Encephalopathy has been documented after administration of iopromide, (9,10) iohexol, (11) ioxilan, (4) and
metrizamide. The mechanism of neurotoxicity is unclear, but several theories have been formulated.
In 1974, this procedure was transformed with
metrizamide and years later with iohexol, both nonionic contrast agents [8].
Suspensions of liberated HSCs were prepared by centrifugation on a double-layered (17%/11.5%)
metrizamide solution (Sigma, St.

showed the correlation of surgical findings in 17 of 18 abnormal examinations and

However,

Materials: Compound 48/80, anti-DNP IgE, DNP-human serum albumin (HSA), o-phthaldialdehyde (OPA), evans blue, foetal bovine serum, [alpha]-minimum essential medium (MEM), Hank's balance salt solution (HBSS), 2,2'-Azino-bis (3 Ethylbenzthiazoline-6-sulphonic acid) tablet (ABTS) and
metrizamide (density, 1.120 g/ml) were purchased from Sigma Chemical Co.
(16-18) Iohexol is reported to be safer than
metrizamide and iopamidol for equine and canine myelography.
The partially dissociated cells were then added to Lebowitz-15 (L-15; Gibco, Grand Island, NY), defined serum-free medium and further dissociated by running the mixture through a 1 ml pipette, followed by centrifugation (400 x g for 15 min; Beckman Centrifuge) over a layer of 6.8%
metrizamide (Sigma).
