title: Hydrocortisone administration enhances vessel contractility in Koltushi low-, and Koltushi high-avoidance rats.
abstract: The contractility of tail artery rings was investigated in rats psychogenetically selected for rapid (KHA) and slow (KLA) acquisition of an avoidance response in the shuttle box. The vessel contractility was greater in the KHA rats. Hydrocortisone administration enhanced vessel contractility in both strains.
