Abstract
Summary
Levels of total cholesterol in plasma of rats fed several variations of a basal infarct-producing diet containing 40% butter, butter-oil or lard were higher than in rats of other groups fed vegetable fat (corn oil or Crisco). Levels of rats in group offered a diet not containing exogenous cholesterol were far lower than those of the control group. A significantly high level was observed when the amount of salt mix in the diet was increased 3-fold to 12%. In a group of 30 rats fed the basal diet, cholesterol in plasma of those that developed infarcts rose neither more rapidly nor to significantly higher levels than did cholesterol in plasma of rats in the same group that did not develop infarcts within experimental period of 4 months.
