Figure 6

Immunohistochemical analysis of IL-1β and TNF-α. (a) Representative images of IL-1β staining. (b) Semiquantitative analysis of IL-1β. (c) Representative images of TNF-α staining. (d) Semiquantitative analysis of TNF-α. Significant increase in IL-1β and TNF-α level in the IDD group was observed. However, this increase was significantly downregulated by Danshen treatment. The values are expressed as the . . IDD: intervertebral disc degeneration; IVD: intervertebral disc; NP: nucleus pulposus; AF: annulus fibrosus; COL2: collagen II; MMP-3: matrix metalloproteinase-3; IL-1β: interleukin-1β; TNF-α: tumor necrosis factor-α.
