Background. Acute ischemic stroke (AIS) is characterized by the sudden loss of blood circulation to an area of the brain, typically in a vascular territory, resulting in a corresponding loss of neurologic function.troke symptoms can result from inadequate cerebral blood flow because of decreased blood pressure (and specifically, decreased cerebral perfusion pressure) or as a result of hematologic hyperviscosity from sickle cell disease or other hematologic illnesses, such as multiple myeloma and polycythemia vera.
Calcitonin. Calcitonin is a peptide hormone produced by cells within the thyroid gland. Calcitonin secretion is stimulated by high blood calcium concentrations, and it acts as a physiologic antagonist to PTH. Osteoclasts have receptors for calcitonin, but the effects are transient.rowth hormone. Growth Hormone (GH) is a growth promoting hormone produced by the pituitary gland. It is anabolic, which means it stimulates bone formation. Growth hormone also: * stimulates the production of insulin-like growth factor 1 (IGF-1) by the skeleton.
Calcitonin is the other major hormone involved with calcium regulation. Parathyroid hormone (PTH), produced by the parathyroid gland, increases the level of calcium in the blo â¦ od. It usually accomplishes this by increasing the resorption rate (taking back) from bone.Calcitonin does the exact opposite and reduces calcium in the blood.arathyroid hormone (PTH) and calcitonin regulate blood calcium levels. PTH increases the calcium concentration in the blood, and calcitonin decreases it. 2 people found this useful. Edit.
