    Abstract: Disclosed herein are agents for enhancing the contrast in an ultrasound image. These agents are extremely small bubbles, or "microbubbles," comprised of specially selected gases. The microbubbles described herein exhibit long life spans in solution and may be produced at a size small enough to traverse the lungs, thus enabling improved ultrasound imaging of the cardiovascular system and other vital organs. Also disclosed herein is a method for selecting gases from which contrast agents may be produced. The method is based on calculations using inherent physical properties of gases and describes a means to associate the properties of a gas with the time for dissolution of a microbubble comprised of the gas.

    Abstract: The present invention involves a method of imaging tissue sites of inflammation which takes advantage of the up-regulation of surface antigenic markers on leukocytes upon activation thereof. A recognition agent selected from the group of chemotactic peptides, eosinophilic peptides and agents which are capable of selective interaction with a chemotactic receptor associated with activated leukocytes is radiolabeled. The radiolabeled recognition agent is infused into a patient and the patient's tissue sites are thereafter imaged in order to detect, evaluate or monitor tissue damage mediated by inflammation.

    Abstract: A method for radiolabeling a protein with a radioisotope of technetium or rhenium is disclosed which comprises the steps of contacting a solution of a protein containing a plurality of adjacent free sulfhydryl groups, or in particular cases, intact protein containing at least one disulfide group, with stannous ions, and then with radiopertechnetate or radioperrhenate, the amount of stannous ion being sufficient to substantially completely reduce the radiopertechnetate or radioperrhenate, and recovering radiolabeled protein.A rapid and quantitative method for producing a sterile, injectable solution of Tc-99m-labeled monovalent antibody fragment is also disclosed which comprises the step of mixing a sterile solution containing a monovalent antibody fragment having at least one free sulfhydryl group, stannous chloride and excess tartrate, at mildly acidic pH, or a sucrose-stabilized lyophilizate of such solution, with a sterile solution of Tc-99m-pertechnetate, whereby substantially quantitative labeling of the antibody fragment with Tc-99m is effected in about 5 minutes at ambient temperature, the resultant sterile solution of Tc-99m-labeled monovalent antibody fragment being suitable for immediate injection into a patient for scintigraphic imaging.

    Abstract: The invention relates to conjugates composed ofa) at least one polyalcohol or a derivatized polyalcohol,b) at least one active agent,c) at least one linker andd) a protein,wherein the polyalcohol(s) or the derivatized polyalcohol(s) are polyalcohols or derivatized polyalcohols which are not recognized by the defense system of an organism as exogenous, and the protein is a protein which can be taken up by the tumor specifically or non-specifically, and is not recognized by the defense system of an organism as exogenous. These conjugates are suitable for, on the one hand, making possible a very sensitive method in nuclear medicine for the diagnosis of tumors and, on the other hand, for example also offering new methods for diagnosing tumors in X-ray diagnosis, computerized tomography, nuclear spin tomography, electron spin resonance spectroscopy or electron microscopy.

    Abstract: A composition useful as an imaging agent comprises a beta adrenergic receptor antagonist compound, preferably iodopindolol, to which is covalently attached an iodine radioisotope such as .sup.123 I or .sup.124 I. This composition is used in a method for radioimaging beta adrenergic receptors in a tissue, preferably brain. In particular, the method is useful with the radioimaging technique of single photon emission computed tomography (SPECT) or positron emission tomography (PET). The above composition, as well as a kit comprising a set of one or more standard radiographic images of beta adrenergic receptors, are also useful in methods for (1) diagnosing an alteration in beta adrenergic receptors in a tissue, particularly brain; (2) diagnosing suicidal depression in a subject; and (3) detecting the therapeutic normalization of beta adrenergic receptor expression in a subject.
