OBJECTIVE A subset of parathyroid adenomas contains a relative overabundance of oxyphil cells that are capable of greater technetium Tc 99m sestamibi tracer uptake and retention than other cell types. We examined whether the presence of oxyphil cells augments the sensitivity of technetium Tc 99m sestamibi preoperative localization and whether the histologic findings of a lesion could be predict...

1. The effect of parathyroid hormone on gastric bicarbonate secretion was determined in the anaesthetized guinea pig. Subcutaneous injections of bovine parathyroid hormone (75 U.S.P units day-1 kg-1) for 7 days caused a significant increase in HCO3- output. There was also a rise in K+ output and a slight elevation of H+ secretion. A similar increase in HCO3- output occurred after acute intraven...

The effects of parathyroid hormone upon substrate decarboxylation and ion uptake and release in isolated mitochondria in terms of specificity, sensitivity, and the correlation between action in vivo and in vitro were studied, Parathyroid hormone added to isolated liver or kidney mitochondria in vitro stimulated the decarboxylation of a variety of Krebs’ cycle intermediates. This decarboxylation...

Ultrasonically guided fine needle aspiration of suspect parathyroid tissue to determine parathyroid hormone concentration Since the study of Arima et al,1 several reports have confirmed that enlarged parathyroid glands can be located preoperatively using ultrasound. A general problem has been the difficulty of distinguishing nodular thyroid lesions from enlarged parathyroid glands.2 3 We report...

Parathyroid hormone and calcium were measured in plasma taken from pregnant women at term and from the umbilical veins of their infants at birth. Three assays were used to measure parathyroid hormone, a cytochemical bioassay of bioactivity and two immunoradiometric assays, one specific for the amino terminus, the other specific for the carboxy terminus of the parathyroid hormone molecule. Plasm...

Correction: Time Course of 25(OH)D 3 vitamin D3 as well as PTH (parathyroid hormone) during fracture healing of patients with normal and low bone mineral denisty (BMD) " Time course of 25(OH)D3 vitamin D3 as well as PTH (parathyroid hormone) during fracture healing of patients with normal and low bone mineral density (BMD) " [1], the last name of Christoph Wölfl was incorrectly spelt as Wöfl. I...

The effects of treatment with vitamin D, calcium, or lactose on the responsiveness of vitamin D-deficient rats to parathyroid hormone were compared. In the absence of vitamin D, parenteral calcium or dietary lactose administration resulted in increases in serum calcium concentration although not to the normal values obtained in animals given vitamin D. Dietary lactose also partially restored th...
