    Abstract:
    Disturbances of lipids metabolism described in obese persons are important factor damaging vascular endothelium. Known markers of endothelium impairment are: von Willebrand factor (vWf), tissue plasminogen activator (t-PA:Ag) and thrombomodulin (TM). The aim of the work was to evaluate markers of the endothelial disturbance in the blood plasma of persons with obesity. The study was performed in the group of 50 obese persons (39 W, 11 M) aged 35-65 (means 48.8) years with abdominal obesity. The control group consisted of 30 healthy volunteers aged 25-56 (means 41.0) years. In the poor platelet plasma obtained from venous citric blood concentrations of TM, von Willebrand factor antigen (vWf:Ag) and tissue plasminogen activator antigen (t-PA:Ag) were determined using immunoenzyme-linked assay (ELISA). In the obese persons significantly higher concentration of vWf:Ag and t-PA:Ag in comparison to control group. Analysis of results obtained according sex showed that in the blood plasma of obese women TM concentration was significantly higher than in healthy women. Our study proved that in the blood plasma of obese men there are evidences of impairment of endothelial function as higher concentration of vWf:Ag and t-PA:Ag, but in the group of obese women as the increased TM concentration.
