Acupuncture with low-frequency electrical stimulation (Acu/LFES) increases renal blood flow. Experiments were performed in the sham-treated (acupuncture needle inserted near, but not at, treatment point, without LFES) and Acu/LFES-treated mice. Renal flood flow was measured using p-aminohippuric acid (PAH) infusion during the Acu/LFES. PAH concentration was tested using a PAH colorimetric assay kit. The bar graph shows mean PAH clearance from sham and Acu/LFES groups of mice. Results are normalized to grams of body weight (bars: means ± SE; n = 12/group; *P < 0.05 vs. sham).
