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.

Nexell Therapeutics Inc.'s surging stock moved up another 12% Thursday after the Irvine cancer research company said it received a patent covering in-vitro growth of specialized white blood cells to help the immune system fight bacterial infection and produce platelets to support blood clotting. The stock, which has gained 700% so far this year, closed at $10 a share, up $1.09, in Nasdaq trading.

Only about 20% of all the blood Red Cross collects is used as whole blood, which has a shelf life of 42 days. These are the major blood products: RED CELLS are used for about 70% of all blood needs. Shelf life: 42 days (Can also be frozen and stored for three years, but once reconstituted they must be used within 24 hours. The freezing-reconstituting process is costly and is used primarily for preservation of rare blood.) Diameter: 7 microns (1 micron=0.

HemaCare Corp., a Sherman Oaks company that sells blood-related products and services, said that earlier this month it received licenses from the Food and Drug Administration that allow HemaCare to begin selling some new types of blood products. It said licenses were also granted by the FDA that allow the company to sell some of its existing products outside California for the first time. A total of six licenses were granted by the federal agency.

Scientific and political controversies have coincided in Sacramento to postpone, and perhaps kill, legislation to extend the use of paid donors of blood platelets, which are small cells used in several types of surgery. The subject is too serious to dismiss in this way. The problem is complex. Platelets are in short supply. The Red Cross Blood Bank serving Los Angeles and Orange counties estimates the demand at 40,000 units a year.
