Electroacupunture contributes to recovery of neurological deficits in experimental stroke by activating astrocytes

Restorative Neurology and Neuroscience

Abstract

Neurological deficits is one of the most prevalent clinical manifestation after stroke. The effects of astrocytes activated by electroacupunture (EA) after stroke on the neurological recovery in middle cerebral artery occlusion (MCAO) rats was not clear and definite. Our previous study showed that treatment with EA for 7 days contributed to the activation of astrocytes in MCAO rats. The purposes of this study were to 1) confirm the effects of EA for 14 days on activation of astrocytes in MCAO rats, and 2) test the relationships between activation of astrocytes and neurological functional recovery induced by EA in MCAO rats. All rats were randomly divided into five groups: naïve control group, sham control control group, MCAO, MCAO/EAn, MCAO/EAd (n = 8, for each group). Rats in MCAO/EAn group received EA treatment at acupoints of Neiguan (PC06). MCAO/EAd group received EA stimulus at acupoints of Diji (SP08). The primary indicators were locomotor recovery, histopathology, immunohistochemistry, RT-PCR and Western blot. The neurological deficit and histopathological improvements and activation of astrocytes were observed after EA treatment at acupoints PC06. Parametric correlation analyses revealed a cubic correlation relationship...Continue Reading

Acute Stroke

A stroke occurs when blood supply to the brain is interrupted depriving the brain of oxygen and nutrients. This feed focuses cerebrovascular accidents including ischemic and paralytic stroke.

Astrocytes

Astrocytes are glial cells that support the blood-brain barrier, facilitate neurotransmission, provide nutrients to neurons, and help repair damaged nervous tissues. Here is the latest research.

Astrocytes in Repair & Regeneration

Astrocytes are glial cells found within the CNS and are able to regenerate new neurons. They become activated during CNS injury and disease. The activation leads to the transcription of new genes and the repair and regeneration of neurons. Discover the latest research on astrocytes in repair and regeneration here.

Brain Ischemia

Brain ischemia is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. Discover the latest research on brain ischemia here.
