[Fauna of Rare and Poorly Studied Ectoparasites of bats in Southern Siberia].

Forty-six chiropteran specimens from seven species have been captured on the territory of Southern Siberia. From them, 676 ectoparasites of 16 species (gamasid mites and insects) were collected. The bat fly Basilia mongolensis mongolensis Theodor, 1966 was found in Russia for the first time. The gamasid mites Spinturnix maedai Uchikawa et Wada, 1979 and Macronyssus hosonoi Uchikawa, 1979 have not previously been registered in Siberia. Several species have been recorded on new hosts. Three species of gamasid mites out of the genus Macronyssus are, probably, new to science. New data on the ecology of low-abundant and understudied bat species belonging to the Siberian-Far Eastern complex have been provided.

[Cerebral oximetry in the perioperative evaluation of the reserve of cerebral circulation in patients with brachiocephalic artery lesions]. / Tserebral'naia oksimetriia v otsenke rezervov krovoobrashcheniia golovnogo mozga v perioperatsionnom periode u bol'nykh s porazheniem brakhiotsefal'nykh arterii.

The reactivity of cerebral vessels and the reserve of collateral compensation of cerebral flow were studied in 71 patients with perioperative carotid stenosis of different degrees. Cerebral oximetry was made at rest and during hypercapnic and compression loads. The method's efficiency was demonstrated for the preoperative evaluation of the cerebrovascular reserve in patients with atherosclerotic affection of vessels in the brachiocephalic stem. A comparison of the preoperative and intraoperative dynamics of rSO2 at compression points at the feasibility of using the cerebral oximetry in predicting the degree of reduced regional oxygenation of the brain in the basin of an intraoperatively pinched artery.

[Calcium 2+ Response of Lymphocytes to Standard Test-Substances in Patients With Ischemic Heart Disease and Heart Failure] / Kal'tsievyi otvet limfotsitov na standartnye test-veshchestva u bol'nykh ishemicheskoi bolezn'iu serdtsa s nedostatochnost'iu krovoobrashcheniia.

Changes of [Ca 2+]i were studied in peripheral blood lymphocytes of patients with ischemic heart disease and heart failure. Basal [Ca 2+]i and its changes under action of mitogenes (PHA, Con A; 10 mcg/ml), butylhydroxyquinone (BHQ; 9-14 mcM) and arachidonic acid (3-10 mc/M) were measured. Patients with heart failure had pronounced changes of kinetics and amplitude of Ca 2+ response of lymphocytes to mitogenes, significantly higher amplitudes of responses to BHQ (in patients with stage IIB and III heart failure), as well as additional increment of [Ca 2+]i in response to rachidonic acid during action of optimal concentrations of BHQ. This data allowed to propose presence of supplementary inositol triphosphate insensitive calcium depots in cells of patients with heart failure. Furthermore it was possible to assume lowering of sensitivity of Ca 2+ ATP-ase of plasmatic membranes to its natural regulators.

[On possible prognostic values of anti-endotoxin immunological parameters in acute myocardial infarction]. / O vozmozhnom prognosticheskom znachenii pokazatelei anti-éndotoksinovogo immuniteta pri ostrom infarkte miokarda.

Endotoxin is a biologically active substance that has a lipopolysaccharide structure. It is found in the cell walls of microorganisms, principally gram-negative bacteria. By contacting with the cell, endotoxin enhances immunity. The findings suggest that acute myocardial infarction (AMI) occurs due to low immunity that remains the same at week 3 of the disease, thus the levels of antiendotoxin agents may be used in predicting AMI.

[Effect of a "running" pulse magnetic field on certain humoral indicators and physical ability to work in patients with neurocirculatory hypo- and hypertension]. / Vliianie "begushchego" impul'snogo magnitnogo polia na nekotorye gumoral'nye pokazateli i fizicheskuiu rabotosposobnost' u bol'nykh s neirotsirkuliatornoi gip- i gipertenziei.

The influence of "running" impulse magnetic field in patients with neurocirculatory hypo- and hypertension was studied. It has been determined that magnetotherapy in all patients increased physical load tolerability and at the same time produced different effects on hemodynamics (lowering blood pressure in hypertension and increasing it in hypotension). In patients with neurocirculatory hypotension the slightly expressed positive clinical effect was obtained, that makes "running" impulse magnetic field therapy useless in this pathology. At the same time in patients with neurocirculatory hypertension "running" impulse magnetic field therapy resulted in significant improvement of physical tolerability, improvement of patients general condition, blood pressure decrease, lowering of pressor power generation concentration, correcting effect on aldosterone blood content. These data witness for the usefulness of this method in treatment of patients with neurocirculatory hypertension.

["Running" pulse magnetic field in treating stenocardia]. / "Begushchee" impul'snoe magnitnoe pole v lechenii stenokardii.

The influence of "running" impulse magnetic field, antianginal drugs and their combination on physical load tolerability, hemodynamics and functional state of hormonal system in patients with stable angina pectoris was studied. "Running" impulse magnetic field therapy produced marked antianginal effect in patients with I-II class angina and it was effective in combination with antianginal drugs in patients of III class angina. The reduction of attack frequency and significant physical load tolerability improvement was determined. The correcting influence of "running" impulse magnetic field on hypophysis-thyroid system hormones (TTH, T3, T4) was revealed, that correlates with physical load tolerability and myocardial contractility improvement. As monotherapy, the "running" impulse magnetic field can be administered to the patients with stable angina of I-II class and in combination with antianginal drugs- to the patients with severe angina.

