To observe the effect of electroacupunctur (EA) and moxibustion of left or right "Tian-shu" (ST25) on intragastric pressure (IGP) in normal rats.
Twenty 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 unilate-ral ST25 for 2 min. The IGP was detected by using a pressure-transducer and an amplifier before and after EA or moxibustion.
Compared with pre-intervention, the IGP was significantly decreased after EA or moxibustion stimulation of both left and right ST25 (<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 (<0.05). The IGP-lowering effect of EA on the left ST25 was evidently stronger than that of the right ST25 (<0.05), but without significant difference between the bilateral sides in moxibustion-induced IGP reduction (>0.05).
Both 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.
观察电针及艾灸左侧或右侧“天枢”（ST25）对正常大鼠胃内压（IGP）的影响。
将20只雄性SD大鼠平均随机分为电针组和艾灸组。对单侧ST25施加电针（2Hz/15Hz，2mA）或艾灸（46 - 48℃）2分钟。在电针或艾灸前后，使用压力传感器和放大器检测胃内压。
与干预前相比，电针或艾灸双侧ST25后胃内压均显著降低（<0.05）。电针刺激双侧ST25在0 - 30秒和30 - 60秒期间的胃内压水平显著低于艾灸（<0.05）。电针对左侧ST25的降胃内压作用明显强于右侧ST25（<0.05），但艾灸引起的双侧胃内压降低之间无显著差异（>0.05）。
ST25电针和艾灸均可降低胃内压，在正常大鼠中电针效果明显强于艾灸。此外，左侧ST25电针的降胃内压作用明显强于右侧ST25，提示存在侧优势效应。
