Level was measured retinol income after 7 and 30 days of administration of megadoses of vitamin A, retinol concentration was determined by High Pressure Liquid Chroma-tography (HPLC) in blood plasma. Results: the first sample is serum retinol below 20 mg / dL in both groups, this value increases to more than 30 g / dl in the second sample (7 days) and is held in the third sample (months). No clinical signs were observed deficiency in eutrophic children, whereas in all malnourished children were found clinical signs of malnutrition and vitamin deficiency as 50% conjunctival and corneal xerosis, decreased growth, 60%, bacterial infection, 100%, skin lesions, 40% and changes in the hair 60%.
