The aim of this survey is to find out informations about the progress, diagnosis and treatment of this infection and public awareness of this disease. Methods: Questionnaire study among parents, whose children have ever been infected with Enterobius vermicularis. Results: Pinworm infection is the most common among children aged 4-7 years. Half of the children who visited a pediatrician were examined. In almost 25 % of the cases, the stool sample was collected. The children were treated mostly with prescribed medication, the parents rarely chose home-treatment. In one third of the cases, the other members of the household were infected too. In the half of the cases the whole family was treated preventively. The most common symptom is rectal itching (83 %). Complications are exceptional. 60 % of the respondents incorrectly think that it is possible to get infected with pinworms from animals. The respondents most commonly called enterobiasis a disease of dirty hands. Conclusions: The...

Medveďová, Martina ; Doleželová, Eva (advisor) ; Kovařík, Miroslav (referee)
Charles University, Faculty of Pharmacy in Hradec Králové, Department of Biological and Medical Sciences University of Barcelona, Faculty of Pharmacy and Food Science, Department of Biochemistry and Physiology Student: Martina Medveďová Supervisor: PharmDr. Eva Doleželová, Ph.D. Consultant: Dr. Francisco José Pérez Cano, Ph.D. Study program: Pharmacy Title of diploma thesis: The effect of dietary prebiotic supplementation on neonatal development in rats Human breast milk is considered a gold standard in infant nutrition due to its multiple evident benefits on human health. However, breastfeeding is not always possible for various reasons; thus, it is a huge challenge to provide infant formulae which best mimic the composition and effects of human milk. Prebiotics added to infant formulae may greatly contribute to these prospective notable improvements in infant nutrition. The aim of this study was to evaluate the effect of a novel dietary prebiotic supplementation (under patent) on growth, fecal consistency, and immune maturation in suckling rats. G14 Lewis suckling rats were distributed into 2 experimental groups (n = 21/group): reference and prebiotic group. Vehicle or the prebiotic was administered by oral gavage daily from day 2 to 16 of life. Animals were weighed daily and their size and...

Kvasnicová, Lucia ; Doleželová, Eva (advisor) ; Jirkovský, Eduard (referee)
Lucia Kvasnicová Effect of soluble endoglin on bile acids transport in livers Diploma thesis Charles University in Prague, Faculty of Pharmacy in Hradec Králové Pharmacy Background: Increased plasma levels of soluble form of endoglin (sEng) were observed in patients with hypercholesterolemia, cystic fibrosis associated liver disease, or hepatocellular carcinoma combined with cirrhosis. As there are not available data focused on functional aspects of sEng in the liver, the aim of this diploma thesis was to describe the effect of sEng on the mechanism of bile formation and transport of bile acids in the liver. Methods: In our study were used six months-old transgenic male mice overexpressing human sEng on CBAxC57BL/6J background (sEng) and control mice (n = 8, in each group). Expressions of transport proteins responsible for bile acids homeostasis in the liver at mRNA and protein level were assessed by qRT-PCR and Western blot. Results: High plasma levels of sEng led to decreased plasmatic levels of bile acids. mRNA and protein expression analysis revealed, that this change occurs due to posttranscriptional induction of canalicular transporters, Bsep and Mrp2. Expression of an efflux Mrp4 protein localized at the basolateral membrane of hepatocyte was decreaced, which explains the decreased plasma...

Drobná, Zuzana ; Kovařík, Miroslav (advisor) ; Doleželová, Eva (referee)
Charles University Faculty of Pharmacy in Hradec Králové Department of Biological and Medical Sciences Student: Zuzana Drobná Supervisor: PharmDr. Miroslav Kovařík, Ph.D. Title: Dynamometry as a prognostic and prediction marker Dynamometry is a method for measuring muscle strength. It is one of the methods of biomechanical motion analysis. There are two types of dynamometry. Isokinetic dynamometry is based on isokinetic muscle contraction. In this contraction, the muscles change their length. Isometric dynamometry is based on isometric muscle contraction. The length of the muscle does not change during the contraction. In my master thesis, 22 studies were included. Of this, 18 were engaged in a dynamometer, which measured muscle strength. Studies have been focused on prediction of short and long-term mortality, prognosis of hospitalized and severely ill patients, prediction of disease symptoms (cancer, chronic obstructive pulmonary disease, liver disease). I searched for studies according to the PubMed database. In 16 studies, it was confirmed that dynamometry can be used in the present time as a reliable diagnostic, predictive and prognostic method. Dynamometry is characterized as a simple, objective, non-invasive, easily transposable and reproducible method. Keywords: dynamometer, muscle...

Charles Univerzity in Prague Faculty of Pharmacy in Hradec Králové Department of Biological and Medical Sciences Candidate: Rebeka Klingová Supervisor: PharmDr. Petra Fikrová, Ph.D. Title of diploma thesis: Effect of soluble endoglin to endothelial cells in vitro Aim: We determined the effects of soluble endoglin on endothelial cells, by the means of inflammatory markers. The aim of the study was to point out the possible association of the soluble endoglin with endothelial dysfunction. Methods: For our study we have selected the human endothelial cells from umbilical vein - HUVEC. We have influenced the cells with soluble endoglin in two concentrations and at two different time intervals. The results were evaluated in the statistical program, in which we have compared the control group with influenced cells and two concentrations between each other. The expressions of inflammatory markers were analyzed on the level of mRNA, using the real-time PCR method. Results: Significant changes in the expression of markers were observed on the vascular and intracellular adhesion molecule at both concentrations compared to the control group. Increased values of transcription were available also for cyclooxygenase 2 and decreased values for cadherin 5 compared to the control group. Conclusion: Changes in...

