Utilization of bees products in cosmetics
Kobza, Martin ; Bednář, Michal (referee) ; Zemanová, Jana (advisor)
This bachelor thesis is focused on the problem of utilization of bees products in cosmetics. The aim of this thesis was to elaborate a literature review focused on individual bee products, their properties and their utilization in cosmetics. Honey, beeswax, propolis, pollen, royal jelly, apisin are said to be the bee products. Properties, utilization, determination of kvalitative properties and aplication into cosmetic products of individual bee products are mentioned in this thesis. Beeswax is used in production of lipsticks, creams and for basis of smears (oily creams). Royal jelly is aplicated into lotions, face masks, lipsticks, night creams, hair waters, hydration preparations etc. Honey is used for preparation of shower gels, soaps, body milks, hydration creams. Propolis is added into creams, body milks, body lotions, shampoos, lipsticks, soaps and mouth sprays. Pollen has significant content of vitamins, aminoacids and other substances in nature form for cosmetics. These substances are important for nutrition, regeneration and hydration of skin. Apisin is used in pharmacologic preparations, like healing creams and smears.

Obranné reakce včel vůči přírodním toxinům
KAINZOVÁ, Klára
The aim of this master thesis was to describe the effect of honeybee venom on several physiological characteristics in the honeybees Apis mellifera themselves. They included the expression and level of vitellogenin in selected organs, AKHs production in CNS, level of dopamine in brain, fat body and Malpighian tubules, oxidative stress (the activity of catalase) and the structure of thoracic muscles in workers and drones. Results showed that the bee venom did not change the AKH level in CNS. However, the envenomation decreased the expression of vitellogenin in fat body, as well as the level of vitellogenin proteins both in fat body and haemolymph. Catalase activity was increased in the gut of workers but decreased in the gut of drones. The venoms application slightly increased dopamine levels in the fat body, brain and Malpighian tubules, but only in the fat body the rise was significant. Honeybee venom damaged the structures of myofibrils and mitochondria in the thoracic muscles of workers, however, co-application of the venom with AKH generally abolished this effect; situation in drones remains unknown.

Vliv přírodních toxinů na včelu medonosnou
KAINZOVÁ, Klára
The aim of this bachelor thesis was to describe the effect of honeybee venom on the activity of digestive enzymes (amylases, proteases, lipases), AKHs production in CNS, and level of nutrients (lipids, proteins, glycides) and vitellogenin in haemolymph of the honeybee Apis mellifera workers. Crude venom was applied into the honeybee body 24 hours before determination of the above mentioned characteristics. Results showed that the bee venom reduced the AKH level in CNS, increased activity of digestive enzymes in gut, and increased level of vitellogenin in haemolymph. Effect of the venom on nutrient level in haemolymph was variable - level of lipids and carbohydrates was enhanced, while level of proteins reduced.

Hormonálně řízená obrana proti hmyzím patogenům
BODLÁKOVÁ, Karolina
The aim of this bachelor thesis was to characterize the effect of one insect pathogen (entomopathogenic nematode Steinernema carpocapsae) and one venom (from the honey bee Apis mellifera) on digestive enzymes (amylases, proteases, lipases), and on adipokinetic hormone production in the brain of the cockroach Periplaneta americana . The experiments were done with the adult male and female cockroaches from a colony kept in the Insectary in the Institute of Entomology BC CAS. The pathogen/venom were applied into the cockroach body by injection 24 hours before the processing. After that the activity of digestive enzymes in the midgut, and AKH level in the brain were monitored. The results showed that the nematode has no effect on enzymes, and on AKH level as well. On the other hand, the bee venom partially increased the activity of digestive enzymes, but the role of AKH in this process in not completely clear.

The effect of individual components of bee venom on the human body
Spurný, Jakub ; Horníková, Daniela (advisor) ; Čapková Frydrychová, Radmila (referee)
The honeybee (Apis mellifera) uses the sting apparatus to defend itself. It consists of a sting's part and a part related to the production of poison. Bee venom is secreted by special venom glands of bees. The chemical composition of the poison is a mixture of amino acides, peptides and enzymes with the various (patho)physiological effects. Some components of bee venom, for example, cause the breakdown of red blood cells, inhibit tissue excitement, increase heart rate and mean arterial pressure or cause an allergic reaction. On the other hand, the same components of bee venom also show significant positive effects on the human body. These effects have been reported in some diseases of the nervous system (Parkinson's and Alzheimer's disease), the cardiovascular system (atherosclerosis), integument (Acne vulgaris) and in the treatment of oncological diseases. For this reason, the study of bee venom components and their potential use in the therapy of various pathological conditions and diseases is important. Key words: sting apparatus; bee venom; organ system; therapy

Studie antimikrobiálního účinku včelího jedu na druhy borelie z komplexu \kur{B. burgdorferi} sensu lato: izolace genu kódujícího antimikrobiální peptid melitin z jedové žlázy včely medonosné \kur{(Apis mellifera)}
DAVIDOVÁ, Marie
The incidence of tick borne diseases has drastically increased over the past few years. Control of tick borne pathogens, especially spirochetes from \kur{B. bugdorferi} sensu lato complex, is complicated due to a lack of vaccines against them. The emergence of bacterial strains to well established and widely used antibiotics has become a serious public health concern. Analysis of new classes of antimicrobial peptides became the subject of new investigation due to their efficacy against disease causing pathogens. Among possible candidates, melittin from honey bee venom is of particular interest. The aim of this work was to study the effect of whole bee venom on Lyme borreliosis spirochetes. The minimum concentration of the venom that possesed the inhibitory effect on borrelia growth was identified. The gene enconding melittin was isolated from bee venom gland and recombinant melittin was produced in bacterial expression system. The effect of recombinant melittin on live borrelia culture was studied.

Representation of bee products in the nutrition of adults in the Czech Republic
ZÁHORKOVÁ, Jana
Currently at the forefront of people's healthy eating and healthy lifestyle. Bee products are a source of healthy nutrition. In the framework of representation of bee products in the nutrition of adults in the Czech Republic was through a questionnaire addressed a group of 1,086 persons age structure over 18 years old, living permanently in the Czech Republic. It was found that the best known bee products in the adult population include honey (99 %), the second most famous product is the beeswax (93 %), and knowledge of other products gradually decreases in the number of propolis (81 %), royal jelly (77 %) pollen (59 %), bee venom (45 %), bee brood (22 %). The most common honey bee products. Its consumption is 0.6 to 1 kg / person / year, when its consumption rises in interest groups, such as the beekeepers to 1.5 - 5 kg / person / year and more. The most common use of honey is its direct consumption, which is the preferred liquid consistency and type of honey - blossom (nectar) honey.

Bee products and possibilities of their use
LUKÁŠKOVÁ, Jana
The target of my Bachelor?s Thesis is to describe the importance of Honey Bee and focus on bee products. With its pollination activity Honey Bee secures propagation of entomophilous plants, is involved in protection of environment and increases yield of arable crops. Honey Bee products have versatile use. Honey is a good quality food supplement. Bees wax and propolis are due to their properties an important material for cosmetic industry. Bee poison is used for hymenoptera allergy care. Pollen serves as an energy source and royal jelly is used for treatment of central nervous system.
