中枢神经系统的兴奋传递主要依靠各种神经递质

而神经递质与细胞膜上相应的受体作用时又必然有离子参与。因此在分子水平上研究痛觉机理和痛觉调整

离子的作用占有重要位置。我们对手术病人针刺Forty patients treated by thyroidectomy received superficial cervical plexus block or electric acupuncture stimulation of acupoint Hegu and Neiguan bilaterally. All patients were random divided into groups of C

A_1

A_2 and A_3 on the basis of anesthetic method. Every patients were measured their serum concentration of Na

but no difference between group A_1 and group A_2 (P

reduced because internal environment of patients were affected by the signal of acupuncture. 2

There was no addition effect for the influence of serum Ca++ when electric acupuncture stimulated points Hegu and Neiguan at the same time intravenous injected Pethedine (1.3mg/kg). 3. It probably disturbed the value of serum Ca(++) reduced because internal environment of patients were affected by the signal of acupuncture. 2

concentration when intravenous injected 5% Glucose during the operation

but it had not influence on analgesic effect. 4. Acupuncture probably made concentratration of serum Na(++) concentration when intravenous injected 5% Glucose during the operation

the real causes are worth going further into research in future.
