The condition of the protective barrier of the stomach in patients with duodenal ulcer associated and non-associated with H. pylori infection has been studied. The state of gastric mucosal barrier was studied in 72 patients with peptic ulcer disease association with H. pylori and 26 patients without H. pylori by determining the content of insoluble glycoproteins and its fractions in the basal portion of the gastric juice. In a comparative perspective the state of these indicators were studied depending on the association with H. pylori and the severity of the disease. In patients with H. pylori, damages of protective mucus barrier are characterized by the significant shortage of fucose, which is considered to be the main component of the insoluble glycoproteins. In patients without H. pylori, status of mucosal barrier is characterized by uniform and less significant reduction in the content of fractions of insoluble glycoproteins. In this patients the reduction of insoluble glycoproteins is not dependent on the frequency of exacerbation. The content of fucose in the mucous gel of gastric juice is a diagnostic criterion for determining the frequency of recurrence of the disease in patients with H. pylori infection., Abdujalol Vahabovich Yakubov, Nargiza Ihsanovna Pulatova, and Literatura
In this article, the results of the morphological study of the cerebral arteries in the patients with the hemorrhagic ischemic stroke on the background of metabolic syndrome were submitted. We established that under hemorrhagic stroke on the background of metabolic syndrome one could observe the atherosclerotic damages in the form of plaques, hyalinosis of vessels walls, destructive and necrotic changes of the middle coat of vessel wall, which are, in our opinion, the main reason in morphogenesis of hemorrhagic stroke. The atherosclerotic affection of the cerebral vessels with the lipidosis and fibrotic plaques in the vessel wall, which caused in disorganization of the vessel wall in the form intimae proliferation, structural reconstruction of the internal elastic membrane which resulted in narrowing of the vessel lumen and development of ischemia is the morphological basis for the ischemic stroke with the metabolic syndrome. Also diabetic microangiopathy with the development of the hyalinosis, vessels walls sclerosis, which provoked the microcirculatory and metabolism processes injury in the cerebral substance that complicate the disease course is the important factor of cerebral blood circulation damage., Natalia Chuiko, and Literatura
Aims: This is the first study carried out to describe the role of fetal microchimerism (FM) in the pathogenesis of uterine cancer. The prevalence and concentration of male fetal microchimeric cells (FMCs) were examined in endometrial tissues in relation to subtypes of uterine cancer, and the histological grade and stage of the tumor. FM occurrence was analyzed in relation to risk factors including hypertension, obesity, type 2 diabetes, dyslipidemia, age at cancer diagnosis and patient pregnancy history. The prevalence and concentration of FMCs were examined in endometrial tissues using real-time polymerase chain reaction, SRY and b-globin sequences as markers for male fetal FMCs and total DNA. The studied group involved 47 type 1 endometrial cancers, 28 type 2 endometrial cancers and 41 benign uterine diseases. Results: While the prevalence of FM was decreased only in type 1 endometrial cancer, compared to benign uterine disorders (38.3% vs.70.7%; OR = 0.257, 95% CI: 0.105 to 0.628, p = 0.003), FMC concentrations did not differ within examined groups. The lower FM prevalence was detected in low grade (grade 1 and grade 2) endometrioid cancer (38.3% vs. 70.7%, OR = 0.256, 95% CI: 0.105 to 0.627, p = 0.003) and in FIGO 1 tumors (40.7% vs. 70.7%, OR= 0.285, 95% CI: 0.120 to 0.675, p = 0.004). No correlation between FM prevalence or FMC concentrations and risk factors was demonstrated. Conclusions: A lower prevalence of male FM seemed to be associated with better prognoses in uterine cancer based on tumor subtype, histological grade and stage of the tumor. and Ilona Hromadnikova, Katerina Kotlabova, Petra Pirkova, Pavla Libalova, Zdenka Vernerova, Bohuslav Svoboda, Eduard Kucera
The Purpose of this study is to demonstrate the effectiveness of combined treatment for III AB stage of nonsmallcell lung cancer. Nonsmallcell lung cancer spread form treatment is disputable. Operation is not final solution. The combined treatment is being tested (in clinical trials) in this study. This article argues that a combination of treatment is a better option than that of a specific treatment. However, there is a need to find new effective options for combined treatment., Akhat Bukenov, Elena Gizbrekht, Ergaly Shauenov, Bekzhan Orazbayev, Kalmurat Razzakov, and Literatura
Objective: to analyze main clinical-statistical indices of spine and spinal cord injuries (SCI) and system of organization of medical aid to the victims. We conducted a cohort retrospective study of materials of medical institutions of Tashkent city. Medical records of patients and records of forensic examinations were analyzed. 242 cases of spinal cord injuries were studied. Over the last 10 years in Tashkent the frequency of SCI have been tend to increase, males and working-age people are dominated. In 60.9% of cases the injury was associated, in 36.2% - isolated, and in 2.9% - combined. Fallings from height and road traffic accidents were the main reasons for getting SCI. Lesions at cervical level registered in 45% of cases, thoracic level - 27.3%, at lumbar level - 27.7%, respectively. According to ASIA/IMSOP, full injuries were noted in 40.1% of cases, incomplete injures were in 59.9%. Overall mortality from SCI was 68.6%. study allowed to get in detail the clinical and statistical indicators of SCI in the region., Rukhulla Zabikhullaevich Khikmatullaev, Alisher Iskandarovich Iskandarov, Dildora Zabikhullaevna Khakimova, and Literatura
