Abstract
To clarify the influence of iron deficiency on mineral status, the following two synthetic diets were fed to male Wistar rats: a control diet containing 128 μg iron/g, and an iron-deficient diet containing 5.9 μg iron/g. The rats fed the iron-deficient diet showed pale red conjunctiva and less reactiveness than the rats fed the control diet. The hemoglobin concentration and hematocrit of the rats fed the irondeficient diet were markedly less than the rats fed the control diet. The changes of mineral concentrations observed in tissues of the rats fed the iron-deficient diet, as compared with the rats fed the control diet, are summarized as follows:
-
• Iron concentrations in blood, brain, lung, heart, liver, spleen, kidney, testis, femoral muscle, and tibia decreased;
-
• Calcium concentrations in blood and liver increased; calcium concentration in lung decreased;
-
• Magnesium concentration in blood increased;
-
• Copper concentrations in blood, liver, spleen and tibia increased; copper concentration in femoral muscle decreased;
-
• Zinc concentration in blood decreased;
-
• Manganese concentrations in brain, heart, kidney, testis, femoral muscle and tibia increased.
These results suggest that iron deficiency affects mineral status (iron, calcium, magnesium, copper, zinc, and manganese) in rats.
