Participation of reactive oxygen species in regulation of Са2+ - activated К + channels of erythrocytes

open access: yesБюллетень сибирской медицины, 2009
In this study, we investigated the effects of preincubation with the reactive oxygen species-generating system xanthine oxidase/xanthine on Ca2+-dependent potassium permeability of erythrocyte membrane. The increase of intracellular calcium concentration
