The effect of the intrathecal application of Baclofen on muscular spasticity
Chvátalová, Jana ; Kraus, Josef (advisor) ; Smékal, David (referee)
The aim of this thesis was to introduce the intrathecal baclofen delivery method and assessment of its efficacy on patients with severe spasticity. It is an invasive spasticity affecting method which uses an abdominally implanted programmable infusion pump connected with a catheter inserted in the spinal canal. The pump delivers baclofen to the cerebrospinal fluid (baclofen is the central myorelaxans). This method reduces adverse effects of the drug, however it is an invasive method, that can bring various complications. In the practical part, I evaluated one patient with spinal spasticity before and after the treatment initiation. The spasm frequency was decreased by 2 points. The muscular tone measured by the Ashworth scale was decreased by 0,5 point, by 0,7 according to the modified Ashworth scale. Powered by TCPDF (www.tcpdf.org)

Postnatal development of GABAb-receptors in the frontal rat brain cortex
Kagan, Dmytro ; Svoboda, Petr (advisor) ; Langmeier, Miloš (referee) ; Mareš, Pavel (referee)
In this work, the detailed analysis of GABAB-R/G protein coupling in the course of pre- and postnatal development of rat brain cortex indicated the significant intrinsic efficacy of GABAB-receptors already shortly after the birth: at postnatal day 1 and 2. Subsequently, both baclofen and SKF97541-stimulated G protein activity, measured as the high-affinity [35 S]GTPγS binding, was increased. The highest level of agonist-stimulated [35 S]GTPγS binding was detected at postnatal days 14 and 15. In older rats, the efficacy, i.e. the maximum response of baclofen- and SKF97541-stimulated [35 S]GTPγS binding was continuously decreased so, that the level in adult, 90-days old rats was not different from that in newborn animals. The potency of G protein response to baclofen stimulation, characterized by EC50 values, was also high at birth but unchanged by further development. The individual variance among the agonists was observed in this respect, as the potency of SKF97541 response was decreased when compared in 2-days old and adult rats. The highest plasma membrane density of GABAB-R, determined by saturation binding assay with specific antagonist [3 H]CGP54626AA, was observed in 1-day old animals. The further development was reflected in decrease of receptor number. The adult level was ≈3- fold lower than...
