Vojtechovská, Daniela ; Pourová, Jana (advisor) ; Mladěnka, Přemysl (referee)
Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmacology & Toxicology Student: Daniela Vojtechovská Supervisor: doc. PharmDr. Jana Pourová Ph.D. Title of diploma thesis: Natural drugs in the treatment of dry cough. Cough is a natural protective reflex of the airways. It is one of the universal symptoms and one of the major reasons to see a general practitioner. The main causes of cough include inflammatory diseases of upper and lower airways of viral or bacterial origin. However, cough can arise as a consequence of more serious diseases. Antitussives used in conventional therapy of cough are reliable, but they have many restrictions and adverse effects. Phytotherapy, including the therapy of dry cough, is a current trend. Unlike conventional antitussives, using natural drugs in therapy has several advantages, such as treating the main cause of cough, better safety, fewer adverse effects (natural drugs lack central adverse effects). In addition, natural drugs do not induce drug dependence, have fewer drug interactions, the duration of their use is not so limited, and they are easily available. The aim of this Thesis was to summarize available information on the use of natural drugs in the therapy of dry cough, and to supply reliable pharmacological data which would support...

Study of the influence of natural drugs on estrogen receptor and confirmation of their effect in cell cultures
Elbelová, Jana ; Carazo Fernández, Alejandro (advisor) ; Pourová, Jana (referee)
Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmacology and Toxicology Student: Jana Elbelová Supervisor: PharmDr. Alejandro Carazo, Ph.D. Title of the diploma thesis: Study of the influence of natural drugs on estrogen receptor and confirmation of their influence in cell culture Estrogens are one of the main reproductive hormones in women. Their function in the human organism is mediated by the estrogen receptor (ER). Estrogens are involved in important physiological processes such as reproduction, bone metabolism and cardiovascular function. Long term elevated levels of these hormones may also lead to breast cancer development. Phytoestrogens are natural ligands of estrogen receptor widely found in dietary products. These compounds have beneficial properties in treatment of menopausal symptoms thank to their estrogenic activities but are able to function as antiestrogenic agents too. In addition, they may play a role in the development of other illnesses (breast cancer etc.). Therefore, they can be considered as a potential pharmacological tool for the treatment of estrogen-related conditions. Within this master thesis, a total of six compounds, two phytoestrogens and four of their more relevant metabolites, were chosen (genistein, daidzein, S equol, O...

The in vitro effects of selected fenolic substances on isolated rat vessels
Rajtmajerová, Iveta ; Pourová, Jana (advisor) ; Hrdina, Radomír (referee)
Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmacology & Toxicology Student: Iveta Rajtmajerová Supervisor: PharmDr. Jana Pourová, Ph.D. Title of diploma thesis: The in vitro effects of selected fenolic substances on isolated rat vessels Silymarin flavonolignans are endowed with various aspects. Recently their hepatoprotective effect has been discussed widely as well as their positive influence on the cardiovascular system. This diploma thesis is concerned with the vasodilatory effects of silybin-A, silybin-B, silybin-A + B and isosilybin-A on rat aorta. The aim of this study was to test the vasodilatory effect of selected substances. The dependence of aortic relaxation on the increasing concentration of tested substances was measured. Isolated Wistar breed rat aorta was used. DRC curves were created and EC50 values were assessed from the obtained values of vessel tension. The results were evaluated subsequently. The vasodilator potential of silybin-A and isosilybin-A is comparable; hence the position of the substituents may be irrelevant in having any impact on relaxation of the vessels. Different vasodilatory effects of silybin-A and silybin-B have been observed thus, the relaxation could be stereoselective. The testing of the equimolar mixture of silybin-A and...

Treatment of asthma bronchiale
Čudová, Martina ; Tilšer, Ivan (advisor) ; Pourová, Jana (referee)
Topic: Therapy of asthma bronchiale Author: Martina Čudová Bronchial asthma is a lifetime chronical inflammatory disease of the airways. Chronical inflammation is linked to bronchial hyperreaktivity and both lead to reversible and variable obstruction of airways. The prevalence of this disease has been increasing in recent years, mainly in children and teenagers, where asthma becomes the most frequent disorder. Asthma isn't curable, but thanks to opportune diagnosis and correctly configured treatment, the patient can be absolutely without difficulties. Conversely, untreated asthma leads to irreversible functional environments, which deteriorate the patient's performance and his quality of life. An important part of the treatment is preventive proceding, its goal is the avoidance of the patient's contact with triggers. Pharmacotherapy is devided into treatment of exacerbation, when alleviation drugs are used, primarily inhalational rapid acting β2-agonists and long-term anti-inflammatory therapy, there are drugs of choice inhalational kortikosteroids. The latest substances include the antileukotriens and monoclonal antibody against IgE (omalizumab).

Optimization of allergic asthma model in rats
Radová, Hana ; Pourová, Jana (advisor) ; Vopršalová, Marie (referee)
Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Pharmacology and Toxicology Mgr. Hana Radová ABSTRACT (thesis towards the PharmDr. degree) Optimization of allergic asthma model in laboratory rat The aim of this thesis was the optimization of allergic asthma model in laboratory rats as experimental animals. More specifically, based on the determination/quantification of the number of cells (neutrophils, eosinophils, macrophages and lymphocytes) in bronchoalveolar lavage of Wistar rats, we attempted to determine the optimal time interval (1 hour or 24 hours) needed for the manifestation of an adequate allergic reaction after antigen challenge. Subsequently, we compared Wistar rats with Brown Norway rats over this time interval, and more parameters in Brown Norway rats were examined, specifically the level of eosinophil peroxidase and proteins in bronchoalveolar lavage fluid. We evaluated the induction of the tested model in comparison with non-allergic animals. In conclusion, (1) the time interval of 24 hours after the antigen challenge is more appropriate for the assessment of the selected model of allergic asthma; the time of one hour was not sufficient for the development of the allergic reaction. (2) Considering all evaluated parameters, Brown Norway rats are more suitable...

Oxidative stress and its role in respiratory diseases
Zakouřilová, Jana ; Pourová, Jana (advisor) ; Melicharová, Ludmila (referee)
Free radicals are essential part of common physiological metabolic processes in the organism. They are involved in the protection of the organism from heterogeneous elements, participate in many chemical reactions, serve as substrates for a numer of enzymes, have a signal function, mediate vasodilatation and also participate in reproduction. However all these functions must be under continous and strict control of antioxidant mechanisms because free radicals are also highly reactive substances. Failure of antioxidant control mechanisms can give rise to or at least contribute to serious damage of genetic information, molecules, tissues or regulatory mechanisms. The purpose of antioxidant protection of the organism is to counteract the negative effect of free radicals, even during and ongoing disease. The system is extremely complex, its individual components cooperate and sometime are in synergy with one another. The overproduction of free radicals can participate in the pathogenesis of many diseases of the respiratory system (for example: COPD, asthma bronchiale, ARDS, lung cancer). In the treatment of the diseases with suspected overproduction of free radicals, antioxidants may also be administered during therapy. To achieve good results, exact assessement of the actual condition of the organism...
