The effect of dietary restriction was obserbed in Albino rats. Dietary restriction was at 2 levels: 10%, 20%, 30 males and same number of females of Albino rats, aged $30{\sim}40$ days were devided into following 6 groups, 5 rats each. 1 group; rice standard group 2 group; 10% restriction of rice standard 3 group; 20% restriction of rice standard 4 group; 65% rice+35% chinese cabbage group 5 group; 10% restriction of 65% rice+35% chinese cabbage 6 group; 20% restriction of 65% rice+35% chinese cabbage The rats were kept in individual cage and given 6 different diet for 7 weeks. The results of this study were elucidated as follow. 1. Final body weight was not obserbed any significant differences between non-restriction group and 10% restriction group, but 20% restriction group revealed the decrease of body weight. 2. According to dietary restriction, final organ weight was almost decreased in the restriction group of rice+chinese cabbage, and in rice standard group, there were no significants differences between none-restriction group and 10% restriction group, but organ weight was sharply decreased such as Liver, Heart, Kidney, Adrenal, Spleen in 20% restriction group. Sex organ weight of female was increased but weight of male was decreased in 20% restriction group of rice standard group. 3. The result of biochemical analysis such as nitrogen retention, serum cholesterol, glucose of urine, feces, and serum, and lipid of feces and liver, was not revealed any significant diffences, but in 20% restriction group, urinary glucose and serum glucose levels were somewhat decreased, and liver nitrogen level was increased. 4. Therefore there is no effect on albino rats by 10% restricted diet. It can be concluded that it is possible to restrict the diet within 10%.
