Fibronectin of the thyroid gland in dogs at single and multiple muscle loads

Fibroneetin (FN) plays a role in the differentiation, growth, maintenance of normal morphology, proliferation and apoptosis of cells, their migration and spatial organization, ineluding due to remodeling of the vascular and nervous supply. The aim of the study is FN in the thyroid gland (TG) after various types of muscular activity. The control thyroid-intact male dogs (16) have no running. Six experimental groups include 67 dogs with different models of running (from a few minutes to a few months). Monoclonal antibodies were used to isolate FN. Sections of the right lobe of TG were digitizing and areas were measured after qualitative analysis. Areas of FN after single loads with middle running time and multiple loads (from one to three months) did not differ significantly from the control. Areas of FN in two groups (single loads with minimum running time and single loads with maximum running time) were more than in the control group and they are significantly different from each other...
