The purpose of the present study was to determine (1) the normal velues of serum magnesium in children from birth to 15 years of age; (2) to compared the values in breast fed and artificially fed newborns and in different weight group at birth; (3) to determined the serum magnesium levels in various disease states;
The results obtained are summarized as follows:
1. The mean level of serum magnesium in 41 full-term newborn during the first 4 days of life was 1.94±0.27㎎/100㎖, for 205 children from 1 month to 15 years of age was 2.12±0.27㎎/l00㎖, and for 52 cord bloods was 1.89±0.27㎎/100㎖.
2. There was a gradual rise in serum magnesium levels with postnatal age during the first 4 days of life.
3. The mean value in breast-fed infant was higher than in infant fed artificially and tend to be had a highest or lowest values on the third and fourth day of life.
4. There was no relationship between birth weight and serum magnesium levels.
5. There was no difference in values of magnesium found among the patients with convulsive disorders.
6. The mean value of magnesium in dehydrated infants was within normal limits.
7. Patients with acute glomerulonephritis had a higher normal levels and patients with nephrotic syndrome had a lower normal levels.
8. The serum magnesium level in the newborn with various pathologic conditions had no significant difference from normal conditions.
9. There was no significant correlation between serum calcium and magnesium in the hypocalcemic infants.
