During the first week of life serum calcium, phosphorus, magnesium, immunoreactive thyrocalcitonin hormone, and parathyroid hormone concentrations were determined daily in 36 preterm and 29 small for gestational age, full term, healthy infants. Preterm babies with early neonatal hypocalcaemia had significantly higher concentrations of serum thyrocalcitonin hormone in the first four days of life...

Data from several laboratories indicate that hepatic mechanisms may have a distinctive role in the metabolism of intact hormone after secretion, a process that accounts, at least partly, for the heterogeneity of circulating parathyroid hormone. Accordingly, we studied the proteolysis of intact hormone by isolated rat Kupffer cells and hepatocytes. Kupffer cells (10(6) cells/ml) and hepatocytes ...

Parathyroid cell hyperplasia is commonly observed in patients with chronic renal insufficiency and largely accounts for refractory secondary hyperparathyroidism. Calcimimetics are newly synthesized compounds that activate a calcium receptor on the parathyroid cell and can suppress parathyroid hormone secretion. The calcimimetic compound AMG 073 has been examined in clinical trials, and the data...

A study was made of the enzymic degradation of 125I-labelled parathyroid hormone by rat kidney microsomes. Incubation with microsomes resulted in rapid destruction of the labelled hormone. The microsomal factor was not separable by dialysis, and the reaction was favoured by pH values in the physiological range. Velocity of the reaction varied directly as the substrate concentration, and additio...

Parathyroid lipoadenomas are a rare and benign variant of parathyroid adenomas that are defined morphologically by an abundance of adipocytes. The clinical manifestations and the laboratory findings are indistinguishable from those of the usual forms of parathyroid adenomas. Unlike parathyroid adenomas, parathyroid lipoadenomas can be functional or nonfunctional. We present a case of a function...

A radioimmunoassay specific for the amino (N) terminal portion of the parathyroid hormone (PTH) molecule (N-PTH radioimmunoassay) has been developed by iodinating synthetic 1-34bovine PTH (1-34bPTH) and using commercially available bPTH antiserum. A radioimmunoassay specific for the carboxyl (C) terminal (C-PTH radioimmunoassay) has been carried out by adding enough amount of 1-34bPTH to the PT...

Giant parathyroid adenomas are uncommon. Its clinical management is challenging. Our study’s goal to share our experience with pre-operative localization of while emphasizing the importance intraoperative hormone (IOPTH) assays in such situations. Here, we present case a 46-year-old woman who was diagnosed adenoma. The aspects, management, and surgical procedure have all been examined. Parathyr...
