AIM Detection of circulation of West Nile virus (WNV) on the territory of Saratov Region and prerequisites for formation of natural focus of West Nile fever (WNF), determination of the role of WNV in infectious pathology on the territory of the region. MATERIALS AND METHODS of organs of small mammals, birds, blood-sucking arthropods for the presence of(More)
Studying the sensitivity and specificity of enzyme-linked immunosorbent assay (ELISA) for the indication of Crimean-Congo hemorrhagic fever (CCHF) virus antigens and those of reverse transcription and polymerase chain reaction (RT-PCR) for the detection of CCHF virus RNA, and those of a intercerebral infection method in newborn albino mice systems for the(More)
The paper gives the results of a study dealing with the detection of the antigens of arboviruses of West Nile, Sindbis, Batai, Crimean-Congo hemorrhagic fever, a serocomplex of Californian encephalitis in the field material gathered in the Saratov Region in 2000-2006. The bloodsucking arthropods inhabiting the region were shown to be actively involved in(More)
The analysis of advantages and disadvantages of the technique and principles of the methods of small intestinal perfusion, used by various authors in the studies on resorption processes, provided grounds the authors to develop their own method. The system for infusion and aspiration by a combined probe is described. Details about the composition of(More)
The effect of previous fasting on the liver morphological changes and microsomal cytochrome P-450 and b5 content was studied in thioacetamide-induced (100 mg/kg) rat liver necrosis. Starvation for 48 hours immediately before thioacetamide administration aggravates the dystrophic and necrotic processes, as revealed by histology, electron microscopic(More)
In a present paper a problem of classification of Af f (2, R)-orbits' dimensions is considered on example of an autonomous two-dimensional affine differential system of first order. Methods of Lie algebras are used in the work, as well as methods of group analysis. Computer algebra systems " Bergman " and " Mathematica 5.0 " are widely used.
In 74 patients with porphyria cutanea tarda, 11 (14.9%) cases of beta-thalassaemia were found. The incidence of beta-thalassaemia in porphyrics is not greater than in non-porphyrics and it seems that beta-thalassaemia is not a factor triggering the development of porphyria cutanea tarda. The phlebotomy treatment is also a convenient method for porphyria(More)
The activities of lactase, sucrase, maltase and gamma-glutamyl transferase (gamma-GT) were determined in homogenates of rat jejunal mucosa 24 h after acute administrations of D-galactosamine (GALN) (1.855 mmol/kg; i.p. injection) and alpha-naphthyl-isocyanate (ANIT) (0.540 mmol/kg; given by gastric tube). The animals were fasted either 24 h or 72 h prior to(More)
