Abstract
Objective
Study the effects of acute and chronic restraint stress on the whole blood concentrations of iron (Fe), zinc (Zn), calcium (Ca), and magnesium (Mg) in mice.
Materials and methods
Single or repeat restraints were applied to mice to induce acute or chronic stress. The levels of elements in whole blood were determined by flame atomic absorption spectrometry.
Results
The levels of Fe, Zn, Ca, and Mg in blood in the acute-stress group were 351, 5.05, 60, and 44 μg/ml, respectively, and those in the corresponding control group were 391, 5.90, 59, and 45 μg/ml, respectively. The levels of blood Fe, Zn, Ca, and Mg in the chronic-tress group were 291, 3.62, 59, and 40 μg/ml, respectively, and those in the corresponding control group were 393, 4.82, 48, and 43 μg/ml, respectively. The levels of Fe and Zn in the blood of both the acute-stress and the chronic-stress groups were significantly lower (P < 0.05) than that in the control groups. The Ca level in whole blood was significantly (P < 0.05) higher in the chronic-stress group than that in the control group.
Conclusion
Acute and chronic restraint stress can cause changes in blood levels of Fe and Zn in mice.
