Development of the full scope of marrow transplants into man necessarily will be slow, because the science of human tissue immunology must be further -developed, and human material suitable for study is scarce. The exciting possibilities of marrow transplantation in man have already.reestablished OE are interest and researchin this field. One result that can be expected is the development of therapeutic procedures which may be useful in several types of blood diseases. Other discoveries made as a result of current and future research in this field will be even more significant, = - — | oo 2 : i : ' To this end, the Commission is supporting an“estimated 90 percent of the work going on in| bone marrow transplantation,‘and both on-site and off-site laboratories are actively engaged in experimental and clinicalresearch, : ¢ * . . 7 ad oa SYMPOSIUM ON USE OF RADIOISOTOPES IN MARINE. BIOLOGICAL RESEARCH So The Commission, at the invitation of the Italian Committee on Nuclear Research (AEC’s counterpart in Italy), will participate in a workship symposium September -15 to 29. The con- — _ ference will be held at the. Naples Zoological Station, one of the foremost of its kind in the world, aN . . . . ‘Present plans call for sevenAEC scientists actively wrigtgedin. vadtobioiogicat work with aquatic organisms and seven European scientists to give lectures, classroom demonstrations, ‘and laboratory exercises to 20 graduate students. The’ topics to be covered include: (1) the use ~ of radioisotopes in studies of the foods and feeding activities of marine animals, (2) the determination of oceanic primary productivity using carbon 14 tracer techniques, (3) tritium in biology and hydrobiology, and (4) the movement of radiophosphorus in aquatic communities. Equipment taken to Naples by the participating AEC scientists for the laboratory work will be left at the zoological station on indefinite loan.
