Abstract
The effect of intramuscular administration of retinol (100,000 I.U. daily for 13 days) on intestinal lipids of young rats has been studied. The administration of toxic doses of retinol significantly increased the total lipids of intestine as compared with the control. A significant increase in intestinal monoglycerides, and in phosphatidic acid and polyglycerol phosphatide (present in the phospholipid fraction eluted from a silicic acid column with 5% methanolic chloroform) was observed in the hypervitaminotic A rats. There was no significant difference in the daily food consumption and body weight between the hypervitaminotic A and control rats at the time of sacrifice.

Abstract
The effect of administration of retinol (100,000 I.U. daily for 10 days) on the fatty acid composition of brain in rats has been studied. The administration of large doses of retinol to rats did not significantly affect the saturated fatty acids of brain, i.e. C 16:0, C 18:0, C 20:0, C 21:0, C 23:0, and C 24:0 as compared with untreated control. A significant increase in the concentration of brain oleic acid was found in hypervitaminotic A rats (27.9 ± 1.74%) as compared with the untreated controls (22.0 ± 2.70%). The concentrations of polyunsaturated fatty acids, i.e. C 20:4 and 22:6 were significantly reduced in hypervitaminotic A rats as compared with untreated controls.
