Jaap Homan van der Heyde a.o.: Effect of dietary fish oil on renal function and rejection in cyclosporine-treated recipients of renal transplants. New England J. Med. 329 (1993), 769-773. The daily administration of 6 g of fish oil during the first postoperative year has a beneficial effect on renal hemodynamics and blood pressure in renal transplant recipients treated with cyclosporine. Although the fish-oil group had significantly fewer rejection episodes than the control group, graft survival at one year was not significantly better in the fish-oil group.
