[Validation of the Acoustic Voice Quality Index in the Russian language].

The Aim: Of this study was to validate the Acoustic Voice Quality Index (AVQI) in Russian language and determine threshold values to differentiate normal and dysphonic voices in russophone population.

Materials And Methods: 41 recordings of patients with laryngeal hemiplegia and hemiparesis appeared after thyroid carcinomas' surgical treatment and laryngeal cancer from the Tomsk Cancer Research Institute were used, as well as 10 new recordings of normophonic people, composing a control group.

[Physiological properties of the vancomycin-resistant strain Staphylococcus epidermidis 33 GISK VAN(R)].

Physiological properties of a selected Staphylococcus epidermidis strain 33 GISK VAN(R) with high resistance to vancomycin, multiple resistance to various antibiotics, as well as decreased sensitivity to lysozyme, lysostaphin, and the low-molecular mass peptide warnerin were studied. The strain was characterized by a thicker cell wall, resulting in considerably decreased rates of vancomycin penetration into the cells and in limited access of the antibiotic to its targets on the bacterial membrane.

[Comparative assessment of efficacy of tissue plasminogen activator and streptokinase in the treatment of patients with acute myocardial infarction].

Aim: To compare results of treatment of patients with acute myocardial infarction with tissue plasminogen activator (TPA) and streptokinase.

Material And Methods: TPA (100 mg intravenously) and streptokinase (1500000 U intravenously) were used for thrombolytic therapy of acute myocardial infarction in 114 and 118 patients, respectively.

Results: TPA treated compared with streptokinase treated patients were characterized by less frequent serious cardiac rhythm and conduction disturbances and hypotension during thrombolysis (p<0.
