ABSTRACT
Objective:
To study the effects of zinc on transport function of erythrocyte membrane.Methods:
This study was conducted both in vivo and in vitro. In vivo, weanling rats were divided into three groups and fed with different zinc diets (2.2, 28 and 128 mg Zn/kg diet) for four weeks, the transport function of Na +/K + pump, COTS-1, COTS-2, Gardos and RF channels were determined. In vitro, different concentration of zinc (0,5,10,50,100 and 500 ?mol Zn 2+ /L) were added into fresh human blood and the activities of the five transport channels were detected.Results:
Proper zinc could keep the highest activities of Na +/K + pump, COTS-2 and Gardos channel. Too low or too high zinc decreased the transport function of these three channels and the activities of COTS-1 and RF channel were increased with the increase of zinc concentration, indicating the competitive function of these two channels.Conclusion:
Zinc plays an important role in maintaining the transport function of erythrocyte membrane.
