Fig. 5From: Ameliorated biomechanical properties of carotid arteries by puerarin in spontaneously hypertensive ratsPUE inhibited NE-induced passive vasoconstriction. A Representative original tracings of NE- reactivity curves of SHR rats fed with PUE, PUE could obviously reduce NE-induced passive vasoconstriction as the calcium concentration increasing. B The outer diameter of carotid rings of SHR rats incubated with various concentrations of PUE, 10− 3 mol/L PUE could inhibit the outer diameter decreasing induced by increasing Ca2+Back to article page
