Stress-strain curves of the periodontal ligament obtained from transverse sections of the mesial root of rat mandibular first molars. Sections were incubated in 0, 10, 30, or 50 mg/mL of neutrophil elastase or with 50 μg/mL of neutrophil elastase +5 mM sivelestat (50S). Vertical and horizontal bars represent ±1 SD of 6 animals, reproduced from Ujiie et al. (2008) [48], by permission.
