ABSTRACT
Objective: To explore the effects and potential mechanism of Foshou Powder on Parkinson’s disease. Methods: Reserpine was injected in KM mice to establish Parkinson’s disease model, and hypothermia and akinesia were measured to evaluate the effects of volatile oil of Angelica sinensis, Ligusticum chuanxiong and combination. The human monoamine oxidase (hMAO) activity and inhibition mode were measured by fluorescence spectrophotometry in vitro with kynuramine as the common substrate of human monoamine oxidase A (hMAO-A) and human monoamine oxidase B (hMAO-B). On this basis, the 2 × 4 factorial design was applied to research the interaction between Angelica sinensis volatile oil and Ligusticum chuanxiong volatile oil. Results: The antagonistic experiments of reserpine showed that the application of Angelica sinensis volatile oil and Ligusticum chuanxiong volatile oil significantly improved hypothermia and akinesia. Enzyme activity test revealed that volatile oil of Angelica sinensis and Ligusticum chuanxiong had competitive inhibitory effects on hMAO-A and hMAO-B, and the combination of the two substances had significant synergistic effect on the activity of both hMAO. Conclusion: Angelica sinensis and Ligusticum chuanxiong in Foshou Powder have significant synergistic effects in the prevention and treatment of Parkinson’s disease, which may be related to the inhibition of MAO activity.
ABSTRACT
Objective:To explore the effect of Angelica Sinensis Volatile Oil on the mi RNA expression profiling in myocardium tissue of the spontaneously hypertensive rats (SHRs),and to clarify the possible mechanism of Angelica Sinensis Volatile Oil.Methods:All the SHRs were divided into Angelica group,model group and captopril group,and other Wistar rats with the same age were selected as control group.The non-invasive systolic blood pressure was detected;after 4 weeks of administration,the changes of miRNA expression profiling in myocardium tissue were measured by Affymetrix miRNA 4.0 Array.KEGG analysis was used to identify the target genes. Results:Compared with control group,the systolic blood pressure of the rats in model group was significantly decreased (P < 0.05)before treatment.4 weeks after administration,compared with model group,the systolic blood pressure of the rats in Angelica group was significantly decreased (P <0.05).Compared with model group, 29 differential miRNAs of rats in Angelica group were found (P < 0.05 ), with 13 up-regulated miRNAs and 16 down-regulated miRNAs.The KEGG analysis results showed that miR-19a,let-7i,and miR-181c were related to insulin signaling pathways; let-7i, miR-181a, and miR-455 were related to VEGF signaling pathways;miR-122,miR-181a, miR-200b, miR-181c, let-7i, and miR-19a were related to apoptosis (P < 0.05 ). Conclusion:Angelica Sinensis Volatile Oil can decrease the blood pressure in SHRs and it can regulate the blood pressure by regulating the miRNA related to insulin signaling pathways and VEGF signaling pathways.
ABSTRACT
Different processed volatile oils from AS on urine metabolites of normal rats were analyzed to reveal the possible metabolic pathways. Totally 50 male Waster rats were randomly divided into normal control group, C-ASVO group, J-ASVO group, T-ASVO group and Y-ASVO group, with 10 rats in each group. The normal group was given isovolumetric 0.5% polyoxyethylene sorbitan fatty acid ester（Tween-80）, while the other groups were given 0.176 mL•kg⁻¹ different processed volatile oils from AS. Drugs were given for 3 successive days. The urine was collected at 48 h with metabolic cages. GC-MS was employed to detect the metabolic fingerprint of rat urine in different times. Principal component analysis(PCA) and orthogonal partial least-squares discriminant analysis(OPLS-DA) were adopted for a multivariate statistical analysis. Metabolites with potential differences were selected based on the results of variable importance in the projection(VIP) and t test. The metabolic pathway analysis(MetPA) database was built for different metabolites' metabolic pathways. The results showed that compared with the normal group, 31 kinds of endogenous metabolites in the different processed volatile oils from AS groups change significantly(P<0.05). And there were differences in normal rat urine metabolites among the different processed volatile oils from AS, of which the influence degree of J-ASVO was slightly stronger than C-ASVO, T-ASVO, and Y-ASVO. Therefore, the metabolism effect may be focused on energy metabolism, amino acid metabolism, fatty acid metabolism and glucose metabolism. This study focused on metabolism and mechanism of different processed volatile oils from AS, and provided new ideas for pharmacological actions of traditional Chinese medicines.
