Immunohistochemical staining and IOD of Cx43 in cardiac tissues from rats of different groups at T2. (a) Group C1 and (b) group C2: the Cx43 positive particle intensively and regularly was distributed and was clustered in the intercalated disk; (c) group I/R1 and (d) group I/R2: sparsely distributed Cx43 positive particles; (e) group LX1 and (f) group LX2: Slightly decreased Cx43 positive particles, mostly still clustered in the intercalated disk. (g) For IOD of Cx43. * for comparisons of I/R1 and LX1 groups with C1 group, for comparisons of I/R2 and LX2 with C2 group; # for comparisons of LX1 group with I/R1 group, for comparisons of LX2 group with I/R2 group; Δ for comparisons of LX2 group with LX1 group.
