Figure 7 Changes of the cross-sectional areas of porcine coronary arteries three weeks after the gene transfer. The reduction of the cross-sectional area at the treated segment is expressed in percent change compared with the mean cross-sectional area of the adjacent proximal and distal normal coronary segments. EEL, external elastic lamina area; IEL, internal elastic lamina area; Lumen, lumen area; LacZ, AdCALacZ-transfected site; CNP, AdCACNP-transfected site. *p < 0.05 vs. AdCALacZ-transfected site.
