  • Title: [Effect of glycerin removal on the electrical resistance of isolated muscle fiber in the frog].
    Author: Shvinka NE, Caffier G.
    Journal: Tsitologiia; 1984 May; 26(5):610-4. PubMed ID: 6332400.
    Abstract:
    Fibres isolated from iliofibularis muscles of the frog Rana esculenta were studied under current-clamp conditions with a double sucrose-gap technique. An increase of membrane resistance in muscle fibres (Rm) was demonstrated during the first 10-15 min of glycerol removal in K2SO4 solution. After a 30 min treatment in glycerol-containing K2SO4 Rm was 1.40 +/- 0.12 k omega X X cm2. The transfer of muscles from the glycerol-K2SO4 solution to an isotonic K2SO4 solution resulted in a progressive increase in the Rm which after a 15 minutes removal of glycerol reached the mean value of 2.02 +/- 0.22 k omega X cm2. It is suggested that this increase may reflect detubulation of the fibres caused by glycerol removal in muscles.
