A red respiratory pigment found in certain forms of sea anemones: When Mary was studying zoology, she found an article about actinohenmatin, which was the crimson color of the respiratory organ of a marine polyp which resembled a flower.

A form of hemophilia discovered by Erik von Willebrand; a genetic disorder that is inherited as an autosomal recessive trait; characterized by a deficiency of the coagulation factor and by mucosal bleeding.

An inherited bleeding disorder in which a clotting protein called von Willebrand factor is deficient or defective. Von Willebrand factor is made by cells lining the wall of blood vessels.

When vessels are damaged, platelets normally clump at the site of the injury. Von Willebrand factor acts as glue to help the platelets clump.

The Von Willebrand factor is also a carrier of clotting factor VIII, another protein that helps the blood to clot.

A reduction in peripheral blood counts resulting from impairment of hematopoiesis (lack of blood formation).

Not hemolytic or not destructive of blood corpuscles.

The lack of blood formation; such as, in aplastic anemia (a form of anemia, or lacking red blood cells, which occurs when the bone marrow ceases sufficient red and white blood cell production).

A substance that inhibits or prevents hemagglutination: Judy found out that an antihemagglutinin could be an antibody that would suppress the coagulation of red blood cells.

1. Arresting or reducing hemorrhage.
2. An agent that prevents or stops hemorrhage.

Dependent upon the presence of autologous blood.

1. Haemolysis (destruction of red blood cells which leads to the release of hemoglobin from within the red blood cells into the blood plasma) occurring in certain diseases as a result of an autohemolysin (an autoantibody that acts on the red blood cells in the same person in whose body it is formed).
2. Hemolysis of the blood cells of a person by his own serum.

Voluntary exudation or ejection of nauseous or poisonous blood by certain insects as a defense against predators.

Treatment of disease with the patient's own blood, withdrawn by venipuncture and then injected intramuscularly.

1. The presence of bile and blood in the thorax (area of the body located between the neck and the abdomen that contains the lungs, the heart and part of the aorta).
2. A pleural effusion (excess fluid between the two membranes that envelop the lung) containing bile and blood.

The most common symptoms of pleural effusion are chest pain and difficulty breathing (dyspnea). Many pleural effusions cause no symptoms but are discovered during a physical examination or seen on a chest x-ray, which is the most convenient way to confirm the diagnosis.

Many conditions are capable of causing pleural effusion, including heart failure and uremia (kidney failure), hypoalbuminemia (low levels of albumin in the blood), infections (TB, bacterial, fungal, viral), pulmonary embolism, and malignancies (metastatic tumors, Hodgkin disease, mesothelioma).

An important blood-sucking species of Cimex parasitic to people; the oriental bedbug.

Relating to the state of being cold-blooded: Some cryohemic animals are fish, reptiles, and ticks.

1. A bloody flow of tears.
2. The discharge of tears mixed with blood.
3. Hemorrhagic discharge from the lacrimal sac.
