    Slow current systems in the A-V node of the rabbit heart (1980)

    Notes: [Auszug] Recently, DeMello2 reported the space constant of the rabbit A-V node as 0.4 mm. This clearly indicates that voltage-clamp studies on this tissue are possible using specimens smaller than 0.2 mm. In the present study, small A-V node specimens from the rabbit heart were prepared in essentially the ...

    Notes: Abstract By using cation-exchange membranes prepared by the paste method, a study was made of the influence of the distribution of polyvinyl chloride (PVC) on the electrical conductivity of the membranes and on the structure of the cation-exchange resin component (R-resin). Four kinds of cation-exchange membranes with different PVC contents and degrees of cross-linking were used. The experimental method involved treatment with hydrogen peroxide for selective decomposition of the R-resin. The estimated ratio of the specific electrical conductivity of the R-resin to that of the membrane varied from 2.2 to 4.4, depending upon the volume ratio of PVC in the membrane (0.33–0.45). Each of the membranes had a very high concentration of ion-exchange groups for cross-linking. This could be explained in terms of the mechanical and chemical restraint imposed by the PVC against the swelling of the R-resin. The structure of the R-resin, however, was almost independent of the PVC volume ratio over the range investigated.
