Fig. 4From: Tetramethylpyrazine attenuates periorbital allodynia and neuroinflammation in a model of traumatic brain injuryTMP lowered the level of pro-inflammatory cytokines in CCI mice. CCI mice were assigned into two groups: treated with or without TMP. Tissues were collected 3 days after surgery. (a) qRT-PCR analysis of the indicated genes in microglia of CCI mice. Data were presented as ratio of the levels of indicated mRNAs to those of Actin mRNA. (b) ELISA assay of the indicated cytokines in microglia. n = 6 in each group. Data were from at least three independent experiments, and are presented as mean ± SEM values. *P < 0.05; **P < 0.01Back to article page
