Effect of TFB on synovial apoptosis in the ankle joints of rats with AA. a Typical photographs of synovial-cell apoptosis from different groups. (a) Normal; (b) AA; (c) TFB (40 mg/kg); (d) TFB (80 mg/kg); (e) TFB (160 mg/kg); (f) GTT (10 mg/kg). b Quantitative evaluation of TUNEL-positive cells. Data are the mean ± SEM (n = 12). *p < 0.05, **p < 0.01 compared with the AA group. c Formation of DNA ladder patterns of synovial tissues in joints upon TFB treatment. (M) marker; (a) Normal; (b) AA; (c) TFB (40 mg/kg); (d) TFB (80 mg/kg); (e) TFB (160 mg/kg); (f) GTT (10 mg/kg). d Effects of TFB on expression of caspase-3 protein in synovial tissues from the ankle joints of AA rats
