Vasodilatation of isolated rat coronary arterioles induced by release of extravascular pressure (EVP) in control and after administration of l-NAME (2 × 10−4 M). EVP was increased from 0 to 75 mmHg for 20 and 60 s. Post-EVP dilation is presented as an area that was calculated as the difference between a product of diameter (in μm) and duration (in s) under a specific response curve and a product of the control diameter and the duration of the same response curve. Each bar represents an average of 6 measurements (means ± SE).
