pubmed-article:500824 | pubmed:abstractText | The effect of two prostaglandin synthesis inhibitors, indomethacin and meclofenamate, on angiotensin II (AII)- and III (AIII)-induced aldosterone release was studied in normal and sodium-depleted conscious rats and in adrenal capsular cell suspensions obtained from normal rats. In normal rats, in vivo AII and AIII were equipotent in causing dose-related increases in serum aldosterone concentrations. Indomethacin decreased the basal serum aldosterone levels by 50% and serum renin levels by 43%. In addition, the steroidogenic effects of AII and AIII were reduced by 45 and 63% with 3 mg/kg of indomethacin and 63 and 73% with 10 mg/kg, respectively. In contrast, meclofenamate failed to alter basal serum levels of aldosterone or AII-stimulated aldosterone release but inhibited serum renin levels by 27% and the aldosterone-stimulating effect of AIII by 99%. Indomethacin (3 mg/kg) and meclofenamate (2 mg/kg) inhibited urinary prostaglandin (PG)E(2) and PGF(2alpha) excretion by 63 and 52% and 37 and 31%, respectively. Both inhibitors significantly decreased the adrenal capsular PGE(2) and PGF(2alpha) content and the conversion of [(14)C]arachidonate to [(14)C]PGE(2) and [(14)C]PGF(2alpha). In sodium-depleted rats, indomethacin produced similar effects reducing the control serum aldosterone levels by 29%, AII-stimulated aldosterone by 47%, and completely suppressing the aldosterone response to AIII without altering serum renin activity. In adrenal cell suspensions, similar results were observed with indomethacin inhibiting basal and AII- and AIII-stimulated aldosterone release by 29, 81, and 93%, respectively. Meclofenamate failed to alter basal and AII-stimulated aldosterone release but inhibited that stimulated by AIII by 86%. The present findings suggest that prostaglandins modulate the effects of the renin-angiotensin system by stimulating the release of renin from the kidney and augmenting the steroidogenic effects of AII and AIII in the adrenal cortex. | lld:pubmed |
