Figure 2.

Effects of PKG inhibitor, (Rp)-8-pCPT-cGMPS on the DNIC-thiosulfate-induced vascular effects in the rat tail artery. The effect of the drugs is presented as the ratio of change of [³H]noradrenaline or change in perfusion pressure evoked by S₄ over S₂. Each point represents the mean ± S.E.M. from 6–7 arteries. ^* P < 0.01 in comparison to control arteries; ^# P < 0.01 in comparison to arteries treated with DNIC-thiosulfate alone.
