B a c k g r o u n d: Tissue fixation is essential for biological sample examination. Many negative toxic effects of formaldehyde-based fixatives have forced us to seek alternatives for formaldehyde based solutions. It has been demonstrated that natural sweeteners can preserve small tissue samples well and that these solutions can be used in histopathological processes. However, their ability to preserve whole human organs are unknown. M e t h o d s: A total of 30 swine hearts were investigated. Th ree study groups (n = 10 in each case) were formed and classifi ed on the type of fixative: (1) 10% formaldehyde phosphate-buffered solution (FPBS), (2) 10% alcohol-based honey solution (ABHS), (3) 10% water-based honey solution (WBHS). Samples were measured before fi xation and in the following time points: 24 hours, 72 hours, 168 hours, 3 months, 6 months and 12 months. R e s u l t s: The WBHS failed to preserve heart samples and decomposition of tissues was observed one week after fixation. In half of the studied parameters, the ABHS had similar modifying tendencies as compared to FPBS. Th e overall condition of preserved tissue, weight, left ventricular wall thickness, right ventricular wall thickness and the diameter of the papillary muscle differed considerably. C o n c l u s i o n s: The ABHS may be used as an alternative fi xative for macroscopic studies of cardiac tissue, whereas the WBHS is not suited for tissue preservation.}, type={Artykuły / Articles}, title={Fixative properties of honey solutions as a formaldehyde substitute in cardiac tissue preservation}, URL={http://journals.pan.pl/Content/111705/PDF/FMC%201-19%208-Piatek-Koziej.pdf}, doi={10.24425/fmc.2019.128029}, keywords={formalin, heart anatomy, fixation, tissue preservation, natural sweeteners}, }
