Calcitonin is secreted by several endocrine tumors (e.g., a medullary carcinoma of the thyroid); therefore, it is used as a tumor marker to monitor progress of recovery after surgical resection of the tumor. Although calcitonin is used to treat patients with several disorders associated with excess bone resorption (e.g., osteoporosis and Paget's disease), no clinical disease has been associated with its deficiency or even its absence after total thyroidectomy (removal of thyroid gland).

Most of the tumors of endocrine gland are hormonally active and are responsible for hormone overproduction. However, some tumors of endocrine glands do not produce hormones but compress neighboring organs or cause destructions of other organs due to metastasis. An example of such a tumor is thyroid cancer that can metastasize throughout the body without presenting signs of thyroid hormone overproduction (hyperthyroidism).

Cardiac Tamponade
The condition in which excess fluid (blood or pericardial effusion) rapidly accumulates in the pericardial cavity is called "cardiac tamponade". It is commonly caused by both blunt and penetrating chest injuries and by myocardial rupture or pericarditis (inflammation of pericardium). This is a life-threatening condition in which accumulating fluid compresses the heart, preventing the heart's chambers from filling properly with blood. Relieving the pressure is usually accomplished with pericardiocentesis (a procedure to drain the fluid from the pericardial cavity).

Cardiac Arrest
In the sudden cessation of normal heart rhythm leading to abrupt cessation of blood circulation called "cardiac arrest", the conducting system of the heart fails to produce or conduct electrical impulses that cause the heart to contract and supply blood to the body. Sudden cardiac arrest is a medical emergency; first-aid treatment such as cardiopulmonary resuscitation (CPR) and defibrillation (delivering a dose of electrical energy to the heart) can improve the chances of survival. If not treated, cardiac arrest leads to sudden cardiac death.

Hypercellular bone marrow is characteristic of bone marrow affected by tumors originating from hemopoietic cells.

Red bone marrow
Even in hemopoietically active bone marrow in adult humans -such as that in the ribs, vertebrae, pelvis, and shoulder girdle- about half of the bone marrow space is occupied by adipose tissue and half by hemopoietic tissue.

Yellow bone marrow
Inactive bone marrow is called "yellow bone marrow". It is the chief form of bone marrow in the medullary cavity of adult bones that are no longer hemopoietically active, such as the long bones of the arms, legs, fingers, and toes. In these bones, the red bone marrow has been replaced completely by fat... The yellow bone marrow retains its hemopoietic potential, however, and when necessary, as after severe loss of blood, it can revert to red bone marrow.

Although lymphocytes continuously proliferate in the peripheral lymphatic organs, the bone marrow remains the primary site of lymphopoiesis in humans.

Clinical testing of cytokines
The isolation, characterization, manufacture, and clinical testing of "cytokines" (proteins and peptides that are signaling compounds) in the treatment of human disease are major activities of the rapidly growing biotechnology industry. Several hemopoietic and lymphopoietic cytokines have been manufactured by recombinant DNA technology and are already used in clinical settings. These include "recombinant erythropoietin, G-CSF, GM-CSF, and IL-3; others are under active development. GM-CSF (sargramostim, Leukine) is used clinically to stimulate production of white blood cells (WBC) following chemotherapy and to accelerate WBC recovery following bone marrow transplantation.

Thrombocytopenia
"Thrombocytopenia" (a low blood platelet count) is an important clinical problem in the management of patients with immune-system disorders and cancer (i.e., leukemia). It increases the risk of bleeding and in cancer patients often limits the dose of chemotherapeutic agents.

In normal blood, reticulocytes constitute about 1% to 2% of the total erythrocyte count. However, if increased numbers of erythrocytes enter the bloodstream (as during increased erythropoiesis to compensate for blood loss), the number of reticulocytes increases.
