Figure Lengend Snippet: Effects of MK-801 on tumor necrosis factor (TNF)-α protein expression levels in the rat sciatic nerve (SN) following ischemia/reperfusion (I/R) injury. Protein expression levels of TNF-α were determined using immunohistochemistry (magnification, ×400). (A) No TNF-α expression was detected in the Schwann cells derived from the SN of a sham-operated rat. (B) Moderate protein expression levels of TNF-α were detected in the Schwann cells derived from the SN fiber of a rat in the 12 h post-reperfusion I/R subgroup. (C) Higher protein expression levels of TNF-α were detected in the Schwann cells derived from the SN of a rat in the 24 h post-reperfusion I/R subgroup. (D) Numerous inflammatory cells had infiltrated the area surrounding the Schwann cells and moderate protein expression levels of TNF-α were detected in the SN of a rat in the 72 h post-reperfusion I/R subgroup. (E) Widespread demyelination and mild-to-moderate TNF-α protein expression levels in Schwann cells were detected in the SN derived from a rat in the 7 days post-reperfusion I/R subgroup. (F) A SN from a rat in the I/R + MK-801 group at 12 h post-reperfusion exhibited mild-to-moderate TNF-α protein expression levels in Schwann cells. (G) A SN from a rat in the I/R + MK-801 group at 24 h post-reperfusion exhibited markedly fewer infiltrating cells, as compared with the SN derived from I/R rats at the same time point post-reperfusion. Moderate protein expression levels of TNF-α expression were observed. (H) A SN derived from a rat in the I/R + MK-801 group at 7 days post-reperfusion. As compared with the SNs derived from the I/R rats, the extent of demyelination was markedly reduced and Schwann cells exhibited only low protein expression levels of TNF-α.

Figure Lengend Snippet: Protein expression levels of tumor necrosis factor-α in the various treatment subgroups were quantified using the integrated optical density method, and are presented as the mean ± standard deviation (n=6). Δ P<0.05, ΔΔ P<0.01 vs. the I/R group. I/R, ischemia reperfusion.

Figure Lengend Snippet: Effects of MK-801 on TNF-α and TACE mRNA expression levels in the rat sciatic nerve (SN) following ischemia/reperfusion (I/R) injury. TNF-α and TACE mRNA expression levels were determined using reverse transcription-quantitative polymerase chain reaction and are expressed relative to β-actin. Agarose gel images showing TNF-α and TACE mRNA expression levels in the SN homogenates at (A) 0, (B) 6, (C) 12, (D) 24 and (E) 72 h and (F) 7 days post-reperfusion. β-actin=280 bp; TNF-α=402 bp; TACE=624 bp. Relative (G) TNF-α and (H) TACE mRNA expression levels are presented as the mean ± standard deviation (n=6). *P<0.05, **P<0.01 vs. the sham-operated group; Δ P<0.05, ΔΔ P<0.01 vs. the I/R group. TNF-α, tumor necrosis factor-α; TACE, TNF-α-converting enzyme.
