Abstract
We studied the serum electrolytes in the 727 normal persons who visited Busan University hosptial, Benedict Hospital and Maryknoll Hospital from 1970 to 1976.
The results were as follows:
1. Mean value of the serum Na+ being measured in 729 normal persons was 138.7±6.2mEq/L and 140±6.5mEq/L in 450 male, while 136.8±6.6mEq/L in 279 female.
2. Mean value of serum Cl- being measured in 701 persons was 99.6±5.9mEq/L, and 99.7±6.0mEq/L in 437 male while 100±5.7mEq/L in 264 female.
3. Mean value of serum K+ being measured in 707 normal persons was 4.4±0.9mEq/L in 434 male, while 4.2±0.8mEq/L in 273 female.
4. Mean value of serum Ca+ being measured in 557 normal persons was 4.5±0.6mEq/L and 4.7±0.7mEq/l in 355 male, while 4.3±0.5mEq/L in 202 female.
5. Mean value of serum phosphorus being measured in 94 normol persons was 4.2±0.6mg%, and 4.1±1.0mg% in 65 male, while 4.5±1.5mg% in 29 female.
