摘要

该文报告持续恒定地分别输注0.9％和0.8％NaCl 溶液于家兔静脉,以造成不同渗透性盐水负荷,观察到电针一侧后肢相当于“三阴交”和“照海”穴,均使低渗与等渗性盐水负荷兔的尿流量与尿Na~(+)排出量显著增加,渗透物质清除率也明显升高,但对尿Na~(+)浓度则无明显影响。切除两侧颈迷走神经或摘除两侧肾神经,均可使电针效应消失。结果表明:电针的这种效应可能由于躯体传入冲动增强了刺激心房容积感受器-肾反射中枢有关,这一设想还需要进一步研究。

Abstract

Rabbits under urethane anesthesia were infused with 0.9% or 0.8% NaCl solution at constant rate for maintaining a state of hydration. In these animals there was a steady renal excretion of water and sodium. However, after a 10-minute unilateral electroacupuncture of the points corresponding to “Sanyinjao” and “Zhaohai” in human leg as described in Chinese Traditional Medicine caused a marked increase in urine flow, urinary sodium excretion and osmolar clearance in both isotonic and hypotonic saline infused animals, but had no significant effect on urinary sodium concentration. After bilateral cervical vagotomy or denervation of bilateral renal nerves the effect of electroacupuncture mentioned above no longer appeared.

Key words: Urine flow;Sodium excretion;Osmolar clearance
