Studies have shown that electroacupuncture (EA) ameliorates learning and memory after ischemic injury. However, there have been few studies elucidating the mechanisms of EA on learning and memory in cerebral hypoperfusion. In this study, we explored the cAMP response element-binding protein (CREB) signaling pathway-mediated antiapoptotic action involved in EA-induced improvement of learning and...

Cerebral ischemia induces injury, not only in the ischemic core and surrounding penumbra tissues, but also in remote areas such as the cervical spinal cord. The aim of the present study was to determine the effects of electroacupuncture (EA) on cervical spinal cord injury following cerebral ischemia/reperfusion in stroke-prone renovascular hypertensive (RHRSP) rats. The results demonstrated tha...

Prior evidence shows that acupuncture improves symptoms in both Parkinson's disease (PD) patients and animal models. We examined the effects of high-frequency (100 Hz) electroacupuncture (EA) on behavior in a rat PD model induced by medial forebrain bundle (MFB) transection. Neurotransmitters levels in the striatum were measured using in vivo microdialysis and high performance liquid chromatogr...

for the polynomial planar vector fields with a hyperbolic or nilpotent critical point at the origin, the monodromy problem has been solved, but for the strongly degenerate critical points this problem is still open. when the critical point is monodromic, the stability problem or the center- focus problem is an open problem too. in this paper we will consider the polynomial planar vector fields ...

OBJECTIVES The main objective of this study was to evaluate the anti-depressant effects of pharmacopuncture using sumsu (Bufonis venenum). METHODS Animals were divided into three groups (control, sham, and experimental), with eight mice per group. The sham and the experimental groups were exposed to 2 hours of immobilization stress daily for 14 days. They were also injected with normal saline...

We explored the neurochemical mechanism of electroacupuncture's (EA) protective effect on brain function in focal cerebral ischemia rats, using cerebral ischemia/reperfusion rats established by the middle cerebral artery occlusion (MCAO) method. Adult male Sprague-Dawley rats were randomly divided into four groups: Sham, Sham+EA, MCAO and MCAO+EA. The rats in Sham+EA and MCAO+EA were accepted E...

Acupuncture has demonstrated the function in ameliorating depressive-like behaviors via modulating PKA/CREB signaling pathway. To further confirm the antidepressant mechanism of EA on the mitogen-activated protein kinase (MAPK) and dopaminergic synapse signaling pathways, 4 target proteins were detected based on our previous iTRAQ analysis. Rats were randomly divided into control group, model g...

Electroacupuncture (EA) has shown protective effects on cognitive decline. However, the underlying molecular mechanisms are ill-understood. The present study was undertaken to determine whether the cognitive function was ameliorated in cerebral hypoperfusion rats following EA and to investigate the role of PKA/CREB pathway. We used a rat 2-vessel occlusion (2VO) model and delivered EA at Baihui...
