ABSTRACT
Objective:
To investigate the effect and mechanism of Xiaoyaosan on lipopolysaccharide(LPS)-induced nerve injury.Method:
The 56 rats were randomly divided into control group, sham group, model group, amitriptyline group (10 mg·kg-1), fluoxetine group (10 mg·kg-1), Xiaoyaosan group high and low-dose (30,15 g·kg-1).The nerve injury model rat were established by LPS injection into lateral ventride, rats were administrated for 14 days by gavage. The levels of brain-derived neurotrophic factor (BDNF) and β-nerve growth factor (β-NGF) in serum were detected by enzyme linked immunosorbent assay(ELISA), and the expressions of BDNF, nerve growth factor (NGF), tropomyosin receptor kinase B (TrkB), tropomyosin receptor kinase A (TrkA), cAMP response element-binding protein (CREB) mRNA in hippocampus and cortex were detected by Real-time PCR.Protoin expression of BDNF, TrkB, CREB, p-CREB, postsynaptic density protein 95 (PSD95), synaptophysin (SYP) in hippocampus and cortex were detected by Western blot.Result:
Compared with control group, LPS decreased the level of BDNF and β-NGF in serum(PPPβ-NGF in serum in Xiaoyaosan high and low-dose group were increased significantly (PPPPConclusion:
Xiaoyaosan has a certain antagonistic effect on LPS inducednerve injury, which suggests that the effect is related to activate BDNF/NGF-TrkB/TrkA-CREB pathway and upregulated the expression of synaptic protein.
