抄録
Sodium (Na), potassium (K), calcium (Ca), phosphorus (P), magnesium (Mg) and zinc (Zn) balances were studied for three consecutive days using five healthy, male subjects in their 20s. Based on the results of the study, the correlation between the intake levels and excretions in stool and urine or serum concentrations was analyzed.<br>1) In the balance study, the ingested Na, K and P were mostly excreted in urine. The excretion rate in urine as against the intake was highest for Na at 85%, followed by 84% for P and 74% for K. Conversely, Ca, Mg and Zn were excreted in stool at higher rates, excretions in urine being as low as 38% for Ca, 25% for Mg and 7.1% for Zn.<br>2) Analysis of the correlation between the intake and excretion in stool revealed that only K showed a positive correlation with statistical significance.<br>3) Na (r=0.974) and K (r=0.891) showed statistically significant positive correlation between the intake and excretion in urine.<br>4) There was no statistically significant correlation between the intake and serum concentration of any of these minerals.<br>5) Of the methods for estimating intake levels of Na, K, Ca, P, Mg and Zn from their excretions in urine and stool and serum concentrations, estimation from urinary chlorine is well known. The present study showed that excretions of Na and K in 24 hour urine are also useful for estimating the intake levels of these minerals.
