Induction of neuronal cell death by neurotoxin factors
Riljak, Vladimír ; Langmeier, Miloš (advisor) ; Kozler, Petr (referee) ; Herink, Josef (referee)
Using histochemical analysis (NADPH-diaphorase, Fluoro-Jade В dye and bisbenzimide 33342 Hoechst) we studied the influence of intraperitoneal administration of nicotine, kainic acid and combination of both these substances on hippocampal neurons and their changes. In experiments, 18- 25- and 35-day-old male rats of the Wistar strain were used. 30 minutes prior to the kainic acid application (10 mg/kg), animals were pre-treated with 1 mg/kg of nicotine. After 2 days, the animals were transcardially perfused with 4% paraformaldehyde under deep thiopental anaesthesia. Cryostat sections were stained to identify NADPH-diaphorase positive neurons that were then quantified in the CA1 and CA3 areas of the hippocampus, in the dorsal and ventral blades of the dentate gyrus and in the hilus of the dentate gyrus. Fluoro-Jade В positive cells were examined, in the same areas, to elucidate possibly neurodegeneration. Results have shown that nicotine administration brings about the increase of the density of NADPH-diaphorase positive neurons in CA1 and CA3 areas of the hippocampus and in the hilus of the dentate gyrus in 18-day-old animals, in 25-dayold animals in CA3 area of the hippocampus, hilus of the dentate gyrus and in the vevrtal blade of the dentate gyrus, in 35-day-old animals only in the CA3 area of the...

The Problems of Craniocerebrals Injury in Intensive Care
Jašek, Kamil ; Bartůněk, Petr (advisor) ; Kozler, Petr (referee)
The topic of this Thesis is the intensive care of patiens suffering from a craniocerebral Injury, such injuries contributing to high mortality and morbidity in patiens with trumas. The theoretical part of this Thesis gives a brief outline of the anatomy and physiology of the head and goes into a greater detail into the kinds of injuries, their symptoms, diagnostics, and treatment. The empiricical part hereof is produced in the form of case study and focuses on the intensive care of patients so injured. The chosen patient in the case was a jung man after a traffic accident who had suffered from a very serious craniocerabral injury. Monitored is his hospitalization from his reception to his release from the AR ward. The tenth day hospitalization is dealt with in detail.

Consequences of early ischemic hippocampal lesion in rats
Mátéffyová, Adela ; Kubová, Hana (advisor) ; Mareš, Jan (referee) ; Brázdil, Milan (referee) ; Kozler, Petr (referee)
Stroke is an important cause of neurological morbidity in infants and children, with an incidence of approximately 8 cases per 100000 per year (Giroud et af. 1995). In chi ldren, stroke is often under-recognized/unrecognized because of variation in the presentation, evaluation, and diagnosis. In many cases, asyrnmetry of reaching and grasping, failure to reach developmental milestones, or post-neonatal seizures that appear some months after the acute event are the only mark of previous stroke.

Using hislochemical analysis (NADPH-diaphorase) we have been investigating the influence of intraperitoneal administration of kainic acid, hypoxia and combination of both these factors on neurons of the hippocampus and on the primary auditory cortex in male rats of the Wistar strain. Kainic acid was administered to 12-day-old and I8-day-old animals, which were exposed to long-lasting repeated hypoxia from the 2nd till the 17th day of age in a hypobaric chamber (for 8 hours a day). At the age of 22, 90 and 365 days, the animals were transcardially perfused with 4% paraformaldehyde under deep thiopental anesthesia. Cryostate sections were stained to identify NADPH-d positive neurons that were then quantified in CA1 and CA3 areas of the hippocampus, in the hilus, dorsal and ventral blade of the dentate gyrus and in the primary auditory cortex. In 22-day-old animals with kainic acid administered 18th day of life both hypoxia and kainic acid increased the number of NADPH-d positive neurons in the hilus, CA1 and CA3 areas of the hippocampus and in the primary auditory cortex. On the contrary, kainic acid given to the hypoxic animals lowered the number of NADPH-d positive neurons in the dentate gyrus. In 90-day-old animals with kainic acid administered 18th day of life hypoxia and kainic acid given to both,...
