Effects ofPolygonum multiflorum Thunb. water extraction by different processed temperature on acute liver injury induced by CCl4 in mice

Objective To explore the effects ofPolygonum multiflorum Thunb. by different processed temperature on acute liver injury induced by CCl4 in mice. MethodsA total of 140 KM mice were randomly divided into the control group, the positive drug group, the model group, the 100℃, 110℃, and 120℃ processed group and crude drug group, all the groups above were in sequence given the equal normal saline, silymarin (10 mg/kg), 100℃ extract (100 mg/kg), 110℃ extract (100 mg/kg), 120℃ extract (100 mg/kg) and crude drug extract (100 mg/kg) each day, respectively. After 7 days, apart of the control group, the other groups were established the acute liver injury model by the carbon tetrachloride. The blood and liver of mice were taken after 24 h post-model made. The levels of AST, ALT, Alb, TP, IL-6, TNF-a, IL-1, SOD, MDA and GSH-Px were detected, and liver pathological features of each group were observed.Results Compared with the model group, the levels of ALT (132.14 ± 19.66 U/L, 81.55 ± 12.67 U/L, 169.37 ± 24.18 U/Lvs. 261.84 ± 31.61 U/L), AST (231.57 ± 38.38 U/L, 181.73 ± 36.52 U/L, 318.36 ± 39.68 U/Lvs. 624.79 ± 49.98 U/L), IL-6 (10.35 ± 1.62 pg/ml, 6.26 ± 1.36 pg/ml, 12.57 ± 1.88 pg/mlvs. 18.73 ± 5.54 pg/ml), TNF-α (243.74 ± 13.02 pg/ml, 189.36 ± 9.85 pg/ml, 273.13 ± 14.64 pg/mlvs. 314.36 ± 29.67 pg/ml), IL-1 (235.36 ± 30.14 pg/ml, 208.07 ± 9.33 pg/ml, 48.21 ± 33.15 pg/mlvs.264.76 ± 32.55 pg/ml) in the 100℃, 110℃, 120℃ group significantly decreased (P<0.05). The levels of TP (69.16 ± 2.96 g/L, 74.14 ± 3.17 g/L, 65.73 ± 2.22 g/Lvs. 62.06 ± 2.65 g/L), Alb (35.86 ± 2.64 g/L, 36.67 ± 2.81 g/L, 34.06 ± 2.64 g/Lvs. 32.16 ± 2.05 g/L) in the 100℃, 110℃, and 120℃ group significantly increased (P<0.05). The levels of SOD (82.94 ± 6.21 U/mg, 101.33 ± 9.16 U/mg, 71.32 ± 5.15 U/mg vs. 66.22 ± 1.13 U/mg), GSH-Px (153.39 ± 15.23 U, 199.25 ± 12.04 U, 159.26 ± 17.18 Uvs. 64.79 ± 32.56 U) in the 100℃, 110℃, and 120℃ group significantly increased (P<0.05), while the level of MDA (0.96 ± 0.22 nmol/mg, 0.69 ± 0.13 nmol/mg, 1.29 ± 0.13 nmol/mgvs.1.71 ± 0.33 nmol/mg) in the 100℃, 110℃, and 120℃ group significantly decreased (P<0.05). Conclusions Different processed temperature ofPolygonum Multiflorum Thunb. water extract on liver injury in mice caused by carbon tetrachloride is not the same. The 110℃ processed temperature showd the best liver protection.
