目的:麻醉状态下观察手针大鼠后肢足三里穴位引起的支配该穴区的特异性神经束放电以及由此诱发的相应靶器官血压波动效应。方法:将水合氯醛麻醉处理的雄性大鼠随机分为针刺组、利多卡因注射后针刺组(穴位邻近区域肌肉注射2%利多卡因后进行足三里手针刺激)并设生理盐水注射后针刺组(穴位邻近区域肌肉注射生理盐水后进行足三里手针刺激)作为对照。持续记录足三里针刺过程中大鼠右颈动脉血压变化并同时记录分析相应的神经束放电情况。结果:以一定手法手针大鼠足三里能够引起明显的特异性神经束放电并引起相应动脉血压的下降(P〈0.05),而在穴位邻近区域注射利多卡因后上述现象消失。结论:手针大鼠足三里能够诱发支配穴位的特异性外周神经放电,该神经信号可能通过躯体心血管反射参与调节体内的血压变化。  相似文献

目的:探讨针刺信息调整自主神经功能和治疗疾病的神经通路机制,揭示针刺穴位和靶组织、器官效应的相互关系。方法:以大鼠和小鼠为对象,对躯体性针刺或电刺激下的传入神经反应特征、自主神经功能调控的重要机制之一的躯体-交感反射(一种躯体-自主神经反射)、谷氨酸神经递质的中枢性调控作用以及相应靶组织和靶器官反应的研究进行了回顾和分析。结果与结论:手针或电针刺激动物后三里穴位可以诱发支配后三里穴区的传入神经放电,而直接电刺激传入神经可模拟此过程。在外周躯体传入神经如胫神经直接给予电刺激,可在支配内脏的自主神经传出神经如交感神经上反射性诱发一个电位,该过程定义为躯体-交感反射。研究显示中枢神经系统的兴奋性谷氨酸类神经递质参与了该反射的调控。另一方面,研究显示动物后三里等穴位的躯体刺激如电针刺激可抑制小鼠后肢炎症痛的躯体感觉传入和肠易激综合症大鼠的结直肠痛的内脏感觉传入,其中脊髓GABA和NMDA受体被证明分别参与了前后过程。  相似文献

目的 脊柱推拿是传统医学的治疗方法之一。根据中医学脏腑经络相关理论,观察颈部脊柱推拿对自主神经系统功能的调节作用。方法 选择成年健康男性志愿者,通过对受试者颈部进行推拿操作,包括触压双侧颈椎横突(C2-5水平)、左右旋转和扳法,以心率和心率变异性的改变为指标,观察推拿前后自主神经系统紧张性的改变。结果 对30名正常成年男性志愿者的观察结果表明,推拿后心率显著降低(R-R间期延长);时域分析中SDNN显著性增加,频域分析中总功率谱显著性增加。以上结果皆提示迷走性张力增高。结论 颈部脊柱推拿可调节自主神经系统张力,提示了针灸推拿方法治疗临床心血管疾病如心律失常的可能性。  相似文献

This study compared the effects of distilled Rehmannia glutinosa, Wild Ginseng and Astragali Radix pharmacopuncture on the autonomic nervous system and heart rate variability. The purpose of the trial was to observe the influence distilled Astragali Radix, Wild Ginseng and Rehmannia glutinosa pharmacopuncture have on the autonomic nervous system. 120 healthy male volunteers were divided into four groups, which consisted of three experimental groups and a control group. This study was a randomized, placebo-controlled, double-blind clinical trial. Volunteers in experimental groups were underwent pharmacopuncture at GB21 (Kyonjong), and volunteers in the control group were injected with normal saline at GB21 (Kyonjong). Heart rate variability was measured seven times: before and after injection, every 5 minutes for 30 minutes. The result was distilled Rehmannia glutinosa, Wild Ginseng and Astragali Radix pharmacopuncture in healthy adult males tended to activate the autonomic nervous system, particularly the sympathetic nervous system.  相似文献

This study investigates changes in autonomic nervous function through Qi-training. The power spectrum of heart rate variability (HRV) was examined in 20 sedentary healthy subjects and 20 Qi-trainees. It was found that Qi-training in healthy young subjects during controlled respiration increases the high frequency (HF) power and decreases the low frequency/high frequency (LF/HF) power ratio of HRV. These results support the hypothesis that Qi-training increases cardiac parasympathetic tone. In addition, Qi-trainees were found to have higher parasympathetic heart modulation compared with their age-matched, sedentary counterparts. This augmented HRV in Qi-trainees provides further support for long-term Qi-training as a possible non-pharmacological cardio-protective maneuver. In conclusion, Qi-training may stabilize the autonomic nervous system by modulating the parasympathetic nervous system.  相似文献

