Toluene is a neurotoxic organic solvent widely used in industry. Acute toluene administration in rats induced a significant increase in the numbers of neural cells immunostained for p75NTR in several brainstem regions, such as the raphe magnus and the nucleus of the solitary tract, as well as in the lateral reticular, gigantocellular, vestibular and ventral(More)
The photobiological effects of two monofunctional pyridopsoralens (PPs), pyrido[3,4-c]psoralen and pyrido[3,4-c]-7-methylpsoralen were studied and compared to those of 3-carbethoxypsoralen (3-CPs) and 8-methoxypsoralen (8-MOP) in a haploid wild-type strain of yeast (Saccharomyces cerevisiae). The capacity of PPs to photoinduce lethal effects in the presence(More)
