Title in Portuguese
Avaliação do efeito anti-inflamatório do óxido nítrico administrado por via inalatória no modelo experimental de edema de pata induzido por carragenina em camundongos.

Óxido nítrico
Abstract in Portuguese
O Óxido Nítrico inalatório (iNO) é uitlizado para tratamento de várias doenças pulmonares, porém algumas evidências apóiam que esses efeitos farmacológicos do iNO podem alcançar outros leitos vasculares. Desse modo, esse estudo tem como objetivo investigar o possível efeito anti-inflamatório do iNO no modelo de edema de pata induzido por carragenina em camundongos e identificar por qual via ele desempenha essa resposta. Concluimos que o iNO foi eficaz na redução de sinais inflamatórios e houve indícios que o NO desempenha seus efeitos pela via do GMPc, pelo fato de ter aparecido um efeito potencializador na redução do edema quando associoado ao sildenafil e não com o rolipram. Esses resultados indicam que a terapia com iNO vai além dos efeitos vasculares pulmonares inicialmente descritos.

Abstract in English
Inhaled Nitric Oxide (iNO) is useful to treat many lung diseases, but some evidences support that these pharmacological effects of iNO can reach other vasculature, beyond the pulmonary vasculature. Thus, this study aimed to investigate the possible antiinflammatory effect of inhaled nitric oxide on the mice paw edema induced by carrageenan and investigate for which way iNO is acting. We conclude that iNO was effective in reducing inflammatory signs and there are some traces that this responses occurred by cGMP way. These results indicate that the beneficial effect of inhaled nitric oxide therapy goes beyond the initially described pulmonar vascular effects.
