Abstract:
Exocrine pancreatic function was studied in 15 patients with hypothyroidism and 15 healthy subjects by means of the amino acid consumption test, a new tubeless test based on the measurement of plasma amino acid uptake by the pancreas during pancreatic enzyme synthesis stimulation. Nine of the 15 patients were also studied after they had become euthyroid following thyroxine treatment. Pancreatic function was significantly reduced in patients with hypothyroidism compared with healthy subjects. Treatment with thyroxine restored pancreatic function to normal. In two additional hypothyroid patients studied by means of duodenal intubation, pancreatic secretion of both bicarbonate and enzymes was found to be significantly decreased. It was concluded that the thyroid gland plays an essential role in maintaining the functional integrity of the exocrine pancreas in humans.

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...
