Unlabelled: THE PURPOSE OF THE REVIEW: Analyze the basic data on the role of obesity in the pathogenesis of pancreatic cancer (PC) and the modern mechanisms of this association.

Recent Literature Data: In the European Union and in Russia incidence of pancreatic diseases increases, such pancreatic cancer (PC) ranks 10th among cancer diseases. Obesity is a risk factor for not only of severe acute pancreatitis, but also PC at that independently of diabetes.

[Genetic aspects of pancreatic cancer].

The purpose of the review--to analyze the basic data on modifiable and genetic risk factors of pancreatic cancer (PC). PC is the most fatal disease that kills about 95% of patients. Among the known risk factors for PC only for smoking, obesity, and family history a positive association with the PC risk in meta-analyzes confirmed.

[Ability of winter wheat plants to become hardened against frost related to peculiarities of carbon dioxide exchange, biomass synthesis, and various forms of water-soluble carbohydrates].

The donor-acceptor relation (DAR) in a plant under cold exposure to frost was studied in the plants of winter wheat (Triticum aestivum L.) Mironovskaya 808 cultivar and its allocytoplasmatic hybrid containing alien cytoplasm of goat grass (Aegilops ovata L.) and grown in a water culture until phenophase, from two leaves until branching.

[Specific features of source-sink relations in alloplasmic hybrid of winter wheat with alien cytoplasm of goatgrass with emphasis on resistance to low temperature stress].

We studied the influence of alien cytoplasm of spring goatgrass Aegilops ovata L. on some physiological parameters in winter wheat (Triticum aestivum L.), Mironovskaya 808, under normal conditions and in the case of modified source-sink relations.

[Vessel-platelet and coagulation components of hemostasis in patients with chronic tubulointerstitial nephritis].

Aim: To study vessel-platelet and coagulation parts of hemostasis system, their correlation with clinical characteristics and activity of chronic tubulointerstitial nephritis (CTIN).

Material And Methods: 128 patients 15 to 65 years of age with CTIN were included in the study. The diagnosis was confirmed morphologically in 42 patients.

[Role of NO-mediated mechanisms in post-irradiation changes of neurohormonal regulation of the heart function].

Investigations on isolated Langendorff-perfused rat heart have shown that after the impact of ionizing radiation in 1 Gy dose the myocardial contractility and relaxation are decreased. The inhibition of NO synthesis attenuates chrono- and inotropic responses of the heart and reaction of coronary vessels to norepinephrine (NE), increases negative inotropic and vasoconstrictor effects of carbamylcholine (CCh). In the irradiated animals the reaction of isolated heart to NE and CCh is decreased.

[Plasmic activity of phospholipid membranes in nephritis].

Aim: To study activity of plasmic phospholipid membranes (PPM) in patients with chronic nephritis (CN) as regards clinical-laboratory and morphological characteristics of the disease.

Material And Methods: 10 patients with chronic mesangial glomerulonephritis (CMG) and 4 patients with chronic drug-induced tubulointerstitial nephritis were examined. All the patients had moderate arterial hypertension including 5 patients with CMG combined with nephrotic syndrome.

[Forensic medical expert evaluation in connection with civil actions of patients complaining of improper dental care].

The authors discuss questions facing forensic medical experts in connection with civil "medical" actions. The questions are classified as common and private. Expert evaluations of correspondence of the scope and quality of dental care are offered as the base for analysis of these problems within the framework of civil legislation.

[A comparative study of Coxiella burnetii strains differing in virulence in the intratracheal infection of guinea pigs].

As found out in earlier investigations, after the intratracheal infection of guinea pigs with C. burnetii (the method of infection, most similar to aerogenic infection which is characteristic of Coxiella under natural conditions) the maximum amount of the infective agent is accumulated in the lungs of the animals, damaging the organs of the reticuloendothelial system. The present investigation has revealed that this method of infection makes it possible differentiate C.

[An experimental study of the immunogenic and protective properties of Coxiella burnetii strain M-44 and a live enteral vaccine against Q fever].

High effectiveness of C.burnetii strain M-44 was confirmed in experimental studies on subcutaneously immunized guinea pigs ¿correction of pig] after their intratracheal infection with the virulent culture of the infective agent. The study revealed that the dose necessary for the enteral immunization of guinea pigs and monkeys was 10(4.

[Diagnosis and treatment of DIC syndrome in patients with severe craniocerebral trauma].

The hemostasis parameters are compared in 32 patients with slight (14-15 Glasgow score) and 114 with grave craniocerebral injury (3 to 7 Glasgow score) on days 1, 3, 5, and 7 after the injury. Assessment of hemostasiograms revealed a regular development of disseminated intravascular blood coagulation (DIC) in patients with grave craniocerebral injury, whereas in patients with slight injury the changes in the hemostasis system were compensatory. Early (starting from day 1) addition of anticoagulants, disaggregants, and fresh-frozen plasma to treatment protocols are advisable for patients with grave craniocerebral injuries.

[The pathogenesis of Q fever in the intratracheal infection of guinea pigs].

The intratracheal introduction of R. burnetii is the method of infection, highly similar to aerogenic infection, the most widespread route of R. burnetii infection in humans under natural conditions.

[Role of the body of the skate in initial processing of electroreceptor system signals].

Possible space mechanisms of information conversion processes with Lorenzinian ampullary apparatus during detection of the dipole electric field were studied using mathematical modelling methods. The stationary voltage distribution in the nonuniform media was calculated by numerical methods. The skate body was simulated by a thin disk.

[Pyocin production by bacillus pyocyaneus and sensitivity of strains of different origin to them].

Using the method proposed by Gillies and Govan and their indicator strains, 342 P. aeruginosa strains isolated from the patients were studied in respect to their pyocinogenicity and typed according to the production of different types of pyocins. Besides, in 206 cultures the pyocin sensitivity of 16 standard P.

[Effect of chronic alcoholic intoxication on the body of rats].

Experiments involving chronic introduction of ethanol (36 per cent of caloric value) as a part of a specially devised liquid ration demonstrated the trainability of rats to sharply decrease, their antistress resistance to significantly decline, especially in rats kept on a low-protein diet. A general tendency toward a reduced activity of acetylcholinesterase in different sectors of the brain was revealed both in animals receiving alcohol against the background of a normal protein allowance and in those kept on a low-protein diet (when compared with the enzyme activity in animals maintained on a ration with a normal of protein).
