[Effects of high dietary zinc on mice (II)--Influence on growth, blood composition and immune function]

The effects of high-dietary-zinc (HZ, 1.5 g/kg) on growth, blood composition and immune function were studied with a high-dietary-zinc model of mice. By 3 weeks, the body weight and food consumption of mice were significantly lower in HZ group than those in control group. The concentrations of hemoglobin and blood calcium decreased significantly and the platelet and cholesterol levels increased significantly in HZ group. The HZ group showed a spleen swelling and depressed immune function.
