Feeding large doses (30,000 IU/100 g body wt per day) of vitamin A to young rats for 2 days produced fatty liver, caused a stimulation of oxidation and esterification of [1-14C]palmitate by liver slices, and increased the activity of hepatic palmitoyl-CoA synthetase. Under similar conditions,
1. The total lipid, phospholipid, total and free fatty acid, free and esterified cholesterol contents of the long bones of normal, hypervitaminotic A, D and A plus D rats were determined. 2. Toxic amounts of vitamin A decreased the total fatty content, whereas toxic amounts of vitamin D increased
