Morphological changes of lumbar intervertebral discs. a H&E staining of intervertebral disc tissues from the three groups. R ruptured group showed the most severe degenerative changes in the NP and AF; there are more degenerative performances in the NR non-ruptured group than the NC normal control group. Magnification: NP nucleus pulpous, in the upper panel, ×100; AF annulus fibrosus, in the lower panel, ×200. b Infiltrated lymphocytes (a) and small vessels (b) can be seen in the IVD tissues from the ruptured group. All magnifications were ×200
