Acrolein, a highly reactive unsaturated aldehyde, has been shown to play a major role in the secondary injury by contributing significantly to both motor and sensory defi- cits. In particular, efforts have been made to eluddate the mechanisms of acrolein-mediated dam- age at the cellular level and the resulting paralysis and neuropathic pain. In this review, we will highlight the recent developments in the understanding of the mechanisms of acrolein in motor and sensory dysfunction in animal models of SCI. We will also discuss the therapeutic benefits of using acrolein scavengers to attenuate acrolein-mediated neuronal damage following SCI.展开更多

The results showed that, in different levels of styrene exposure groups, there is a significant association between urinary metabolites and some genotypes of styrene-metabolizing enzymes, including CYP2E1 (5-flanking region, RsaI/PstI), GSTM1(gene deletions) and EPHX1(predicted activity).展开更多
