| pubmed-article:6812649 | pubmed:abstractText | Ultrasound of 0,2 Wt/cm2 intensity affects the ionic transport across the mitochondrial membrane in vitro. In the presence of 1 mM EGTA in the incubation medium ultrasound slows down K+ exit into the external medium after the addition of an uncoupling agent (2,4-dinitrophenol). With the addition of 100 divided by 400 mM Ca2+ to the starting medium ultrasound makes the amount of Ca2+ absorbed by mitochondrial decrease and the rate of Ca2+/H+ electroneutral exchange increase. Without Ca2+ ultrasound does not influence the rate of coupled and 2,4-dinitrophenol uncoupled respiration and oxidative phosphorylation, i.e. does not produce strong functional changes. | lld:pubmed |
