    Summary Inward sodium currents were measured from voltage-clamped giant axons externally perfused with artificial seawater (ASW) solutions containing various concentrations of sodium and potassium ions. The data was analyzed under the assumption that under a constant membrane potential sodium conductance is determined by a specific ion-channel site (SIS) reaction. The sodium current density values were experessed in terms of SIS-reaction rates which were compared, by means of minimization techniques, with those computed for various saturation reaction mechanisms. The following conclusions were drawn: 1) The dependence of peak inward sodium current on external sodium and potassium concentrations can be described in terms of saturation reactions. 2) The experimental data fit well the kinetics of a positive cooperative homotropic reaction, involving at least two allosteric active sites. One of these sites may be catalytic while the other, either catalytic or regulatory. 3) The inhibitory effect of external potassium on inward sodium current, can be described by a reversible competitive or noncompetitive inhibition mechanism. The values of the dissociation constant of the inhibitor-site “complex” (K i)were found to be close to the external potassium concentration under physiological conditions.

    Notes:
    Abstract Previous studies have indicated that partially occluded arteries produce sounds due to turbulence. If these sounds from the coronary arteries could be detected externally, they would provide a simple approach to the detection of coronary artery disease. To confirm the hypothesis that coronary stenosis produces detectable acoustic correlates, sounds caused by a controlled occlusion of the femoral artery of dogs were detected and analyzed using both the fast Fourier transform (FFT) and the autoregressive (AR) methods. The femoral artery was chosen, since its size and flow approximate those of coronary arteries in humans. The poles of the AR spectra and the power ratios of different sections of the FFT and AR spectra were used to differentiate the degree of the stenosis. The results showed that high frequency acoustical power between 200 and 800 Hz is associated with the turbulence produced by the partially occluded femoral arteries of the dogs. Using the AR method, high acoustic power above 200 Hz increased when the degree of the occlusions increased. The poles and power ratios of the AR spectra differed according to the degree of stenosis. However, the high frequency acoustical power above 200 Hz did not increase above the 85% occlusion.

    Notes:
    Abstract Electric field distribution in biological systems was investigated. In the analysis both the conductive and the dielectric properties of biological systems were considered. Making use of the complex dielectric coefficient, equations which describe the electric field behavior in such media, were formulated. These equations were solved numerically for a few biological systems. The solutions show that the macroscopic field distribution, for example, the refraction of the ECG wave upon passing from one tissue into another, is mainly determined by the tissue's conductive properties (in the frequency range of 0–108 Hz). However, the microscopic field distribution around the individual cells is determined by the conductive, the dielectric or both properties, depending on the frequency. At frequencies below 104 Hz the field configuration is determined largely by the system's conductive properties. At frequencies above 107 – 108 Hz, by the dielectric properties and in the range of 104 – 106 Hz both properties affect the field distribution. In this range the field direction may be shifted by as much as 90° by relatively small frequency changes.
