Nonconventional synchronization and energy localization in weakly coupled autogenerators.

The present work follows our previous study dealing with a new type of synchronization in a system of two weakly coupled generalized van der Pol-Duffing autogenerators. The essence of the effect revealed is that the synchronized oscillations are not stationary but accompanied by the most intensive energy exchange between the oscillators. The phase shift between the generators remains constant most of the time, except for vanishingly small transitional intervals.

[The differential diagnosis of the main forms of paroxysmal tachycardias and tachyarrhythmias].

A study is presented of 150 in-patients with paroxysmal tachycardias and tachyarrhythmias. Urgent management was carried out using a diagnostic algorithm designed by the authors that helped to establish early diagnosis using clinical adequate rational methods. Identification of clinico-pathogenetic form was realized in 95% of patients.

[Clinical effectiveness of cordarone in combination with other anti-arrhythmia agents in refractory atrial fibrillation and adverse effects of the drugs].

The study was undertaken to examine 105 patients with various circulatory diseases complicated by atrial fibrillation. Patients with refractory atrial fibrillation who had taken combined antiarrhythmic therapy were found to be more responsive to the combinations of cordarone + kinilentin (quinidine disulphate) and cordarone + ethacizin. The combinations of cordarone+digoxin and cordarone + finoptin were demonstrated to be less beneficial.

[Atypical attacks of stenocardia of effort occurring at rest].

Results of a clinico-instrumental examination and treatment of 320 patients with ischemic heart disease revealed that 147 of them showed both exertion stenocardia and angina pectoris attacks in seemingly physical rest that could be considered as spontaneous stenocardia. An analysis of the clinical picture of the disease in these patients allowed to distinguish five atypical variants of effort stenocardia that imitated stenocardia during rest: hemodynamic, stenocardia during arterial pressure elevation, cardiac arrhythmia, vasospastic and night effort stenocardia attacks. A differential approach to to complex treatment of patients with the above forms of effort stenocardia is necessary.

[Protracted course of acute pneumonias and their prophylaxis].

Different specific (immunological) and non-specific factors predisposing to protracted course of acute pneumonia were evaluated acute pneumonia and diagnostic errors. The course of pneumonia was protracted in 126 (48.9%) patients.

[Pathomorphosis and its significance in the diagnosis of tuberculosis and nonspecific diseases of the lungs].

The paper is a review of the literature data and original clinical experience on the contribution of pathomorphosis to current diagnosis of tuberculosis and nonspecific pulmonary diseases. the analysis of 1958 case histories elucidated relevant nosological composition of the lung lesions, frequency and causes of misdiagnosis. It is believed that pathomorphosis can noticeably facilitate differential diagnosis in lung diseases even at early outpatient stage.

[The side effects of antibiotics in chronic bronchitis].

The author investigated the frequency and character of side-effects to penicillin, levomycetin, tetracycline in the treatment of 92 patients with different forms of chronic bronchitis. Clinically all side-effects were subdivided in dysbacteriosis, allergic, toxic and mixed. It was established that the high incidence of side-effects furthers allergization of the body and potentiation of bronchial spasm.

[Use of decamethoxine in the complex treatment of chronic bronchitis].

Seventy-two patients with chronic bronchitis were examined and divided into 3 groups. Group I consisted of patients with chronic catarrhal bronchitis (CCB) group II of those with chronic purulent bronchitis (CPB), group III of subjects with bronchitis associated with purulent destructive pulmonary diseases. All the patients received combined treatment with decamethoxin as an antibacterial modality.

[Dynamics of the antiprotease system and ventilation indicators during treatment of chronic bronchitis].

The relationship between the antitryptic activity of the blood serum, bronchoalveolar secretion and ventilatory indices of the external respiration function in 85 patients with chronic bronchitis in the process of treatment is described. The above findings allow to recommend antibiotics for wide use only in exacerbations of purulent bronchitis while in other clinical variants reduction of drug loads result in increased therapeutic efficiency.
