人红细胞膜电位的微电极测量

Measurement of Human Erythrocyte Membrane Potential with Microelectrode

使用微电极法检测189名健康人的红细胞膜电位(Ery-MP),其中男96名,Ery-MP为-5.80±0.31mV;女93名,Ery-MP为-6.30±0.34mV。同时检测血浆、红细胞过氧化脂质和超氧化物歧化酶活性,经直线回归与相关分析发现健康成人的Ery-MP值随血浆和红细胞过氧化脂质值的升高而下降,均呈直线负相关,而Ery-MP与红细胞超氧化物歧化酶活性则呈直线正相关.

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 analysts, 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.
