The study was undertaken to examine 89 patients with acute myocardial infarction whose pulmonary pressures were measured under monitoring. The findings were compared with the time course of necrotic focal formation. The rate of the latter was found to determine central hemodynamic changes. High necrotization rates were ascertained to be directly related to(More)
A model for the limiting surface tension of surfactant solutions (surface tension at and above the critical micelle concentration, cmc) was developed. This model takes advantage of the equilibrium between the surfactant molecules on the liquid/vacuum surface and in micelles in the bulk at the cmc. An approximate analytical equation for the surface tension(More)
The effect of an endotoxin from Sh. Boydii on the biotransformation of amidopyrine and acetanilide, the activity of microsomal monooxygenases, hemoxygenase, and xanthine oxidase, the lipid peroxidation (LPO) intensity, the phospholipid spectrum, and the solubilization of microsomal membrane components was studied by intraperitoneal injections (2.5 mg/kg) in(More)
A change in filterability of erythrocytes through a cellulose filter with pores 7 microns in diameter was examined in 67 patients with acute myocardial infarction. Dynamic evaluation of the filterability was compared with a process of necrotic focus development in time. The filterability was ascertained to have various phases coinciding with the development(More)
The relationship between necrotic focus characteristics (weight and rate of necrotization) and the clinical pattern of myocardial infarction was examined. Necrosis weight was shown to have no significant effect on the course of myocardial infarction, while maximum necrotization rate was found to be a valuable predictive factor: the higher the necrotization(More)
A mathematical procedure is proposed for quantitative assessment of necrosis weight, which is based on the processing of serial measurements of peripheral MB CPK activity in patients who died of acute myocardial infarction. The method is based on statistical treatment of biochemical findings and the results of postmortem determination of necrosis weight. A(More)
We consider a spin-[Formula: see text] kagome-like chain with competing ferro- and antiferromagnetic anisotropic exchange interactions. The ground state phase diagram of this model consists of the ferromagnetic and ferrimagnetic phases. We study the ground state and the low-temperature properties on the phase boundary between these phases. The ground state(More)
