Abstract
|
|
|
The effects of various levels of copper(Cu) intake on the concentrations of copper, iron (Fe) and zinc(Zn) in rat tissues were studied in growing rats. For different groups the drinking water was supplemented with O(control). 25. 50. 100 and 200ppm Cu(as copper sulphate) for 1 day respectively. All animal groups were fed with the control diet (Cu contents, 12.8r㎎/㎏ diet) during the experiment.
At the end of the 4 week experiment, body weight gain was slightly lower in the Cu supply groups than in control group. Liver and serum Cu were significantly higher in 50, 100 and 200ppm Cu of male and in 200ppm Cu of female than in control groups. Spleen Cu was significantly increased by the supplementation of Cu.
Liver and heart Fe of male and heart Fe of female were increased by incresing supplementary Cu levels. In 50ppm Cu group, liver, spleen and kidney Fe of female increased but the others did not. Fe of tissues was different in male and female rats according to Cu levels supplied.
Serum Zn of male and female was significantly lower in 50, 100 and 200ppm Cu groups than in control and 25ppm Cu groups. When supplemented with Cu levels there were no significant differences among groups for liver, kidney, spleen and heart Zn as well as heart and kidney Cu.
