[Effect of progesterone on rat plasma and liver lipid levels (author's transl)].

The effect of progesterone upon several lipidic parameters on rat liver and plasma was studied. Progesterone administration led to a significant increase in the hepatic triacylglyceride and cholesterol esterified levels and to a decrease in the phospholipid content. After progesterone treatment decreases in plasma total lipids, phospholipids, cholesterol and cholesterol esterified were observed, whereas plasma triacylglyceride and free fatty acid levels increased. The hormonal treatment altered the lipoprotein pattern, which significantly reduced the beta-lipoprotein fraction.
