Figure 4
Effects of diosgenin and Dioscorea nipponica extract on acute experimental myocardial ischemia and treatment percentage. (i) (a–e) SOD, CAT, GPx, T-AOC, and MDA serum levels. (ii) (f) Treatment percentage of assay markers for each treatment group. Normal: normal control; ISO: model group only injected with isoprenaline; POS: positive control (propranolol, 10 mg/kg); Diosgenin L, Diosgenin M, and Diosgenin H: orally given diosgenin 20, 40, and 80 mg/kg of low, medium and high dose, respectively, after ISO injection; DN extract: orally given Dioscorea nipponica extract (500 mg/kg), after ISO injection. Data are expressed as mean ± SD (). ## versus normal control; , versus ISO group.
