FIGURE 10

Isometric tension recording in an isolated blood vessel. An arterial ring is studied in an organ chamber filled with thermostated and oxygenated physiological salt solution. The inset shows recording traces of an experiment reproducing the seminal observation first made by Furchgott and Zawadzki in 1980 [496]. Isolated rings of canine coronary artery with and without endothelium are contracted with prostaglandin F (PGF). The addition of acetylcholine produces a concentration-dependent relaxation only in the ring with a preserved endothelial lining.
