OBJECTIVE The purpose of this study was to develop an imaging technique to measure and monitor tumor cells undergoing programmed death caused by radiation and chemotherapy using 99mTc-EC-annexin V. Annexin V has been used to measure programmed cell death both in vitro and in vivo. Assessment of apoptosis would be useful to evaluate the efficacy and mechanisms of therapy and disease progression ...
The myocardial uptake of technetium-99m pyrophosphate (99mTc-PYP) in perimyocarditis induced by coxsackievirus B3 in BALB/c mice was studied. 99mTc-PYP uptake ratio, measured by the ratio of counts/min per gram for the heart to counts/min per gram for the skull, began to increase 5 days after virus inoculation when myocardial necrosis was evident. On the seventh day after the inoculation, 99mTc...
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...
Bombesin (BN) is a peptide exhibiting a high affinity for the gastrin-releasing peptide (GRP) receptor, which is overexpressed by a variety of tumors, including breast or prostate cancer. The aim of the present study was the investigation of the complexes formed between a series of BN-like peptides and the nuclides (185/187)Re and 99mTc. The (185/187)Re complexes were formed via the precursor R...
Chrysobalanus icaco (abajeru; C.icaco) is recommended in the treatment of diabetes and other clinical disorders. Blood constituents labeled with technetium-99m (99mTc) are used in nuclear medicine. The aim of this study was to verify the effects of an abajeru extract on the labeling of blood constituents with 99mTc and on the shape of red blood cells (RBC). Blood samples(Wistar rats) were incub...
The differentiation of active inflammatory processes from an inactive form of the disease is of great value in the management of interstitial lung disease (ILD). The aim of this investigation was to assess the efficacy of 99mTc-methoxy-isobutyl-isonitrile (99mTc-MIBI) scans in distinguishing the severity of the disease compared to radiological and clinical parameters.In total, 19 known cases of...
OBJECTIVE The purpose of this paper is to introduce the nuclear medicine technologist to a new radiopharmaceutical, 99mTc-apcitide, for imaging acute venous thrombosis. After reading this paper, the technologist should be able to: (a) describe patient preparation for imaging with 99mTc-apcitide; (b) state the amount of 99mTc-apcitide that is administered to patients for imaging acute venous thr...
Background: Pseudomonas aeruginosa biofilm is one of the problems in antibiotic treatment infections. Nanomedicines, such as chitosan (CS) can carry multiple drugs and improve therapeutic effects antibiotics. Objectives: This study aimed at synthesis characterization ciprofloxacin-loaded nanoparticles for eradication P. aeroginosa biofilm. Methods: Cipro-CS microparticles were prepared by ionic...
Previously, technetium-99m-stannous pyrophosphate (99mTc-PPi) has been used to localize and estimate the size of myocardial infarcts in animals after permanent coronary artery occlusion. This study tested the hypothesis that 99mTc-PPi accurately sizes myocardial infarctions produced by temporary coronary artery occlusion and reflow in dogs. Three groups of dogs were studied: group A underwent 3...
