Research Abstract |
The present study revealed that exposure to 1-bromopropane, an alternative to ozone-depleting solvents, suppressed neurogenesis in the dentate gyrus of adult rats and noradrenaline, glucocorticoid receptor (GR), brain-derived neurotropic factor (BDNF) are expected to be involved in suppression of the neurogenesis. Change in serotonin level was minimal compared to the decrease in noradrenaline level. Count of proliferative cell in the dentate gyrus, and the level of noradrenaline, GR or BDNF may be used as biomarkers for the toxicity of 1-bromopropane to the central nervous system.
