Abstract
Bradykinin and angiotensin administered to the isolated perfused rabbit kidney activate 2 sequential processes: a selective release of the prostaglandin [PG] precursor arachidonate with concomitant partial conversion of the arachidonate into PGE2; and activation of a process that leads to decreased release of all fatty acids in the perfusate. There is a time lag of .apprx. 1 min between the initial activation of the arachidonate-specific deacylation reaction that is coupled to PG generation and the subsequent decrease in the release of all fatty acids. This synchronized cycle provides for instant generation of required amounts of PG, and at the same time serves to conserve cellular arachidonate.