心率变异性是反映自主神经系统活性和定量评估交感神经与迷走神经张力及其平衡性的客观指标。目前国内外对针灸调节心率变异性进行了大量研究,其中多数研究认为针灸可以兴奋迷走神经,抑制交感神经,从而增强自主神经的整合功能。在今后的研究中,应从病种选择、对照设置、长时程评价等方面加以研究,以更加全面、客观地评价针刺对心率变异性的调节作用。  相似文献

Purpose To observe the curative effect of special acupuncture techniques on female urethral syndrome and its relationship with the course of treatment.Method Four abdominal and four sacral empirical points were acupunctured with special techniques and electricity. A difference in curative effect was investigated between different numbers of treatments. Results The clinical cure rate reached 15.2% just after ≤ 10 (7.3 ± 1.3) treatments. The curative effect was significantly better after 20-40 (32.1 ± 5.8) treatments than after ≤ 10 (7.3± 1.3) treatments (χ2 = 10.086, P <0.05). The clinical cure rate reached 43.5% in the former. Conclusion Special acupuncture techniques have a good clinical effect on female urethral syndrome. The curative effect improves with an increase in the number of treatments.  相似文献

ObjectiveThe primary aim of this study is to investigate the effect of application of transcutaneous electrical nerve stimulation over acupuncture points (Acu-TENS) on post-exercise blood lactate level. The secondary aim is to explore the effect of Acu-TENS on heart rate recovery and its association with autonomic nervous system.MethodsTwenty healthy subjects (mean age 26.9 ± 1.3) acting as their own controls, were randomized to receive either Acu-TENS or Placebo-TENS as the first of two intervention protocols, implemented one week apart. During Acu-TENS, subjects received 45 min TENS bilaterally over the acupoints Neiguan (PC6). Subjects receiving Placebo-TENS had identical electrode placement but with no electrical output from the TENS unit despite an active output light. Interventions were followed by a 10-min ergometer exercise at 70% age-predicted maximal heart rate. Oxygen consumption and heart rate (HR) were recorded continuously throughout exercise. Blood lactate and blood pressure were taken at 4 time points: prior to, immediately after, at 15-min after exercise, and when HR had returned to baseline values.ResultsThe post-exercise blood lactate level in the Acu-TENS group was lower than that of the placebo group by 1.12 ± 0.39 mmol/L (p = 0.01). The Acu-TENS group also had a faster return of HR to pre-exercise level compared to placebo (9.98 ± 4.54 min, p = 0.047). Heart rate variability analysis inferred reduced sympathetic modulation during exercise after Acu-TENS. There was no between-group difference in post-exercise oxygen consumption.ConclusionAcu-TENS lowered post-exercise blood lactate level and enhanced heart rate recovery after moderate exercise. The role of Acu-TENS in exercise performance and energy metabolism warrants further investigation. (ClinicalTrails.gov Identifier: NCT01102634)  相似文献

Magnetic fields are widely considered as a method of treatment to increase the therapeutic effect when applied to acupoints. Hence, this study proposes a new method which creates significant stimulation of acupoints by using weak magnetic fields. We conducted this experiment in order to confirm the effect on the activation level of the autonomic nervous system by measuring pupil sizes in cases of stimulation by using manual acupuncture and electromagnetic acupuncture (EMA) at BL15. We selected 30 Hz of biphasic wave form with 570.1 Gauss. To confirm the biopotential by the magnetic flux density occurring in EMA that affected the activation of the autonomic nervous system, we observed the biopotential induced at the upper and the mid left and right trapezius. We observed a significant decrease in pupil size only in the EMA group (p < 0.05), thus confirming that EMA decreased the pupil size through activation of the parasympathetic nerve in the autonomic nervous system. Moreover, we confirmed that the amplitude of the biopotential which was caused by 570.1 Gauss was higher than ±20 μA. Thus, we can conclude that EMA treatment successfully activates the parasympathetic nerve in the autonomic nervous system by inducing a biotransformation by the induced biopotential.  相似文献
