The experiment was carried out on 8 healthy female college-student 19-22 years old and they were fed three times a day with a test meals for 7 days of each experimental period. The test meals used were pulses protein diet, fishes protein diet and meat protein diet, and they supplied for each subject per day are as follows : a) The pulses protein diet; protein 87.69 (pulses source : 45.8g) fat: 41.1g (pulses source : 22.99) carbohydrate : 411.9g calcium : 605.0㎎ (pulses source: 399.9㎎) phosphorus: 1,083.3㎎ (pulses source: 497.5㎎), and 2,367 ㎉ b) The fishes protein diet; protein: 88.1g (fishes source: 34.89) fat : 17.0g (fishes source: 3.29) carbohydrate : 446.29 calcium : 442.4㎎ (fishes source: 114.1㎎) Phosphorus : 1,369.3㎎ (fishes source : 399.0㎎), and 2,310 ㎉ c) The meat protein diet: protein : 87.60 (meat source: 40.2g) fat: 25.99 (meat source: 6.39) carbohydrate : 431.79 calcium: 360.6㎎ (meat source: 12.0㎎) phosphorus: 798.7㎎ (meat source : 41.6㎎), and 2,359 ㎉ The absorption rates of protein, fat, carbohydrate. calcium and phosphorus in each diet, and 17-ketosteroid excrcted in urine were determined. The results obtained are summarized as follows: 1. The protein absorption rate of the pulses protein diet was lower than that of the fishes and meat protein diet. 2. The nitrogen balances in the pulses (+1.4±0.2g), fishes (+2.1±0.39) and meat (+2.4±0.39) protein diet were positive balances respectively. 3. The fat absorption rate of the fishes protein diet (60.9±2.6%) was significantly lower than that of the pulses and meat protein diet. 4. The carbohydrate absorption rates were 94.8±3.5∼96.2±0.4% in each diet, and so it seems to be absorbed almost entirely but cellulose. 5. The calory utillization rates in each diet were .6±0.4∼91.0±0.4%. 6. The calcium absorption rates of pulses protein diet (30.1±1.8%) were significantly lower than those of the fishes (52.5±2.5%) and meat protein diet (49.5±2.0%). 7. The phosphorus absorption rates of the pulses protein diet (45.9±2.3%) were significantly lower than those of the fishes (78.7±2.8%) and meat protein diet (81.3±2.2%). 8. The 17-ketosteroid contents excreted in urine of pulses protein diet (4.81±0.23㎎) were higher than those of the fishes (3.76±0.18㎎) and meat protein diet (3.30±0.12㎎), hut it showed no remarkable change of contents for each subject with the same diet. In the view of the above results; it can be seen that the absorption rates of each nutrient were good in the meat protein diet, but the absorption rates of protein, calcium and phosphorus in the pulses protein diet and those of fat in the fishes protein diet were not so good, respectively.

The effect of various protein sources on the contents of sulfhydryl group in liver and cholesterol in plasma and liver of rats were observed in this study. Experimental animal, 72 male albino rats, 45±5 day of after birth were used. Either rice or wheat was made as a basic diet, and whole milk powder, egg powder, fish flour (anchovy flour) and soybean flour of 5% level, respectively, was supplemented to each basic diet as protein source. Each animal group was fed on the corresponding diet for 96 days, and then the sulfhydryl group in the liver and the cholesterol in the liver and plasma were determined. The results are summarized as follows: 1. The sulfhydryl group contents in the liver shows no difference between each group of protein supplemented, and between groups of basic diets and protein supplemented. 2. The total cholesterol contents in the liver does not change reqularly as each protein source is supplemented, to rice, but increase, to wheat diet. 3. The free cholesterol contents in the liver increases through each protein supplement to basic diets. 4. The total cholesterol in the plasma is not influenced by each protein supplemented, and groups of protein supplemented show similar contents to group of either rice or wheat. The above results leads to the conclusion that the cholesterol contents in the liver and plasma more or less affected by the kinds of protein source.