[The factors in local protection of the lungs and the status of cellular immunity in patients before and after thoracic operations]. / Faktory mestnoi zashchity legkikh i sostoianie kletochnogo immuniteta u bol'nykh do i posle torakal'nykh operatsii.

Twenty-seven patients operated on the lungs and heart (aortocoronary bypass surgery) were examined. Cellular immunity parameters were studied in venous blood, and the function of immunocompetent cells, status of the surfactant system, and albumin level were assessed in the bronchoalveolar washings off. An impairment of the T-component of cellular immunity (T-suppressors), reduced level of alveolar macrophages and of their phagocytic activity, reduced activity of the surfactant system, and increased albumin content in the bronchoalveolar lavage fluid were revealed in patients with a complicated course of the postoperative period. In patients with a smooth course of the postoperative period these shifts were less expressed. The data indicate the necessity of antibacterial and immunomodulated therapy in such patients before and after surgery.

[The pathogenesis of hypoventilation in the operated lung]. / K voprosu o patogeneze gipoventiliatsii operirovannogo legkogo.

The content of immunocompetent cells, activity of lipid peroxidation processes, function of the surfactant system, and levels of prostacyclin and thromboxane were studied in 9 patients with resected lungs in the perioperative period separately for the intact and operated on lung. The function of immunocompetent cells deteriorated in both lungs after surgery. The levels of albumin and thromboxane were increased in the bronchoalveolar washings from the lung operated on reliably more than in those from intact lung, and the surface active characteristics deteriorated. Eight patients developed hypoventilation of the operated on lung in the postoperative period.

[Evaluation of pulmonary hypertension by dopplerography in patients with nonspecific pulmonary diseases]. / Otsenka gipertenzii malogo kruga krovoobrashcheniia u bol'nykh nespetsificheskimi zabolevaniiami legkikh metodom dopplerografii.

Doppler echocardiography was used to quantify pulmonary hypertension and phase pattern of right heart systole in 140 patients with nonspecific pulmonary diseases to study hemodynamic characteristics of pulmonary circulation and right heart as well as external respiration. There appeared a relationship between the severity of pulmonary hypertension, bronchial obstruction and arterial hypoxemia. It seems that in nonspecific pulmonary diseases hemodynamic changes arise prior to functional disorders of external respiration.

[Characteristics of external respiration function and pulmonary circulation in patients with ischemic heart disease complicated by disorders of intraventricular conduction]. / Osobennosti funktsii vnechnego dykhaniia i legochnogo krovotoka u bol'nykh ishemicheskoi bolezn'iu serdtsa, oslozhnennoi narusheniiami vnutrizheludochkovoi provodimosti.

The authors provide evidence on the condition of external respiration and hemodynamic shifts in the lesser and greater circulation in coronary patients with bundle-branch block; establish early objective quantitative criteria of the diagnosis of hemodynamic impairment arising in formation of the above blocks basing on ECG, phonocardiography, echocardiography findings; compare hemodynamic effects of single-dose nitrosorbide and corinfar in the above patients. Nitrosorbide and corinfar correct hemodynamics and external respiration, the former being more effective in normalizing the greater, while corinfar the lesser circulation.

[Cardiorespiratory disturbances in atrioventricular block]. / Osobennosti kardiorespiratornykh narushenii pri atrioventrikuliarnykh blokadakh]

The paper covers questions of the emergence and progressing of cardiorespiratory disturbances in coronary patients with defective atrioventricular conduction. The authors characterize central and peripheral hemodynamics in the above patients, diastolic ventricular filling, external respiration, the disturbances of which were studied in correlation with hemodynamic features and lipid peroxidation. The patients were examined for effects on their cardiorespiratory system of cardioselective beta-blockers, adrenomimetics, antioxidants, membrane stabilizers.

[The effect of quinidine monotherapy and combined therapy with digoxin on the central hemodynamics in patients with heart rhythm disorders]. / Vliianie monoterapii khinidinom i sochetannoi terapii s digoksinom na tsentral'nuiu gemodinamiku u bol'nykh s narusheniiami ritma serdtsa.

The study was undertaken to examine 84 patients mainly with coronary heart disease and various cardiac arrhythmias. Quinidine monotherapy was found to normalize heart rate depending on its baseline values: it reduced heart rate in tachycardias and increased it in bradycardia. In patients with severe myocardial damage, especially in hypertension, quinidine decreased cardiac index, whereas total peripheral resistance increased. With quinidine, systolic pressure, stroke and cardiac indices showed a more decrease, whereas diastolic pressure and total peripheral resistance displayed a more increase in the standing position. Supplement of digoxin corrected negative quinidine-induced hemodynamic changes and orthostatic failures.

[Evaluation of antianginal effects of running pulse magnetic field and drug therapy on the physical working capacity and hemodynamics in patients with stable angina pectoris]. / Otsenka antianginal'nogo vliianiia begushchego impul'snogo magnitnogo polia i farmakoterapii na fizicheskuiu rabotosposobnost' i gemodinamiku u bol'nykh so stabil'noi stenokardiei.

The effects of the running pulse magnetic field, antianginal drug therapy and their combinations on the physical capacity were compared in 60 patients with Functional Classes I-III stable angina pectoris. Monotherapy with the running pulse magnetic field was found to produce an antianginal effect in patients with Functional Classes I-II angina pectoris, but the efficacy of drug therapy increased when antianginal drugs were used in combination with running pulse magnetic field in patients with severe angina.
