摘　　要：目的:观察电针和艾灸左右"天枢"穴对大鼠胃内压的影响。方法:SD大鼠随机分为电针组和温和灸组,每组10只。对电针组大鼠电针左右"天枢"穴2 min,对艾灸组大鼠艾灸左右"天枢"穴2 min,用水囊测压技术和多导电生理系统记录干预前1 min、干预2 min期间和干预后1 min大鼠胃窦部的胃内压。结果:与干预前比较,电针或艾灸左右"天枢"穴均可以抑制胃内压(P<0. 05)。干预0~30 s、30~60 s期间,电针"天枢"穴抑制胃内压的效应明显强于艾灸"天枢"穴(P<0. 05)。干预0~30 s、30~60 s期间,电针大鼠左侧"天枢"穴降低胃内压的效应强于电针大鼠右侧"天枢"穴(P<0. 05)。艾灸左、右"天枢"穴对胃内压影响的差异无统计学意义(P>0. 05)。结论:电针"天枢"穴调节胃内压的效应强于艾灸"天枢"穴,且电针左侧"天枢"穴可能存在侧向优势。Objective To observe the effect of electroacupunctur(EA)and moxibustion of left or right"Tianshu"(ST25)on intragastric pressure(IGP)in normal rats.MethodsTwenty male SD rats were equally and randomly divided into EA group and moxibustion group. EA(2 Hz/15 Hz,2 mA)or moxibustion(46-48 ℃)was applied to unilateral ST25 for 2 min. The IGP was detected by using a pressure-transducer and an amplifier before and after EA or moxibustion.ResultsCompared with pre-intervention,the IGP was significantly decreased after EA or moxibustion stimulation of both left and right ST25(P<0. 05). The IGP levels during 0-30 s and 30-60 s of EA stimulation of both left and right ST25 were significantly lower than those of moxibustion(P<0. 05). The IGP-lowering effect of EA on the left ST25 was evidently stronger than that of the right ST25(P<0. 05),but without significant difference between the bilateral sides in moxibustion-induced IGP reduction(P>0. 05).ConclusionBoth EA and moxibustion of ST25 can lower IGP,and the effect of EA is significantly stronger than that of moxibustion in normal rats. In addition,the IGP-lowering effect of EA of the left ST25 is markedly stronger than that of the right ST25,suggesting a lateral advantage effect.
