CP pretreatment prevents coronary venular albumin leakage. (a) Representative images of albumin leakage from coronary venules in Sham group (a1), I/R group (a2), CP 0.1+I/R group (a3), CP 0.4+I/R group (a4), and CP 0.8+I/R group (a5). Bar=100μm. (b) Statistical results of albumin leakage expressed as ratio of fluorescence intensity in interstice to that in venular lumen. Results are presented as mean ± SEM (𝑛=6). ^∗𝑃<0.05 versus Sham group, ^#𝑃<0.05 versus I/R group.
