Article: Metabonomics study of the protective effects of Lonicera japonica extract on acute liver injury in dimethylnitrosamine treated rats.
[show abstract] [hide abstract]
ABSTRACT: A metabonomics approach, consisting of gas chromatography coupled to mass spectrometry (GC/MS) and a multivariate statistical technique, was developed to estimate the protective effects of Lonicera japonica extract (LJE) on acute liver injury. A high dose of dimethylnitrosamine (DMN) was used to induce an acute stage of hepatic injury in 21 male Wistar rats. The rats were divided into three groups: normal, model and treatment. Pathological changes, particularly fibrosis, were also examined by Azan staining. The results indicate that clear and consistent biochemical changes occur. Nine candidate biomarkers for DMN treatment and LJE intervention under controlled conditions were identified using chemometric analysis. Pathological analysis suggests that LJE has a protective effect to the liver. This work suggests that a metabonomics approach can be used to estimate pharmacodynamic action of naturally occurring drugs in a dynamic and non-invasive way.Journal of pharmaceutical and biomedical analysis 03/2010; 53(1):98-102. · 2.45 Impact Factor -
Article: Protective effects of Flos lonicera extract on acute liver injury by dimethylnitrosamine-induced in rats.
[show abstract] [hide abstract]
ABSTRACT: The aim of this study is to investigate effects of Flos lonicera extract (FLE) on acute liver injury model rats which induced by 35 mg/kg dimethylnitrosamine (DMN). Model rats were divided into hepatic injury control group (administrated with water), FLE group (administrated with FLE) and silymarin group (administrated with silymarin which is hepatotherapeutic drug) as positive control. They were examined including ALT, AST, ALP, gamma-GT, ALB and TP levels in serum, and MDA, GPx levels in liver tissue. In addition, pathologic changes, particularly fibrosis, were examined by Azan staining. The results revealed that the ALT, AST, ALP, gamma-GT, MDA GPx and liver fibrosis degree in the LJE group were lower than the silymarin group and control group, ALB and TP were higher than the silymarin group and control group. These results suggested that LJE may help in inhibiting of acute liver injury greater than silymarin.Journal of Natural Medicines 03/2010; 64(3):288-94. · 1.39 Impact Factor
