title: [Measurement of human erythrocyte membrane potential with microelectrode].
abstract: The measurement of erythrocyte membrane potential (Ery-MP) in 189 healthy subjects using a microelectrode showed that the Ery-MP in 96 healthy subjects was -5.80 +/- 0.31 mV, and that in 93 healthy female subjects was -6.30 +/- 0.34 mV. Plasma lipid peroxide (P-LPO), erythrocyte lipid peroxide (Ery-LPO), plasma superoxide dismutase activity (P-SODA) and erythrocyte superoxide dismutase activity (Ery-SODA) were measured at the same time. After linear regression and correlation analysis, it was found that the Ery-MP value of healthy adults decreased as the P-LPO and Ery-LPO values increased, displaying a linear negative correlation, Ery-MP and Ery-SODA values formed a linear positive correlation.
