Serial gamma camera imaging was performed in 11 patients with cutaneous T-cell lymphoma after s.c. injection between the toes of 111In-labeled T101, a pan T-cell monoclonal antibody. Two of the patients also received 111In-labeled 9.2.27, an isotype-matched control monoclonal antibody. Three doses of T101 (0.1, 0.5, and 1.0 mg), coupled with 0.5 mCi 111In, were used to measure lymph node uptake...
UNLABELLED To determine the potential of sterically stabilized liposomes to image infectious and inflammatory foci, the in vivo behavior of 111In-labeled PEGylated (coated with polyethylene glycol) liposomes was studied in a rat model. METHODS Indium-111-PEGylated lipsomes were administered intravenously to rats infected with S. aureus in the left calf muscle. The distribution of the radiolab...
Selective eosinophil recruitment into tissues is a characteristic feature of allergic diseases. Chemokines are effective leukocyte chemoattractants and may play an important role in mediating eosinophil recruitment in various allergic conditions in man. Here, we describe a novel mouse model of eosinophil recruitment in which we have compared the in vivo chemoattractant activity of different C-C...
Scintigraphic imaging of metastatic melanoma lesions requires highly tumor-specific radiolabeled compounds. Because both melanotic and amelanotic melanomas overexpress receptors for -melanocyte–stimulating hormone ( -MSH; receptor name: melanocortin type 1 receptor, or MC1R), radiolabeled -MSH analogs are potential candidates for melanoma diagnosis. The aim of this study was to develop a melano...
The pharmacokinetics and tissue distribution of the monoclonal antibody radioconjugate 111In-diethylenetriaminepentaacetic acid-KC-4G3, which is directed against a high molecular weight mucin(s) antigen expressed on the human milk fat globule and many epithelial cell membranes, were examined in BALB/c nude mice with and without xenografts of the human tumor lines ZR-75 (mammary adenocarcinoma, ...
BACKGROUND We assessed the utility of scintigraphy with indium 111-labeled polyclonal human IgG scintigraphy in patients with fever of unknown origin that fulfilled the criteria of temperature of 38.3 degrees C or more for at least 3 weeks and no diagnosis during 1 week of hospital admission. We compared the utility of this technique with results of scintigraphic techniques reported in the lite...
Purpose Radiolabeled antibodies and peptides hold promise for molecular radiotherapy but are often limited by a low payload resulting in inadequate delivery of radioactivity to tumour tissue and, therefore, modest therapeutic effect. We developed a facile synthetic method of radiolabeling indium-111 (111In) to epidermal growth factor (EGF)-gold nanoparticles (111In-EGF-Au NP) with a high payloa...
The feasibility of imaging the inflammatory response to acute transmural myocardial infarction in man using biologically active indium-111 (111In)-labeled autologous leukocytes was assessed in 36 patients. Indium-111 leukocytes (approximately 500 microCi) were injected i.v. 18-112 hours after the onset of chest pain. Cardiac imaging was performed 24 hours later with a mobile gamma camera. Twent...
UNLABELLED Indium-111-labeled human nonspecific immunoglobin G (111In-IgG) is one of the newer agents suggested for scintigraphic evaluation of infection and inflammation. In this study, the utility of this agent was studied in routine clinical practice. METHODS A dose of 75 MBq 111In labeled to 2 mg IgG (MacroScint) was administered intravenously in 226 patients with 232 possible foci of inf...
B3 is a murine monoclonal antibody (mAb) that recognizes a LewisY carbohydrate antigen present on the surface of many carcinomas. An imaging and Phase I trial was performed to study the ability of 111In-mAb B3 to image known metastasis and determine the maximum tolerated dose (MTD), dose-limiting toxicity (DLT), kinetics, and biodistribution of 90Y-mAb B3. Patients (n = 26) with advanced epithe...
