    Abstract: The invention relates to a metal-radionuclide-labelled particulate composition which may be used in the form of a dry aerosol for lung scintigraphy, in particular, for the examination of the mucociliary transport, or for radiotherapy. The composition comprises radioactive labelled particles on a base of silica gel, another silicaceous material or a non-swelling polymer, at the surface of which organic ligands are bound covalently which comprise thiol-, amino-, alkylamino-, oxime-, dithiocarbamate-, xanthate-, thiosemicarbazone-, or dithiosemicarbazone groups or combinations thereof.The invention further relates to a method of preparing the composition and to a kit for carrying out the method.

    Abstract: The invention is a novel method and kit for directly radiolabeling proteins such as antibodies or antibody fragments for diagnostic and therapeutic purposes. The method comprises incubating a protein-containing solution with a solution of sodium ascorbate; adding a required quantity of reduced radionuclide to the incubated protein. A kit is also provided wherein the protein and/or reducing agents may be in lyophilized form.

    Abstract: A diagnostric device, composition and method of diagnosing airway dysfunction in a patient is disclosed. The apparatus and method require the subjecting of a pharmaceutical acceptable radionuclide, that is the composition, to an elevated temperature in an enclosed space in the presence of either an inert gas or oxygen to produce an inhalable product. The product is inhaled by a patient. A film is located adjacent the airways enabling mapping of the deposition of the radionuclide in the airways of the patient's lungs.

    Abstract: A process for detecting a presence of steroid receptors in tissue therapeutically and for treating certian tissue, especially tissue having estrogen receptors, includes the step of treating the tissue by injection, surface application or the like, with a labeled steroid. The labeled steroid may include a moiety which is readily imageable on a gamma radiation detector, on x-ray film, on a fluoroscope, through NMR devices or the like. An especially suitable labeled steroid has been found to be 16-.sup.123 I-17-beta-estradiol having a specific activity of greater than 2,000 curies per millimole and preferably at least 5,000 curies per millimole.
