The pressor and tachycardiac effects and increases in serum catecholamine levels caused by NS-3 were longer lasting, but not more potent than those caused by TRH. 3. NS-3 did not change the blood pressure, heart rate, or the serum catecholamine levels in either pithed or hexamethonium-pretreated rats.
