Charles University, Faculty of Pharmacy in Hradec Králové Department of Biological and Medical Sciences Study program: Medical Laboratory Technician Candidate: Eva Semerádová Thesis supervisor: Prof. PharmDr. Petr Nachtigal, Ph.D. Consultant: Jana Šimková, MSc. Title of bachelor thesis: Monoclonal gammopathy The aim of this thesis is to describe monoclonal gammopathy (MG) The bachelor thesis describes forms of this disease, its history, classification and variants of laboratory diagnosis. Interesting. Monoclonal gammopathy is characterized by the presence of monoclonal immunoglobulin in serum or urine. There are two main types of the disease - malignant monoclonal gammopathy (MMG) and monoclonal gammopathy of undetermined significance (MGUS). For the diagnosis of MG is essential to determine the presence of monoclonal immunoglobulin in serum or urine and to determine the extent of bone marrow lesion. Based on the risk factors (radiation, chemical carcinogens, genetic predisposition, virus dual intervention-theory) were taken into diagnostic tests as well those describing free light chains ratio, number of malignant cells and quantity of monoclonal immunoglobulin. The most commonly used diagnostic methods are electrophoretic methods because of their time- and cost-effectiveness. For the typing is...

Morphological alterations in kidneys in mice with high soluble endoglin levels
Vyskočilová, Martina ; Němečková, Ivana (advisor) ; Nachtigal, Petr (referee)
Masters thesis Morphological alterations in kidneys in mice with high soluble endoglin levels Author: Bc. Martina Vyskočilová Study program: Medical bioanalytics Charles University Faculty of Pharmacy in Hradec Králové Background: Endoglin (Eng) is a transmembrane glycoprotein also known as an accesory receptor type III for a TGF-β molecule which is expressed primarily on the surface of endothelial cells. Endoglin plays a role in vascular homeostasis, angiogenesis and cardiovascular development. Soluble endoglin (sEng) which is formed by a cleavage of an extracelullar part of a membrane-bound endoglin scavenges the TGF-β molecules in the serum and blocks their binding to the membrane-bound receptor. Soluble endoglin is considered as a trigger of an endothelial dysfunction which is associated with cardiovascular diseases and patogenesis of preeclampsia. The aim of this study is to describe possible effect of high levels of a soluble endoglin on kidney tissue of transgenic mice in comparison with kidneys of mice with low levels of a human soluble endoglin. Methods: Kidneys of twelve months old mice with high and normal levels of a human soluble endoglin on a standard laboratory diet were fixed in 4% formaldehyde, embedded in paraffin and sliced into 7 μm thin sections. One of these sections was...
Daunorubicin effects on atherogenesis in rabbits fed by cholesterol diet.
Vašinová, Martina ; Nachtigal, Petr (advisor) ; Němečková, Ivana (referee)
Daunorubicin (DAU) was the first anthracycline (ANT) antibiotic with impressive clinical activity in the treatment of acute pediatric leukemias. Later, it has been shown that anthracyclines have broad range of therapeutic activities against both hematological and solid tumors, including breast, ovarian and gastric carcinoma. On the other hand, ANTs are the most dangerous anticancer drugs with respect to cardiovascular toxicity characterized by mostly irreversible morphological changes and cell death. Indeed, ANTs are used also in patients with hypercholesterolemia so the effect on atherogenesis in blood vessels is of interest. Thus, we hypothesized that DAU treatment and cholesterol diet will aggravate atherosclerosis when compared to rabbits fed by cholesterol diet only. Twelve adult male New Zealand White rabbits were fed with cholesterol diet (0.2% cholesterol). Control group of rabbits (n=7) received saline i.v. once weekly for 10 weeks since the beginning of the 4th week, the second DAU group (n=7) received clinically relevant doses of daunorubicin (3 mg/kg, ≈ 50 mg/m2, i.v.). The systematic uniform random sampling was applied for the quantification of atherosclerotic lesions. The samples from aortic arch were taken for the evaluation. Serial sections of vessel (7 μm) were cut on a cryostat...
Diabetes mellitus diagnostics
Blizniaková, Michaela ; Nachtigal, Petr (advisor) ; Fikrová, Petra (referee)
The bachelor thesis deals with problematics of chronic diabetes mellitus which changes in glucose homeostasis occur. In the past, it was a very rare disease, but a gradual change in the way of life during the 20th century led to its rapid increase. The thesis describes the pathogenesis of the disease and distinguishes between different types of diabetes based on current etiological knowledge of its development and manifestation. Despite treatment with insulin, oral preparations and diet, patients with the diabetes are at risk of premature emergence of acute and chronic complications, which are also included in the work. The thesis is focused on laboratory investigative methods in the diagnosis of diabetes mellitus, which assess the general health of the patient and represent a substantial part in the discovery of this civilization disease. Key words: Diabetes mellitus, diagnosis, glucose, laboratory investigative methods

Charles University Faculty of Pharmacy in Hradec Králové Department of Biological and Medical Sciences Consultant: prof. PharmDr. Petr Nachtigal, Ph.D. Candidate: Barbora Matějková Title of Thesis: Evaluation of Cell Adhesion Molecules Expression in Mice Aorta in Animal Model of Non-alcoholic Steatohepatitis Background: The purpose of the thesis was to observe changes in the expression of ICAM-1 and VCAM-1 in mice aorta endothelium. The study compares results of a group of mice after the administration of a NASH inducing diet and a group of mice fed by a chow diet. Method: Two groups of C57BL/6 mice were used for this experiment. At the age of ten weeks the experimental group was transferred to a NASH inducing diet which contains 40 % of calories from fat and 0.2 % from cholesterol. In addition to this diet, the experimental group was fed by fructose and glucose dissolved in drinking water with the concentration of 42 g/l (called "FFC-type diet" - high saturated fat, high saturated fructose, high saturated cholesterol). This diet lasted for 25 weeks. The control group was fed by a standard diet for rodents (called "chow-type diet"). The obtained samples were analysed by immunohistochemical methods. For ICAM-1, the indirect three-step avidin- biotin complex method was used. VCAM-1 molecules were...

Charles University Faculty of Pharmacy in Hradec Králové Department of Biological and Medical Sciences Author: Petra Doležálková Supervisor: prof. PharmDr. Petr Nachtigal, Ph.D. Diploma Thesis Soluble endoglin effects on membrane endoglin signaling in mouse aorta. Background: The aim of this study was to observe and evaluate the influence of the long- term (12 months) effect of high levels of soluble endoglin on membrane endoglin signalization in the mouse aorta. Specifically, we observed and compared the expression of proteins endoglin, eNOS, and pSmad2/3 in control and a test Sol-Eng+ group of mice. Methods: Two groups of 12-months-old mice with a difference in the level of soluble endoglin were used in this study. Both groups were originated in the same line of transgenic mouse strain CBAxC57BL/6J and fed with ordinary laboratory diet. Western blot technique was used to analyse the expression of individual proteins endoglin, eNOS, and pSmad2/3. The concentration of human soluble endoglin and soluble form of VCAM-1 molecule was evaluated by ELISA analysis. Total cholesterol levels and triglycerides in the plasma were detected by biochemical analysis. Results: Western Blot analysis showed no statistically significant differences in the expression of the membrane endoglin, eNOS enzyme and pSmad2/3...
