| Description | The biological half-life of bromide, as substituting for sodium or chloride, was investigated with the aid of the radionuclide 82Br in lactating and non-lactating female rats as well as in young rats of varying ages. Non-weaned young rats (12 d) had the highest half-life (269 h) and lactating dams the lowest (44 h). The determined values demonstrated that non-weaned young apparently conserve Na, while lactating dams, due to their large food intake, waste Na. The parallel course of the excretion rates of sodium and bromide ions was demonstrated in adult male rats administered simultaneously with 24Na-sodium chloride and 82Br-bromide. These excretion rates were inversely proportional to the magnitude of sodium intake in the animals. |
