ethyl oleate/necrosis

BACKGROUND Fatty acid ethyl esters (FAEE), nonoxidative products of ethanol metabolism, are formed by the esterification of fatty acids and ethanol. Alcoholic subjects have high levels of FAEE in the circulation as well as in organs and tissues, especially those most often damaged by ethanol abuse.

The aim of this study was to improve the analgesic effect of evodiamine and rutaecarpine, using a microemulsion-based hydrogel (ME-Gel) as the transdermal co-delivery vehicle, and to assess hyaluronic acid as a hydrogel matrix for microemulsion entrapment. A microemulsion was formulated with ethyl
