Figure 4From: Low magnitude of tensile stress represses the inflammatory response at intervertebral disc in rats Both expressions of mRNA in TSNP and SNP groups tend to rise significantly compared to the sham group ( P < 0.05). On the contrary, the level of TS group did not show the significant differences (P > 0.05). Compared with the SNP group, the expression of IL-17 in TSNP group decreased significantly (P < 0.05).Back to article page
