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. Calcitonin, produced by cells in the thyroid gland, acts directly on osteoclasts (via receptors on the cell surface for calcitonin). The osteoclasts shrink and stop bone resorption. Bone biopsies from patients treated with the drug show no effects on mineralization.It has a short half-life.alcitonin.
