Optical Methods to Evaluate the Contractile Function of Isolated Cardiac Myocytes
Vadkerti, Kristián ; Rychtárik, Milan (referee) ; Čmiel, Vratislav (advisor)
Diploma work is focused on basic characteristics of optical measuring methods commonly used to rate contactions of isolated heart cell and describes basic actions, that are connected with it. A camera record made by a microscope served as basis for optical measuring methods of contractions chosen by us, with using appropriate method elaborating and analysis of pictures used for detection of important part of cell structure. The suggested user application built-up in Matlab environment allows analysis and interpretation of contractional functions in two methodical ways.
Cardiac ischemic tolerance of hypertensive rats
Jelínek, Jan ; Neckář, Jan (advisor) ; Sotáková, Dita (referee)
The aim of this thesis is to summarize current knowledge about the influence of the ischemic- reperfusion injury at the myocard of hypertensive subjects. First part of this thesis is focused on the description of ischemia, reperfusion and changes in the myocardial metabolism during these processes. These changes in the myocardial metabolism are for example necrosis or apoptosis of the myocardial cells. The second part describes the currently known cardioprotective phenomena. This part also compares their effects. The signalization of preconditioning, the second window of preconditioning and the postconditioning are described here in more details. Third part is focused on the description of the risk factors connected to the ICHS and hypertension. It describes also classes of hypertension, clinical and experimental methods of hypertension treatment, description of the laboratory breeds of hypertensive rats. In the last part of this thesis I describe the influence of hypertension on the I-R injury in current laboratory studies. In the most studies spontaneously hypertensive rats (SHR) were used. As a normotensive controls Wistar-Kyoto rats were mostly used. For some other experiments transgenic genetic rats (TGR) were used. Powered by TCPDF (www.tcpdf.org)
