the cardiovascular effects of beta-endorphin [ beta-lph- ( 61-91 ) ] were investigated after systemic ( i.v . ) and central ( third ventricle and right lateral ventricle ) administration in urethane-anesthetized rats . beta-endorphin ( 10 and 100 micrograms/kg i.v . or 40 micrograms into the third ventricle or into the lateral ventricle ) in normotensive animals induced a decrease in blood pressure and bradycardia .
