Figure 5 The results of messenger ribonucleic acid expression in wild-type mice (n = 5) and tumor necrosis factor (TNF)- knockout (KO) mice (n = 6) determined by reverse transcription and polymerase chain reaction. (A) TNF- (p = 0.007). (B) Interleukin (IL)-6 (p-values for the presence of TNF-, ischemia and their interaction are 0.118, 0.005 and 0.129, respectively). (C) intercellular adhesion molecule (ICAM)-1 (p = 0.008, 0.002 and 0.026, respectively). (D) macrophage inflammatory protein (MIP)-1 (p = 0.144, 0.037 and 0.139, respectively). (E) MIP-2 (p = 0.016, 0.006 and 0.017, respectively). (F) monocyte chemoattractant protein (MCP)-1 (p = 0.009, 0.004 and 0.019, respectively).
