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....
