[Effect of thymalin on the development of experimental hyperlipidemia and atherosclerosis].

Thymalin, which is a polypeptide preparation from thymus, exhibited hypolipidemic and antiatherosclerotic actions in rabbits maintained on a cholesterol-containing diet during three months. At the same time, thymalin caused favourable effect on the functional activity of lymphocytes impaired in hyperlipidemic animals, i.e. it normalized the T-suppressor activity and sensitivity to atherogenic lipoproteins.
