[Sleep and fine motor skills: the influence of sex and level of physical activity].

Objective: To examine the influence of sleep quality on psychophysiological testing results and autonomic state in university students of both sexes with different habitual physical activity level.

Material And Methods: One hundred and twenty-four 6 year medical students (88 women and 36 men) and 80 sport science students (42 women and 38 men) underwent a comprehensive psychophysiological study, including 7 tests: simple motor reaction, choice reaction, reaction under conditions of interference, reaction to a moving object, critical fusion frequency, as well as static and dynamic (by profile) dexterity tests. Autonomic status was assessed using heart rate variability, sleep quality and alertness were assessed based on self-report, and in athletes, using the Pittsburgh Sleep Quality Questionnaire (PSQI).

[A case of rare inhibitory coagulopathy - acquired hemophilia A].

Inhibitory coagulopathy is a rare variant of hemorrhagic syndrome. Acquired hemophilia A is caused by the formation of inhibitors (antibodies) to Factor VIII of the blood coagulation system leading to impaired activation of the key stage of blood clotting (factor X) and development of hemorrhagic syndrome of different severity. Acquired hemophilia A is a rare disease with an incidence of 1.

[Specific features of pollination in the Manchurian birthwort Aristolochia manshuriensis].

An analysis of pollination system in Aristolochia manshuriensis has shown that flower structure in this species is strictly adapted to cross-pollination, but the possibility of an autogamous or geitonogamous type of self-pollination with the involvement of insects is not excluded. The flowers of A. manshuriensis are most frequently visited by flies of the family Anthomyiidae, which markedly contribute to their pollination.

[Novel possibilities of antithrombotic therapy in patients with chronic heart failure].

Modern approaches to prevention of venous thromboembolic complications in patients with chronic heart failure are analyzed in this review which contains results of large studies of low molecular weight heparins. In MEDENOX trial the use of enoxaparin in medical patients was associated with 63% reduction of risk of thrombosis. The authors own experience showed that 2 weeks of therapy with enoxaparin in patients with chronic stage IIB-III heart failure caused significant lowering of soluble fibrin-monomer complexes, fibrinogen, and index of turbo-dynamic potential.

[Features of neurotransmitter pool in cerebrospinal fluid of patients with epilepsy].

The paper deals with the state of neurotransmitter pool in cerebrospinal fluid of epileptic patients. There were significant peculiarities of the dynamics of both excitatory (glutamate, aspartate) and inhibitory (GABA, glycine, taurine) neurotransmitters in respect of the severity of the pathologic process, frequency and type of convulsive seizures. The correlation found between a degree of the disease severity and a level of glutamate in cerebrospinal fluid after the seizures and between them could be a criterion for the prognosis of epilepsy.

Pyocinovar and serovar characteristics of 91 P.aeruginosa strains isolated from patients and the environment in a hospital for premature children, a child survey hospital and a neonatological hospital. The leading epidemiological markers of P.

[Microbiology of suppurative wound in laser radiation].

Comparative quantitative and qualitative appraisal of purulent lesions of the soft tissues in surgical patients treated with the infrared lasers "Uzor" (pulse) and "Skalyar (continuous) and by the traditional methods (antibiotics, antiseptics, ointments) was conducted under clinical conditions. Abscesses, mastitis, and phlegmons were studied before and after the operation and on the 3rd, 6th, and 12th postoperative day. It was found that Staphylococcus aureus in a monoculture was the etiological cause of purulent infection in 75.

[Effect of fragmin, a low-molecular heparin, on hemostasis in patients with alimentary-constitutional obesity].

The authors conducted comparative study of the hemostasis indices before and in the immediate period after operation for formation of a small stomach in 31 patients with stage III-IV alimentary-constitutional obesity, in 50 patients without obesity who underwent operation on the stomach, and in 15 volunteers. Nonspecific prevention of thrombogenesis was performed in all patients with normal weight and those with obesity. Patients with obesity were given in addition specific thrombogenesis prevention with nonfractionated heparin (group I) and fractionated low-molecular heparin-fragmin produced by KABI (groups II and III).

[The Kearns-Sayre syndrome].

The paper describes Kearns-Sayre's syndrome, a rare hereditary neuromuscular disease, in a patient aged 17 years. The clinical picture of the disease had a classical triad: external ophthalmoplegia, pigmentary retinopathy, and cardiac conduction disturbances. This triad was supplemented with other polymorphous symptoms characteristic of the syndrome, such as moderate myopathic syndrome, hemeralopia, physical infantilism, hypogonadism, pyramidal syndrome.

[The indices of the hemostatic system in atopic dermatitis patients during treatment by hyperbaric oxygenation].

Studies of the blood coagulation processes in the patients with atopic dermatitis have revealed an increase in the activities of the blood coagulation system in the acute phase of the disease, the degree of these changes depending on the severity and activity of the pathologic process. Hyperbaric oxygenation, an effective treatment modality for atopic dermatitis, normalized some of the altered parameters of the hemostasis system.
