Summary of fold changes in protein expression of NOS I, NOS II or nitrotyrosine (NT; marker for peroxynitrite) or activity of PKG determined by elisa from the ventrolateral medulla obtained during phases I or II after rats had received a microinjection, bilaterally into the RVLM of Mev (10 nmol), given alone or in addition to pretreatment with K252a (1 pmol). Note that NT is presented as % relative to absorbance detected from vehicle control group. Values are mean ± SEM of triplicate analyses on samples from four to six animals in each group. *P < 0.05 versus aCSF group and #P < 0.05 versus Mev group in the Scheffé's multiple-range analysis. ND, below detection limit.
