contrast images. Negative control C(−) without DHE. (b) Fluorescence is expressed in arbitrary units (a. u.), WKY (white plot), SHR (black plot), and SHR MOI (grey plot) ( for each group, SHR versus WKY and ^### SHR MOI versus SHR). (c) Circulating levels of free 8-isoprostane expressed in pg/ml of plasma ( for each group, SHR versus WKY and ^# SHR MOI versus SHR).
