각 49예의 모혈 및 태혈 37예의 정상비임부혈청에 대한 Calcium량을 Clark-Collip법으로 측정하고 각 50예의 모혈 및 태혈 38예의 정상비임부혈에 대한 염화물량을 Schales and Schales법으로 측정하였던 바 다음과 같은 결과를 얻었다. 1. 태아혈청내 Calcium량은 평균 11.84±0.18mg/100ml.이었고 모체혈청내 Calcium량은 평균 11.04±0.17mg/100ml.로서 태아측에서 모체측보다 평균 0.80mg/100ml. 높은 성적을 얻었으며 유의차가 있었다.(t≒3.2, 0.01＞＞p＞0.001) 정상비임부혈청내 Calcium량은 평균 11.38±0.19mg/100ml.로서 모체측보다 평균 0.34mg/100ml.높았으나 유의차는 없었다.(t≒1.36, 0.3＞p＞0.2) 2. 태아혈청내 염화물량은 평균 109.86±1.60mEq/L.이었고 모체측의 그것은 평균 103.54±1.18mEq./L.로서 태아측이 모체측보다 평균 6.32mEq./L. 높은 성적을 얻었으며 유의차가 있었다.(t≒3.19, 0.01＞＞p＞0.001) 정상비임부혈청내 염화물량은 평균 102.1±1.20mEq./L.로 모체측보다 평균 1.44mEq./L. 낮은 성적을 얻었으나 유의차는 없었다.(t≒0.85, 0.5＞p＞0.4)

The calcium level in the sera of the parturients and the cord blood of 49 cases as well as 37 healthy non-pregnant women as control was determined by Clark-Collip method. The chloride level in the sera of the parturients and cord blood of 50 cases as well as 38 healthy non-pregnant women as control was determined by Schales and Schales method . The results obtained are as follows: 1) The mean value of calcium in the cord blood was 11.84±0.18mg./100ml. and in the parturients 11.04±0.17mg./100ml. The mean value of calcium of the cord blood was 0.80mg./100ml. higher than that of the parturients which is statistically significant.(t≒3.2, 0.01＞＞p＞0.001) The mean value of calcium of non-pregnant women was 11.38±0.19mg./100ml., 0.34mg./100ml. higher than that of the parturients. This difference is not significant statistically.(t≒1.36, 0.3＞p＞0.2) 2) The mean value of chloride in the cord blood was 109.86±1.60mEq./L. and in the parturients 103.54±1.18mEq./L. The mean value of chloride of the cord blood was 6.32mEq./L. higher than that of the parturients. This difference is statistically significant.(t≒3.19, 0.01＞＞p＞0.001) The mean value of chloride of non-pregnant women was 102.1±1.20mEq./L. The difference in the mean value of the parturients is not significant statistically.(t≒0.85, 0.5＞p＞0.4)
