Última Biodistribution of 99m technetium- labeled creatinine in healthy rats BJMBR Yilmaz,O.; Yurt Lambrecht,F.; Soylu,A.; Durkan,K.; Kavukcu,S.. The distribution of creatinine, one of the toxic guanidine compounds, in various tissues has not been studied in detail by using radiolabeled creatinine. Our objective was to investigate the biodistribution of creatinine labeled with 99m technetium (99mTc) by the stannous (II) chloride method in healthy male Wistar rats. Quality controls were carried out by radio thin layer chromatography, high-performance liquid chromatography, and paper electrophoresis. The labeling yield was 85 ± 2% under optimum conditions (pH 7 and 100 µg stannous chloride). Rats (N = 12) were injected intravenously with 99mTc-creatinine and their blood and visceral organs were evaluated for 99mTc-creatinine uptake as percent of the injected dose per gram wet weight of each tissue...

Experience in inflammatory bowel disease BABT Martin-Comin,Joseph; Cardoso,Valbert Nascimento; Plaza,Pedro; Roca,Manoel. In this work Hank's balanced salt solution (HBSS) has been used, as resuspension medium, instead of leukocyte poor plasma (LPP) to label autologous white blood cells in 28 patients with suspicion af active inflammatory bowel disease.Labelled cells were reinjected and anterior and caudo-craneal views were obtained at 30 min, 2 h and 6 h p.i. Regions of interest were outlined on liver, spleen, lung, bone marrow (spine), background and lesions and the organ/background activity ratios were calculated in all scans. Patients were classified into 2 groups: Group 1: LPP, 30 patients and Groups 2: HBSS, 28 patients. Labelling efficiency was higher in HBBS group (89.0 ± 3.2 %) than in the LPP group (6.5 ± 6.3%). Organ/background activity ratios were similar in both... Tipo: Info:eu-repo/semantics/article Palavras-chave: 99mTechnetium; Leukocytes; Hank' s solution; Inflammatory.

The diagnosis of inflammatory and infectious processes is an important goal in medicine. The use of radiopharmaceuticals for identification of inflammation and infection foci has received considerable attention. The aim of this work was to evaluate the uptake and the imaging potential of stealth pH-sensitive liposomes radiolabelled with 99mTechnetium (99mTc) to identify infection sites in mice. The liposomes containing glutathione were labeled with 99mTc-Hexamethylpropyleneamine oxime (HMPAO) complex. The 99mTc-labeled stealth pH-sensitive liposomes (99mTc-SpHL) were injected in mice bearing infection in the right thigh muscle induced by Staphylococcus aureus. Biodistribution studies and scintigraphic imaging were performed at different times after...
