We have determined the incorporation of retinol-C14 into liver mitochondrial membranes and blood cell stroma in albino male Wistar strain rats, fed with a vitamin A deficient diet for 30, 60 and 90 days. At the end of the vitamin A deficient period, rats were kept fasting for 24 hours and then administered orally retinol-C14 (1,25 microC). They were divided into groups and killed after 3 hours, 3, 6, 12 days from the administration of retinol-C14. The incorporation is very high in one-month deficient rats, it decreases as the experimental period and the intervals after the administration of retinol-C14 grow longer.
