Abstract

This study was carried out to examine the relaxational response to the water extract of Sobokchuko-tang (SCT) in rat thoracic aorta. Segments of thoracic aorta obtained from rats immediately after delivery were mounted in organ baths superfused on a polygraph. It was found that the thoracic aorta segments responded to the SCT with dose-dependent vasorelaxation. At $10^{-7}M$ phenylephrine-induced contraction, the contractile response of thoracic aortic rings were inhibited by 99.2%. 75.3%. 42.4% and 35.8% after addition of the respective concentration (1O. 30. 100. $300{\mu}g$/ml) of SCT. This vasorelaxation of rat thoracic aorta was endothelium-dependent. The action mechanisms of vasorelaxation are thought to be concerned with the role of NO. cAMP and cyclooxygenase. but not with cGMP.
