Figure 5: Effects of decoctions on protein levels of SUR1 (a) and Kir6.2 (b) measured by Western blot. Density values for each band were first normalized to loading control (β-actin) and then to the control group. Data are expressed as mean ± SEM (, versus control group, versus model group). DBYW: Da-Bu-Yin-Wan; QZS: Qian-Zheng-San; CD: combined decoction.
