|Abstract:||Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease characterized by synovial hyperplasia and the destruction of cartilage and bone with unclear morphogenesis of pathological changes in oral cavity. Simultaneously microcirculatory disturbance is important link of pathogenesis in many pathological conditions in oral cavity with inflammatory consequences. The aim of this study was to determine importance of microcirculatory disturbance of oral mucosa in modeling of rheumatoid arthritis. Experimental investigation has been performed with modeling RA on laboratory white male mice according to described before method. Investigated groups were formed according to severity manifestation as ankle changes using digital calipers measuring. The specimens of soft tissues of the oral cavity were stained with hematoxylin and eosin, according to van Gieson, according to Rego after the routine proceeding. Morphometric studies were performed with estimation of volumes of specific vascular density in microcirculatory bed, density of connective tissue in lamina propria and area of tissue with ischemia. It was detected that disturbance of oral mucosae microvasculature is formed in rheumatoid arthritis with strong correlation relationship between specific densities of microcirculatory bed vessels and rheumatoid arthritis severity (r=0.74). Development of ischemic area indicates strong correlation relationship between ischemic area and rheumatoid arthritis severity also (r=0.72) and it could be connected with changes in microvasculature (r=0.82). Development of sclerotic changes in the lamina propria of the mucosa could is characterized by increased area of connective tissue from 21.37±2.82% to 34.97±2.26 %.|
