These bacteria apparently exert an antagonistic effect against other crganisms which tend to invade the radiation-Ccemeged small intestine. When grown in the leboratory, these bacilli were found to produce antibiotic substances which are herzful to a number of crganisms not affected by currently aveaileble antibiotics. This observeticn may be of significance in the treatment of whole body radiation injury. adium Toxicity Radium svmposium. A svmposiuc wes held in New York on June 13 and 14 to study radium end readcn toxicology. The meesurerernt of rediuz anc recon in tne human bogéy received primary attention. It was concluded that on the besis of present xnoOWLeise, maximum permissible levels for these substances should not be increased. Argonne Study. The Argonne Rational Laboratory mes issuec a preliminary report on its study of 26 persons who were given raizicc intre- venously some 2° yeers ego as Wtrestsent fer a variety of conditions. About 100 such individuals heve been located, all of when will be studied The resulting Sata will be a desis for more definitive estixstes of the toxicity of plutoniuc end other elrhs-emitting heevy elererits used in the atomic energy rrogren.

In preliminary work blood transfusions and antibiotics, singly and in combination, heave been administered to a small number of anirals. ——s DOE ARCHIVES eee . Body protection. Scientists at Argonne National Laboratory have pursued their discovery, described in the preceding report, that in administering near-lethal and lethal doses of radiation to mice, the shielding of the spleen with lead greatly increeses the probability of survival. The substance supplied by the shielded spleen appears to stimalete irrediation-damaged bone marrow to resume production of red blood cells. Accumulating evidence suggests that this stimulating factor, also found in normal bone marrow and embryonic tissue, is not specific to each species of mammal, and therefore may offer a promising approach to the treatment of whole body radiation injury, in which restoration of red blood cells is so important. enn 1 Investigations of Radiation Effects ( wy + aw eenames ~ meee eerae lar accident should occur. ee 1 - piAgsobawMOP RDIS!
