Effects of Electro-Nape Acupuncture on BAEP in Rats with Posterior Circulation Ischemia: An Experimental Study
摘要
Abstract
Objective: To observe the effect of electro-nape acupuncture on rats with posterior circulation ischemia by platform test, balance test and brainstem auditory evoked potential (BAEP) test. Methods: 90 adult male SD rats were randomly divided into the sham operation group, the model group and the electro-nape acupuncture group. The model of posterior circulation ischemia was established by electrocoagulation of vertebral arteries. The incubation period and equilibrium condition were observed before and after the treatment in each group. BAEP test was performed on the first day and the seventh day of modeling, and the amplitude (AMP) and peak latency (PL) of the Ⅰ, Ⅲ and Ⅴ waves were compared in the three groups. Results: The incubation period of the platform test was prolonged and the equilibrium was decreased obviously in the model group and the electro-nape group (P ＜ 0. 01). After 7 days of the treatment, the incubation period was shortened and the equilibrium was improved significantly in the electro-nape group compared to those of the model group (P ＜ 0. 01). BAEP test on the first day of modeling showed that AMP of Ⅲ and Ⅴ waves were obviously lower, and the PL of Ⅲ and Ⅴ waves were obviously prolonged in the model group and in the electro-nape group (P ＜0. 05); of which the sham operation group did not show obvious change (P＞ 0. 05); and Ⅰ wave showed no change. After seven days of the treatment, AMP of Ⅲ and Ⅴ waves were heightened (P ＜ 0. 05); PL of Ⅲ and Ⅴ waves were significantly shortened in the electro-nape group compared to those in the model group (P ＜0. 05); Ⅰ wave showed no obvious change (P＞ 0. 05). Conclusion: Electro-nape acupuncture can significantly improve cerebral blood circulation in rats with posterior circulation ischemia.关键词
