Figure 3 Relative expression of messenger ribonucleic acid (mRNA) from MMP-9, TIMP-1, monocyte chemoattractant protein (MCP)-1, and tumor necrosis factor (TNF-). (A) The relative expression of mRNA from MMP-9 was higher in the AF group than in the RSR group. (B) The relative expression of mRNA from MCP-1 was higher in the AF group than in the RSR group and that of the TNF- was similar in the two groups. Closed bars = AF group; open bars = RSR group. *p < 0.05, AF vs. RSR. Abbreviations as in Figure 1
