Electrophysiological and histopathological evaluation of respiratory tract, diaphragm, and phrenic nerve after dichlorvos inhalation in rats.

abstract：BACKGROUND:The toxicity of multi-walled carbon nanotubes (MWCNT) may be related to the immune system. The objective of this study was to obtain information for immunotoxic mechanisms of MWCNT in situ. METHODS:Using whole-body inhalation, male and female rats were exposed to 0, 0.2, 1 or 5 mg MWCNT/m³ for 13 weeks. The...
