Figure 5From: Comparison of the vasodilator responses of isolated human and rat middle meningeal arteries to migraine related compoundsThe effect of substances on rat middle meningeal arteries precontracted with K+. The relaxation induced in rat meningeal arteries pre-contracted with K+ at increasing concentrations of each of the tested substances (A-F) and NaCl buffer (G). Values are given as mean ± SEM (n = 5), where 30 mM K+ precontraction is set to be 100%).Back to article page
