[Medical and technical aspects of using respiration monitoring of patients in clinical practice].

The article shows basic technical principles that have guided the design team ofpatient's respiration monitor. A block scheme of the monitor is showed, an algorithm of its work is described. Results of patient's respiratory function monitoring in postoperative period is discussed and illustrated by characteristic episodes of breathing. Authors describe the proposed method for analyzing the dynamics of respiration in time. Lot of possible steps for the improvement of hardware-software tools of patient's respiration monitor are determined.

[The validation of the frequency of performing plasmapheresis in the treatment of bronchial asthma patients]. / Obhruntuvannia kratnosti provedennia plazmaferezu v likuvanni khvorykh na bronkhial'nu astmu.

On the basis of the analysis of plasmapheresis (PPh) influence on clinical and functional and immunological indices in 105 patients with bronchial asthma the authors have come to the conclusion that PPh effect is the number-of-procedures-dependent. The most pronounced effect occurred in those groups having been given three to five PPh procedures. The above effect begins to reveal itself during the first postoperative week but the greatest positive changes take place between the 7th and the 14th days. As it won't make any difference whether three or five PPh sessions are conducted, the authors recommend plasmapheresis to be done on a three-procedure basis.

[tRNA and aminoacyl-tRNA synthetases from the liver of rabbits in experimental myocardial infarction]. / tRNK i aminoatsil-tRNK sintetazy pecheni krolikov pri éksperimental'nom infarkte miokarda.

An acceptor activity of tRNA for glycine, glutamic acid, leucine, serine and phenylalanine was decreased in rabbit liver tissue within 6, 12 and 24 hrs after myocardial infarction; the activity was reduced within 72 hrs. Heating of tRNA under conditions of transition of biologically inactive conformations into active forms led to reduction of the acceptor activity. Contrary to tRNAs a pronounced activation of glycyl-, glutamyl-, leucyl- and phenylalanyl-tRNA synthetases was observed in liver extracts within 6, 12, 24 and 72 hrs after myocardial infarction. A correlation between the activation of these enzymes and alterations in their activity after association with high molecular complexes was found only for several aminoacyl-tRNA synthetases studied. The rate of tRNA aminoacylation specific for alanine, and alanyl-tRNA synthetase activity were unaltered within all the periods of myocardial infarction.
