Due to large homology of human and canine EGFR, dogs suffering from spontaneous EGFR+ cancer can be considered as ideal translational models. Thereby, novel immunotherapeutic compounds can be developed for both human and veterinary patients. This study describes the radiolabeling of a canine anti-EGFR IgG antibody (can225IgG) with potential diagnostic and therapeutic value in comparative clinic...
introduction: clinical radiation nephropathy can result in considerable morbidity and/or mortality. renal tolerance (td5/5) has been stated to be 20 gy when irradiation has been delivered to both kidneys in 3-5 weeks. therefore to minimize renal toxicity in these patients, localization and shielding of the kidneys are essential. this study was carried out to evaluate the role of 99mtc-dtpa rena...
This study demonstrates the normal technetium-99m diethylenetriaminepentaacetic acid ([99mTc]DTPA) renal scan in pregnant patients with transplanted kidneys. Five pregnant renal transplant patients had seven [99mTc]DTPA renal studies to assess allograft perfusion and function. All scans showed the uteroplacental complex. The bladder was always compressed and distorted. The transplanted kidney w...
A three-dimensional magnetic resonance (MR) renographic method to measure single kidney glomerular filtration rate (GFR) and split renal function was developed that is based on renal signal intensity measurements during 2-3 minutes after intravenous injection of a low dose (2 mL or 0.01 mmol/kg) of gadopentetate dimeglumine. In nine subjects, single kidney MR GFR indices correlated well with te...
DTPA clearance rate is a reliable index of alveolar epithelial permeability, and is a highly sensitive marker of pulmonary epithelial damage, even of mild degree. In this study, 99mTc-DTPA aerosol inhalation scintigraphy was used to assesss the pulmonary epithelial membrane permeability and to investigate the possible application of this permeability value as an indicator of early alveolar or i...
1. The aim of the study was to examine the relationship between granulocyte activation, pulmonary intravascular granulocyte transit, pulmonary extravascular granulocyte migration and lung injury in patients with systemic conditions (bone marrow transplant recipients, inflammatory bowel disease and systemic vasculitis) in which abnormalities of pulmonary granulocyte traffic have previously been ...
Lung fluid balance is critically dependent on capillary endothelial and alveolar epithelial barrier properties, and cytoskeletal components have been implicated in these barrier functions. In an earlier study, we perfused Clostridium botulinum C2 toxin, which effects selective loss of non-muscle F-actin, through isolated rabbit lungs: a severalfold increase in the capillary filtration coefficie...
Forty-seven patients with unilateral obstructive calculi (12 males and 35 females) were submitted to 99mTc-diethylene triamine pentaacetic acid (DTPA) or 99mTc-dimercaptosuccinic acid (DMSA) scans for assessment of renal function. The scans revealed unilateral functional deficit in 68 and 66% of the patients, respectively. A calculus size of 1.1 to 2.0 cm was significantly associated with defic...
The respiratory epithelial clearance of 99mTc-(DTPA) diethylenetriamine penta-acetate (RC-DTPA) was measured in rats before and after sham or cigarette smoke exposures. RC-DTPA was increased by cigarette smoke exposure (p less than 0.001); the amount and duration of the exposure had no significant effect. In smoker animals, the number of bronchoalveolar macrophages was decreased after one or fi...
