Lpa expression levels in the radial arteries were positively associated with the plasma Lpa levels. Protein expression levels of Lpa in the radial arteries were measured by (a) immunofluorescent staining (original magnification ×200) and (c) immunohistochemical staining (brown colour, original magnification × 200). The values of semiquantitative analyses of the positive areas were expressed as the mean ± SD of five patients from each group (n = 5). b 0.0284±0.0041 vs. 0.0221±0.0028. ^aP < 0.05 for the high Lpa group compared with the control, respectively. d 0.1135±0.0268 vs. 0.0709±0.0085. ^aP < 0.05 for the high Lpa group compared with the control, respectively.
