Chromosomes in acute leukemia.

The karyotype of leukemic cells of 78 acute leukemia patients (37 ANLL, 34ALL, and 7 of unknown type) was studied by means of G-banding. Chromosomal abnormalities were found in 50 patients (72%). Chromosomes 8,21,5,7,11, and 19 were preferentially involved in the abnormalities, both in ANLL and in ALL. A high incidence of the characteristic rearrangement t(8;21) was noted in AML: (in 6 of 22 AMP patients). An identical reciprocal translocation--t(4;11)--was seen in 4 out of 34 ALL patients.

[Blood coagulation system in oncological patients treated with rubomycin, adriamycin and carminomycin].

Systems of blood coagulation in patients treated with antibiotics of the anthracycline group were studied. Rubomycin was used in the treatment of patients with acute leukemia Adriamycin and carminomycin were used in the treatment of patients with solid tumors. The antibiotics affected the process of blood coagulation mainly through their cytostatic effect on thrombocytopoesis. Thrombocytopenia induced deficit of thrombocytal factors participating in the process of blood coagulation which resulted in hypocoagulation and hemorrhagic complications. The plasmic factors did not significantly change during the antibiotic therapy. A tendency to decrease in the levels of prothrombine, fibrinase and fibrinogen was noted which was possible due to an inhibitory effect of the antibiotics on the function of the reticuloendothelial tissue cells or indirectly to suppression of the tumor process. More pronounced changes in the system of blood coagulation of patients treated with rubomycin were probably associated with inferiority of the thrombocytal apparatus of the patients with acute leukemia treated with the antibiotic.

[Principles of background stimulation in the treatment of amblyopia].

Described in the paper are the results of a comparative evaluation of treatment of amblyopia by computer techniques based on the modern understanding of the mechanisms of impaired visual functions, as observed in amblyopia, comprising stimulation of different canals of the visual system, which were affected or not. Better clinical-and-functional results were fixed in patients with high amblyopia by using the "Ambcar" soft stimulating the magnocellular system by sinusoidal grates with the eyes being fixed on moving objects as well as in patients with moderate amblyopia by using the "eYe" and "Krestiki" soft tools affecting different canals of the visual system and different levels of the parvocellular system. Amblyopia should be treated with respect to individual differences between affected functions of the visual system in each patient, and a therapy method should be chosen in proportion to a disease severity.
