[Genetic analysis of the contributions of individual chromosomes to the expression of mating behavior traits in Drosophila melanogaster].

The model of isogenous strains with chromosome substitutions has been used to estimate the relative contributions of the X chromosome and autosomes (chromosomes 2 and 3) to the control of some mating behavior traits in Drosophila melanogaster. It has been found that the male sexual activity (SA), female sexual receptivity (SR), and copulation latency (CL) are determined by interaction between X-chromosome and autosomal genes, whereas the copulation duration (CD) is mainly controlled by the X-chromosome genes. The synthesized isogenous strains have been shown to be more similar to hybrids than to the original strains.

[Motor and secretion function of stomach and duodenum, duodenogastric reflux in patients with duodenal ulcer].

Gastric secretion, motor function and tonicity of the stomach and duodenum, duodenogastric reflux were studied in inpatients with two clinicopathogenetic types of duodenal ulcer: observed at young age (type 1) and in later life (type 2). The examination included pH-metry with simultaneous balloon cimography, chromogastroduodenoscopy with Kongo-red, tests for Helicobacter pylori conducted on the biopsy samples. All the patients were found to have continuous acid production.

[Duodenogastric reflux in patients with alimentary obesity].

The authors analyze findings from a comprehensive clinical and instrumental evaluation of 59 patients presenting with duodenogastric reflux. The above findings suggest that underlying the duodenogastric reflux in those patients having surplus body mass might be hypotonia of the stomach, particularly its pyloric portion. In patients with body mass that do not deviate from physiologic norms regurgitation of bile into the stomach results from the presence of duodenal dyskinesia by hypertonic type.

[The role of different investigations in diagnosis of functional disorders of the biliary system].

The paper presents the results obtained upon examination of inpatients with various types of biliary dyskinesia. The examination included: fraction chromatic duodenal intubation, stepwise manometry, cholecystography, ultrasound investigation of the liver, gall bladder, biochemical tests of the bile. Fraction duodenal intubation discovered gall bladder dysfunction.

[The use of nitrates and slow calcium channel blockers in the treatment of patients with ischemic heart disease and disorders of intraventricular conduction].

Data are submitted on the condition of haemodynamics of greater and lesser circulation in patients with ischemic heart disease (IHD) presenting with the bundle-branch block. On the basis of the results from a combined clinical-instrumental investigation involving electro- and echocardiography the authors present the early objective quantitative criteria for the diagnosis of those haemodynamic shifts occurring in formation of the bundle-branch block. The blockade of the left bundle of His has a more pronounced effect on the greater circulation haemodynamics while that of the right one--on the lesser circulation.

[Dynamics of biliary prostaglandin secretion in patients with dyskinesia of the biliary tracts].

The time course of biliary secretion of prostaglandins (PG)E1 and F2 alpha was studied in 20 patients with primary dysfunctions in the cholepoietic system. The studies indicated that baseline high PGE1 levels and slow increases in PGF2 alpha during vesical reflex might be one of the factors predisposing to biliary hypokinesia. In patients with Oddi's sphincter spasms, the period of active PGE1 synthesis coincides with that of sphincter spasm.

[Evaluation of pulmonary hypertension by dopplerography in patients with nonspecific pulmonary diseases].

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.

[The possibilities of using intermittent normobaric hypoxia for treating hypertension patients].

The response to intermittent normobaric hypoxia (INH) created in breathing gas hypoxia mixture (10% oxygen, 90% nitrogen) was evaluated in 123 patients with essential hypertension stage I and II. Hypoxia adaptation effects on central hemodynamics, physical performance, kinetics of oxygen exchange were studied. A pronounced response to INH persistent for 6 months was demonstrated in 80.

[Characteristics of external respiration function and pulmonary circulation in patients with ischemic heart disease complicated by disorders of intraventricular conduction].

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.

[The evaluation of the efficacy of adaptation to intermittent normobaric hypoxia as a method for treating hypertension].

Clinical and functional condition was examined for 75 patients with essential hypertension stage I and II who had developed adaptation to normobaric cyclic-fractionated hypoxia. The latter was produced by gas hypoxic mixture (10% oxygen, 90% nitrogen) in its inhalation. A pronounced positive effect of such treatment modality was registered in 86.

