Neuroprotein changes in the spinal cord of rodents with aliphatic gamma-diketone axonopathy induced by 2,5-hexanedione (2,5-HD) are compared with those reported previously in aromatic gamma-diketone-like axonopathy induced by 1,2-diacetylbenzene (1,2-DAB). Sprague-Dawley rats were treated intraperitoneally with 500 mg/kg/day 2,5-HD, equimolar

The aromatic gamma-diketone 1,2-diacetylbenzene (1,2-DAB), the putative active metabolite of the organic solvent 1,2-diethylbenzene, forms blue-colored polymeric protein adducts and induces the formation of amyotrophic lateral sclerosis (ALS)-like giant, intraspinal neurofilamentous axonal swellings in Sprague Dawley rats. The pathogenetic mechanism

Organic solvents are ubiquitous in industrial and household surroundings, and thus individuals are easily exposed. 1,2-Diethylbenzene (DEB) is one of organic solvents contained in gasoline or jet fuels. DEB is absorbed by dermal or inhalation routes, metabolized by cytochrome P-450

Environmental substances or metabolites induce neuronal damage through oxidative stress. Environmental organic solvent metabolite, 1,2-diacetylbenzene (1,2-DAB), treated rats develop limb weakness with neuropathological damage in both the central and peripheral nervous systems. In this experiment, we examined the relevance of

1,2-Diacetylbenzene (DAB) is a neurotoxic minor metabolite of 1,2-diethylbenzene or naphthalene reaction product with OH radical. DAB causes central and peripheral neuropathies that lead to motor neuronal deficits. However, the potent effects and molecular mechanisms of DAB on neural progenitor
