Cholecystokinin octapeptide improves cardiac function by activating cholecystokinin octapeptide receptor in endotoxic shock rats

Figure 4 Expression of CCK-A/BR and β-actin mRNA of RT-PCR in the myocardium of ES rats. (mean±SD, n = 3) ^aP<0.05 vs control, ^bP<0.01 vs control. A: Representative pictures of CCK-AR (630 bp); B: representative pictures of CCK-BR (320 bp); C: representative pictures of β-actin (420 bp). Lane 1: DNA marker, lane 2: products expressed from kidney tissue as a positive control, lane 3: products expressed from control-saline-treated, lanes 4-7: products expressed from LPS-treated at 0.5, 2, 6, and 12 h, respectively.
