Abstract/OtherAbstract:
AIM: to assess NO participation and the enzymatic pathways in the production of NO and mucociliary transport, using constructive and inductive NO synthetase inhibitors, L-NAME and aminoguanidine, respectively.
MATERIALS AND METHODS: frog palates were prepared and immersed in ringer (control), L-NAME or aminoguanidine solutions. The palates were immersed in these solutions for four periods of 15 minutes. Mucociliary transport measures were carried out before and after each exposure.
RESULTS: control palates maintained stable their transportation speed. L-NAME increased, while aminoguanidine reduced mucous transportation velocity.
CONCLUSION: unspecific cNOS block with L-NAME and relatively specific iNOS block with aminoguanidine results leads us to propose that depending on the pathway, the NO can increase or reduce mucociliary transport in frog palates.
