Abstract:
Objective To explore the influence of salvianolic acid B(SalB) to blood brain‐barrier(BBB) in vitro oxygen/glu‐cose deprivation and reintroduction .Methods We used the human brain microvascular endothelial cells and C6 cells to build BBB model that in vitro ,and the models was divided into normal groups ,experiment groups ,treatment groups .The Earle′s liquid and the condition of 93% N2 ,2% O2 ,5% CO2 replaced the normal culture environment to simulate environment of oxygen /glucose depriva‐tion and reintroduction .The changes of BBB permeability was detected by the horseradish peroxidase permeability test .The tight junctions(TJs) was detected by immunofluorescence and electron microscope .Results The permeability of treatment group was significantly lower than the experiment group (P < 0 .05) ;The TJs of normal group was continuous and density ;the experiment group′s TJs was interruption and osteoporosis ;and the observation of treatment group′s TJs was between of the two group above . Conclusion The SalB can directly protect the BBB during oxygen /glucose deprivation and reintroduction ,and decrease the permea‐bility .The investigation also provided the research foundation for the SalB to protect the BBB .
