title: The effect of amino acid derivative of clofibric acid (WKLB-5), and theophylline monoester of nicotinic acid (ME1) on the development of experimental atherosclerosis in rabbits.
abstract: In order to determine the efficacy of new compounds--an amino acid derivative of clofibric acid (WKLB-5), and a theophylline monoester of nicotinic acid (ME1)--a high fat diet (HFD) was applied to rabbits for 3 months, with or without the above mentioned compounds. The HFO included coconut oil, cholesterol and cholic acid. A substantial hypolipemic activity of those compounds was demonstrated; however, the studied lipid fractions did not undergo normalization, except FFA whose level after ME1 administration was distinctly lower than in control animals. Sudanophilic changes were found on 83% of surface of the interior membrane of aorta in rabbits kept on the HFD only, on 35% of surface--in rabbits treated with the HFD + WKLB-5, and on 75% of surface--in rabbits treated with the HFD + ME1. Thus in those animals no parallelism between the hypolipemic and antiatherosclerotic activities was observed.
