Outward movement of hemoglobin and $K^+$ ion across rabbit erythrocyte membrane after heating, cooling and in acid medium was studied. One milliliter of rabbit blood was centrifuged and packed red cells were obtained. Packed red cells were resuspended by addition of 4 ml of 0.9% NaCl solution and were subjected to heating $(57^{\circ}C\;for\;5\;minutes)$ or cooling $(-4^{\circ}C{\sim}-8^{\circ}C\;of\;-10^{\circ}C{\sim}-11^{\circ}C\;for\;10\;minutes) $. For acid medium experiment packed ref cells were resuspended by addition of 4 ml of acid medium of PH 4.5 consisting of 0.01% glacial acetic acid in 0.85% NaCl solution and kept standing for 10 minutes. All red cell suspensions were centrifuged again and packed red cells were separated. This packed red cells were again suspended in 4 ml of NaCl solution of 0.8%, 0.7%, 0.6%, and 0.5% concentration respectively and kept standing for 20 minutes. The concentration of hemoglobin and $K^+$ in the supernatant of the above red cell suspensions were measured and the following results were obtained. 1. Outward movement of hemoglobin and $K^+$ was greatest in red cells subjected to heating. The movement paralled to the osmolal concentration gradient between extra- and intra-cellular phase of red cells. 2. In acid medium the outflux of hemoglobin and $K^+$ increased as compared to the control. 3. In red cells subjected to the cold of $-10^{\circ}C{\sim}-11^{\circ}C$ the outflux of hemoglobin and $K^+$ increased. Whereas in the environment of $-4^{\circ}C{\sim}-8^{\circ}C$ there was no change in the outflux of $K^+$. The he-moglobin outflux showed rather a decreased as compared to tile control.

Maximal oxygen intake was measured in 28 high school girls and 5 basket ball players by means of tread-mill test. The school girls had an average age of 18.6 years (ranged from 17.4 to 19.8 years) and they were nonathletes. The ball players were top korean player and 18.3 years old in average. Interrelationship between body composition and maximal oxygen intake was assessed. Body fat was calculated from the known formula obtained in the high school girls of comparable age by the method of densitometry and skinfold thickness measurement. The following results were obtained. 1. Total body fat of high school girls was 23.7% body weight and 18.2% in girl basket ball players. The latter figure was almost same as that of boys of same age. 2. Maximal oxygen intake of high school girls was 2.23ℓ/min, 42. 5㎖/min/㎏ body weight and 55. 8 ㎖/min/㎏ lean body mass. The ratio to the resting oxygen intake was 12.1. 3. Maximal oxygen intake of girl basket ball player was 2.86ℓ/min, 47.3㎖/min/㎏ b. wt. and 60.4㎖/min/㎏ LBM. This value was greater than that of non-athletic girls. The ratio of maximal oxygen intake to the resting intake was 13.0. 4. In high school girls there were high degrees of correlation between body weight and lean body mass and maximal oxygen intake, namely, r=0.625 and r=0.662, respectively. The following regression equations were obtained. Max VO₂ (1)=0.0373 × Body weight (㎏) + 0.266, Max VO₂ (1)=0.0537 × LBM (㎏) + 0.071. 5. Maximal lung ventilation in high school girls was 71.5ℓ/min and the ratio to resting value was 12.6. Ventilation equivalent in resting state was 31.6 and maximal ventilation equivalent was 32.3. 6. Maximal lung ventilation in the girl basket ball player was 80.1 ℓ/min and the ratio to the resting ventilation was 11.9. Ventilation equivalent in resting state was 29. 8 and maximal ventilation equivalent was 27. 3. This low value as compared to the non-athletic girls was interpreted as the effect of sports training in the basket ball player. 7. Maximal heart rate differed in the two experimental groups. Maximal heart rate of non-athletic high school girls was 198.9 beat/min and was 2.7 times that of resting heart rate. In the athletic girls maximal heart rate was 191.2 beat/min and was 3.1 times that of resting value. Maximal oxygen pulse of non-athletic girls was 11.2 ㎖/beat and 15.1 ㎖/beat in the athletic girls. Those data also were interpreted as an effect of sports training. 8. There was a high degree of correlation between maximal oxygen intake and maximal lung ventilation, namely, r=0.769.

The normal lung volumes were determined and subdivided under sitting position in 48 middle school girls, 49 high school girls and 44 house wives. All subjects were free of pulmonary and vascular diseases. The vital capacity was measured by Mckessons spirometer and the residual volume was determined by Rahn's three breathing method. 1. The lung volumes (BTPS) of middle school girls determined were: $RV\;0.59{\pm}0.11l\;FRC\;1.45{\pm}2.22l\;VC\;2.68{\pm}0.29l$ 2. The lung volumes (BTPS) of high school girls determined were: $RV\;0.83{\pm}0.19l\;FRC\;1.9{\pm}0.25l\;VC\;3.15{\pm}0.24l$ 3. The lung volumes (BTPS) of house wives determind were: $RV\;0.95{\pm}0.61{\ell}\;FRC\;2.1{\pm}0.25{\ell}\;VC\;3.06{\pm}0.29l$ 4. The calculated residual ratio $(RV/TLC{\times}100)$ were: $17.7{\pm}2.57%$ in middle school girls and $20.6{\pm}3.65%$ in high school girls and $24.0{\pm}2.31%$ in house wives 5. The functional residual ratio $(FRC/TLC{\times}100)$ were: $43.7{\pm}5.98%$ in middle school girls and $48.8{\pm}4.41%4 in high school girls and $52.6{\pm}5.38%$ in house wives. 6. The correlation coefficients between vital capacity and total lung capacity were r=0.96 in middle school girls and r=0.986 in high school girls and r=0.856 in house wives. 7. The regression equations were obtained follows: $TLC(l) =1.105{\times}VC+0.304$ (in middle school girls) $TLC(l) =1.551{\times}VC-0.902$ (in high school girls) $TLC(l) =0.999{\times}VC+0.954$ (in house wives)
