A SIMPLE AND PRECISE METHOD FOR THE SIMULTANEOUS MEASUREMENT IN MAN OF PLASMA VOLUME, RADIOBROMIDE SPACE, EXCHANGEABLE POTASSIUM, AND EXCHANGEABLE SODIUM.

Abstract A simple method for the simultaneous estimation of plasma volume, extracellular fluid volume, total body sodium, and total body potassium is described. Its use provides important advantages in both clinical and investigative medicine. The procedure utilizes T-1824, Br 82 , Na 22 , and K 42 , Evans blue dye is determined spectrophotometrically. Radiobromide is separated chemically by use of a simple ion exchange column containing Amberlite IRA-400. The remaining mixture of Na 22 and K 42 is delineated by short-term differential decay counting. Data are presented which demonstrate that this method gives results which agree with published values for normals obtained by other methods. In addition, when dietary sodium intake is altered, the volumes of distribution of bromide ion change in the expected directions.

The determination of protein-bound iodine131 with anion exchange resin column.

Abstract A direct comparison of the protein-bound iodine 131 determination by the trichloroacetic acid precipitation technique and the Amberlite anion exchange column procedure was made in 100 consecutive thyroid function studies, and a close agreement between the results of these two methods was established. The simplified and time-saving procedure for the determination of protein-bound iodine 131 , employing an Amberlite anion exchange column, is described.
