we have investigated the role of prostaglandins ( pg ) in the modulation of adrenergic neuroeffector events by examining the effect of pgi2 and pge2 and their precursor , arachidonic acid , on the decrease in renal blood flow elicited by renal nerve stimulation or by injected norepinephrine in pentobarbital-anesthetized rats , with or without pretreatment with the cyclooxygenase inhibitor , sodium meclofenamate .
