Resting energy expenditure in patients with chronic obstructive pulmonary disease II
Krčmářová, Veronika ; Kovařík, Miroslav (advisor) ; Hronek, Miloslav (referee)
Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Biological and Medical sciences Student: Veronika Krčmářová Supervisor of master thesis: PharmDr. Miroslav Kovařík Ph.D. Title of master thesis: Resting energy expenditure in patients with chronic obstructive pulmonary disease II The aim of this study was to compare the resting energy expenditure (REE) and nutritional substrate utilization among patients with chronic obstructive pulmonary disease (COPD) and control group. Previous studies have confirmed increased values of REE in COPD patients. On the basis of the increase of this parameter there was a loss of lean and muscle mass. The utilization of nutritional substrates in patients with COPD is not yet known. Our study by a total of 20 patients includes 11 patients with COPD, and 9 from the control group . The age of patients ranged from 55 to 71 years. Each patient was examined once. We determined the value of REE by indirect calorimetry and utilization of nutritional substrates. According to our results, there was an increase in REE in 82 % of patients with COPD, while only 33 % of patients from the control group was hypermetabolic. Comparing the results of REE between groups we observed REE increase by about 20 % in patients with COPD compared with the control...

Morphological and functional variability of secretory glands in cercariae of chosen trematode groups
Krčmářová, Veronika ; Bulantová, Jana (advisor) ; Mikeš, Libor (referee)
Trematodes are characterized by their complex life cycles that include definitive hosts and variable number of intermediate hosts. Transfer of the parasite from the first intermediate host to the other is usually realized by larval stage called cercaria. After finishing of their development within the first intermediate host, morphology and fate of these larval stages vary according to the way of infection of the next host. Some cercariae actively penetrate directly to their definitive hosts trough their body surface, other encystate in the outer environment where they wait in a form of metacercariae to be ingested by definitive host. Both of these ways can be combinated and cercariae encystate inside second intermediate host after they actively penetrate them. Exceptionally, cercariae do not leave the sporocyst in which they were developing inside the first intermediate host. They encyst there waiting for ingestion by the definitive host. Various types of secretory glands have been developed in cercariae for successful direct infection of next hosts, survival of parasite in adverse conditions of outer environment or for transformation of one larval stage to subsequent one. Variability in morphology and function of these secretory glands in cercariae is closely connected with differences in life...

Ultrastructural interactions of larval bird schistosome Trichobilharzia regenti and immune cells of hosts nervous system
Krčmářová, Veronika ; Bulantová, Jana (advisor) ; Hodová, Iveta (referee)
Trichobilharzia regenti is a neurotropic fluke belonging to family Schistosomatidae. Larvae called schistosomula migrate in the definitive hosts (anseriform birds) throuth the central nervous system (CNS) to their final location in nasal mucosa, where they mature and lay eggs. In contrast with that, the infection of accidental mammalian hosts (including human), is often stopped already in the skin immediately after entering the host. However, some schistosomula are able to reach CNS of experimentally infected mice, and survive there temporarily. Reaction to the CNS infection of mice is usually provided by microglia, astrocytes or the other immune cells infiltrated from the hosts blood. Parasite protects itself against the host reaction with its tegument. It does not serve only as mechanical barrier, but also as main secretoric organ that is capable of active immune evasion. Changes within CNS of the vertebrate hosts, caused by migrating schistosomula of T. regenti, were already described by routine histological and immunohistochemical methods. Till now, there was a lack of informations about interactions of immune cells of the host and the tegument of the parasite on ultrastructural level. To fill this gap in knowledge, two different methods were used: (1) imunohistochemistry in light and electron...
