A particularly useful method is to measure F2-like prostanoid derivatives of arachidonic acid, termed F2-isoprostanes (IsoP) (32). The detection of RSNO has often employed the Saville reaction, which involves the displacement of the nitrosonium ion (NO+) by mercury salts. The resulting nitrite or NO generated from the spontaneous decomposition of NO+ is detected by methods such as chemiluminescence or HPLC. Other techniques for the detection of RSNO employ colorimetric methods such as the Griess reaction to measure the nitrite formed from the treatment of RSNO with mercuric chloride.
5 mmHg/m (52). A different pO2 and ROS/RNS Measurements in the Microcirculation in Hypoxia 35 approach has been taken by Intaglietta et al. and Shibata et al. , the correspondence between the longitudinal oxygen gradients correspondence with the radial rate of oxygen exit. This approach, combined with a demonstrated decreased rate of oxygen consumption show that the arteriolar wall is a significant consumer of oxygen, as evidenced by the larger that diffusion limited oxygen gradient in this district.
It is well established and functionally reasonable that the endothelium regulates the release of vasoactive substances in response to O2 and NO availability. However, the remaining critical issues depend on the importance of O2 consumption by the method and the magnitude of the oxygen gradients at the vessel wall. Golub et al. (51) have provided experimental evidence on the lack of significant gradients across the arteriolar wall, thus concluding that this tissue compartment is essentially transparent to the passage of oxygen, providing limited diffusional resistance and oxygen consumption.
