From: In vivo experimental intervertebral disc degeneration induced by bleomycin in the rhesus monkey
Bar graphs illustrating histological score and total NP GAGs between groups. (A) The histological score of the discs in the bleomycin group was significantly higher than the control groups (# P < 0.01). (B) The total GAG of NP in the bleomycin group decreased significantly compared with the control group (# P < 0.01). GAGs: Glycosaminoglycans; NP: nucleus pulposus.
