[The effect of nasal sensory nerve on the enhanced nasal blood vessel permeability caused by histamine].
The rats' nasal blood vessel permeability caused by histamine was significantly lower in the groups pretreated with dicaine or maxillary neurectomy than in the histamine control group. The rats' nasal blood vessel permeability also enhanced with the central side of maxillary nerve stimulated electrically. The latter effect could be blocked by pretreating with atropine. Combining with other experimental results, we suggest that the nasal sensory nerve joins the processes of the nasal blood vessel permeability enhancement caused by histamine.
