The thyroid gland disorders are the contributing factors to the development of periodontitis. Despite the lack of works, discussing the hemoreological and calcium, phosphorus homeostasis disorders, resulting in the destruction of the tooth hard tissue mineralization, their authors confirm the unity of the microcirculation disorders and thyroid dysfunction. Our data also confirm this statement. We believe that the imbalance, caused by parathormone, leads to microcirculation disturbances not only locally, but also to all organs and tissues.

The present study was aimed at investigating the comparative +changes of the two most significant microcirculatory factors if microvascular blood flow, possibly producing severe disorders in blood supply to tissues in the diabetic patients – constriction of resistant arteries and the hemorheological disorders in the patients with the type 2 diabetes mellitus. By using direct quantitative and highly sensitive investigation techniques we found that insulin improves the blood rheological properties in the microcirculation altered during diabetes.

However, when the disorders are strongly pronounced, due to enhanced red blood cells (RBC) aggregation, e.g., during development of the feet diabetic gangrene, the insulin becomes inefficient. As to the arteriolar tone, it seems to play less significant role in the pathogenesis of microcirculatory disturbances in diabetic patients.[/su_animate]

ABSTRACT The aim of the present study is comparison of changes of principal hemorheological factors responsible for blood flow disorders in the microcirculation in patients with ischemic brain infarcts. It was found that in venous blood samples the erythrocyte aggregability (examined with a direct, highly sensitive, quantitative technique) was considerably more increased (by mean of 120%) than the blood plasma fibrinogen contents, blood plasma viscosity, and hematocrit which increased only by 23.7%, 7.4% and 3.6%, respectively, as compared to the same hemorheological factors in the healthy controls.
