Abstract
The ceroid pigment observed in aged animals and man is produced in vitamin E deficient animals too. When adequate protein was given to rats together with fish oils, unoxidized fish oil did not show any discoloration in uterus whereas oxidized one produced ceroid pigment significantly. On protein deficient diet the effect of vitamin E deficiency caused by feeding fish oil was aggrevated and the discoloration was seen even in rats fed unoxidized fish oil.
Two mg of dl-α tocopherol has partially prevented discoloration caused by fish oil, but 20mg of it was necessary to prevent the production of ceroid pigment completely. In contrast to fish oil, soybean oil, given at the same level did not result any discoloration of body fat.
