Pharmacological modifications of potential signal systems regulating metabolism of adipocytes and hepatocytes and their influence on obesity
Hodis, Jiří ; Farghali, Hassan (advisor) ; Kršiak, Miloslav (referee) ; Otová, Berta (referee)
v anglickém jazyce: Thesis abstract: Background and aims: Both obesity and metabolic syndrome form severe health problems in the whole world. Nevertheless the armament of pharmacotherapy for both diseases remains unsatisfactory. We aimed our work to main organs in risk of the mentioned diseases -liver and visceral fat using hepatocytes and visceral adipocytes as model. We detected 3 main metabolic and signalization activities- glycogenolysis, Nitric oxide (NO) production and transcription of inducible NO synthase (iNOS) in hepatocytes, lipolysis, NO production and iNOS transcription rate in adipocytes. We directed our interest to combination of peroxisome proliferation activator receptor γ (PPARγ) agonist, antagonist and β3 adrenergic agonist in the culture of epididymal rat adipocytes in the first part of our work. While in the second part we investigated the influence of β and α adrenergic mimetics, adrenergic blockers in the culture of rat high glycogen content hepatocytes. Methods: NO production was detected under the active agents treatments by detection of NO oxidative products NO2 and NO3 in media. Glycogenolysis was measured as free glucose rise released by hepatocytes into the media. NOS transcription level was extrapolated after comparative polymerase chain reaction with reverse...

Vliv vybraných potravin na hladinu glykémie
Habánová, Veronika
The thesis deals with the measurement of glucose levels at regular intervals in a selected group of volunteers after the consumption of breakfast cereals in combination with milk products. The theoretical part is devoted to the basic components of the diet and their digestion and metabolism. It also deals with the regulation of blood glucose level, methods for measuring glycemia, disorders related to metabolism of carbohydrates and the concepts of the glycemic index, glycemic load. The aim of the practical part was to find out how your chosen breakfast cereal in combination with dairy products have an effect on blood glucose levels in a selected group of volunteers. 16 students of the Mendel university in Brno were attended the experimental measurements. The students measured on the InBody, in order to determine composition of the human body. The level of blood glucose was always measured in time 0 (fasting), 60, 90 and 120 minutes from the beginning of the consumption of the food. Statistically significant difference was shown from measured values of blood glucose in 60. and 90. minute between the glucose solution, and breakfast cereals (P < 0.05).

Hypoglycaemic conditions requiring rapid arrival of emergency services in South Bohemia
VACKOVÁ, Zuzana
This bachelor thesis deals with the hypoglycaemic states that is not only a complication for diabetes mellitus disease but there are other diseases such as Adisson's disease or congenital hyperinsulinism. Hypoglycaemia can be for some people life endangered state, mainly if the state is not recognized in time or if an effective therapy is not started. The rapid therapy is crucial and should be started within the first speared symptoms to prevent the state get worse. The thesis acquaints the reader with the major gland's anatomy that influences the glycaemia, then the pancreas and its function and its hormones function. The major hormones are insulin and glucagon. The both hormones have the main influence on the controlling of glycaemia in the body. However, they are not the only ones factors that influence the blood sugar level. In various literature sources, the different glycaemia values can be found. That is the reason why it is difficult to define the level of hypoglycaemic stat. The thesis includes several definitions of the hypoglycaemia that differ according to the physiological values mentioned in various sources. An important part of the thesis is the chapter about the clinical symptoms. In the chapter, most sources concur. The clinical symptoms can be varied, sometimes not enough specified. After a few first vegetative symptoms (unrecognized hypoglycaemia syndrome can missed them), disorders of consciousness from the conscious to the coma usually appears. The coma is a state when a patient does not react on the surrounding. The following chapter describes the process of hypoglycaemic diagnoses. The process is described both in health institutions and during the pre-hospital urgent care where the possibilities are restricted. The care is a necessary part of the state. If the patient is conscious and is able to cooperate, some sweet drink and some chocolate are the best opportunity for the first help. The ideal tool that could be used during the light type of hypoglycaemia is Glukopur. Glukopur is the pure powder glucose that helps to the body that do not have to split disaccharides as within the sweet drinks and bars. Another topic is the dangers of hypoglycaemia. The dangers include the development of dementia that is often connected with hypoglycaemic states, the brain's damage or the dangerous of the heart arrhythmia. The most serious danger that can appear is the death. The thesis describes the summary of medicaments that can cause hypoglycaemia. Hypoglycaemia can appear as a child inherited metabolic disorder or as hyperinsulinism. One of the chapters deals with this topic. The quantitative method data collection was used for the practical part of the thesis. The departures of The Emergency medical service in South Bohemian Region to the hypoglycaemic states during the year 2014 were searched. From the whole set of cases eight of them were randomly chosen and were described case interpretations that show the way of the emergency service intervention within the hypoglycaemic states. The case interpretations depict the patient's state before the arrival of the emergency service, the way of treatment and the patient's state after it. The evaluated indication by health operation centre is depicted in the following section. These indications do not have to be identical to real patient's state. One of the aims of the thesis was to map the most common factors of chosen hypoglycaemic states that were measured according to the NACA scale, grades IV.-VI. The data were gotten by the crew of The Emergency medical service in South Bohemian Region. The next one aim was to map the indications of the health operation centre and the following patient´s state according to the NACA scale.
