不同时辰针刺对金黄地鼠自发活动及体温昼夜节律的影响

Effects of acupuncture at different periods on circadian rhythms of locomotor activity and core body temperature in hamsters

目的:研究针刺调整生物昼夜节律的时间规律性。方法:在子、午、卯、酉不同时辰电针金黄地鼠“肾俞”穴,运用时间生物学研究方法观察分析不同时辰针刺对动物自发活动及体温昼夜节律的不同影响。结果:对于自发活动昼夜节律,午时针刺使其节律振幅降低(P<0.05),卯时针刺使其节律峰相位迟后(P<0.05),酉时针刺使其节律峰相位超前(P<0.05);对于体温昼夜节律,卯、酉时针刺对节律峰相位有一定程度的影响,卯时针刺使峰相位迟后22.36度,酉时针刺使峰相位超前39.32度。

Objective To explore the time law of electroaeupuncture in regulation of circadian rhythms of the or- ganism. Methods Effects of electroacupuncture at ＂Shenshu＂ （BL 23） at Zi, Wu, Mao and You periods on circadian rhythms of locomotor activity and core body temperature in hamsters were observed with chronobiological research methods. Results Electroacupuncture at Wu period could decrease the amplitude of locomotor activity rhythm （P〈0. 05）, at Mao period could delay the peak phase of circadian rhythm and at You period could advance the peak phase of circadian rhythm （both P〈0. 05） ; and electroacupuncture at Mao period could delay 22. 36 de- grees and at You period advance 39.32 degrees for the rhythm peak of the circadian rhythm of core body temperature. Conclusion Acupuncture has a certain effect on circadian rhythm of locomotor activity and core body temperature.
