The present study was designed to investigate the effect of dexamethasone treatment for 2 weeks (2.5 mg/kg/week, subcutaneously) on the level of unesterified fatty acids, particularly arachidonic acid, in the renal medulla of rats, and to relate the observed effect to changes in the tissue concentration and the fatty acid composition of renal medulla phospholipids and triglycerides. Dexamethasone treatment caused an increase in the renal inner medulla level of unesterified fatty acids, including arachidonic acid, that was associated with a reduction of triglycerides and of arachidonic acid esterified into triglycerides, and with an increase in the rate of fatty acids esterification into triglycerides. In contrast, dexamethasone treatment did not affect the renal medulla concentration of phospholipids, the arachidonic acid content of renal medulla phospholipids, or the rate of esterification of fatty acids into renal medulla phospholipids. In the face of increased fatty acid esterification into triglycerides, the finding of reduced triglyceride levels in the renal medulla of dexamethasone-treated rats suggests excessive triglyceride breakdown. If so, fatty acids including arachidonic acid liberated from triglycerides may contribute to elevation of unesterified fatty acid levels in the renal medulla during dexamethasone treatment. The increased level of free arachidonic acid in the renal medulla of dexamethasone-treated rats may explain in part the reported effect of this steroid in increasing urinary prostaglandins.
