 Title    Electron Microscopic Study of the Polymyxin Treated Goat Erythrocytes  
 Abstract    Polymyxin B produced dose dependent changes in the surface topography o f the goat erythrocyte cells. Transformation from the normal biconcave discs through crenated structures to the final rounded or spherical shape was recorded by scanning electron m icroscopy. A m axim um o f three to four crenations per cell was recorded corresponding to a polym yxin dose o f 15.62 ng/ml. Transmission electron m icroscopy o f the ultrathin sections o f treated or untreated erythrocytes indicated that the crenations were formed by protrusions o f the plasma membrane, occurring presumably because o f the local increase o f m em brane fluidity after polym yxin treatment. Changes in the shape o f the erythrocytes to the ultim ate rounded forms were also indicated by the transmission electron microscopy.

 Title    Effect of Extracellular Alkali Metal Salts on the Electric Parameters of Human Erythrocytes in Normal and Pathological Conditions (Homozygous ^-Thalassemia)  
 Abstract    The conductivity of human erythrocyte cells dispersed in various uni-univalent electrolyte solutions (NaCl, KC1, LiCl, CsCl; 0.15 m) have been measured in the frequency range from 10 KHz to 100 MHz at five temperatures between 5 and 45 °C. The results were analyzed in the light of the theory of conductivity polarization of a suspension of ellipsoidal particles covered with two confocal shells. Differences in the electrical parameters of the membrane between normal and homozygous /?-thalassemic cells have been evidentiated.
