摘要:
A delivery apparatus for delivering various media, such as medical and/or pharmaceutical media or the like, from a delivery device, such as a syringe (12), in which the delivery pressure of the medium as it is dispensed from the delivery device (10) is automatically maintained and regulated at a pre-selected level throughout delivery of the medium from the delivery apparatus. In one embodiment, the skin temperature of the patient is also sensed (23) and the pressure of the medium being administered to the patient is further adjusted in response to the sensed skin temperature.
摘要:
A method of preparing a stable, therapeutic radiopharmaceutical composition comprised of an alpha- or beta-emitting radionuclide and a ligand by lyophilizing a solution of the complex. The radionuclide preferably has a half-life of at least twelve hours. The invention also is directed to stable lyophilized radiopharmaceutical compositions prepared by this method. The invention is particularly suited to the preparation of radionuclide-labeled antibodies in a stable form which merely requires reconstitution at the point of use.
摘要:
The invention relates to a method of preparing a metal-radionuclide-labelled protein or proteinaceous material, which is intended for diagnostic or therapeutic application, by reacting a protein or a proteinaceous material with a bifunctional agent for coupling the radionuclide to the protein or proteinaceous material, a protein conjugate being formed by reaction between bifunctional agent and free amino groups or mercapto groups in the protein or proteinaceous material, and then complexing the radionuclide with the conjugate thus formed to a radionuclide complex. The invention further relates to the labelled protein or proteinaceous material thus obtained, and to a kit for preparing a radiopharmaceutical composition, which kit comprises the above-mentioned polyfunctional agent or a protein conjugate formed by reaction of a protein or proteinaceous material with said polyfunctional agent.
摘要:
The present invention relates to a vial and stopper system for maintaining the stability of sodium hypochlorite solutions. The particular system according to the present invention is capable of maintaining sodium hypochlorite solutions for periods of greater than one year, and have been shown to be effective for periods of nearly two years.
摘要:
The invention relates to a method of preparing a radiolabeled technetium complex by bringing together a pertechnetate solution in a complex-forming reaction with a compound of general formula (I) wherein R1-R12 independently represent H, C1-C4 alkyl, a carboxy group, or carboxy (C1-C4) alkyl; or wherein R1 + R2, R3 + R4, R5 + R6, R7 + R8, R9 + R10 and R11 + R12 independently represent an oxo or imino function; and wherein: R13 is H, C1-C4 alkyl or carboxy (C1-C4) alkyl; R14 is H or NH2; n is 0, 1 or 2; A represents NH2 or SH; and B represents SH, or a group of the general formula NH-(Z-CO-NH)-mZ-COOH; said reaction performed in the presence of Sn(II) as a reducing agent, in the absence of a transfer agent, in a substantially aqueous solvent system having a pH of at least 10, and at ambient temperature. The invention further relates to a kit for performing said method.
