[Preliminary observation on imbalance degree of impedance in extracellular fluid of cells in the twelve meridians in healthy subjects].

Objective: To calculate the imbalance degree (IBD) of left-right meridian (IBD-LRM), IBD of exterior-interior meridian (IBD-EIM) and IBD of hand-foot meridians (IBD-HFM) of impedance in extracellular fluid of cells in twelve meridians of healthy subjects, so as to provide foundation for meridian diagnosis.

Methods: A total of 31 healthy volunteers were enrolled and bioelectrical impedance spectroscopy (BIS) was applied. The constant current (from 1 to 100 kHz, 200 μA) was connected into the bilateral twelve meridians through two excitation electrodes with a distance of 10 cm.

[Comparison of Extracellular and Intracellular Fluid Distribution Between Stomach Meridian or Gallbladder Meridian and Their Neighboring Tissues of Lower Leg in Healthy Volunteers].

Objective: To compare differences of extracellular fluid impedance (Re) and intracellular fluid impedance (Ri) between the Stomach(ST) Meridian or Gallbladder(GB) Meridian and their neighboring non-meridian sites of the left lower leg at the same level, so as to explore the distribution characteristics of body fluid in the meridian.

Methods: Sixteen healthy volunteers were enrolled in the present study. The Re and Ri were detected by using Ag/AgCl electrodes and a digital lock-in amplifier.

San-Ao Decoction () Regulates Urine Volume on Bronchial Asthma Model Mice.

Objective: To observe the effect of San-Ao Decoction (, SAD) on water metabolism of bronchial asthra model mice.

Methods: Forty-five female BALB/c mice were randomly divided into control, model and SAD groups by a random number table, 15 mice in each group. A composite method with ovalbumin (OVA) sensitization and challenge was developed to establish bronchial asthma model.

Understanding Qi Running in the Meridians as Interstitial Fluid Flowing via Interstitial Space of Low Hydraulic Resistance.

Qi, blood and the meridians are fundamental concepts in Chinese medicine (CM), which are components of the human body and maintain physiological function. Pathological changes of qi, blood and meridians may lead to discomfort and disease. Treatment with acupuncture or herbal medicine aims to regulate qi and blood so as to recover normal function of the meridians.

[Preliminary Observation on Imbalance Degree of Blood Perfusion on the Twelve -source Points in Healthy Subjects].

Objective: To lay a foundation for meridian diagnosis by measuring the blood perfusion (BP) on -source points of twelve meridians and calculating the normal range of imbalance degree (IBD) of left and right meridian (IBD-LRM), IBD of exterior-interior meridian (IBD-EIM) and IBD of hand-foot of the same name meridians (IBD-HFM) in healthy subjects.

Methods: BP at -source points of twelve meridians was measured on 31 healthy volunteers by a Laser Doppler Line Scanner (LDLS). BP distribution and IBD-LRM, IBD-EIM, IBD-HFM were calculated.
