Abstract: | AIM: To observe the therapeutic effect of stachydrine hydrochloride on experimental acute cerebral infarction in rats and to explore the underlying mechanisms. METHODS: SD rats (n=75) were randomly divided into 5 groups: sham group, cerebral infarction model group, and stachydrine hydrochloride (10 mg/kg, 20 mg/kg and 40 mg/kg) treatment groups. After the establishment of cerebral infarction model, the rats were given stachydrine hydrochloride at dose of 10 mg/kg, 20 mg/kg or 40 mg/kg by gavage daily for 14 d. The impairment of neurological function in each group was scored. The cerebral infarction volume and brain water content were measured. Moreover, the protein levels of β-catenin, cyclin D1, glycogen synthase kinase 3β (GSK-3β) and p-GSK-3β in the brain tissues were detected by Western blot. RESULTS: Compared with cerebral infarction group, the score of neurological function impairment, cerebral infarction volume and brain water content were significantly decreased in stachydrine hydrochloride treatment groups. In addition, the protein levels of β-catenin, cyclin D1 and p-GSK-3β were markedly increased after stachydrine hydrochloride treatment. CONCLUSION: Stachydrine hydrochloride protects against experimental acute cerebral infarction through activation of Wnt/β-catenin signaling pathway. |
