Results of gene expression by Semi-quantitative RT-PCR. Representative gel images of E-sel, ICAM-1, VCAM-1 and MCP- 1 mRNA expression of the second portion of rabbit aortas. β-actin was used as an internal control and PCR products were visualized by ethidium bromide staining. The data in the bar graph are quantified ratios of the signal for E-sel, ICAM-1, VCAM-1 and MCP-1 to that for β-actin with the control samples set at 100%. Results are expressed as mean± SD (n = 6). ** p <0.01 compared with the model group, ## p < 0.01, compared with control group.
