Quantification in descriptive and experimental study of functional
Tonar, Zbyněk ; Kočová, Jitka (advisor) ; Hach, Petr (referee) ; Míšek, Ivan (referee) ; Křen, Jiří (referee)
Dissertation abstract The dissertation thesis consists of seventeen papers dealing with quantitative histological assessment of vascular wall and with application of morphometry in atherosclerosis research as well as in biomechanics of elastic arteries. History of microscopic morphometry with an emphasis on stereology is reviewed in the Introduction. The principles of mathematical morphology and of stereological estimation of volume, surface, area, length, and numerical density of objects in tissue blocks are explained in the Methods. The key rules of unbiased sampling of histological series and designing morphometric studies are summarized. The distribution of the overall observed variance in biological experiments, its sources and management are discussed. Procedures necessary for three-dimensional reconstructions based on scanned histological series are described. We proved that inflammatory process was significant in patients with ruptured aneurysm of abdominal aorta (AAA). There were more pronounced inflammatory infiltrates in areas of neovascularization in ruptured AAA than in asymptomatic AAA patients. Histological findings were in agreement with higher cytosol cytokine levels (IL-6, IL-8, TNF-α), enhanced collagen III metabolism and degradation in ruptured AAA. We found lower volume fraction of the...
