[Chronic lathyrism, prolonged hyperlipidic diet, and atheroma in the rat].

Deep, constant, extensive atherosclerosis can be experimentally induced on rats that are atheroresistant. Two main factors are involved in this experimentation; parietal alteration following chronic intoxication with BAPN (9 weeks) and a metabolic factor with hyperlipidic diet, but this metabolic damage should be sustained for a long time (40 weeks).
