FIG. 3

Computed N-acetyl/Lac+Lip ratios, N-acetyl/Cho ratios, and N-acetyl/Carb ratios of MR spectra acquired on the bovine discs before (day 0) and 4 to 6 days after papain injection (day 4–6). Significant reductions of the N-acetyl/Lac+Lip ratio and the N-acetyl/Cho ratio were observed in the discs with papain injection (a), but not in the control discs. *Indicates significant statistical difference (P < 0.05).
