ageing

The purpose of the study was an assessment of erythrocyte system age-dependent characteristics in elderly population dwelling in the same territory during the time period equal to the average life span in the region. Material and Methods. We perform the compare of hematological parameters of 800 patients with hypertension and coronary heart disease hospitalized during 25-years period. Results. In senile patients, red blood cells and hemoglobin levels signifi- cantly decrease, but platelet characteristics remain intact. Revealed differenced are similar during all 25-year period of observation. Conclusion. Over the past 25 years, the trend of age-related decline in the number of red blood cells and hemoglobin has been preserved. The average hemoglobin content in erythrocyte (MCH) during the aging process tends to decrease, which has become statistically significant in recent years. The principal difference of the obtained data from the results of obtained 25 years ago is the absence of an age-related increase in the volume of erythrocytes and a higher level of the average concentration of hemoglobin in the erythrocyte.

Age-related diseases and their link to involutionary processes in human organism remain as one of the burning problems in internal medicine. The article focuses on the discussable questions of the most common mechanisms of atherogenesis and ageing, their similarity and difference. Both processes mutually burdens each other, bringing the "fading" of the organism closer.

The given work summarizes external data and self-obtained results on development and diagnostic of kidney involution modifications. Article discusses definition of "senile kidney" as a clinical and pathomorphological term. Major statements on pathophysiological causes of age-associated renal disorders and their prognosis, specifics of chronic kidney disease in elderly and senile patients have been reviewed. Phenomenon of renal "multimorbidity" in eldely maximizes worsening risk of unmodifiable kidney function.

The purpose of the study: to examine age-dependent dynamics of parameters of biochemical screening in long-livers. Material and methods. The study included 201 long-livers divided (Saratov) into two groups: the main group (centenarians) and the control group (90-99 y.o.). Basic parameters of biochemical screening were analyzed. Results. The suited sample of centenarians characterized by significantly lower levels of total cholesterol, triglycerids, glucose and creatinine. All studied parameters progrediently decreased from early long-livers age to centenarians. Maximal rates of age dependencies allowed us to confirm maximal weight of lipids in early longevity and glucose and creatinine in centenarians. Conclusion. All present results are most likely explained by the combined effects of genetic, environmental and "hundred years" factors leading to dynamic remodeling of control systems. Major result of such remodeling is age-dependent optimal level of metabolic factors as a mechanism of successive ageing.

Present article summarizes the results of long-term studies of cardiovascular health parameters in war veterans of Saratov region admitted to Saratov regional hospital for war veterans. Cardiovascular disease spectrum and its prevalence dynamics were studied in war veterans. Clinical signs and disease course features of cardiovascular pathology were systematized including Great Patriotic War veterans, who successfully had reached the state of longevity.

The article summarizes the results of healthcare management of Great Patriotic War veterans for the last 20 years. This period included approbation and improvement of high-technology science-based and efficient healthcare system for war veterans. Healthcare managerial, medical and diagnostical activities are based on original analytical development including population system approach, biophysical approach to human organism, ageing, and senile and stress-induced disorders.

The results of complete clinical and demographic investigation of Volga Region population of long-livers have been presented. Anthropologic, social, clinical, laboratory and instrumental markers of longevity have been determined.

Purpose: to study the morphological characteristic of a coronary blood flow and feature of erythronJs system at ischemic heart disease in aged patients. Methods. Morphological and functional characteristics of coronary blood flow (according to the data of selective direct angiocoronarography) and also cytomorphological and functional parameters of peripheral blood flow in aged patients with ischemic heart disease have been used. Results. Statistically reliable differences to parameters of «red» blood are determined. Lowering of erythrocytes has been established in women. The parameters of haemoglobin level, hematocrit and increasing of erythrocyte sedimentation rate was marked in both gender. The gender distinctions of age have been revealed remodeling of coronary arteries. Conclusion. The high probability of erythronJs system participation has been shown namely its peripheral link in process of age remodeling of coronary arteries in aged men with ischemic heart disease

Aim: to estimate the dynamic regulation of cerebral blood flow (CBF) and significance of clinical, and laboratory parameters as a possible markers of CBF violations. Material. 179 elderly patients with arterial hypertension were involved in the study. Transcranial Doppler ultrasonography (Philips Envisor HD, USA) was used for CBF parameters dynamics during orthostatic hypotension. Results. Main directions of CBF parameters changings (Friedman ANOVA p 0,0091 ... 0,012, coeff. of concordance 0,308 ... 0,691) were detected. Gender differences of CBF parameters, as well as blood pressure level influence upon CBF regulation during orthostatic hypertension were studied. Conclusion. Received data allow us to consider gender, controlled or uncontrolled hypertension, cytomorphological parameters of peripheral blood, diuretics usage as clinical, and laboratory markers of dynamic regulation of CBF in elderly patients with arterial hypertension

Aim: To estimate the dynamics of intima-media complex in elderly patients with arterial hypertension. Materials: 179 elderly patients with arterial hypertension were involved in the study. Mean intima-media wall thickness (IMT) of common carotid arteries in plaque-free sites and prevalence of plaques were evaluated by B-mode ultrasound investigation (Philips Envisor HD, USA). Results: IMT changing was of nonlinear character, remained stable up to 74 years. Mean rate of the following IMT augmentation was 0.157 mm per year. Frequency of atherosclerotic plaque revealing was significantly increased since the 7th decade. Significant correlation between IMT and systolic, diastolic, mean blood pressure levels or medication spectrum was not revealed. Conclusion: Received data proved significant influence of aging upon IMT enlargement
