The discovery that an enzyme called thrombin has two different ways to tell blood platelets to form a clot might help researchers develop new therapies for clotting disorders like heart attacks and strokes, researchers from UC San Francisco report in today's issue of the journal Nature. When blood vessels are injured or the flesh is cut, thrombin activates platelets--the little cells that clump together to plug blood vessels.

An Amgen Inc. drug increased the number of platelets -- blood cells needed for clotting -- in patients with an uncommon immune disorder, according to research presented at a medical meeting in San Diego. A larger company-funded study is underway to test AMG 531 in patients with immune thrombocytopenic purpura, which causes the immune system to destroy platelets, said lead investigator David Kuter of Massachusetts General Hospital. About 20,000 people in the U.S.

Biopool International Inc., a Ventura producer of medical test kits, said it has developed a new test that would pinpoint people at risk for heart attacks and strokes. The test was presented at a research conference in Israel last month, and focuses on blood platelets. Using the new test, researchers mix the antibodies of chickens with human blood platelets for analysis. The results screen out those at high risk of cardiovascular ailments.

Just months after a post-Sept. 11 surge of blood donations, the American Red Cross is warning that supplies are running low. Most of the Red Cross' 36 regional blood centers have half their normal supply of blood platelets for this time of year, officials said. Blood platelets, which are used to help stop bleeding in cancer patients, spoil after five days. Blood and platelet supplies are typically low during the holiday season. The Sept.

Scientists have found an odd, light-reflecting protein in the body of a squid that could one day prove useful in the design of microscopic optic devices. The discovery, reported in the current issue of Science, was made by researchers at the University of Hawaii and UCLA investigating the light-emitting organ of Euprymna scolopes, the Hawaiian bobtail squid.
There are never enough blood, marrow or organ donors. Even as the American Red Cross emphasizes the need for more Latino blood donors, it and other agencies continue to hope for more donors of all ethnic groups to help cope with a variety of illnesses or emergencies. "People are not aware of the process of organ donations," said Nancy Fox, a director at the Regional Organ Procurement Agency of Southern California (ROPA). "Families are not aware of the wishes of their loved ones."

Amgen Inc. has reported encouraging results in its first human tests of a new drug called MGDF that triggers production of platelets in the blood. If MGDF works, it is hoped that the biotechnology drug will allow doctors to treat cancer patients undergoing chemotherapy who suffer from bleeding and hemorrhages because their blood platelets will not clot. Current medical treatment is to reduce chemotherapy and give patients platelet transfusions.

The mysterious white globules found in bags of donated blood in the South were identified by the American Red Cross as clumps of normal blood components. But why they are forming in such large quantities is unknown. The globules were identified as platelets, white blood cells and fibrin strands. All three components are normally present in donated blood, and some clumping is normal, authorities in Atlanta said. The sheer number of clumps is unusual.
