[An experimental study on acupoint neiguan-heart short reflex]
Zhen Ci Yan Jiu = Acupuncture Research
|January 1, 1991
Summary
This study suggests acupoint Neiguan connects to the heart via a short reflex pathway. Blocking long reflex pathways confirmed Neiguan
Area of Science:
- Neuroscience
- Cardiology
- Acupuncture Research
Context:
- Afferent nerve fibers dichotomize, supplying both the pericardium and brachium in rats.
- This provides a morphological basis for short reflex pathways.
- Acute myocardial ischemia (AMI) was induced in Wistar rats.
Purpose:
- To investigate the reflex connection between acupoint Neiguan and the heart.
- To differentiate between short and long reflex pathways in cardiac response.
- To assess the effects of acupuncture at Neiguan and Zusali on physiological parameters during AMI.
Summary:
- Following anesthetization and AMI, ECG, superficial electrical resistance, and cutaneous temperature at Neiguan and Zusali were measured.
- Dorsal roots (C6-T1) were removed to eliminate long reflex pathways.
- AMI decreased Neiguan's electrical resistance and temperature (P<0.01). Acupuncture at Neiguan improved ECG, increased heart rate, and affected Neiguan's electrical resistance, while Zusali had no effect.
Impact:
- Suggests a direct short reflex connection between acupoint Neiguan and the heart.
- Provides evidence for the physiological basis of acupuncture's effect on cardiac function.
- Highlights Neiguan as a potential target for managing cardiac conditions through short reflex pathways.
