[Detection of markers of hepatitis B and D virus infection in biological media and dried blood spots.]

The aim of this study was to assess the rates of detection of the major markers of infection with hepatitis B and Delta (D) viruses in serum, saliva and dry blood dots (DBS) as a possible option for serological studies among the population of the endemic region in conditions of limited laboratory resources. For this purpose, paired samples of blood serum and DBS, blood serum and saliva from patients with chronic hepatitis B with Delta agent living in the Republic of Tyva, which is endemic for this disease. HBsAg was detected in 289 (100%) serum samples, in 88/92 (95.7%) saliva samples, in 60/80 (75%) DBS samples, stored three years at room temperature, and in 111/117 (94.9%) DBS stored one year at the same conditions. Anti-HBcore was detected in 209 (100%) serum samples, while in saliva and DBS samples this marker was detected in only 13.04% (12/92) and 19.7% (23/117), respectively. Anti-HDV antibodies in serum were detected in 209 (100%) samples collected from patients in 2017-2018. In saliva and DBS anti-HDV were not detected in any sample. This difference in the detection rates of anti-HBcore and anti-HDV might be accounted for the fact that the HBV core protein is a very strong immunogen, indusing the production of anti-HBcore in high concentrations. Probably, the concentration of anti-HDV is much lower, which explains its absence in saliva and DBS in patients with hepatitis B+D. Samples of biological media (saliva), as well as DBS can serve as an alternative material for the detection of HBsAg in screening and research prevalence studies. Meanwhile, the definition of anti-HDV in such media is not possible due to the false negative results. Due to the high probability of superinfection with HDV in patients with HBV in endemic areas, the detection of HBsAg in alternative media (saliva or DBS) should be followed by testing for anti-HDV in serum samples.

[The detection of antibodies to endogenous bioregulators for evaluating functional condition of health of portsmen.]

The evaluation of functional condition of health of sportsmen doing Greek Roman wrestling was implemented using detection of level of antibodies to serotonin, histamine, dopamine, glutamate, GABA, orphanine, endorphin, angiotensin. The study established a reliable increasing of level of antibodies to orphanine, ß-endorphin, GABA and glutamate under increasing of duration of physical load. The content of antibodies to other regulators of adaptation had no statistical difference. The developed technique can be applied in evaluation of objectification of functional condition of sportsman with purpose of selecting optimal training process.

[Features of morbidity community-acquired pneumonia among young recruits].

Were examined 3338 military personnel of the combined training center. 183 of them diagnosed community-acquired pneumonia, in 3155 focal and infiltrative changes in lung tissue were not identified. The analisys of prevalence been made among young recruits of the acute respiratory illness before arriving in part and at the assembly point, foci of chronic infection, smoking, low body weight. 511 military personnel arrived at the training center in the disease state with symptoms of acute respiratory illness. Examined the relationship these risk factor to the development of community-acquired pneumonia in this category of servicemen.

[Antihypertensive therapy in the elderly patients with metabolic syndrome].

The article is concerned with modern methods of assessment of arterial hypertension in patients with metabolic syndrome and characteristics of modern antihypertensive drugs and its combinations necessary for the elderly. The authors gave their own example of treatment of more than 2000 patients with arterial hypertension and metabolic syndrome.

[Principles of antihypertensive therapy in metabolic syndrome].

Clinical features of arterial hypertension in patients with metabolic syndrome are described with reference to antihypertensive therapy and the choice of adequate drugs for the purpose. Characteristics of the most frequently used preparations are presented along with algorithms for their application depending on clinical condition. Advantages of combined antihypertensive therapy in metabolic syndrome are substantiated, their most efficacious combinations are recommended.

[Correction of the influence of clinostatic hypokinesis on encephalitic circulatory dynamics during the sleep in patients with hypertensive disease].

During the sleep person is in the state of antiorthostasis, this state provokes vascular cerebral abnormalities (night cerebral hypervolemia). The nature of encephalon blood supply is changing in this horizontal state, in the result there is lowering of hydrostatic blood pressure, rise of the encephalon blood supply and more difficult venous outflow. 60 patients with essential hypertension (1-2 phases) at the age of 64.2 +/- 1.8 years which were in the state of slightly raised upper segment of the head and body during night sleep were examined. By the method of the cerebral venous hemocirculation defined. Conclusion. Cerebral arterial blood flow of examined patients has increased by 25-30% during the sleep, the changes of arterial and cerebral venous hemocirculation have attended hypervolemia. Being in the state of upper (by 10-15 degrees) head of the bed decreases blood redistribution and decreases the extension of cerebral blood circulation's acute abnormalities.

[Daily blood pressure profiles and endothelial functions during long-term treatment of arterial hypertension with angiotensin-converting enzyme inhibitors]. / Sutochnye profili arterial'nogo davleniia i funktsii éndoteliia pri dlitel'nom lechenii arterial'noi gipertonii ingibitorami antiotenzinprevrashchaiushchego fermenta.

