title: The role of the pineal gland in the lipid metabolism.
abstract: The study contains the data gathered with time with regard to the involvment of the pineal gland in the lipid metabolism. Thus, it has been demonstrated that administration of the pineal extract lowers serum, hepatic, adrenal and testicular cholesterol of rat and that pinealectomy causes reverse effects. Administration of melatonin did not cause significant alterations. The same pineal extract reduced cholesterolemia, biliary cholesterol and serum phospholipids in rabbits whereas the absence of the pineal gland caused an increase in cholesterolemia, total lipids and FFA. Pineal treatment reduced the major lipid components of the blood and aorta in experimental atheromatosis induced in rabbits. The results presented in this paper demonstrate the inhibiting role played by the pineal gland in the lipid metabolism.
