A thoretical consideration of the factors which influence the accumulation of radiopharmaceuticals in bone is presented. The avidity with which 99mTc-Sn-pyrophosphate and 18F fluoride are adsorbed by bone crystals has been measured in vitro and the efficiency with which these radiopharmaceuticals are extracted by normal bone has been measured in vivo. It is(More)
UNLABELLED Our goal was to design and manufacture a kit under good manufacturing practices (GMP) for the preparation of (111)In-DTPA-hEGF Injection, a novel targeted radiotherapeutic agent for advanced epidermal growth factor receptor (EGFR)-positive breast cancer. METHODS Human EGF (hEGF) was derivatized with diethylenetriaminepentaacetic acid (DTPA) and(More)
BACKGROUND Thoracic lymphatics and lymph nodes can be affected by cancer and other diseases. Micro- or nanoparticulates are used as carriers for therapeutic agents. We investigated the lymphatic distribution after intrapleural administration of three different particulates. METHODS Various micro- and nanoparticles of charcoal, polystyrene and(More)
BACKGROUND & AIMS Nonselective nonsteroidal anti-inflammatory drug (NSAID) users are at increased risk of gastrointestinal bleeding. We aimed to assess the pattern and extent of fecal blood loss (FBL) with ibuprofen, which is considered to have a favorable gastrointestinal safety profile. METHODS We conducted a post hoc analysis of 2 separate randomized,(More)
Gastrointestinal teratomas are uncommon, benign neoplasms that occur primarily in children. A retrospective review of five cases (two gastric, one pancreatic, one mesenteric, and one in the lesser omentum) is presented with emphasis on the computed tomographic and ultrasonographic appearances. Principal findings are a well-defined mass with separate cystic(More)
AIMS To investigate the correlation between chest position and the distribution of surfactant in the lungs of surfactant depleted rabbits, to corroborate current guidelines on the intratracheal instillation of exogenous surfactant in newborns. METHODS Twelve tracheotomised rabbits, depleted of pulmonary surfactant by saline bronchoalveolar lavage, were(More)
The preparation of an yttrium-90 citrate colloid is described. This formulation localizes in the synovial membrane and thereby eliminates any irradiation received by extra-articular tissues. Yttrium-90 is eluted from Sr-90 bound to a sulphonic acid ion exchange resin. The colloid is prepared using a 3:1 ratio of carrier yttrium and citrate. Contamination(More)
The pharmacokinetics of AGN 190168, a novel synthetic retinoid, and its major metabolite, AGN 190299, in rat blood after intravenous administration was investigated. Approximately 4.4 mg kg-1 (high dose) or 0.49 mg kg-1 (low dose) of AGN 190168 was administered to rats via the femoral vein. Blood was collected from the femoral artery at various time points(More)