Clinical practice has been recently applied new approaches to classifying patients with arterial hypertension (AH), which are based on the determination of the summary risk suggesting the prognosis of the disease. This approach is quite efficient due to the fact that it takes into account a combination of the comparable clinical symptoms of AH, which characterize its course. The paper presents data on the values of blood pressure (BP) in AH and on daily BP profiles (DBPP) in 494 patients with different categories of a risk and on their endothelial function. It also gives the results of achievement of target BP levels in patients with AH having different categories of a risk during long-term (36-month) treatment with enapril and perindopril, as well as data on its impact on endothelial vasomotor function. The findings suggest that the higher the risk is, the more severe the hypertensive syndrome is; that the redistribution of DBPP occurs towards prognostically poor types and endothelial dysfunction (EDF) progresses. Treatment with angiotensin-converting enzyme (ACE) inhibitors results not only to the achievement of target BP levels and to the normalization of DBPP, but also to the amelioration of EDF. Moreover, the co-administration of ACE inhibitors and isosorbide-5-mononitrates causes additional antiischemic effects.

[Comparison of the tocolytic and hemodynamic effects of calcium channel blockers in pregnant rats]. / Sravnenie tokoliticheskogo i gemodinamicheskikh éffektov blokatorov kal'tsievykh kanalov u beremennykh krys.

It was demonstrated in experiments on pregnant rats that toxolytic doses of the calcium channel blockers nifedipine, cardiazem (diltiazem) and verapamyl reduce blood pressure, heart rate, and doppler ultrasound velocity in the uterine artery. Toxolytic doses of sensit (fendilin) do not change hemodynamics in pregnant rats.

[The use of saliva for study in the immunoenzyme analysis of postvaccinal and postinfectious immunity to influenza]. / Ispol'zovanie sliuny dlia izucheniia v immunofermentnom analize postvaktsinal'nogo i postinfektsionnogo immuniteta k grippu.

Paired specimens of blood sera, upper respiratory tract secretions, and saliva from healthy, influenza-infected, and live influenza trivaccine-immunized humans were tested in parallel by HI tests and enzyme immunoassay (EIA). The resulting comparative data suggest that determination by EIA of specific secretory IgA in the saliva may be recommended as an independent test for large-scale influenza diagnosis, evaluation of the immune status of people, and trials of influenza vaccines. By immunologic parameters, this method is not inferior to the standard ones. At the same time its advantages include simplicity and readily available large volumes of saliva even from children as well as no necessity to bleed subjects to be examined.

A method for facial nerve mobilization is suggested, developed on cranial preparations of adult subjects. The authors have distinguished characteristic topographic and anatomic regularities that are essential in surgery of the mastoid process and parotid-masticatory area for tumor or nontumorous involvement of the parotid gland in case of the facial nerve involvement in the process.

[Intensive therapy of DIC-syndrome in patients with acute renal insufficiency caused by long-term crush syndrome]. / Intensivnaia terapiia DVS-sindroma u bol'nykh s ostroi pochechnoi nedostatoch-nost'iu, obuslovlennoi sindromom dlitel'nogo sdavleniia.

Impairment of parenchymatous organs, primarily kidneys, responsible for their dysfunction in crush syndrome results in many respects from disseminated intravascular coagulation (DIC). It is also associated with hemorrhagic complications. It is demonstrated that treatment modalities aimed at arrest of DIC syndrome (plasmapheresis, heparin, dysaggregation drugs, transfusions of large amounts of fresh frozen plasma) stopped bleeding and septic shock in 12 patients with crush syndrome following the earthquake in Armenia (1988).

[Effects of mildronate (quaterin) on hemodynamics in spontaneous and artificial heart rhythm in patients with ischemic heart disease]. / Vliianie mildronata (kvaterina) na gemodinamiku pri spontannom i isskustvennom serdechnom ritme u bol'nykh ishemicheskoi bolezn'iu serdtsa.

Central hemodynamic parameters under the effect of mildronate were examined in 62 patients suffering from coronary heart disease, 35 of these with acute myocardial infarction complicated by acute left-ventricular insufficiency and 20 with atherosclerotic cardiosclerosis with chronic cardiac insufficiency. The drug effect was assessed in two groups of patients after a single intravenous injection of 0.5-3 g. In group 1 (n = 53) mildronate effect on central hemodynamic parameters was assessed in spontaneous cardiac rhythm. Variously directed statistically unreliable hemodynamic shifts were revealed, related to heart rhythm changes. In group 2 (n = 9) the drug effect on heart rhythm was eliminated with the use of two-chamber electrocardiostimulation, and various hemodynamic regimens with hypo-, eu-, and hyperkinetic circulation types were artificially created by changing the A-V interval. Mildronate had no effect on the hemodynamics during two-chamber electrocardiostimulation.
