Abstract

The Levels of calcium, magnesium, phosphorus and alkaline phosphatase in serum were measured during the first 48 hours of life in 67 normal term infants, to find out normal values of them. The study group was devided into 3 categories, being group of 1-6 hours of life, of 7-24 hours of life and of 25-47hours of life respectively. The results obtained are as follows: 1. During 1-6hours of life, the average level of serum calcium is 4.34+/-0.38mEq/L,magnesium:1.61+/-0.25mEq/L, phosphorus:5.43+/-0.46mg%, alkaline phosphatase:187+/-52U/I. 2. During 7-24 hours of life, the average level of serum calcium is 4.16+/-0.28mEq/L,magnesium:1.46+/-0.23mEq/L, phosphorus:6.03+/-0.62mg%, alkaline phosphatase:161+/-52U/I. 3. During 25-48 hours of the average level of serum calcium is 4.05+/-0.25mEq/L, magnesium:1.55+/-0.16mEq/L, phosphorus:7.16+/-0.51mg%, alkaline phosphatase:148+/-26U/I. 4. During the first 48 hours of life, there is a decrease in serum calcium, while the serum phosphorus is increased.
