E_max (%) and pEC₅₀ for relaxations by DEANO and 8-Br-cGMP of contractions induced by 50 mM K⁺ and 3 µM phenylephrine (PE)

		DEANO	8-Br-cGMP
Emax (%)	K+	54 ± 3	47 ± 13
	PE	105 ± 2***	102 ± 6***
pEC50 (–logM)	K+	6.04 ± 0.08	4.36 ± 0.29
	PE	6.68 ± 0.16***	4.65 ± 0.08

Results show mean ± SEM, n= 5 endothelium-intact segments.
