[Transformation and ultrastructural changes in erythrocytes in local hemolytic reactions]. / Transformatsiia i ul'trastrukturnye izmeneniia éritrotsitov v reaktsiiakh lokal'nogo gemoliza.

Human and animal cell transformation in the local autoimmune hemolysis and stimulated erythrodieresis is enhanced during plaque formation, which fact is parallelled by a growing number of local hemolysis sites and increase of these sites' area in the preparations. Echino-poikilospherocytic transformation and ultrastructural changes in the red cells in these tests are explained by enhanced synthesis of autoantibodies-hemolysins by autoplaque-forming cells, as well as by the osmotic processes and destabilization of the cellular membrane system, including the leukocytic membranes.

[Semiautomatic sharpener for microtome knives]. / Poluavtomaticheskii stanok dlia zatochki mikrotomnykh nozhei.

An electromechanical drive of the knife frame turning the machine of the model of C1310 into semiautomatic is proposed. A reversive electric motor RD-09 is used as the drive. The modified machine gives a high quality of the cutting edge of knives and excluded the constant presence of a laboratory technician.
