RESUMO
Objective To investigate the liver protective effects of Xiaoyaosan in carbon tetrachloride-induced acute liver injury in mice.Methods Thirty mice were randomly divided into a control group, a model group, and aXiaoyaosan group, with 10 mice in each group. The mice in theXiaoyaosan group were intragastrically administrated withXiaoyaosan, the mice in the remaining two groups were fed with an equal volume of distilled water. After 7 days, acute liver injury were inducedvia intraperitoneal injection of carbon tetrachloride peanut oil solution. The serum levels of alanine transaminase(ALT), aspartate transaminase (AST), malondialdehyde(MDA)and superoxide dismutase(SOD)were measured, and pathological changes of liver tissue was tested after 16 hours.Results The serum levels of ALT(136.46±15.75 U/Lvs. 22.96±6.23 U/L), AST(145.37±16.39 U/Lvs. 31.89±7.26 U/L), and MDA level in the liver tissue(17.48±3.45 nmol/mgvs. 4.22±1.08 nmol/mg)in the model group were significantly higher than those in the control group(allP<0.01), SOD level in the liver tissue significantly lower than that in the control group(261.60±20.29 U/mgvs. 336.73±25.34 U/mg,P<0.01). The serum levels of ALT(89.38±6.96 U/L,P<0.01), AST(119.04±20.44 U/L, P<0.05), MDA level(10.30±2.22 nmol/mg,P<0.01) in the liver tissue in theXiaoyaosan group levels were significantly lower than those in the model group, and SOD level(304.77±31.71 U/mg,P<0.01) in the liver tissue were significantly higher than that in the model group.ConclusionXiaoyaosan has liver protective effects in carbon tetrachloride-induced acute liver injury in mice.
RESUMO
Objective To investigate the protective role of Xiongbitong capsule against liver injury in hyperlipemic rats.Methods Sixty Wistar male rats were randomly divided into 5 groups(12 rats in each group): a blank group, a model group, a simvastatin group(10 mg/kg, 2 ml intragastric administration daily), a Xiongbitong capsule high-dose group(25 mg/kg, 2 ml intragastric administration daily), and a Xiongbitong capsule low-dose group(12.5 mg/kg, 2 ml intragastric administration daily). Hyperlipidemia model in rats was indeuced by hyperlipidemic diet. The simvastatin group was intragastric administrated with simvastatin suspension 2 ml(10 mg/kg daily), and the rats in the control group and the model group were intragastric administrated with equal volume of saline. After 10 weeks, the serum leves of total cholesterol(TC), triacylglycerol(TG), low-density lipoprotein cholesterol(LDL-C), high-density lipoprotein cholesterol (HDL-C), nitric oxide(NO), endothelin1(ET-1), and the whole blood viscosities(high-, medium-, low-shear)were measured. Liver injury were evaluated with histopathologic examination by H.E. staining. The expressions of intercellular adhesion molecule-1(ICAM-1), monocyte chemoattractant protein-1(MCP-1)in hepatic tissue were measured by immunohistochemical staining.Results The serum leves of TC(1.47± 0.10 mmol/Lvs. 3.48±0.19 mmol/L), TG(0.38±0.11 mmol/Lvs. 0.95±0.14 mmol/L), LDL-C(1.48± 0.18 mmol/Lvs. 2.39±0.22 mmol/L), ET-1(145.81±18.65 pg/mlvs. 177.70±17.70 pg/ml) in the Xiongbitong capsule high-dose group were significantly lower than those in the model group(allP<0.01), HDL-C(1.21±0.14 mmol/Lvs. 0.65±0.10 mmol/L)and NO(31.28±2.36μmol/Lvs. 19.61±1.28μmol/L) significantly lower than those in the model group(allP<0.01), the expressions of ICAM-1(0.133±0.019vs. 0.187±0.011)and MCP-1(0.153±0.014vs. 0.264±0.020)significantly lower than those in the model group(allP<0.01). The liver injury in the Xiongbitong capsule high-dose group decreased than that in the model group. Conclusions Xiongbitong capsule can protect against liver injury via regulating lipid metabolism, protecting endothelial function and down regulating expressions of MCP-1 and ICAM-1.
RESUMO
Objective To investigate the liver protective effects of Siphonostegia chinensis decoction in rats with liver fibrosis induced by carbon tetrachloride(CCl4).Methods A total of 120 male SD rats were randomly divided into six groups: a blank control group, a model group, a Siphonostegia chinensis decoction group, a Salvia miltiorrhiza decoction group, a Rhizoma polygoni cuspidati decoction group and a polyene phosphatidylcholine capsules group, with 20 rats in each group. The model of liver fibrosis in rats was induced by subcutaneous injection with CCl4, except the blank group. Except rats in the blank control group and the model group, the rats in the other four groups were treated with Siphonostegia chinensis decoction, Salvia miltiorrhiza decoction, Rhizoma polygoni cuspidati decoction and polyene phosphatidylcholine capsules(10 ml/kg). The serum level of tumor necrosis factor-α(TNF-α)was determined with enzyme-linked immunosorbent assay, the fibrosis stage assessment were determined by histopathological examination.Results Compared with the model group, Siphonostegia chinensis decoction group significantly reduced the stage of liver fibrosis(P0.05).Compared with liver fibrosis model group(368.06±24.90)U/L, the serum level of TNF-α in the Siphonostegia chinensis decoction group(336.61± 20.20)U/L significantly reduced(P0.05).Conclusion Siphonostegia chinensis decoction has certain liver protective effect in rats with liver fibrosis induced by CCl4.
