The influence of perinatal hypoxia on motoric development on laboratory rat and means of therapy
Vachovcová, Sylva ; Mareš, Pavel (advisor) ; Stuchlík, Aleš (referee)
Severe perinatal hypoxia represents a substantial brain injury in human newborns. This Diploma thesis is focused on long-term motor outcome of laboratory rat after moderate perinatal hypoxia. We described some behavioral test for detection motor development and presented the influence of perinatal hypoxia on central nervous system. We also discussed an effect of agonists and antagonists of adenosine A1 receptor in brain. The aim of an experimental part was an evaluation of long-term motor behavior in rats affected by perinatal hypoxia. To cause perinatal hypoxia we put pregnant female rats to a hypoxic (10% O2) normobaric room in 11th day of their gestation. The pregnant female rats stayed in hypoxic room until they gave a birth and 6 more days after birth with their litters. For classification of motor development we used battery of tests of motor coordination. These tests correspond to the level of development of the rat. Then a group of rats with perinatal hypoxia was treated by a single administration of an agonist of adenosine A1 receptor 2-chloro-N(6)- cyclopentyladenosin (CCPA) in postnatal day 14. The animals affected by perinatal hypoxia show motor deficits in 3 from 4 selected behavioral tests. Otherwise, this motor behavior was no longer detected in young adults. The rats affected by...

The affect of perinatal hypoxia on locomotor development of laboratory rat
Vachovcová, Sylva ; Mareš, Pavel (advisor) ; Slabý, Kryštof (referee)
Perinatální hypoxie je závažným problémem u předčasně narozených dětí i u dětí narozených v termínu. Představuje vysoké riziko behaviorálních a neurologických poruch, a přestože se současná neonatální intenzivní péče stále zdokonaluje, rozsáhlá mozková léze v důsledku perinatálního inzultu obnáší výrazný klinický problém. Studie na zvířatech jsou proto stále nezbytné. Model perinatální hypoxie u laboratorních potkanů tak představuje výzkumné pole, kde se popisuje řada neurologických defektů, jako jsou poruchy lokomočních dovedností a deficity kognitivních funkcí u nedospělých i dospělých perinatální hypoxií postižených zvířat. Jejich mozková tkáň může sloužit k histologickému rozboru pro určení rozsahu mozkové léze a mnohdy jsou u těchto zvířat zaznamenány růstové poruchy, které jsou často spatřovány u dětské mozkové obrny.

School in nature from spring to winter
MLSOVÁ, Martina
The bachelor's thesis "Outdoor school from spring to winter" deals with the influence of field teaching on the locomotor development of preschool children. Based on specialized literature its theoretical part summarizes the influence of the natural environment on the child's development. It describes the benefits of field teaching, it deals with the term "Outdoor school" nowadays and in the past and with the locomotor development of children. The practical part includes an elaborated yearlong project on an outdoor school focused on child's locomotor developmend locomotor actt. Suggestei ovitiesf the blocks in question were carried out and assessed in conclusion.
