Technetium-99m-antimony trisulfide colloid ((99m)Tc-ATC) was investigated with varying specific activity in the rat lymphatic system, as well as its binding to rat blood cells in vitro. Low, moderate and high doses of (99m)Tc-ATC were subdermally injected into tails of rats (n=3) and 30min later whole body lymphoscintigraphic images were acquired. (99m)Tc-ATC was incubated for 30min at 37°C wit...

introduction: many radiotracers have been used for sentinel node mapping with acceptable results. the main difference between these radiotracers is the particle size. in the current study, we reported defective labeling of tc-99m antimony sulfide colloid which resulted in large particle size. methods: tc-99m-antimony sulfide colloid was used for axillary sentinel node mapping of 45 breast cance...

The basic sensitivity of the Limulus test and the inhibitory factors were examined in 21 radiopharmaceuticals commonly used in Japan. The sensitivity of the Limulus test using pre-gel was found to be 1 mug/ml for Escherichia coli endotoxin. This sensitivity is about ten times that of the rabbit test adopted by USP and JP. The Limulus test was applicable, with full sensitivity and without inhibi...

This paper presents a case of an 80-year-old man with idiopathic thrombocytopenic purpura after splenectomy performed many years ago, which normalized platelet count, presented with severe thrombocytopenia with no response to treatment. A SPECT/CT study was performed using 99mTc-labelled Sn-colloid. The histology confirmed the presence of splenic tissue in those foci. Spleen examination (SPECT/...

introduction: sentinel lymph node biopsy is the standard procedure for lymph node staging in intermediate thickness melanoma. in iran, this procedure has not been addressed sufficiently. in this study, we report our experience in this area. methods: ten consecutive patients with intermediate thickness melanoma where included in our study. 1.5 mci of tc-99m antimony sulfide colloid in two divide...

In this Letter, a dynamically tunable metasurface, which is based on antimony trisulfide, introduced. structure, first metal-insulator-metal (MIM) nanocavity optimized in way that, upon phase change, the visible response switches from transmissive colored window into reflective mirror. Later, an indium tin oxide nanoantenna integrated MIM cavity to provide antireflection short-wave infrared (SW...
