Thyroid and periodontitis

16Mantskava M.

 

The modern world is increasing every year the number of people with thyroid dysfunction. It is necessary to pay attention to the children (11-15 yars old).  5% of this population is patient with thyroid dysfunction. At this age, most developing first and second stage of periodontal disease. Population rheological studies suggest that periodontitis when compared with the control hemorheological status is changed to 15%,  that thyroid dysfunction when compared with the control hemorheological status is changed to 30%. Rheological status   in patients with thyroid dysfunction and periodontal disease is even more variability. The book details shows the effect of the formation periodontal disease during thyroid dysfunction.

Abstract. It could be conjectured that the hemorheological disorders are involved in development of the ischemic heart disease. But this fact was so far insufficiently cleared up. The present studies were carried out in patients with various forms of chronic ischemic heart disease. We investigated the most significant factor of rheological disorders in the microcirculation, the erythrocyte aggregability, which a technique that provided us with the direct and quantitative data. Simultaneously we investigated in the some patients the tone of the resistance arteries of the hand with an original non-invasive technique. We found that the erythrocyte aggregability increased almost twice in the blood of investigated patients as compared to the healthy control group. The aggregability was positively correlated with severity of the disease.

Abstract. Under both in vivo and in vitro conditions we investigated effect on the most significant factor disturbing the blood rheological disorders in the microcirculation, the red blood cell aggregability. The in vivo studies we carried out in the 42 insulin treated diabetic patients (diabetes mellitus type II), as well as conducted the in vitro investigations of the blood both of the diabetic patients (24) and of the healthy people (20) where the insulin was added to the blood in vivo.

Abstract. The aim of the present study was to evaluate blood rheological disorders, in particular RBC enhanced aggregation, and compare changes in these parameters in patients with type I and II diabetes mellitus. For evaluation of RBC aggregability in the present study we applied the “Georgian technique”, which was developed and applied for several years in our laboratory. Its advantage is that it is a direct and quantitative method. In all the investigated patients, diabetes mellitus was compared with the foot gangrenes. The patients were divided into two groups: (a) with type I and with type II diabetes mellitus. We matched the RBC aggregability indices in both groups of diabetic patients and compared the obtained results with those in the healthy control group. We found that rheological disorders were considerably pronounced.

Summary

Sleep apnea is an independent pathology and a powerful stress for the organism. Apnea affects different systems. 44 patients with obstructive apnea (age 45.4±5 years) were under observation. Control group consisted of healthy subjects aged 36.3±5 years. Rheological status in the group of patients was as follows: RBC aggregability index – 42.7±7.2, RBC deformability index was 2.23±0.06, plasma viscosity – 1.27±0.03 and Hct – 39±5. The same parameters in the control group were: RBC aggregability index – 25.0±3.0, RBC deformability index – 2.23±0.02, plasma viscosity – 1.25±0.02, Hct – 45±3. The obtained data allow to recommend clinicians include disaggregants in standard treatment of obstructive sleep apnea.

Blood loss is a complex pathological process with the mechanism that has not been fully unstudied. Blood rheology.biz is a particular link that is involved in blood losses. Objective: to perform a comprehensive study of blood rheological proper- ties, such as erythrocyte aggregability, erythrocyte deformability, plasma viscosity, and packed cell volume, in different degrees of experimental blood loss.

Stress – cause and effect hemorheological disorders

The book examines various rheological aspects of the different etiology  stress. Hemorrhagic shock occurring at blood loss appears to be a powerful stress for the organism. The origin (emergence) and spread of stress reactions are characterized by the features of the macro-and microcirculation. In stressful situations the crisis of blood circulation affects the functions of hemorheological disorders, as well as appears to be a consequence of the shock. We were the first to combine these two problems.  

There is a maximum possible rate of adaptive energy consumption and at this maximum the organism cannot cope with any additional stimulus. At the same time adaptive and stress diseases develop. Let’s consider the duration and manifestation of Raynaud's disease from the perspective of adaptation diseases and diseases of the third grade, which appears to be the cause of the double stress effect — cold and emotional- physical and psychic.

Sleep apnea is a independent pathology and a powerful stress for the organism. Apnea is a cause of stress and strengthens the body under stress. We propose a new marker for apnea: platelet composes.

Our data in this book have practical significance for biomedicine.
