Využití fytoterapie v chovu koní
HAVLÍKOVÁ, Natálie
The aim of this bachelor thesis was to conduct research on phytotherapy and herbs used in horse breeding and internal parasites and their developmental stages. Breed-ers are increasingly paying attention to the health care of horses, and for that reason they tend to use unconventional medicine, such as herbs. The research focused on monitoring the effectiveness of a herbal mixture by WILD HERBS s.r.o. which supports against internal parasites, and recommenda-tions for the use of herbs in horse breeding. Monitoring took place on a farm in Mažice, where horses received a mixture fed in several stages by a feeding machine. After feeding the mixture, a coprological examination followed. Large and small strongyles, horse roundworm and horse tapeworm were found in the monitored farm. A clear indication of the effectiveness of the mixture when fed was a signifi-cant reduction in EPG values compared to previous years, which was also the goal. The EPG value in 2022 was 273 which is a significant decrease compared to the previous year of 2021 when the average EPG value was 634. The difference in EPG values between seasons was not significant. The value is rather determined by the current weather or the arrival of a new horse in the herd and the resistance of indi-viduals to the infection. The mixture had a very favorable effect on most horses, but at some point, a few individuals had higher EPG values, which could have been de-termined by several other factors. The steps needed to support a partially parasite-free breeding include collecting faeces, dragging pastures and monitoring the level of parasitic infection, giving suitable herbal mixtures and using anthelmintics in case of heavy infection.

The effect of particle size on lactose compressibility
Havlíková, Natálie ; Ondrejček, Pavel (advisor) ; Svačinová, Petra (referee)
Charles University in Prague, Faculty of Pharmacy in Hradci Králové Department of: Pharmaceutical technology Consultant: PharmDr. Pavel Ondrejček, Ph.D. Student: Natálie Havlíková Title of Thesis: The effect of particle size on lactose compressibility It is known that the particle size of the compressed material plays an important role in the manufacture of tablets. It affects the properties of intermediate and final products. In this thesis the properties of tablets made of two lactose types, which were used as model fillers, were studied. These were Tablettose® 80 and Lactopress® Anhydrous. In both lactose types, five sieved size fractions of the particle size ranging from 9 to 346µm and their original unsieved mixture were used. The compaction forces ranging from 2 to 10kN were used for tablet preparation. Magnesium stearate was used for external lubrication. The evaluation of the prepared tablets was done mainly by using the pharmacopoeial methods. The evaluated parameters were friability, disintegration time and hardness. Furthermore, the elasticity of the tablets and the evaluation using the force-displacement method parameters were assessed. From the results of this work, it is not possible to unambiguously determine the advantage of one particular fraction size in the comparison to the...