Filipová, Petra ; Němečková, Ivana (advisor) ; Doleželová, Eva (referee)
Charles University in Prague, Faculty od Pharmacy in Hradec Králové Department of Biological and Medical Sciences Progression of endothelial dysfunction in heart in a mouse model of atherosclerosis Author of diploma thesis: Petra Filipová Supervisor: RNDr. Ivana Němečková, Ph.D. Backround: Atherosclerosis is a disease when atherosclerotic lesions are formed in vessels. It represents the major cause of the heart failure and stroke. The endothelial dysfunction, which has been recorded in a large number of animals, is considered one of the main causes of atherosclerosis. In our work we have focused on the detection of the endothelial dysfunction markers in the heart of the ApoE/LDLR double knock-out mouse model. Methods: We detected changes in the expression of eNOS, p-eNOS and HO-1 in two-months and eight-months old ApoE/LDLR double knock-out mice, which were fed standard chow diet. For the semiquantitative evaluation of the observed markers we used the Western blot analysis of the homogenated left ventricle. Results: According to our results there is no difference in the expression of eNOS, p-eNOS and HO-1 in the studied mouse model of atherosclerosis in relation to age. This might mean, that the endothelial dysfunction in the coronary vessels of these mice doesn't develop. However, for further...

Paclíková, Kristýna ; Doleželová, Eva (advisor) ; Cermanová, Jolana (referee)
Kristýna Paclíková Influence of resveratrol on bile flow Diploma thesis Charles University in Prague, Faculty of Pharmacy in Hradec Králové Pharmacy Background: Protective effect of resveratrol is shown in many experimental models of cholestasis, but its effect on bile production in healthy individuals has not been studied yet. As the use of resveratrol is frequent in population, the aim of this thesis was to investigate the effect of resveratrol on the bile flow in healthy animals and the clarification of the mechanism of this effect. Methods: Wistar rats (n = 6, in each group, weighing 280 to 320 g) were divided into two groups: control group (Control) and the group of rats administered with resveratrol (10mg/kg/day, p.o.) for 28 days (RES). In vivo clearance study was performed to analyze bile production. Analysis of mRNA and protein expression of the transport proteins was performed by qRT-PCR and Western blot. Results: Resveratrol led to a significant increase in the cumulative bile flow. Analysis of mRNA and protein expression of the transport proteins revealed that bile flow is changed due to posttranscriptional induction of canalicular transporters Bsep and Mrp2. Simultaneously, resveratrol led to induction of Mrp4 efflux protein, expressed at the basolateral membrane of hepatocytes....

Characterization of a synthetic leoligin derivative, with agonistic FXR and enhancing macrophage cholesterol efflux activity
Kovářová, Lenka ; Kovařík, Miroslav (advisor) ; Doleželová, Eva (referee)
Charles University, Faculty of Pharmacy in Hradec Králové, Department of Biological and Medical Sciences University of Vienna, Faculty of Life Sciences, Department of Pharmacognosy Candidate: Lenka Kovářová Supervisor: Pharmdr. Miroslav Kovařík, Ph.D. Consultant: Dr. Angela Ladurner Title of the diploma thesis: Characterization of a synthetic leoligin derivative, with agonistic FXR and enhancing macrophage cholesterol efflux activity Atherosclerosis is a pathologic multifactorial process triggering the development of cardiovascular diseases, which are the leading causes of death in the western world. The initial phase of atherosclerosis is characterized by the accumulation of lipid particles, mainly low-density lipoproteins (LDL) and macrophage-derived foam cells in large arteries, leading to the gradual thickening of the vessel wall. These progressive alterations elicit plaque formation, followed by rupture, thrombosis and finally can lead to a cardiovascular event. Reverse cholesterol transport is an important preventive mechanism, which ensures removal of excessive atherogenic lipoproteins from macrophages. This efflux is facilitated by ATP binding cassette transporters, mainly ABCA1 and ABCG1 and in part by scavenger receptor B1 (SR-B1). Several nuclear receptors, including PPARγ, LXRα and LXRβ...

Krejčíková, Veronika ; Nachtigal, Petr (advisor) ; Doleželová, Eva (referee)
Bc. Veronika Krejčíková The effect of GLP-1 (glucagon-like peptide-1) analogues on rat hepatocytes in vitro. Diploma thesis Charles University in Prague, Faculty of Pharmacy in Hradec Králové Specialist in Laboratory Methods Background: We observed the effect of liraglutide (LIRA; a GLP-1 analogue) on rat non-steatotic (ST-1) and steatotic (HF) rat hepatocytes in vitro. We also monitored its potential hepatoprotective effect on the cells damaged by acetaminophen (APAP). Methods: As a model for our experiments we used the primary cultures of rat hepatocytes isolated from the liver of male Wistar rats. For isolation of lean and fatty hepatocytes, we used rats fed by standard laboratory diet (10% energy from fat) and high fat diet (71% energy from fat) for 6 weeks. Hepatocytes were isolated by two-step collagenase perfusion. We used LIRA at concentrations of 1, 10 and 100 nmol/l on intact, ST-1 and HF hepatocytes; we also tested effect of LIRA on hepatocytes after exposure to 2.5; 3.75 and 5 mM APAP. After 24/20-hours incubation, we tested the activity of lactatdehydrogenase (LDH) in culture medium, the viability of hepatocytes, production of albumin, and level of MDA and ROS production. Morphological evaluation of cells was performed by using phase microscopy. Results: LIRA at tested concentrations...
