Abstract

The metabolism of cholecalciferol (vitamin D3) was studied in cirrhotic and in control rats that were either depleted of or supplemented with vitamin D3. The vitamin was supplemented by s.c. injections of radiolabeled cholecalciferol at doses which meat the daily nutritional requirements of rats. Excretion of vitamin D3 metabolites in the feces of the cirrhotic rats was greater than that in the control rats. Fecal excretion consisted mainly of vitamin D3 ester the unchanged vitamin D3 and 25-hydroxyvitamin D3. It is suggested that one of the causes for vitamin D3 depletion in cirrhosis of the liver is fecal loss.
