Influence of defined olfactory stimuli to selected physiological parameters
Mažárová, Silvia ; Pánek, David (advisor) ; Vláčilová, Ivana (referee)
Title: Influence of defined olfactory stimuli to selected physiological parameters Objectives: Comparing the effect of inhibiting and stimulating scents on the chosen physiological parameters during a 20 minute long inhalation. The thesis is searching for the possible affections to cardiovascular system and to reactibility of the neuromuscular system of the aromatherapy. Methods: 10 individuals participated on the trial, 5 females and 5 male. As the inhibiting scent we chose essential oil of Lavandula angustifolia and as the stimulating scent Rosmarinus officinalis. The observed physiological parameters was heart rate, blood pressure, present emotional state using the Visual Analogue Mood Scale by Stern, results of the Petries' test and standing on two scales test. The chosen application form of the essential oils was inhalation. The observed parameters were recorded before the application of scents, in the 10th and 20th minute of the application and 20 minutes after the end of application. We used the method of comparison. With statistical analysis we compared the results of the mentioned tests and diagnostic methods before and after application each of the odors. Results: We consider that Lavandula angustifolia and Rosmarinus officinalis have statistically significant effect to cardiovascular...

Sensory and sensitive dysfunctions in neurodegenerative disorders of the basal ganglia.
Kopal, Aleš ; Roth, Jan (advisor) ; Baláž, Marek (referee) ; Laczó, Jan (referee)
Complex functions of the basal ganglia are affected by numerous sensory and sensitive stimuli. In our studies, we investigated parameters of sense of smell and vision in neurodegenerative diseases of the basal ganglia - Parkinson's disease (PD) and Huntington's disease (HD). In the first study, we use Odourized Markers Test (OMT) to determine its applicability in PD patients, and to determine whether it distinguishes olfactory disorders between neurodegenerative and other disorders. Results show that OMT is applicable for PD patients and comparable to Sniffin' Sticks as it demonstrates gains of lower scores in PD patients compared to healthy subjects, but they do not differentiate other etiology of olfactory disorders. In the next study, we tested the pleasantness of odor stimulants in PD patients using New test of odor pleasantness (NTOP). We investigated suitability and validity of its use. We found that PD patients had lower odor rating score compared to healthy group correlated with Sniffin' Sticks and OMT. In the following study, we examined whether PD patients with visual hallucinations (PDH+) have structural retinal changes measured by optical coherence tomography (OCT) and functional retinal changes examined by 2,5% contrast sensitivity test compared to PD patients without hallucinations...
