15. Measurement of joint inflammation in rheumatoid arthritis with indium-111 chloride.
Studies in the collagen and rabbit models of arthritis have indicated that indium-111 chloride (111InCl3) scintigraphy objectively measures synovial inflammation. Indium-111 chloride scans, with imaging three days after 19 MBq intravenous injection, were performed on 21 patients with definite or classical rheumatoid arthritis (RA), all of whom were functiona

18. Detection of left atrial thrombi in man using indium-111 labelled autologous platelets.
A scintigraphic technique using indium-111 labelled platelets to detect left atrial thrombi was used in 28 patients, 14 of whom had mitral valve disease and 14 combined valve disease. Imaging was performed in the anterior, right anterior oblique (45 degrees), and left lateral views on the day of injection and thereafter at one or two day intervals for a maxi

19. Kinetics, distribution, and sites of destruction of indium-111 oxine labelled red cells in haemolytic anaemia.
The survival of red cells labelled with indium-111 oxine in the circulation was determined. In vivo distribution at equilibrium and sites of deposition at the T50In--that is, the half life of labelled red cells--were quantitated with a scintillation camera and computer assisted image analysis. Although the rate of elution. Of 111In from the red cells was hig

20. Covalent attachment of metal chelates to proteins:the stability in vivo and in vitro of the conjugate of albumin with a chelate of 111indium.
Human serum albumin has been conjugated to 1-(p-bnezenediazonium)-(ethylenedinitrilo)tetraacetic acid, a powerful chelating agent, and radioactive 111indium ions have been added specifically to the chelating groups. The product, with a specific radioactivity of about 1 mCi/mg of protein, was employed as a radiotracer in scintillation scanning studies with hu

21. Erythrocyte radiolabelling: in vitro comparison of chromium, technetium, and indium in undamaged and heat damaged cells.
The stability of the commonly used red cell radio labels chromium-51, indium-(111 or 113m), and technetium-99m, within intact red cells and stroma and their distribution within the cell were compared in undamaged and heat damaged red cells in relation to the clinical use of heat damaged cells in the assessment of splenic function. Chromium-51 labelled haemog

22. Aspirin decreases platelet uptake on Dacron vascular grafts in baboons.
The influence of a single dose of aspirin (5.4-7.4 mg/kg) on platelet uptake on 4-mm Dacron interposition grafts was studied in a baboon model using gamma camera scanning for 111-Indium labeled platelets. In vitro assessment of platelet function after aspirin administration revealed that in the baboon, as in the human, aspirin abolished arachidonic acid-indu

23. Neutrophil turnover in normal rabbit lungs.
Neutrophil turnover was studied in the blood and alveoli of normal rabbits. Blood neutrophil turnover was examined by two different methods. In the first method, donor rabbit neutrophils were labeled in vivo by injecting tritium-labeled thymidine intravenously. After 72 h recipient rabbits received blood from the donors. The decline of the specific radioacti

24. Elution of 111Indium from reticuloendothelial cells.
Measurement of isotope accumulation in an organ is often used to assess that organ's removal of blood cells labelled with the isotope. This technique is only valid if the isotope does not elute from the organ. Elution of 111In from the liver and spleen has been investigated in 14 subjects following intravenous injection of heat-damaged erythrocytes labelled
