Quantitative analysis of FGF2, VEGFA and eNOS protein expression levels in the rat heart tissues. A Quantitative image analyses of FGF2 protein were performed based on the IOD of positive immunostaining (brown) in the heart tissues from Sham, Model and HA + GA group. B Quantitative image analyses of VEGFA protein were performed based on the IOD of positive immunostaining (brown) in the heart tissues from Sham, Model and HA + GA group. C Quantitative image analyses of eNOS protein were performed based on the IOD of positive immunostaining (brown) in the heart tissues from Sham, Model and HA + GA group. Data are presented as mean ± SD, Sham group (n = 6), Model group (n = 10), and HA + GA group (n = 10). Significant differences between treatment groups were shown as ^*P < 0.05 and ^**P < 0.01
