Prostaglandin E2 (PGE2) and 6 keto-PGF1 alpha, the stable metabolite of prostacyclin (PGI2), have been measured in the effluent of perfused rat mesenteric arteries by the use of a sensitive and specific radioimmunoassay (RIA) method. The PGE2 and 6 keto-PGF1 alpha were continuously released by the unstimulated mesenteric artery over a period of 145 min. After 100 min of perfusion the release of PGE2 and 6 keto-PGF1 alpha was 45.1 +/- 8.4 pg/min and 254 +/- 75 pg/min respectively, which is in accord with the general belief that PGI2 is the major PG synthesized by arterial tissue. Angiotensin II (AII) (5 ng/ml) induced an increase of PGE2 and 6 keto-PGF1 alpha release without changing the perfusion pressure. The effect of norepinephrine (NE) injections on release of PGs depended on the duration of the stabilization period. The changes of perfusion pressure induced by NE were not related to changes in release of PGs. Thus, it seems that the increase of PG release induced by AII and NE was due to a direct effect of the drugs on the vascular wall. This may represent an important modulating mechanism in the regulation of vascular tone.
