Cinnamomi ramulus Ethanol Extract Exerts Vasorelaxation through Inhibition of Ca^𝟐+ Influx and Ca^𝟐+ Release in Rat Aorta

Figure 2

Effects of CRE on extracellular Ca²⁺ influx. White bars show the vasoconstriction effect by accumulative addition of CaCl₂ (0.3–10.0 mM, CON) and black bars (CRE) show inhibitory effects by CRE (0.1 mg/mL) pretreatment under Ca²⁺-free isotonic depolarizing solution containing 60 mM KCl. Each value is the average of four-way repeated measures. Values are mean ± SD. *𝑃<0.05, **𝑃<0.005 as compared with CON of 10 mM CaCl₂.
