STUDIES ON THE INTERACTION OF ORGANIC ZINC AND HEME IRON IN RATS / 营养学报

ABSTRACT

Forty male weanling rats ( Sprague Dawley strain) were chosen and allotted randomly into four treatments. Diets with various organic zinc and heme iron levels were fed for 35 days respectively. GroupⅠ the basic diet of low zinc and iron. Group Ⅱ adding the enokitake zinc to the basic diet in which the organic zinc content was 60 ppm. Group Ⅲ adding the heme iron to the basic diet in which the heme iron content was 24 ppm. Group Ⅳ adding the enokitake zinc and heme iron to the basic diet in which the organic zinc and heme iron were 60 ppm, 24ppm respectively. At the end, Hb and the content of serum and hepatic iron in the group Ⅲ, Ⅳ were higher significantly than that in the group Ⅰ, Ⅱ.The body weight, serum zinc, hepatic zinc and femur zinc in group Ⅱ, Ⅳ were higher significantly than that in group Ⅰ,Ⅲ. It suggests that there isn't competitive inhibitory interaction between the organic zinc and the heme iron and combined supplementation of them can prevent from zinc and iron deficiency.
