Abstract

To observe the influence of scalp-acupuncture on the expression of acid-sensing ion channels (ASICs) 1 a and 2 b of hippocampal CA 1 region in cerebral ischemia (CI) rats, so as to investigate its mechanism underlying improvement of ischemic stroke. Thirty-two male SD rats were randomly allocated to normal control, model, scalp-acupuncture and Amiloride group (n=8 in each group). The model of focal CI was established by middle cerebral artery occlusion (MCAO). Scalp acupuncture stimulation was applied to bilateral Dingnieqianxiexian (MS 6) and Dingniehouxiexian (MS 7), once daily for 7 days. Rats of the Amiloride group were fed with Amiloride solution, twice a day for 7 days, and those of the normal control and model groups were grabbled and fixed in the same way with the acupuncture and Amiloride groups. The neurological deficit score was given according to Longa's method. The expression of hippocampal ASIC 1 a and ASIC 2 b was detected by immunohistochemistry, and the Ca(2+) concentration in the hippocampal tissue assayed using flowing cytometry. After the intervention, the neurological deficit score of both the scalp-acupuncture and Amiloride groups were significantly decreased in comparison with pre-treatment (P<0.01), and ...Continue Reading
