Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Biological and Medical Sciences Diploma thesis Candidate: Bc. Martin Květoň Branch of study: Specialist in Laboratory Methods Supervisor: prof. PharmDr. Petr Nachtigal, Ph.D. Title: Screening for systemic amyloidoses in endoscopic biopsy samples BACKGROUND Systemic amyloidoses constitute a complex and heterogeneous group of serious diseases that result from protein misfolding and whose common feature is the deposition of pathological protein substances (amyloid) in the extracellular space of tissues. Diagnostics of amyloidoses is based on histopathological examination of tissue samples and direct demonstration of the presence of amyloid deposits. The overall purpose of this diploma thesis was to create, apply and subsequently evaluate a screening program focused on systemic amyloidoses. METHODS In the first part of the experimental study, available staining techniques used for the detection of amyloid deposits in the tissue were compared. The second part of the experimental study consisted of performing screening examinations on endoscopic biopsy samples of the gastrointestinal tract. RESULTS Based on the results of comparison, a method employing the Sirius red F3B dye was chosen as a suitable screening technique....

Impregnation methods - silver stain -their importace in diagnostic and transplant patology
Květoň, Martin ; Semecký, Vladimír (advisor) ; Němečková, Ivana (referee)
Page 1 of 1 Abstract Martin Květoň Impregnation methods - silver stain -their importace in diagnostic and transplant patology Bachelor's thesis Charles University in Prague, Faculty of Pharmacy in Hradec Králové Medical bioanalytics The impregnating histological methods are based on saturation of tissue sections with metal salts. The most commonly used silver staining methods employ silver ions for impregnation. Product of those methods is elementary silver, reduced "in situ" to the specific tissue components. (Newman, and others, 1998) The aim of this thesis was to analyze the most commonly used impregnating methods, to show their use in diagnostic pathology and to present the methodics of those techniques. The secondary aim of this thesis was to evaluate their importance in routine histopathological practice. The introductions part contains general information about the impregnating methods and their use. General theoretical part deals with the principle of those methods, special part deals with the structures which are showed by using those methods, and with general description of histological process. Methodical part contains detailed descriptions of chosen silvering methods, and their results. Conclusions have shown that the aims of the thesis have been met and that the impregnating methods are an...
