[The impact of thromboprophylaxis with enoxaparin on bleeding rate in rejuvenating facelift procedures].

A retrospective study on safety of prophylactic use of Enoxaparin in rejuvenating face lift procedures. The prophylactic use of Enoxaparin was not found to be associated with increased perioperative bleeding or higher incidence of postoperative hematomas requiring reoperation.

[Systemic components of pathogenesis of lower-limb atherosclerotic gangrene].

A prospective controlled study was carried out in a total of thirty-four patients presenting with atherosclerotic gangrene ofthe lower extremities. Surgery was preceded by studying haemostasiograms, biochemical parameters and indices of the functional system of detoxication, level of acute-phase proteins, cytokines, stress enzymes. It was determined that irreversibility of tissue damage in atherosclerotic gangrene of the lower limbs results in the development of the main pathogenetic phenomena of systemic impairments, i.

[Activation of intravascular microcoagulation of blood in patients with atherosclerotic gangrene of the lower limbs].

A prospective study was carried out in order to investigate the system of haemostasis in a total of sixty patients presenting with atherosclerotic gangrene of a lower extremity who were then subjected to high amputation. The operative intervention was preceded and followed by determining the following parameters: antithrombin III (AT-III), fibrinogen (FG), thrombin time (TT), activated partial thromboplastin time (APTT), prothrombin time (PT), the number of the soluble fibrin-monomeric complexes (SFMC) and D-dimers, euglobulin fraction clot lysis time, the amount and aggregation activity of blood platelets. The findings obtained while studying haemostasis in patients with irreversible ischaemia of the lower limbs demonstrated activation of the intravascular microcoagulation of blood prior to the operation.

[Early postoperative systemic inflammatory response in patients with lower extremity atherosclerotic gangrene].

A prospective controlled study was conducted in 30 patients with lower extremity atherosclerotic gangrene. Their mean age was 66.1 +/- 9.

[Lipid peroxidation before and after amputation of the lower extremity in patients with atherosclerotic gangrene].

Activity of lipid peroxidation processes in blood was studied in 60 patients with atherosclerotic gangrene of the lower extremity subjected to amputation of the extremity in a prospective controlled investigation. Activation of the lipid peroxidation processes with a lower number and less activity of the antioxidant system enzymes was demonstrated in patients with severe critical ischemia of lower extremities. The operation trauma was followed by further stress of the system of free radical oxidation of lipids.

[Postoperative analgesia in high amputation of the lower extremity].

A prospective controlled study was conducted in 48 patients with atherosclerotic gangrene in the postoperative period after above knee amputation. It showed the tension of the cardiovascular and sympathoadrenal systems in patients with atherosclerotic gangrene in the pre- and early postoperative periods. Continuous epidural infusion of a local anesthetic ensures effective pain relief throughout the early postoperative period.

On inherited fertility in biological systems: a model of correlated fluctuations in the stochastic branching process.

A new evolutionary model with hereditary modes considered as correlated fluctuations of fertility has been proposed. It has been demonstrated that the model allows the global statistical properties of the system to be evaluated, e.g.

Handedness, origin of life and evolution.

Biological polymers have a preferred chirality ond can replicate themselves. Physical arguments provide insight into which of these unique and apparently related properties evolved first, and by what mechanism.

Chiral purity of nucleotides as a necessary condition of complementarity.

This work discusses the question about the role of chiral purity (homochirality) of nucleotides in the formation of complementary replicas. A qualitative answer to this question can be obtained from molecular models constructed to simulate the chiral defect in the polynucleotidic chain. It shows the necessity of homochirality of nucleotides for the complementarity preservation.
