Use of some fractions of technical hemp in cosmetics and pharmacy
Pavlištíková, Nela ; Uhlířová, Renata (referee) ; Márová, Ivana (advisor)
Hemp is known as a versatile usable plant with many industrial applications including pharmaceutical industry. The subject of this bachelor's thesis was to characterize the fractions of cannabis produced during its processing and their applications in cosmetics and pharmacy. In the theoretical part the characteristics of the plant, its chemical composition and bioactive substances are worked out. In the experimental part, some metabolites present in hydrolysates of hemp flour and hemp sludge were determined. All fractions were obtained from the Santhica variety. In the samples the content of carbohydrates, lipids, polyphenols, chlorophylls, fatty acid profile, acidity number and iodine number were determined. Furthermore, antimicrobial activity of hemp hydrolysates was tested and fat numbers of the sludge samples were determined. Hemp soaps from hemp sludge and coconut oil were prepared and analysed by sensory tests too. Hemp flour hydrolysate was used in shampoo, which was tested on humans. It was demonstrated that all the materials used were safe and suitable for use. The prepared soaps showed a hydration effect when washing hands. Hemp shampoo application led to smooth and soft hair when washed.

Use of hemp and its products in cosmetics and pharmacy
Žáčková, Kristýna ; Skoumalová, Petra (referee) ; Němcová, Andrea (advisor)
Hemp is a versatile usable plant which can be found in almost all branches of industry, but also in medicine. The subject of this thesis is the determination of selected active compounds of technical hemp and its products and their possible applications in cosmetics and pharmacy. In the theoretical part is worked out the summary of active compounds including their effects in cosmetics and within medical use. In the experimental part were determined certain metabolites of hemp products, while as samples were used hemp flower, leaf, seed, flour, protein and two different hemp oils. There were also prepared creams with the addition of hemp oil in which the effects on the skin were assessed. In the analyzed samples was according to the character of the material determined the content of antioxidants, saccharides, proteins, lipids including the profile of fatty acids, vitamins and chlorophylls. It was proved that hemp flower is a better antioxidant than the leaf and contains higher amounts of all of the determined active compounds with this effect. Flour and protein which are made from the seeds have different percentages of individual studied compounds, because there is a different process for their production. The highest amount of saccharides is in the flour, hemp protein preparative consists of a 50 % of protein and in the seed was the highest lipid content. In the prepared hemp creams the moisturizing effects and the ability to prevent transepidermal water loss were observed.

Pupil´s experiences with marihuana at primary school in Havličkův Brod
DUBEN, Martin
Abstract This Bachelor paper deals with the subject of experience that pupils of basic schools in Havlíčkův Brod have of using marijuana. The theoretical section describes the cannabis plant and marijuana proper; its effects; the methods of use; and the detrimental impacts the drug has on health and personality. Moreover, the section tackles the issues of drug addiction development as the process is related to taking marijuana itself, tobacco products and other drugs. The author has also addressed (1) the possibilities available to prevent the addiction at all levels; (2) the risk factors predisposing children and youth to abuse drugs and experiment with them; and last but not least (3) the anti-addiction policy and the principle acts of the relevant legislation applicable in the Czech Republic. The paper aimed to map the use and misuse of marijuana and tobacco products; to reveal the ways, forms and intensity of using marijuana in the pupils of basic schools; and to disclose the reasons behind using the drug and the scope of using tobacco in the basic school pupils. The paper examines three hypotheses. Hypothesis 1 predicts that smokers of tobacco products will have wider experience of marijuana than non-smokers. Hypothesis 2 predicts that boys will have more extensive experience of using marijuana than girls. Hypothesis 3 predicts that the town of Havlíčkův Brod will have greater incidence of marijuana abuse than the rest of the Czech Republic. The qualitative survey that the paper relies on has been conducted through an anonymous questionnaire, where the sample of respondents has been chosen according to quotas, specifically with regard to the respondents' age, sex and their being pupils of the 9th form of basic schools in Havlíčkův Brod. To obtain information having the highest achievable validity and variability, the data were gathered in the different classes without any person of authority for the respondents being present. The data thus collected were then processed by the common statistical methods to prove the hypotheses true of false. Fifty nine percent of boys and 75% of girls were found to have experience of tobacco products. Marijuana was tried by 27% of boys and 21% of girls. The method of marijuana use encountered in both boys and girls was smoking, 26% and 18% respectively, and the reason mentioned most often by both boys and girls was curiosity, 18% in both cases. Twenty five percent of boys and 20% of girls admitted experience of marijuana and tobacco products, while 2% of boys and 2% of girls have experience of marijuana but not of the tobacco products. In the incidence rate of using marijuana Havlíčkův Brod with the figure of 24% keeps 1% below the Czech Republic average (25%).
