Influence of zinc on cardiac and serum biochemical parameters in rabbits.

The pattern of lipid profiles and organic constituents of cardiac and serum tissues of rabbits were studied on treatment with cholesterol, zinc and zinc + cholesterol. Total carbohydrate and total protein levels were decreased with elevated lipid levels in cholesterol fed rabbits. However, the zinc and cholesterol + zinc fed rabbits showed decreased lipid fractions in cardiac and serum tissues leading to reduced atherosclerotic process in rabbits. These results suggest that the zinc is acting as a hypolipidaemic and anti atherogenic agent in experimental rabbits.
