Our aim was to determine whether the use of three subsequent single doses (SD) of a gadolinium chelate in brain MR imaging is useful in detecting MS lesions with different patterns of enhancement.
Cell death was quantitated by measuring either the release of lactate dehydrogenase from, or the uptake of propidium iodide into, damaged and dying cells.
A gadolinium (Gd)-enhanced magnetic resonance imaging (MRI) scan was obtained at baseline in 66 patients, and 29 patients underwent repeated MRI studies.

Gadolinium, one of the rare earth elements in the transition group IIIb of the periodic table, is found throughout the earth's crust.
With intravenous injection, gadolinium is initially in the arm vein, then the pulmonary circulation, and then the arteries; eventually, it is distributed throughout the circulatory system.
Approximately 0.3 mmol/kg gadolinium is usually sufficient for an average or heavy person when imaging in the equilibrium phase.

For SLDR measurements, exponential phase cultures of human glioma U87 were exposed to continuous or split doses of ionizing radiation, with cultures held at room temperature for various time intervals between doses.
Exponential phase A549 cells were subjected to FACS analysis following treatment with MGd and 0.25 mg/mL dichlorofluorescin acetate (DCFA) or 0.5 mg/mL propidium iodide.
In the absence of MGd, there was up to a 38-fold increase in clonogenic survival when cultures were allowed to recover for 4 hr prior to subculture, relative to cells treated with trypsin immediately after irradiation (recovery factor, RF = 38).
