Protective effect of menhaden oil on renal necrosis occurring in weanling rats fed a methyl-deficient diet

Weanling rats fed a lipotropic-deficient diet (LDD) may develop acute renal failure with morphological features that vary from focal tubular necrosis to widespread cortical necrosis and eventually reparative changes. The type of lipid in the diet influences the development of renal necrosis. The aim of this work was to study the effect of dietary menhaden oil on the development of acute renal failure induced in weanling rats fed a methyl-deficient diet. Experiment I: 40 weanling Sprague-Dawley male rats were allotted to 4 different groups and fed as follows: group 1, LDD with hydrogenated vegetable oil and corn oil as lipids; group 2, LDD with menhaden oil as lipid; group 3 and 4, similar t…
