title: [Determination of sodium and potassium in feces of infants with diarrhea disease].
abstract: Two male infants, with second degree malnutrition and diarrhea were the subjects of this study. Samples of stools were collected in eight periods of eight hours each to determine: dry and moist weight, concentration of sodium and potassium in each sample. The correlation fluid volume against concentration of sodium and another one of lost volume expressed in milliliters per kilogram per period against concentration, corresponded to r = 0.83 and 0.86 with p less than 0.01. As expected, no correlation was found for the potassium ion when behaving as independent variable.
