Study of interaction of antimicrobial peptides with cells in culture
Kroupová, Hilda ; Stiborová, Marie (advisor) ; Votruba, Ivan (referee)
In English The thesis deals with research of novel antimicrobial peptides (AMP) Halictines (HAL-1, GMWSKILGHLIR-NH2 a HAL-2, GKWMSLLKHILK-NH2) and their structural analogs isolated from the venom of the wild bee Halictus sexcinctus. The structure and antimicrobial activity of these peptides had been described earlier [1]. The goal of this diploma thesis is to find peptide which is strongly toxic only for cancer cells and nontoxic for normal cells. Using of the fluorescent marked peptides we aimed to acquire the information about mechanism of action of the studied peptides on the cells. Using the MTT test (determination of valuation IC50), the toxicity of HAL-1 and HAL-2 and their analogs against 2 normal cell lines (Human umbilical vein endothelial cells, HUVEC, and normal rat intestinal cells, IEC) and against 2 cancer cell lines (cancer cells of suppository uterine, HeLa-S3 and cancer cells of human colorectal carcinoma, CRC SW 480) was determined. First we tested antimicrobial peptides with antimicrobial activity and low hemolytic activity. For verification the toxicity of less active analogs was also determined. We found out that the HeLa-S3 cells are the most sensitive to these peptides. The most toxic peptides (HAL-1/9, HAL-1/18, HAL-2/2) kill 50% of cells in the concentration 2,5 - 10 µM. To obtain...

Methods of checking the observance of diagnostic reference levels in the field of radiodiagnostics
KROUPOVÁ, Helena
Methods of Checking the Observance of Diagnostic Reference Levels in the Field of Radio diagnostics Although there is a simultaneous development of diagnostic and therapeutic methods, perfection of instrumentation and means for personnel and patient protection, there is also an effort to reduce applied doses. In this way, medical irradiation caused by ionizing radiation used in medicine represents a significant contribution to the total dose of ionizing radiation that a person is exposed. Today the medical radiation in the Czech Republic comprises more than ninety per cent of radiation from an artificial source and approximately one ninth from the total population radiation. Evaluation of professional doctor radiation and X-ray devices attendance has been safeguarded within the personal dosimetry for many decades. However, systematic monitoring of doses related to medical radiation of the patient is a relatively new problem in the radiodiagnostics sphere. According to the Council directive 97/43/EUROATOM requirement, the SUJB has stated the so called ``diagnostic reference levels{\crqq} within enclosure number 9, Regulation No. 307/2002 Coll., about radiation protection. These ``diagnostic reference levels{\crqq} are dose levels within medical radiation and their exceeding is not expected at the 70 kg adult patient medical examination in the case of correct practice. The systematic exceeding of diagnostic reference levels under clinical practice conditions is the reason for reconsideration of radiation protection optimalization at a given workplace. In accordance with the proposal of the National Radiology Standards for Radiology Physics, the author team recommends the monitoring extension of the patient radiating load related to a particular medical radiation by specifying the local diagnostic reference levels, typical for a given type of workplace at a particular keeper, and their continuous verification within the clinical examination of the standard group of patients. Generally, the doses can be determined in two ways: by exposure parameter calculation or by product measure of area kerma, which is generally implemented by special devices, so called DAP meters. The aim of the work is the description of both methods, their comparison and the evaluation of the method effectiveness at various types of sciagrammatic workplaces.
