Abstract：
:The effects of local application of a cream containing nitric oxide (NO) donors, S-nitroso-N-acetylpenicillamine (SNAP) or isosorbide dinitrate were studied in a rat model of incision pain. An incision was made in the plantar aspect of a hind paw and the cream was applied inside the surgical wound. SNAP (1-10%) or isosorbide (2.5-5%) reduced the incision allodynia as measured with von Frey filaments. Higher concentrations produced a smaller or no effect, but SNAP (30%) intensified the allodynia. Allodynia was also intensified by SNAP (5% or 30%) in rats pretreated with intraplantar 1H-[1,2,4]oxadiazolo[4,3-alpha]quinoxalin-1-one (ODQ, 4 microg), a guanylate cyclase inhibitor. The effect of isosorbide (5%) was prevented by ODQ. The cream containing SNAP released 10- to 20-fold more nitrite than did isosorbide from a macrophage culture. We conclude that local application of drugs generating a low NO concentration reduces incision pain through activation of guanylate cyclase. Drugs generating high NO concentrations, however, intensify pain via a guanylate cyclase-independent mechanism.
