[Inhibitors of proton pump in the treatment of non-ulcer functional dyspepsia of the reflux-like type]. / Ingibitory protonnogo nasosa v terapii neiazvennoi funktsional'noi dispepsii pri refliuksno-podobnom variante.

The results of two treatment types of the patients with chronic gastritis and with non-ulcerative functional dyspepsia (NFD) at reflux-similar variant are represented. The patients received Omeprasol (Losec) or Rabeprasol (Pariet) accordingly 20 mg once per day in the morning, 30-60 minutes before the breakfast. The treatment course was 7 days. The investigations have shown the following: the level of acidity has decreased in all the patients treated by Rabeprasol, normal acidity is detected in the all 15 patients, the level of gastric acidity has decreased in the patients, treated by Omeprasol. However the hyperacidity was preserved in 10 from 12 patients.

[Crimean-Congo hemorrhagic fever in Rostov Province: the epidemiological characteristics of an outbreak]. / Krymskaia-Kongo gemorragicheskaia likhoradka v Rostovskoi oblasti: épidemiologicheskie osobennosti vspyshki.

The results of the epidemiological analysis of the outbreak of hemorrhagic fever which was caused by Crimean-Congo hemorrhagic fever virus and occurred during the period of July 3-19, 1999, in the Oblivskaya district of Rostov Province are presented. The specific epidemiological features of the outbreak have been determined. The possible versions of the appearance of the focus of infection and the role of Ixodes ticks in the circulation of the infective agent are discussed.

[The characteristics of cholera prevalence and of the performance of epidemic-control measures in small settlements of Dagestan]. / Osobennosti rasprostraneniia kholery i provedeniia protivoépidemicheskikh meropriiatii v nebol'shikh naselennykh punktakh Dagestana.

The present work deals with summarizing the experience obtained by the specialized antiepidemic brigade of the Rostov-on-Don Research Institute for Plague Control in the work on the liquidation of cholera in some regions of Daghestan with a view to discussing the problems of improvement of anticholera measures. The characteristic features of the epidemic process were its explosive character, sparseness of the foci of infection, the prevalence of its transmission through everyday contacts (family contacts and intensive tribal contacts) and essential delays in taking anticholera measures due to sudden appearance of outbreaks, remoteness of small settlements and the lack of manpower and means for carrying out anticholera measures at a given place and time, as well as delays in epidemiological analysis carried out by local health service bodies. Delays in carrying out such measures led to the spread of infection both within settlements and in the whole region and further in the republic. The epidemic process was complicated by the antibiotic resistance of V.cholerae strains circulating on this territory. All these factors formed specific epidemic situation which introduced amendments into the organization of anticholera measures.

[The characteristics of the antibacterial therapy for cholera in Dagestan]. / Osobennosti antibakterial'noi terapii kholery v Dagestane.

Wide circulation of antibiotic-resistant Vibrio cholerae strains again gives prominence to the problem of etiotropic therapy. The results of the treatment of 428 persons infected with V.cholerae (237 cholera patients and 191 Vibrio carriers) in different regions of Daghestan during the outbreak of epidemic in 1994 are presented. The main criterion of the effectiveness of antibacterial therapy was the determination of the percentage of bacterial relapses. The sensitivity of 118 V.cholerae strains to different antibacterial preparations was studied by the method of serial dilutions. After the clinical use of chloramphenicol 29.7% of bacterial relapses were registered, the in vitro resistance of V. cholerae being 32-64 mkg/ml. After the use of tetracycline 16.5% bacterial relapses were registered with in vitro resistance being the same. The use of the combination of these preparations gave 15% of bacterial relapses. Furazolidone gave 4.3% of bacteria relapses, while after the use of ciprofloxacin 2.8% of bacterial relapses were registered with in vitro sensitivity equal to 0.25-0.5 mkg/ml. Ciprofloxacin was recommended for the treatment of cholera patients and furazolidone, for the treatment of Vibrio carriers.

[Interaction of lipoproteins in blood serum with steroid hormones]. / Vzaimodeistvie lipoproteinov syvorotki krovi so steroidnymi gormonami.

Interaction of human and serum lipoproteins with steroid hormones (corticosterone and cortisol) was studied. Methods of fluorescence quenching titration and equilibrium dialysis were used for quantitative evaluation of VLDL, LDL and HDL glucocorticoid-binding ability. Association constants were found to be 0.6-2.0 x 10(6) M-1 for corticosterone and 4.0-8.0 x 10(6) M-1 for cortisol. The number of binding sites varied from 3 to 300 for different classes of lipoproteins.

[Role of the motor area of the cortex in the performance of the postural escape reaction]. / O roli motornoi oblasti kory v osushchestvlenii poznoi reaktsii izbavleniia.

It has been shown on three dogs that unilateral ablation of the cortical motor area temporally disturbs previously acquired and opposite to the innate postural escape reaction to electric stimulation of the contralateral forepaw by increasing its pressure on the support. After 3-4 months of repeated training, compensation is possible. Bilateral ablation of the motor cortex elicits stable and unreversible disturbance of the acquired reaction. In reorganization of postural coordinations, motor cortex functions are connected with the inhibition of innate coordinations preventing performance of the reaction.

[Conditioned reflex transformation of unconditioned flexion of the limbs of the dog into extension]. / Uslovnoreflektornoe preobrazovanie bezuslovnoi fleksii konechnosti sobaki v ékstenziiu.

In response to electro-skin stimulation of the left forelimb eliciting its flexion,--an escape instrumental reflex was elaborated in five dogs in the form of extension of the stimulated limb (pressure on the support), i.e. a reaction antagonistic to the inborn one. The reaction was elaborated due to conditioned transformation of the unconditioned flexion: the flexion became gradually inhibited and the new form of reaction, previously not inherent in the animal increased and became stable. Such transformation of one reaction into another is connected with the reorganization of inborn coordinations.

Sensory generalization in instrumental defensive reflexes in dogs.

Five dogs were preliminarily trained in the situation of classical defensive conditioned reflexes. The training sharply impeded the subsequent instrumental avoidance conditioning (with the stimulus applied to one leg and the avoidance movement accomplished by another leg). However, following the elaboration of the instrumental avoidance to one of the signals previously used in the classical situation, the other signals of the classical conditioned reflex evoked the instrumental avoidance reaction at once, without any preliminary training. When the animals which had been trained under "instrumental" conditions were brought back to classical situation they revealed an extreme inertness of manifestation of the instrumental avoidance reflex. In another experimental series the same dogs were trained to perform an escape reaction. When the stimulating electrodes were displaced to new receptive areas, most dogs made use of their previous experience and performed the acquired instrumental movement, thus escaping the electric shock.
