Electronic Theses and Dissertations

The effect of wild blueberries on major endothelium-dependent vasodilation pathways and arterial blood pressure (BP) was examined in the young adult Spontaneously Hypertensive rat (SHR), used as a model of endothelial dysfunction, and the Wistar Kyoto (WK) rat, with functional endothelium, used as the control. Male SHR and WK rats were fed a control (SHR-C and WK-C), or a wild blueberry-enriched (SHR-B and WK-B) diet for nine weeks.
