Dependence of derived fibrinogen on values of DH from APTT and QUICK(PT) methods
Klus, Michal ; Zapletal,, Ondřej (referee) ; Škutková, Helena (advisor)
Hemocoagulation, blood coagulation, is an important indicator of hemostatic balance in the human body. There are many ways how to investigate blood clotting. In practice, next to the tests investigating time of coagulation cascade from view of internal way (APTT – activated partial tromboplastin time) and external way (PT – prothrombin time) is often used determining of fibrinogen concentration by Clauss method. Derived fibrinogen method determined fibrinogen concentration, too, by subtracting form the clotting curve in PT test. The reaction for Clauss method is not necessary here. Derived fibrinogen is not used much in practice. This is the reason, why the thesis related to this project will try to find relationship between concentration of fibrinogen and standard tests APTT and PT. Clinical data will be used for this.

Possibilities of use of food supplements in prevention and health care calves
PÁNIKOVÁ, Monika
The basis for a successful cattle production is the proper care taking of pregnant cows as well as a sufficient care taking of the new-born calves. During the last years, a big attention has been given to this area because the higher farming quality the higher economic benefits and the lower losses in meat and milk yield will be respectively. For this reason, an influence of different feed supplements (Lactovita, Biopolym, Homeopathics) on haematological and biochemical parameters as well as an effect on weight gain and amounts of microorganisms in new-born calves has been studied. The specific aim of this thesis is to evaluate an influence of these supplements on incidences of diarrhea, microbial activity and to assess its effect on selected haematological and biochemical blood parameters. Three experimental and one control group (ten calves per each) were set up in the chosen company. The experimental groups had a modified feeding ratio between the first and the fourth week of life the calves received either colostrum + 5ml "PVB" homeopathic or colostrum + 5 ml "Biopolym" prebiotics or colostrum + 1 pill of "Lactovita", while the control group received colostrum without supplement. The first day after birth, a blood sample and a microbial smear sample were taken. Second sample collection was carried out in the fourth week of life. The calves were weighed every week. Obtained data were processed graphically and in tables and were statistically evaluated. The influence of mentioned feed additives on weight gain and diarrhea occurrence was evaluated from the obtained results. The most of haematological and biochemical parameters have approximately the same values compared to those found by other authors. There were no significant differences in monitored parameters in the experimental groups compared to the control group. Furthermore, no influence was found on blood parameters. Only in case of zinc a significant difference was found between treated groups and control (p=0,0012). Changes between the treated groups (independently on control) were observed in haematocrit, total protein content, cholesterol, zinc and copper. Non-significant differences between the tested groups and control were found in haemoglobin, erythrocytes, leukocytes, glycaemia, urea, LF, GMT, phosphorus, calcium and magnesium. No impact of tested supplements was found on microbial composition. A positive effect of Lactovita, Biopolym and Homeopathic compared to the control group was found in case of weight gain. The obtained results show some positive trends which should be a subject for further research, where total amount of calves per groups is increased to reduce variability.

The problems of nursing care during the application of transfusion
PEŠKOVÁ, Radmila
Abstract Issues of nursing care when transfusing Current situation: A transfusion is putting whole blood or its complements (plasma; erythrocytes) into the bloodstream. The doctor who transfuses is responsible for transfusing. While transfusing, cooperation between the nurse and the doctor is important; any mistake can endanger the patient's health and life (Vyhnálek, 2003). When transfusing, the nurse's competencies include taking the patient's blood for blood type testing and cross testing, preparing equipment and a set, ensuring the venous access, ensuring blood compatibility and blood at the patient's bedside, monitoring the patient while transfusing, and keeping documents (Vokurka, 2005). The aim of the research: To determine issues of the nursing care of a patient requiring blood transfusion. In addition, to determine whether nurses observe the standard nursing procedure for patients requiring blood transfusion. Methodology: The empirical part of the bachelor's thesis was prepared on the basis of qualitative research data collection through interviews. The qualitative research was supplemented with observations of nurses using an audit technique.The results were processed using open coding. Codes were created using a pencil and paper and then divided into categories and subcategories. Participants: Interviews were intended for general nurses working at the surgical and orthopaedic departments of hospital České Budějovice, a.s. The interviews were conducted by agreement with the nurses in charge of the departments concerned. It was a deliberate choice that was influenced by the participants' willingness to cooperate. Sampling was terminated when the data obtained were theoretically saturated. An audit was carried out in the case of 5 nurses within the semester thesis. Results: It was found out on the basis of the research that the nurses had good theoretical knowledge in the area of the care of a patient requiring blood transfusion, but there were certain areas in which the nurses showed a weakness. The nurses showed their greatest weakness in the case of blood derivatives. There we found out from the research that the nurses were unable to explain what blood derivative was during the research. The results show that the nurses' knowledge in the area of patient care before transfusing is excellent. Another examined part of the research was to determine what duties the nurses had to perform while transfusing. There it was found out that not all nurses observed the recommended procedure for monitoring the patient while transfusing. The last part of the research was to find out what responsibilities the nurses had after transfusing. The research results show that the nurses know how to handle the completed transfusion and that they should keep it in a special refrigerator for 24 hours. After the end of transfusing all the nurses interviewed also measure the patient's physiological functions and then record them in the nursing documentation. Furthermore, it was discovered by the research that the longer practice nurses have and the more often they meet with transfusing, the less danger of damage to the health of the patient is. The results of the audit of transfusing show that the most frequent mistakes the nurses made were the insufficient identification of the patient, failure to observe the recommended time of application, and the unsatisfactory checking of the patient's condition while and after transfusing. Conclusions: The research results show that the nurses interviewed have relatively wide knowledge of the issues concerned. They know the nursing care of a patient requiring blood transfusion before, while and after transfusing. The research shows that the more often the nurse meets with transfusing the better her skills in transfusing are. The research proved that although the nurses knew the standard nursing procedure for a patient requiring blood transfusion, in practice they did not observe it fully.

The Motif of Vampire in Czech Literature
RICHTROVÁ, Tereza
The thesis focuses on the presence of the motif of vampire in Czech literature from the end of the 19th century to the end of the first half of the 20th century. The motif is formed by a set of vampire attributes and the aim of the thesis is to observe changes of its image depending on its application and function in particular pieces of work. The observation comes from mythological and traditional conceptions of the vampire character which defined the image of the creature. The attention is also focused on the period trends influencing literature in general and on the application of the motif in foreign literature. The thesis marginally refers to its presentation in the visual arts.
