Comparison of Ca-DTPA and Zn-DTPA in Removing 234Th from the Rat

Health Physics, 1985
The relative effectiveness of Ca-DTPA and Zn-DTPA as a function of the dose, number of doses and time of their administration in removing 234Th that had been administered as the citrate or nitrate from various rat organs was investigated. With a single early treatment (1.5 min after intravenous injection of 234Th), Zn-DTPA was clearly less effective ...

Ammonium Bicarbonate‐DTPA and DTPA Extractions of Sludge‐amended Soils

Journal of Environmental Quality, 1987
AbstractA DTPA (diethylenetriaminepentaacetic acid) solution is typically used to extract sludge‐amended soils to determine the relationship between soil concentration and plant levels of certain trace elements. The objective of this study was to compare the standard DTPA soil test method with the ammonium bicarbonate (NH4HCO3)‐DTPA (AB‐DTPA) procedure

Gd-DTPA

Journal of Computer Assisted Tomography, 1994
The purpose of this study was to demonstrate that gadolinium-diethylenetriamine pentaacetic acid (Gd-DTPA) could be used as a contrast medium in CT as an alternative to iodine-based compounds.Solutions of different concentrations of Gd-DTPA and iopromide were scanned in a tissue equivalent phantom and it was shown that Gd-DTPA caused 2.5 times the ...

Comparison of Tc99m-DTPA and Indium-111 DTPA Studies of Baclofen Pump Function

Clinical Nuclear Medicine, 2004
An intrathecal drug delivery system is composed of a programmable infusion pump implanted in an abdominal subcutaneous pocket and a connecting catheter, which is inserted in the intrathecal space in the spine, usually in the thoracic or lower cervical region. Intrathecal administration of Baclofen could help reduce limb spasticity, avoiding some of the

Spectrophotometric method for the determination of a bifunctional DTPA ligand in DTPA-monoclonal antibody conjugates

Bioconjugate Chemistry, 1992
A simple spectrophotometric method was developed to quantitate micromolar concentrations of a bifunctional DTPA ligand in DTPA monoclonal antibody (mAb) conjugates. Titration of a brightly colored 1:2 yttrium (III) complex of arsenazo III with the ligand 1B4M-DTPA obeyed Beer's law over the concentration range 0-2.0 microM 1B4M-DTPA at 652 nm.

Gadolinium-DTPA in Spinal Disease

Radiologic Clinics of North America, 1988
The use of paramagnetic contrast agents, in particular, gadolinium-DTPA, holds great promise for the MR evaluation of the spine. However, because of the lack of a previous model for intravenous contrast enhancement in the spine and because of some peculiarities of enhancement of spinal lesions, close attention must be paid to the appropriate uses of ...

[Acellular vaccines (DTPa/dTpa) against whooping cough, protection duration].

Enfermedades infecciosas y microbiologia clinica, 2016
An increase in whooping cough in most of the developed countries has been detected in the last decade.To determine whether the administration of dTpa vaccine instead of DTPa fifth dose is contributing to the appearance of these cases.A descriptive study based on cases of whooping cough reported during an epidemic period in the city of Alicante in the ...

Decorporation of 241 Am in Beagles by DTPA

Radiation Research, 1975
Chelation treatments using daily subcutaneous injections of ${\rm ZnNa}_{3}\text{-}{\rm DTPA}$ were begun 2 wk after the intravenous administration of 0.3 μCi/kg241 Am citrate to six female beagles averaging 505 days of age. Retention of americium in the liver and in nonliver tissue (mainly skeleton) was followed serially in the living dogs by a ...

Factors influencing DTPA conjugation with antibodies by cyclic DTPA anhydride.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1984
Diethylenetriaminepentaacetic acid (DTPA) was conjugated with a practical concentration (300 micrograms/ml) of antibody to human albumin (Ab) and 1083 17-1A monoclonal colorectal antibody (MAb-17-1A) via an acylation reaction using cyclic DTPA anhydride (cDTPAA). The conjugation reaction was favored as pH increased.

Environmental Fate of EDTA and DTPA

1997
EDTA can be extremely persistent in WWTP and also in natural waters; DTPA seems more biodegradable. However, the biodegradability of DTPA might be of negligible significance as EDTA, and in some cases also DTPA, are generally found in the receiving waters of many industrial areas, thus being classified as one of the major organic pollutants discharged ...
