Mesenchymal stem cells and their regenerative and immunomodulatory potential
Brychtová, Michaela ; Lysák, Daniel (advisor) ; Horák, Vratislav (referee) ; Raška, Milan (referee)
Mesenchymal stem cells and their regenerative and immunomodulatory potential Abstract Mesenchymal stem cells (MSCs) possess multidirectional regenerative ability, which, together with their immunomodulatory potential, makes them promising cell type for therapy of wide variety of diseases. Despite ongoing research, which proved MSCs application to be safe, reported effect of MSCs administration on patients is not convincingly beneficial yet. In our work we focused on elucidation of MSCs role in regeneration of vital organs, heart and liver, where a large damage is life threatening for patients and any improvement in therapy would save many lives. Similar situation is in Graft versus host disease (GVHD), where MSCs immunomodulatory properties could be beneficial. Role of MSCs in heart regeneration was examined in vitro. Primary adult swine cardiomyocytes (CMCs) were co-cultured with or without swine MSCs for 3 days and morphological and functional parameters (contractions, current, respiration) of CMCs were measured. MSCs showed supportive effect on CMCs survival, especially at day 3 of the experiment, where in co-culture was significantly higher number of viable CMCs with physiological morphology and maintained function. Effect of MSCs on liver regeneration was observed in swine model of chronic liver...

The sex education as the part of the health education of adolescents
BRYCHTOVÁ, Michaela
The work deals with the investigation on the level of information of pupils of the prevention of sexually transmitted diseases. I selected the group from 11 to 15 years of age, which are elementary school pupils of 6th to 9th class. Elementary schools were divided into town schools (66 respondents) and village schools (48 respondents). I formulated two hypotheses. The first one, stating that the elementary school pupils from 11 to 15 years of age have no information about sexually transmitted diseases, did not prove true. The second hypothesis stated that the village elementary school pupils have less knowledge on the prevention of sexually transmitted diseases than the town elementary school ones. Neither this hypothesis proved true. I believe that there are no such differencies between towns and villages as they used to be.
