Effects of Low Level Laser Irradiation on Properties of Sodium Channel in Rat Hippocampal Neurons / 生物化学与生物物理进展

0.05). - 40 mV activated threshold potential and - 30 mV peak potential for control group respectively droppedto - 60 mV and - 40 mV after irradiating 7 min. The half-activation voltage and the slope factor of the activationcurves of Na+ channel were also changed by the laser's exposure. The former changed from (- 42.091 ?1.537) mVto (54.971 ?1.846) mV (n= 8, P
