[Structure of venular vessels and cellular composition of hepatic sinusoidal capillaries in newborn infants].

The objective of this study was to identify the structural peculiarities of terminal interlobular venules and to determine the number of endotheliocytes, hepatic fat-storing cells (FSC) and stellate macrophages (SM) in the liver of newborn infants. Liver fragments were obtained from 5 healthy newborn infants during medico-legal autopsies. In the sections stained using Mallory's method, the relation of the connective tissue of terminal portal tracts with the adventitia of interlobular veins was determined.

The work studies effects of various doses of oxytocin (0.01, 0.1, 1 and 10 microg/kg) on duration of discharges of spontaneous electrical activity and frequency of spikes in various parts of uterine tubes and of uterine body of non-pregnant rats.

[Repeat endovascular interventions after transjugular intrahepatic portosystemic shunt (tips) procedures].

The authors share their experience with transjugular intrahepatic portosystemic shunt (TIPS) procedures preformed in a total of fifty-nine patients diagnosed with and hence operated on for class B and C hepatocirrhosis (according to the Child-Turcotte-Pugh classification), portal hypertension, grade 3 varicosely dilated oesophageal veins, or ascites. Of these, there were 12 women and 47 men (average age 56.3 years).

Carboxyangiography: a new type of opacification in angiographic practice--first clinical experience.

The study was undertaken to investigate a possibility of clinical application of medical-purpose CO2 as an alternative radiopaque agent (RA) for visualization of major arteries and veins. During the period from April 2009 to June 2010, a total of fifty 38-to-72-year-old patients (mean age 58 years) underwent angiographic examinations wherein medical-purpose CO2 was employed as a radiopaque agent. We performed 39 aorto-arteriographies, 10 portographies, and one mesentericography.

[Urolithiasis morbidity in Tadzhikistan regions: some biogeochemical and environmental factors].

The aim of the study was to investigate urolithiasis prevalence in the main administrative regions of Tadzhikistan, to ascertain effects of drinking water quality, water pollutants and other environmental factors on urolithiasis morbidity in endemic regions of Tadzhikistan. It was found that high urolithiasis incidence rate in some regions was associated with high water pollution (class III and IV), its high natural mineralization and hardness, high content of chlorides, sulphates and other components of salt composition, organic and non-organic pollutants. Chemical and microbiological tests showed that sanitary standards were not strictly observed in the regions with high urolithiasis morbidity.

[Potentialities of current methods for laboratory analysis in the evaluation of the severity and prevalence of nephrolithiasis in Tajikistan].

The investigation was undertaken to study a relationship between some biogeochemical and environmental factors and nephrolithiasis morbidity rates in the regions of Tajikistan. The paper presents the data of an integrated examination involving biochemical, chromatographic, and mass-spectrometric studies of 1180 patients aged 14 to 76 years who have been treated at the Dushanbe Urology Medical Center. The investigation established a relationship of an increase in ICD morbidity in poor environmental regions of the Republic of Tajikistan to the high organic and non-organic pollution, the high natural mineralization and hardness of water, and the elevated levels of chlorides, sulfates, and other salt components, which in turn influences the severity of a pathological process.

[Chromatographic mass spectrometric assessment of the course of different forms of urolithiasis].

The study has been undertaken to improve the methods for diagnosing urolithiasis, which comprehensively evaluate the severity of a pathological process and the results of treatment in patients with nephrolithiasis. The paper gives the data of investigating the processes of chromatographic mass spectrometric urinalysis in 82 patients aged 15 to 81 years urgently admitted to the units of urology of Moscow City Clinical Hospital Seven for a renal colic attack. The levels of lithogenic substances were measured in patients with different types of metabolic disturbances.

[Rheolytic catheter-assisted thrombectomy in a gigantic floating thrombus].

Thrombosis of deep veins of the lower extremities is a serious and frequently occurring disease (with the incidence rate of 160 newly onset cases per 100,000 people annually). A great number of complications are known to develop in case of the ileofemoral thrombosis and a floating pattern of the proximal portion of the thrombus, especially if extending to the vena cava inferior. Appropriate treatment of thromboses of the vena cava inferior should consist in averting dissemination of thrombosis in the proximal direction, preventing pulmonary-artery thromboembolism (PATE), and restoring the patency of the vena cava inferior in order to eliminate the risk of post-thrombotic disease.

[Morphofunctional state of the blood microcirculatory bed in the injured gastrocnemius muscle in rats during pharmacological stimulation].

The state of hemomicrocirculatory bed and of local peripheral circulation was studied after the operational injury of rat gastrochnemius muscle without pharmacologic treatment and following a combined administration of alpha-tocopherol and methyluracil. Local circulation in the regenerate of the treated animals was shown to increase not only as a result of increase of capillary density, but also due to the elevation in the number of functioning capillaries and veins.

[Dual reciprocal regulation of the succinate oxidation system in heart and liver mitochondria in pathological conditions].

The phenomenon of the dual reciprocal regulation of succinate dependent 2H+/Ca2+ exchange was studied in heart and liver mitochondria of experimental animals (allogenic heart transplantation in rat; myocardium infarction in rabbits; pulmonary arteria coarctation in dogs) and in liver bioptates from patients with stomach ulcer. Under pathology two coupled but opposite changes (simultaneous activation and inhibition) in succinate dependent Ca2+ transport occur. The inhibition of Ca2+ transport was detected by its elimination with glutamate, being mostly pronounced after cycle of ADP phosphorylation added to suspension of mitochondria.

[The effect of calcium antagonists on the rate of gastric emptying in patients with duodenal peptic ulcer and the dumping syndrome].

Comparative evaluation of single-dose finoptin, corinfar and falicor by effect on gastric evacuation was conducted in 33 peptic ulcer and 48 postgastrectomy dumping syndrome patients. Finoptin was found to prolong the evacuation in contrast to corinfar which stimulated it. Nonsignificant delay in gastric evacuation occurred in falicor administration.

[Effects of wheat bran on the rate of gastric stump and small intestine evacuation in patients with dumping syndrome after stomach resection].

A total of 65 patients with dumping syndrome after gastric resection were under study. It has been found that addition of 10 and 20 g of wheat bran to semolina porridge significantly (p less than 0.05) inhibits the rate of gastric stump and small intestine evacuation, and in 1/3 of the patients it promotes lowered manifestation and duration of dumping syndrome.

[Effect of different types of food loads on the rate of emptying of the gastric stump in patients with the dumping syndrome after gastric resection].

The influence of carbohydrate, carbohydrate-fatty and protein test breakfasts on the rate of gastric stump evacuation was studied in 62 patients with dumping syndrome of mild and moderate severity, using the x-ray method developed by the authors. It has been established that in patients with dumping syndrome carbohydrate and carbohydrate-fatty food is most quickly evacuated from the gastric stump. Doubled amount of fat in the carbohydrate-fatty breakfast (up to 40 g) induced no significant deceleration in the gastric stump evacuation, moreover, in some cases its evacuatory function was accelerated.

[Effect of adrenomimetic and antiadrenergic agents on the gastric emptying function in peptic ulcer patients].

Stimulation with isadrin and blockade with inderal of beta-adrenergic processes exert no significant effect on the time of food evacuation from the stomach. The alpha-adrenergic action of mezaton and ephedrine manifests itself in delayed food evacuation from the stomach at its initial accelerated evacuatory function. Blockade of alpha-adrenoreceptors with pyrroxan reduces the time of the stomach evacuation at the initial delayed gastric evacuation.
