because there is only the defects in function of platelets in hemophilia and not reduction in number of platelets!
platelets
Certain types of snake venom - to use the correct term - can be used in humans to treat diseases such as hemophilia (where the patient lacks platelets in the bloodstream to stop bleeding)
The medical term for platelet is "thrombocyte." If you have a decreased amount of platelets, the condition is "thrombocytopenia" or thrombopenia.
The platelets count of the sick person was very low. It means the count of protective cells in the body.
Hemophilia.
hemophilia B is also known as Christmas disease because Stephen Christmas was the first patient with the disease, and hemophilia A is just known as classic hemophilia.
Hemophilia is a serious disease, because even if the person has a small cut they can bleed to death because they don't have platelets to stop the cut from bleeding.
That is frequent finding to see that patient with hemophilia gets the swelling, usually of one of the knee joint.
The platelets and plasma clotting factors are extracted from donated blood and concentrated for use. These factors are used to treat people with such clotting disorders as hemophilia.
A low platelet count, called thrombocytopenia, causes the blood to fail to clot easily. A healthy platelet count should be between 150,000 and 450,000 platelets per micro liter of blood. A level lower than 150,000 platelets indicates thrombocytopenia.
It is named after the first patient who was described with the symptoms of Hemophilia type B, Stephen Christmas.
