although antidote development should proceed in an orderly fashion from observation, to experimental and safety studies, to clinical trials, this sequence is not always precisely followed. the development of fomepizole as an antidote for toxic alcohol and glycol poisoning is an example of how this may not be the case. interest in the development of fomepizole was spurred in the 1960s. shortly t...
Ethylene glycol is one of the most common toxic alcohol ingestions requiring hemodialysis for treatment. With the FDA approval in 1997 of fomepizole (4-methylpyrazole), the indications for hemodialysis in addition to fomepizole for ethylene glycol poisoning have been examined in recent articles and case reports. Fomepizole, a competitive inhibitor of alcohol dehydrogenase, binds to the same sit...
Ultraviolet–Visible (UV–Vis) spectroscopy was used, in the current investigation, to explore the dispersion and stability of titania nanoparticles in an aqueous media with different types of dispersants. Hydrochloric and nitric acids as well as ammonia were used to determine the stability of the suspension in the acidic region (pH=2.5) and basic area (pH=9.5), respectively. In addition, for mea...
An amino acid type poly(ethylene glycol) is a useful tool for preparation of a bi- or multivalent poly(ethylene glycol) hybrid of bioactive peptides, but synthesis is problematic. The amino acid type poly(ethylene glycol) was prepared from poly(oxyethylene)diglycolic acid followed by introduction of a fluorenylmethyloxycarbonyl group. The resulting product could be purified easily by LH-20 colu...
A short, monodisperse additive (octa(ethylene glycol) monophenyl ether) functions to suppress aggregation of thermally and chemically denatured lysozyme. Control studies with shorter and non-amphiphilic derivatives revealed that the amphiphilic structure is essential, and octa(ethylene glycol) is nearly the minimum chain length for amphiphilic poly(ethylene glycol)s to stabilize proteins.
As the number of patients waiting to receive transplants increases, there is a need to explore all possible donation opportunities. In this case report, we describe the transplantation of a liver from a donor who died after ethylene glycol poisoning into a woman with alcoholic liver disease with cirrhosis and associated ascites. Donor management, including ethanol, fomepizol and haemodialysis, ...
Glass transition behavior of ternary disaccharide-ethylene glycol-water solutions, in reference to that of the binary combinations, has been investigated towards a better understanding of their cryoprotective ability. In water-deficient solutions, the disaccharides, including trehalose, sucrose and maltose, can associate with more than 100 ethylene glycol molecules to form amorphous complex, on...
Ethylene glycol, a common antifreeze, coolant and industrial solvent, is responsible for many instances of accidental and intentional poisoning annually. Following ingestion, ethylene glycol is first hepatically metabolised to glycoaldehyde by alcohol dehydrogenase. Glycoaldehyde is then oxidised to glycolic acid, glyoxylic acid and finally oxalic acid. While ethylene glycol itself causes intox...
INTRODUCTION Every year about 2.4 million people in USA are exposed to toxic substances. Many of them are children below 6 years of age. Majority of poisonings in children are incidental and related to household products including for example drugs, cleaning products or antifreeze products. Antifreeze solutions contain ethylene glycol and methanol. Treatment of these toxic substances involves e...
BACKGROUND Increasing cell membrane permeability to water and cryoprotectants is critical for the successful cryopreservation of cells with large volumes. Artificial expression of water-selective aquaporins or aquaglyceroporins (GLPs), such as mammalian aquaporin-3 (AQP3), enhances cell permeability to water and cryoprotectants, but it is known that AQP3-mediated water and solute permeation is ...
