Figure 4

(A) Influence of 3-[(3-cholamidopropyl) dimethylammonio]-1-propane sulfonate (CHAPS) plus methylene chloride (CH 2 Cl 2 ) fraction on contractile responses induced by phenylephrine (PE) and high potassium (KCl) and (B) the representative tracing of CHAPS plus CH 2 Cl 2 fraction effect on contractile responses induced by PE and high potassium in the isolated rat aortic strips. Other methods are the same as in Figure 3. **p < 0.01. At arrow marks, PE (10 μM) and KCl (56 mM) were added into CHAPS-pretreated aortic strips. (A) PE-induced contractile response after CH2Cl2 fraction (400 μg/mL) treatment in a CHAPS-pretreated aortic strip. (B) High KCl-induced contractile response after CH2Cl2 fraction (400 μg/mL) treatment in a CHAPS-pretreated aortic strip. The chart speed was 5 mm/min.
