Is the vasodepressor function of the kidney : prostaglandin E2 the principal vasodepressor lipid of the renal medulla?
Prostaglandins are excluded as the blood pressure-lowering active principle of a total lipid kidney medulla extract. The vasodepressor principle is contained in the kidney medulla, but not in the cortex. It can be separated from endogenous emulsifying substances, is chromatographically stable, and is amenable to purification and chemical characterization.
Prevalence of positive microbiologic results and subsequent infections do not appear to be increased with the method of donor handling used for newer techniques for keratoplasty.
