ABSTRACT

Abdominal obesity becomes very significant health’s problem, especially because it is connected with pathogenesis of cardiovascular diseases. Adipose tissue is not only a store of excess energy but a hormonally active system too. The substances produced by adipose tissue are adipocytokines. Two of them are leptin and adiponectin. Adiponectin levels are inversely related to the adiposity degree, despite of adipose tissue is only source of it. concentrations of adiponectin have been reported to be decreased in patients with coronary artery diseases, type II diabetes mellitus, hypertensions and dyslipidemia patients in some insulin resistant states. It takes part in processes regulate glucose and lipid metabolism and it has anti-inflammatory and antiatherogenic properties. Adiponectin has a potential protective ability towards to cardiovascular diseases. Positive correlation with degree of adiposity has been reported for leptin – hormone involved in the regulation of food intake and energy expenditure. Leptin exerts many potentially atherogenic effects. It has been reported to influence on arterial hypertension, endothelial dysfunction, platelet aggregation, insulin resistant and activation of sympathetic system. In this way it can play very important role in development of stroke. Recent studies suggest that adiponectin and leptin may play an important role in obesity-associated cerebrovascular diseases. There is still too little evidence to say that these two hormones are independent marks of ischemic stroke and confirm their role in stroke pathogenesis.
