Abstract:
【Objective】To investigate the influence of acupuncture on the power of brain electrical activity mapping(BEAM) and hippocampal amino acid neurotransmitters in acute epilepsy rats.【Methods】Forty SD rats were randomized into groups A(normal),B(model),C(treated with acupuncture) and D(treated with sodium valproate).Group C was pretreated with acupuncture on acupoints of Dazhui and Fenglong and with needling through Ganshu toward Danshu.Group D was pretreated with sodium valproate by gastric gavage.The treatment in groups C and D lasted 3 days.Except group A,the mice in other 3 groups received intraperitoneal injection of sodium penicillin to induce acute epilepsy.Within seventy to eighty-five minutes after modeling,different frequency-band power of BEAM in rat brain middle Pz region was detected,and rats hippocampal contents of excitatory amino acids such as glutamic acid(Glu) and aspartic acid(ASP) as well as inhibitory amino acids such as gamma-aminobutyric acid(GABA),glycine(Gly),alanine(Ala) and taurine(Tau) were examined.【Results】Power of frequency band ?,?,?_1,?_2,?_1 and ?_2 in group B increased(P
