| 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. | | | |

| 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. | | | |
