(Greek: blood)
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.
2. An agent that prevents or stops hemorrhage.
2. Hemolysis of the blood cells of a person by his own serum.
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).
2. A condition of having cold blood.
2. The discharge of tears mixed with blood.
3. Hemorrhagic discharge from the lacrimal sac.
