A. Recherches anatomopathologiques chez le rat ingérant différentes doses d'huile d'arachide ou d'huile de colza à faible teneur en acide érucique (Huile de colza Primor). 6a. Etude structurale et ultrastructurale du myocarde

Summary. A. Anatomo-pathological research on rats ingesting different doses of peanut oil or of low-erucic acid rapeseed oil (Primor rapeseed oil). 6a. Structure and fine structure of the myocardium. Structural and ultrastructural observations were carried out on the myocardium of Wistar rats receiving increasing amounts (5, 10, 15 p. 100 in weight) of either peanut oil or Primor rapeseed oil in the diet. After 6 months of diet, myocardial changes, although depending on dietary oil content, were more extensive in the rats fed Primor rapeseed oil than in those fed the peanut oil. After 1 year of the 5 p. 100 diet containing either peanut oil or Primor rapeseed oil, myocardial modifications were of the same order and type. These changes were more extensive than those observed after 6 months of diet. Les animaux différentes
