title: Aortic sudanophilia an zinc-copper ratios in the liver of vervet monkeys fed different types of dietary fibre.
abstract: Vervet monkeys (Cercopithecus aethiops pygerethrus) were fed a semipurified diet containing 40% sucrose, 25% casein, 14% hydrogenated coconut oil and 15% fibre for 6 months. Alfalfa, cellulose, or wheat straw was the source of the fibre. All the diets led to aortic sudanophilia, but the group fed wheat straw had the highest copper level in the liver and the least sudanophilia. The order to severity of the sudanophilia, the ratio of zinc to copper in the fibers, and the ratio of zinc to copper in the liver were: alfalfa-fed group greater than cellulose-fed group greater than wheat straw-fed group. These findings, which may have resulted from the relatively large amount of copper in the wheat straw, are consonant with observations on lipid metabolism in other species.
