Abstract
Summary
Lipids were measured in the livers and sera of rats that had received phenobarbital injections for 3 days and 5 days. The same lipid patterns including free cholesterol, cholesterol esters, phospholipids, triglyceride and fatty acids were determined in the livers and sera of rats 3 days and 5 days following withdrawal of the drug. Liver lipids increased with time while the rats were injected with phenobarbital and decreased toward normal levels once the drug was withdrawn. During phenobarbital administration as well as during withdrawal the serum lipid levels did not change. These results suggest that decreased lipid transport and enhanced lipid mobilization may not play major roles in the induction of the phenobarbital fatty liver.