We aimed to investigate in detail the structural mutations after influence of actellic insecticide at different doses and different temperature conditions. We tested effects of single introduction of different doses of actellic: 48, 96, 192, and 384 mg/kg. Cytogenetic effect of actellic in bone marrow cells at different temperature regimens was studied. Following actellic administration, animals were being in two temperature regimes: normal (18-20°C) and high (37-38°C). After treatment with actellic, animals were kept within 1, 2, 4 and 8 hours at high temperature (37-38°C), i.e. in a thermostat (TV-80) with access of air. In experiments, the animals were divided into seven groups. The animals of the 1st group were administered actellic at a dose 384 mg/kg and kept under normal temperature until slaughtering. The animals of the 2nd group after administration of actellic were immediately placed in an environment with a temperature of 37-38°C. Animals of the 3rd, 4th, 5th, and 6th groups after treatment with actellic were transferred to conditions with high temperature, respectively, for 1, 2, 4 and 8 hours. The 7th group of mice was under normal temperature conditions without treatment with actellic. Our results have shown that in normal temperature conditions single exposure of actellic (384 mg/kg) did not affect the genetic apparatus of somatic cell, evidenced by the frequency of chromosome aberrations in bone marrow cells that were within the control levels. However, at high temperatures (37-38°C) the pesticide caused 6-fold larger number of chromosome aberrations in bone marrow cells, in comparison with normal conditions., Anvarjon Rakhmankulovich Shermuratov, and Literatura

Východiska: Pohybový projev zdravého organismu je charakterizován vysokou mírou variability provedení pohybového úkonu. Za situace vzniklé poruchy řízení, zejména v důsledku neurologických onemocnění, dochází v různé míře k fixnímu pohybového projevu, projevujícímu se omezením schopnosti pružné reakce na změnu zevních či vnitřních podmínek, působících v průběhu provádění cíleně zaměřené pohybové akce. Cíl: Zjistit rozdíly ve svalové aktivitě a variabilitě svalových souher akrálních a proximálních svalů během dosahu a úchopu u zdravých jedinců a u pacientů s hemiparézou. Metody: Experimentální soubor tvořilo 24 probandů po prodělané ischemické cévní mozkové příhodě (iktu) s pravostrannou hemiparézou. Kontrolní soubor tvořilo 30 zdravých probandů. Svalová aktivita byla zaznamenána pomocí povrchové elektromyografie v průběhu dosahu, úchopu a oddálení válcového a kulového předmětu. Rozdíly v hodnotách plochy pod křivkou záznamu jednotlivých svalů mezi experimentálním a kontrolním souborem byly statisticky vyhodnoceny pomocí T-testu pro nezávislé skupiny. Vztah mezi aktivitou svalů předloktí a svalů pletence ramenního byl hodnocen pomocí Spearmanova korelačního koeficientu pro neparametrické hodnoty. Výsledky: Byly zjištěny významné rozdíly v míře a počtu statisticky významných korelací akrálních a pletencových svalů. U souboru probandů s hemiparézou byla zjištěna statisticky významně nižší aktivita m. pectoralis major a naopak vyšší aktivita m. trapezius. Současně převažovala vysoká korelace m. pectoralis major a extenzorů zápěstí a prstů, na rozdíl od souboru zdravých probandů, kdy se vzájemné korelace akrálních a proximálních svalových skupin objevovaly nahodile, v menší míře a četnosti. Závěry: Výsledky ukazují na snížení variability svalové aktivity u pacientů s hemiparézou v průběhu úchopové funkce. Náhradou nedostatečné funkčnosti akrálních svalových skupin se stává relativně fixní „ko-aktivace“ s vybranými proximálními svalovými skupinami., Background: Movement of a healthy organism is characterized by a high degree of variability performance of a movement task. In a situation of a motor control lesion, mainly due to neurological disease, occurs in varying degrees to a fixed musculoskeletal manifestation. ere are manifesting in a limiting responsiveness to changing external or internal conditions during the task oriented physical action. Objective: To determine differences in muscle activity and variability between a muscle synergy of acral and proximal muscles during reach and grip in healthy subjects and stroke patients. Methods: e experimental group consisted of 24 probands aer ischemic stroke (ictus) with right-sided hemiparesis. e control group consisted of 30 healthy subjects. Muscle activity was recorded using surface electromyography during the performation of selected types of grips of cylindric and spheric objects. e differences in the area under the curve record of individual muscles between the experimental and control group were statistically evaluated using the t-test for independent groups. e relationship between the activity of the muscles of the forearm and shoulder girdle muscles was assessed using Spearman‘s correlation coefficient for non-parametric values . Results: ere were the significant differences in the size and number of statistically significant correlations distal and proximal arm muscles. In stroke group was found significantly lower activity m. pectoralis major and higher activity m. trapezius. At the same time the prevailing high correlation m. pectoralis major and extensor wrist and fingers, unlike the group of healthy subjectss, when the correlation distal and proximal muscle groups appeared at random, in a lesser extent and frequency. Conclusions: e results indicate a reduction in variability of muscle activity during grasp function of stroke patients. To compensate the lack of activity of acral muscles becomes relatively fixed „co-activation“ with selected proximal muscles., and Petra Bastlová, Ivana Barbora Frgalová, Barbora Kolářová, Milan Elfmark, Alois Krobot
