A Western blots of connexin 43 (Cx43) using a polyclonl antibody for Cx43 (Zymed Laboratories Inc, USA) in the ventricle of the rat heart. a, b and c indicate the signal before fibrillation (control), at the beginning of fibrillation and during advanced fibrillation (after 20 min), respectively. B A statistical analysis of the Western blots – a comparison of the P1 to P0 ratio among the control (a) and the two fibrillation (b and c) stages; the columns represent the relative value (1.0 is the value of the control [a]), and the vertical bars represent the mean ± SEM. *P<0.001 versus the control (a); ^†P<0.001
