[Influence of chronic obstructive pulmonary disease on hospital outcomes of percutaneous coronary interventions in patients with acute coronary syndrome].

Aim: To evaluate the impact of chronic obstructive pulmonary disease (COPD) on hospital outcomes of percutaneous coronary interventions (PCI) in patients with acute coronary syndrome (ACS).

Materials And Methods: A cohort prospective study of the COPD effect on mortality and coronary microvascular obstruction (CMVO, no-reflow) development after PCI in ACS was carried out. 626 patients admitted in 2019-2020 were included, 418 (67%) - men, 208 (33%) - women.

Electrolytic exchange in organism under the conditions of vibration. Experimental studies.

The study deals with a wide spectrum of indices of the electrolytic metabolism--sodium, potassium, calcium, chlorides, magnesium, iron, copper, zinc, cobalt and manganese--in blood, organs and tissues under the conditions of experimental chronic exposure of whole-body vibration frequency of 50 and 150 Hz and velocity of 85 mm.s-1 during a three months experiment (3 h daily) Reference methods were used for the determination of the indices--atom absorption spectrophotometry (variants with flame and without flame), coulometric chlorine titrator, flame photometry, etc. The indices were examined three times (1, 2 and 3rd months).

Modelling coxsackie-virus infection in pregnant mice in long-term experiment.

The effect of virus infection on the organism of pregnant mice and their posterity was studied in experiment. The animals were infected with the prototype strain A13 (Flores) of Coxsackie virus which was administered on days 4, 7, 11, 15 and 19 of pregnancy. It has been demonstrated that pregnant mice are much more sensitive to the virus than non-pregnant females and that the placenta, along with the striped muscles, is the main reservoir of the virus.
