Effect of Xinglou Chengqi Decoction on the blood brain barrier permeability, nerve damage and neurotrophy in rats with cerebral hemorrhage

摘要

Objective: To study the effect of Xinglou Chengqi Decoction on the blood brain barrier permeability, nerve damage and neurotrophy in rats with cerebral hemorrhage. Methods: Adult male SD rats were chosen as the experimental animals and randomly divided into control group, model group and intervention group, model group were made into cerebral hemorrhage models, and intervention group were made into cerebral hemorrhage models and given intragastric administration of Xinglou Chengqi Decoction for intervention. After 14 d of intervention, the blood brain barrier permeability, the expression of apoptosis genes as well as the contents of oxidative products, inflammatory products and nerve cytokines in brain tissues were determined. Results: The blood brain barrier permeability parameter EB level in brain tissue of model group was significantly higher than that of control group, and Bax, FasL, Fas and Caspase-3 mRNA expression as well as MDA, AOPP, TNF-α, HMGB1 and MCP-1 contents in brain tissue were significantly higher than those of control group whereas BDNF, NTF, VEGF and IGF-1 contents were significantly lower than those of control group; the blood brain barrier permeability parameter EB level in brain tissue of intervention group was significantly lower than that of model group, and Bax, FasL, Fas and Caspase-3 mRNA expression as well as MDA, AOPP, TNF-α, HMGB1 and MCP-1 contents in brain tissue were significantly lower than those of model group whereas BDNF, NTF, VEGF and IGF-1 contents were significantly higher than those of model group. Conclusion: Xinglou Chengqi Decoction intervention can reduce the blood brain barrier permeability, relieve the nerve damage and improve the neurotrophy in rat model with cerebral hemorrhage.
