[Photoinduced bactericidal activity of TiO2 films].

A decline in CFU of gram-positive and gram-negative bacteria on the surface of UV illuminated TiO2 films (wavelength of 380 nm) is shown. A 29, 45, and 47% decrease in bacterial viability of Staphylococcus aureus, Staphylococcus epidermidis, and Escherichia coli, respectively, was seen following a 12-min exposition. It was first discovered that the reuse of TiO2 films to test a bacterial suspension for viability removes UV-induced bactericidal activity.

[Autologous transplantation of splenic tissue after splenectomy in gunshot abdominal wounds].

Results of experimental (12) and clinical (26) observations of autotransplantation of spleen fragments into the greater omentum after splenectomy are described. Optimum sizes of the transplanted fragments of the spleen were determined. The influence of this operation on homeostasis was studied.

[Characteristics of the diagnosis and treatment of secondary pneumonia in acute leukemia].

The authors presented the results of clinical observations and autopsy findings concerning the peculiarities of the development, diagnosis and treatment of secondary pneumonia in acute leukemia with pulmonary complications. Immunological disorders in patients with pneumonia in acute leukemia (general-changes in the levels of lysozyme, complement, immunoglobulins, T-lymphocytes, lymphocyte blast-transformation reaction; local-morphological changes, changes in the content of lysozyme, acid phosphatase activity, bronchoalveolar wash-off) were shown. A study of bronchoalveolar washes-off showed a clinical efficacy of a method of endobronchial injection of leukocytic mass for pneumonia in acute leukemia.
