This study was designed to elucidate the effects of administration with dietary iron and fat-free diet on the contents of unsaturated fatty acid in phospholipid molecules, vitamin E contents and malondialdehyde contents in liver, kidney, muscle and testis of the male rats.
The rats were divided into 3 experimental groups, namely, control, iron injection and fat-free diet administration groups. The control group was fed. with normal diet, iron injection group injected intraperitoneally 20㎎ of ferric hydroxide/100g of body weight 20 times every 3 days and fat-free diet group administered lipid extraction diet with hexane in normal diet.
All experimental groups were maintained for 60 days with feeding on the respective ration.
The results obtained were summarized as follows:
1. In the mean contents of unsaturated fatty acid in phospholipid of liver, kidney, muscle and testis among groups, control group was 21.31㎎/g, 19.38㎎/g, 1.67㎎/g, 13.68㎎/g, iron injection group was 13.83㎎/g, 16.53㎎/g, 0.71㎎/g, 10.1l㎎/g and fat-free diet group was 21.07㎎/g, 19.38㎎g/g, 1.49㎎/g and 13.40㎎/g, respectively.
2. In the mean contents of vitamin E in liver, kidney, muscle and testis among groups, control group was 6.77mg/g, 1.93㎎/g, 0.12㎎/g, 0.17㎎/g, iron injection group was 3.16㎎/g, 0.86㎎/g, 0.07㎎/g, 0.09㎎/g and fat-free diet group was 7.41㎎/g, 1.50㎎/g, 0.11㎎/g and 0.l6㎎/g, respectively.
3. In the mean contents of malondialdehyde in liver, kidney, muscle, testis and serum among groups, control group was 11.29nM/0.1g, 23.25nM/0.1g, 42.47nM/0.1g, 7.01nM/0.1g, 4.33 nM/㎖, iron injection group was 34.98nM/0.1g, 40.55nM/0.1g, 72.21nM/0.1g, 12.26aM/0.1g, 11.27nM/㎖ and fat-free diet group was 8.07nM/0.1g, 20.63nM/0.1g, 39.92nM/0.1g, 6.95nM/ 0.1g and 4.27nM/㎖, respectively.
