Figure 2

(A) Influence of methylene chloride (CH 2 Cl 2 ) fraction on phenylephrine (PE)- and high potassium (KCl)-induced contractile responses and (B) the typical tracing showing the effect of CH 2 Cl 2 fraction on PE- and high potassium (KCl)-induced contractile response in the isolated rat aortic strips. Black column and brick column denote active tension induced evoked by 10 μM PE before and after adding 400 μg/mL of CH2Cl2 fraction, respectively. Other methods are the same as in Figure 1. **p < 0.01. (A) Left: PE-induced contractile response (control); right: PE-induced contractile response in the presence of CH2Cl2 fraction (400 μg/mL). (B) Left: KCl-induced contractile response (control); right: KCl-induced contractile response in the presence of CH2Cl2 fraction (400 μg/mL). At arrow marks, the indicated doses of PE (10 μM) and KCl (56 mM) were added into the bath, respectively. The chart speed was 5 mm/min.