[Adaptational reactions in patients with acute pneumonia].

Adaptive reactions were studied in 80 patients with acute pneumonia. In the hospital 94.1% patients showed reactions of stress and incomplete reactions of training and activation.

[A comparative evaluation of the hemodynamic effects of nitrosorbide, korinfar, obzidan and spesikor in blockade of the left branch of the bundle of His].

The paper deals with hemodynamic parameters in the greater and lesser circulations in patients with CHD concurrent with left bundle branch block. Based on the results of clinical and instrumental studies involving electrocardiography, phonocardiography and echocardiographic techniques, the authors provide early objective measures for diagnosing the hemodynamic changes occurred with development of left bundle branch block. The authors make a comparative assessment of hemodynamic effects produced by single administration of nitrosorbide, corinfar, obsidan, and spesicor in the patients examined.

[The correction of motor-tonic disorders of the gastrointestinal tract and of duodenogastric reflux with laser radiation].

Forty-five patients with duodenogastric reflux and defective gastroduodenal motor tonicity (gastroduodenal hypotonia, duodenal hypertension, gastric hypotonia in combination with duodenal hypertension) were exposed to He--Ne laser radiation. The impact was focused on the biologically active points G14, TR5, VC15, E21. The treatment resulted in normalization of the gastrointestinal pressure gradient, in discontinuance or reduction of duodenogastric reflux.

[The "jumping Frenchman from the state of Maine" syndrome].

The paper describes a clinical history of a rare neurological syndrome in an old man who had daily episodes of involuntary jumping for 25 years. The man started jumping in response to sudden loud sounds and other stimuli. The diagnosis and origin of this unusual syndrome are discussed.

[Cardiorespiratory disturbances in atrioventricular block].

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 function of the left heart in blockade of the left bundle of His].

A complex Doppler echocardiographic study was performed in 134 patients with complete block of the left bundle branch, its anterior branch or with concurrence of these two types of intraventricular conduction disturbance. The authors identified 5 types of paradoxical ventricular septal motion, which were related to the specific features of intraventricular asynchronism and ventricular electric systole. Type I shows the greatest decrease in left ventricular contractility, left atrial overload and phasic destruction of left ventricular systole, which reflects the processes of depolarization and repolarization propagation in the myocardium.

[The correction of functional disorders of the bile-secreting system by using laser radiation].

He-Ne laser irradiation of biologically active points and infrared laser irradiation of the liver were employed to improve gallbladder and sphincter functions, bile production and biochemistry, respectively, in a total of 57 patients with biliary dyskinesia presenting as hypokinetic dyskinesia of the gallbladder, hyperkinetic dyskinesia of the sphincter of Oddi or the combination of the two affections. Simultaneous use of the two kinds of laser irradiation appreciably shortens treatment duration, abolishes biliferous dysfunction, reestablishes physiological balance of bile components in case of its initial lithogenic potential.

[Doppler echocardiographic assessment of left atrial and left ventricular function during right bundle branch block].

Electrocardiographic, echocardiographic and Doppler echocardiographic studies were performed in 44 patients with coronary heart disease and complete right bundle branch block. The patients were found to have an impaired phase pattern of left ventricular systole and diastole as more prolonged length of its isometric relaxation and contraction, lower economic feasibility and efficiency of its contraction, moderate dilation and hypertrophy. Hemodynamic abnormalities in the left heart in these patients are closely correlate with the changes in the phase pattern of right ventricular systole and they turn out to be so greater as the degree of its hypertrophy is.

[Evaluation of the effectiveness of laser and drug therapy of patients with duodenal ulcer].

The paper presents clinical and morphological assessment of therapeutic response in 97 patients aged from 20 to 65 years with the diagnosis of duodenal ulcer from 1 to 15 years. Routine treatment was performed in 32 and drug therapy in combination with local He-Neon radiation of the ulcer was performed in 65 patients. Higher therapeutic response especially in those with the disease duration not longer than 5 years was revealed in case of laser therapy versus the routine drug treatment.
