Abstract:
Chicks were overfed a basic diet supplemented isocalorically by soyabean oil or glucose 1, 2 and 10 days after 1 day of starvation. Carcass lipids resumed the prestarvation level 1 and 2 days after overfeeding with oil or glucose, respectively. After 10 days, an equal amount of lipid, mainly triglycerides, accumulated in the carcasses of both supplement groups. In the liver a transient accumulation of lipid was noticed in the oil-supplemented groups while a continuous increase was found in the glucose-supplemented ones. Hyperlipemia, due essentially to very low density lipoprotein (VLDL), was concomitant to liver lipid concentration. After 1 day, oil overfeeding raised plasma VLDL 6-fold, while the same level of VLDL was obtained within 2 days with glucose supplement. After 10 days, hyperlipemia was reduced in the oil-supplemented group, while it increased in the glucose-supplemented one. The fatty acid fluctuation caused by the treatments in liver lipids and plasma VLDL were grossly similar: The level of linoleic acid was reduced by glucose and increased by oil supplementation; the linoleic acid increase in VLDL proceeded that of liver lipids in the oil-supplemented groups. The results indicate a delayed transport of newly synthesized hepatic lipids in glucose-supplemented animals. © 1979 S. Karger AG, Basel.
