  • Title: Relationship between the tissue redox state potential and dak/dt changes of [K+]0 activity during k-strophantoside or acetylcholine induced contractures.
    Author: Wittmann I, Puppi A, Dely M.
    Journal: Acta Physiol Acad Sci Hung; 1982; 60(4):233-6. PubMed ID: 6985315.
    Abstract:
    It was established that oxidosis evoked by methylene blue during k-strophantoside and acetylcholine contractures in skeletal muscle was accompanied by an increase in the changes of [K+]0 activity, while redosis evoked by ascorbate under the same conditions was accompanied by a decrease in the changes of [K+]0 activity. These changes in [K+]0 activity parallelled the alterations of contractures caused by oxidosis or redosis suggesting that changes in the [K+]0 transient play an important role in these phenomena.
