Objective To observe the effect of electroacupuncture(EA) on the expression of glucose transporter-1(GLUT-1) of hippocampal microvascular endothelial cells in focal cerebral ischemia(CI) rats.Methods Sixty male Wistar rats were randomly divided into sham-operation
model and electroacupuncture(EA) groups.CI model was established by middle cerebral artery occlusion with a piece of thread embolus.EA(4 Hz/20 Hz
1 mA) was applied to bilateral "Neiguan"(PC 6) for 30 min
once daily for 15 days.GLUT-1 expression in the hippocampus was detected with immunohistochemistry and Western blot
respectively.Results After the treatment
compared with the sham-operation group
the expression of GLUT-1 in microvascular endothelial cells of the hippocampus in model group shown by both histochemical and Western blot techniques decreased apparently(P<0.05).While in comparison with model group
the expression of GLUT-1 in EA group was upregulated significantly(P<0.05).Conclusion EA of PC 6 can effectively upregulate GLUT-1 expression in the hippocampus in cerebral ischemia rats
which may contribute to its effect in improving CI by raising the glucose transportation of microvascular endothelial cells.
