The effect of chronic ammonium chloride ingestion on parathyroid hormone function.
The purpose of this study was to examine the effect of ammonium chloride ingestion on the hypercalcemic effect of parathyroid hormone in vivo. Thyroparathyroidectomized rats were given 1.5% ammonium chloride for 5-6 days. Ingestion of ammonium chloride increased serum calcium, but also significantly enhanced the calcium elevating effect of injected parathyroid extract. This result is compatible with a proposed hypothesis that the calcium mobilizing function of the parathyroid hormone may be enhanced by the hormone's own influence on systemic hydrogen ion concentration.
