TL;DR: Total and nephrogenous urinary cyclic AMP, serum Parathyroid Hormone (PTH) and ionized calcium (Ca) levels were determined in 8 normal subjects, and 16 normocalcemic and 9 hypercalcemic patients with lung cancer.

TL;DR: In the rat, EDTA and isoproterenol stimulated PTH secretion, whereas high calcium and propranolol inhibited it, suggesting that both calcium and β-adrenergic stimuli affect P TH secretion by separate initial pathways.

TL;DR: In vitro observations indicate that histamine can stimulate iPTH secretion by a direct effect on the parathyroid cell and that this is probably a specific effect via histamine H2 receptors because the effect was blocked by the H2 receptor antagonist, cimetidine.

TL;DR: The studies indicate that, similar to the shortterm effects observed in previous studies, long-term modification of β-adrenergic stimuli can affect PTH and CT secretions.

TL;DR: Allotransplantation of fresh, 1 or 2 week cultured parathyroid glands from Wistar rats to Fischer rats resulted in prompt rejection of the transplant in the muscle site; whereas transplantation into the adrenal site offered slightly prolonged survival, suggesting that the latter is a privileged transplantation site.
