Prostaglandin E2 production by renomedullary tissue of DOCA, Goldblatt and spontaneously hypertensive rats

Abstract

The realtionship between in vitro prostaglandin production by renal medullary tissue and hypertension was investigated in three models of hypertensive rat, i.e., DOCA, Goldblatt and SHR. Medullary minces were incubated for 30 minutes. Following incubation tissue PGE2 concentration was quantified using mass fragmentography. Media PGE2 concentrations were quantified using radioimmunoassay. Concentrations of PGE2 in tissue from Goldblatts and SHRs were significantly less than normotensive controls. The concentration of PGE2 in media after incubating SHR tissue was significantly less than normotensives. The data suggest that alterations in PGE2 metabolism are similar in Goldblatt and SHR hypertension.
