Absorption of retinol and retinyl esters via lymph and the portal vein in the rat

, : Absorption of retinol and retinyl esters via lymph and the portal vein in the rat. Canadian Journal of Physiology and Pharmacology 50(8): 753-760

Wistar rats, normally fed or depleted of vitamin A until signs of deficiency had begun to appear, had cannulae inserted in the thoracic duct 24 h before the absorption studies; even for the normally fed rats vitamin A was excluded from the diet for 3 days before and during experiments to prevent dilution of test doses with dietary vitamin. Test doses of retinyl acetate-11,12-3H in unlabelled carrier were given in maize oil.
