Negative air ions created by water shearing improve erythrocyte deformability and aerobic metabolism

摘要

To elucidate a potential mechanism by which negative air ions improve aerobic metabolism, changes in venous blood lactate levels, pH, erythrocyte deformability, and plasma superoxide dismutase activity and ceruloplasmin levels were examined during a 1-h exposure to negative air ions created by water shearing or corona discharge in nine adult healthy volunteers. The blood lactate level decreased from 1.3 ± 0.3 to 1.0 ± 0.2 mmol/l, pH increased from 7.388 ± 0.025 to 7.417 ± 0.036, and erythrocyte deformability improved from 37.0 ± 2.2 to 35.1 ± 3.0 s, expressed as the mean ± s.d., when exposed to negative air ions created by water shearing, but did not change when exposed to negative air ions created by corona discharge. Other variables did not change in either exposure. The results obtained suggest that negative air ions created by water shearing improve aerobic metabolism by improving erythrocyte deformability.
