Effect of Dihydrocholesterol and β-Sitosterol on Cholesterol Atherosclerosis in Rabbits
While dihydrocholesterol lowered total plasma cholesterol in the rabbit, it did not promote the regression of either the aorta lipid fractions or plaque areas in atherosclerotic animals. A comparative study of the toxicities of β-sitosterol and dihydrocholesterol disclosed that dihydrocholesterol, fed for a 7 month period, resulted in aorta plaque formation and caused the development of liver cirrhosis. On the other hand, β-sitosterol produced no toxic effects.
