Effect of enhanced bromide intake on the concentration ratio I/Br in the rat thyroid gland
Biological Half-life of Bromide in the Rat Depends Primarily on the Magnitude of Sodium Intake
Summary The parallel course of the excretion rates of bromide and sodium ions was demonstrated in adult male and female rats administered simultaneously with potassium 82 Br-bromide and 24 Na-sodium chloride. The animals were exposed to various intakes of sodium ions accompanied with five different anions: Br -, Cl -, HCO 3 -, ClO 4 -, and SCN -. Regardless of the anion accompanying the sodium ion, the excretion rates of 82 Br -and 24 Na + ions were proportional to the magnitude of sodium intake in the animals. Hence, we have proved our hypothesis that the biological half-life of bromide depends on the magnitude of sodium intake rather than on the intake of chloride
