title: Possible role of nitric oxide in IgE-mediated allergic cutaneous reaction in mice.
abstract: The role of nitric oxide (NO) in the development of allergic cutaneous reactions in mice was investigated. A biphasic cutaneous reaction composed of an immediate-phase edema and a late-phase edema was evoked by epicutaneous application of 2,4-dinitrofluorobenzene on the ear of mice passively sensitized with mouse anti-dinitrophenol monoclonal IgE. Two NO synthase inhibitors, L-NG-nitroarginine methyl ester (L-NAME) and NG-monomethyl-L-arginine, significantly inhibited both phases of the IgE-mediated biphasic cutaneous reaction. Simultaneous treatment with L-arginine attenuated the inhibitory effect of L-NAME. An NO donor, 3-morpholinosydononimine-N-ethylcarbamide, caused a potent edematous reaction in the mouse ear. Furthermore, L-NAME inhibited the cutaneous reactions caused by both interleukin-1beta and tumor necrosis factor-alpha, putative mediators of the late-phase edema in the biphasic cutaneous reaction. These results indicate that a gaseous mediator, NO, participates, at least in part, in the development of ear edema in the IgE-mediated biphasic cutaneous reaction in mice.
