ABSTRACT
Objective To explore the effects of electroacupuncture at Baihui (DU20) acupoint on learning and memory and its possible mechanism through the expression of brain-derived neurotrophic factor (BDNF) in APP/PS1 double-transgenic mice. Methods 30 female APP/PS1 double transgenic mice were randomly divided into model group, DU20 group and non-acupoint group, and 10 wild type mice con-sisted of wild group. DU20 group received electroacupuncture at Baihui and the non-acupoint group received electroacupuncture at non-acu-point for 28 days. Learning and memory was tested by Morris water maze. Deposition ofβ-amyloid (Aβ) peptide was determined by immu-nohistochemical staining. The expression of BDNF in cortex was examined by RT-PCR and Western blotting. Results Compared with the model group, DU20 group ameliorated the learning and memory ability of APP/PS1 double-transgenic mice (P0.05). Conclusion Electroacupuncture at DU20 acupoint could ameliorate learning and memory in APP/PS1 double-transgenic mice. The mechanism may be related to increase the expression of BDNF and decrease the deposition of Aβ.
ABSTRACT
Objective To explore the effects of electroacupuncture at Shenting (DU24) and Baihui (DU20) on learning and memory abil-ity in the cerebral ischemia-reperfusion rats and its possible mechanism. Methods 45 male Sprague-Dawley rats were randomly divided into sham group (n=15), ischemia group (n=15) and electroacupuncture group (n=15). The latter 2 groups were modeled as focal cerebral isch-emia-reperfusion injury, and the electroacupuncture group received electroacupuncture at Shenting (DU24) and Baihui (DU20) for 7 days. They were tested with Morris Water Maze, observed with Nissl's staining. The protein expression of RhoA was detected with Western blot-ting. Results The learning and memory ability improved in the electroacupuncture group (P<0.05), the injury of the neurons reduced (P<0.05) and the expression of RhoA in hippocampus decreased compared with the ischemia group (P<0.05). Conclusion Electroacupuncture could ameliorate the learning and memory ability in ischemia-reperfusion rats, which may relate with the inhibition of the expression of RhoA in hippocampus.
