  • Use of radioactive isotopes in clinical investigation is limited because of the hazard of radiation, but, by labeling the compound after isolation, it is possible to overcome this difficulty in some instances. This can be done by neutron activation. In studying the composition and the metabolism of phospholipids in human beings, it is not always possible to administer enough radioactive /sup 32/P; however, after the separation of the phospholipids from human tissue, the P could be activated by neutrons for further analysis. Thus techniques are described for the analysis of phospholipids in human erythrocytes, thrombocytes, bile, intestinal mucosa, brain, andmore » cerebrospinal fluid. Silicic acidimpregnated paper chromatography of phospholipids was done using n-butyl ether, diisobutyl ketone, acetic acid, and water at room temperature. For neutron activation analysis, the paper chromatogram was sealed in an Al container. After irradiation with a slow neutro~ stream, 5 x 10/sup 11/ neutrons/cm/sup 2// sec for 15 hr (irradiation was carried out at the Research Reactor AB Atomenergi, Stockholm), autoradiograms were prepared, using a plastic sheet as a filter, and standard x-ray film. After identification, the individual phospholipids were cut from the paper chromatogram, eluted and an aliquot taken for phosphorus determination. It was possible for the first time to analyze phospholipids from samples obtained by liver biopsy, where conventional methods are not suitable since only a few mg of tissue are available. It should also be possible to apply this technique to samples obtained by percutaneous liver biopsy. In this way, changes of the phospholipid composition of human liver in comparison to that of plasma under pathological conditions could be followed. As more reactors become more available, the neutron activation paper chromatographic technique will be used more widely to make a significant contribution in the field of clinical research where only minute samples from patients are available.

  • A method for the semiquantitative microdetermination of uranium in natural waters is described. The method is based on the uv fiuorescence obtained when a salt of uranium reacts on paper with sodium triphosphate and zinc acetate. The reaction can still detect 0.001 gamma of uranium in a dilution of 1 x 10/ sup 6/ and thus is much more sensitive than the usually employed reaction with ferrocyanide. Samples of natural waters (0.4 to 10 nfl) are concentrated by evaporation onto the chromatogram. The uranium is then separated from interfering ions by ascending development with hexone-HNO/sub 3/. The time required formore » a determination depends on the concentration of uranium (concentration of sample) and is 45 minutes for >25 gamma /1 and 3 hr for >25 gamma /1. Since only a mineral light lamp and a hairdryer are used, the analysis can be carried out in the field. (auth)« less
