Fig. 5From: Elevated C-type natriuretic peptide elicits exercise preconditioning-induced cardioprotection against myocardial injury probably via the up-regulation of NPR-BCorrelation analysis between CNP or NPR-B in the myocardium. a Correlation in Group HE. Myocardial ischemia/hypoxia density was positively correlated with CNP immunoreactive density (R = 0.762, p < 0.05) and NPR-B immunofluorescence density (R = 0.789, p < 0.05) in Group HE. b Correlation in Group EEP+HE. Myocardial ischemia/hypoxia density was positively correlated with CNP immunoreactive density (R = 0.780, p < 0.05) and NPR-B immunofluorescence density (R = 0.827, p < 0.05) in Group EEP+HE. c Correlation in Group LEP+HE. Myocardial ischemia/hypoxia density was positively correlated with CNP immunoreactive density (R = 0.764, p < 0.05) and NPR-B immunofluorescence density (R = 0.890 p < 0.05) in Group LEP+HEBack to article page
