Ethyl dihomo-γ-linolenicacid ethyl ester (ethyl DGLA), an ω-6 fatty acid intermediate ester form, elevates prostaglandin E1(PGE1) and PGE2 secretion in rabbit renal papilla when administered dietarily at a dosage of 1 g kg per day for 25 days. Additionally, this dosage of ethyl DGLA increases triglyceride levels and enhances the proportion of 20:3ω6 and 20:4ω6 phospholipids in the renal medulla of rabbits. Ethyl DGLA formulations have been employed in managing eczema and inflammatory disorders.
