Sixty-five squirrel monkeys (Saimiri sciurea) were studied for a year. During the last 9 months, spontaneously occurring atherosclerosis was accelerated by feeding a diet containing cholesterol and butter. Of six separate groups of animals, three groups were examined for the effects of acid mucopolysaccharides on the process of atherosclerosis. Monkeys treated with parenteral chondroitin sulfat...

Gastrointestinal parasitic infections are a major constraint to small ruminant productivity in the tropics and subtropics, including Tanzania. This significantly reduces the economy and food supply to small farmers and their families. Earlier studies at the University of Nottingham (see for example Butter et al., 2000) have shown that feeding the extracted tannin from Quebracho (used in the lea...
