Abstract/OtherAbstract:
The purpose of this study was to determine whether bradykinin mediates ovalbumin-induced increase in macromolecular efflux from the nasal mucosa of ovalbumin-sensitized hamsters in vivo and, if so, whether the L-arginine/nitric oxide biosynthetic pathway transduces, in part, this response. We found that suffusion of ovalbumin onto the in situ nasal mucosa of ovalbumin-sensitized hamsters, but not of controls, elicited a significant time- and concentration-dependent increase in clearance of fluorescein isothiocyanate-labeled dextran (mol mass, 70 kDa; P < 0.05). HOE-140, but not des-Arg9,[Leu8]-bradykinin, and NG-L-arginine methyl ester (L-NAME), but not NG-D-arginine methyl ester, significantly attenuated ovalbumin-induced responses. L-Arginine, but not D-arginine, abolished the effects of L-NAME. L-NAME also significantly attenuated bradykinin-, but not adenosine-induced increase in macromolecular efflux from the in situ nasal mucosa. Overall, these data suggest that ovalbumin increases macromolecular efflux from the in situ nasal mucosa of ovalbumin-sensitized hamsters, in part, by producing bradykinin with subsequent activation of the L-arginine/ nitric oxide biosynthetic pathway.
