[Comparative assessment of electroencephalographic readings and perfusion index in patients in the perioperative period and coma].

Different monitoring modes are used to estimate the depth of anesthesia. Electroencephalography (EEG) is employed as a method of an electrophysiological study of brain function both during anesthesia and at the neuroresuscitative stage and changes in the peripheral vascular bed are evaluated by means of the perfusion index (PI). The purpose of the study was to comparatively analyze the use of EEG readings and PI at different stages of surgery and in coma of various etiologies.

Intrusive growth of flax phloem fibers is of intercalary type.

Flax (Linum usitatissimum L.) phloem fibers elongate considerably during their development and intrude between existing cells. We questioned whether fiber elongation is caused by cell tip growth or intercalary growth.

[A diagnostic-therapeutic complex with changeable structure].

The paper describes the principles in the construction of diagnostic and examining complexes which record biological potentials in the frequency range of 0 to 20 kHz in real time and process them and, if required, either form the stimulating exposures or synchronize a recording process with external stimuli, as well as different purpose diagnostic and examining complexes designed by these principles. While solving different problems, the core of the complexes remains constant and only do the crate module ratio and attendant periphery change. The basic difference of the complexes is their software.
