The role of volume expansion,of prostaglandins and catecholamines in the development of acute renal failure

Summary A single injection either of isotonic or hypertonic saline solutions protected rats against acute renal failure (ARF) induced with glycerol. This protection was accompanied by increased urinary prostaglandin E (PGE) concentration. On the contrary, a single s.c. injection either of hypotonic saline or isotonic glucose solution, which did not increase urinary PGE concentration, or depletion of the endogenous catecholamines, using reserpine, did not protect the animals against acute renal failure.The authors wish to thank Miss Sylvie Bompis and Miss Ermione-Loukia Ghikas for their technical assistance and Mr Richard Irvine B.A. for his help with the English.
