Abstract
The results of rheoencephalography of female smokers 17–21 years old and control group were studied and analyzed. The aim of this work was to explain and analyze physiological features of smoking effect on functional changes of regional hemodynamics in smoking women. The study of cerebral hemodynamics was carried out by the method of rheoencephalography (REG) – automated system of complex examination “Askold”, intended for automation of medical tasks processing with input of information in “online” regime (insertion of data directly from examined person). The recording of rheogram was carried out in front-mastoid branches that allowed register REG separately in both hemispheres of brain and determine the main amplitude-temporal characteristics of cerebral blood circulation and changes of vascular tone. Analyzing the main indices of regional hemodynamics in female smokers, the statistically lower values of time of rheowave delay (Ra) were noted. There was also revealed a decrease of volumetric cerebral blood circulation and increase of resistant arteries tone. There were fixed the moderate asymmetry (from 15 to 25 %) of blood filling in vertebral-basilar vascular basin (basin of spinal and internal carotid arteries) and the signs of complicated venous outflow in both hemispheres. Such changes of indices indicate the decrease of volumetric blood circulation of cerebral hemodynamics, striking volume of blood and increase of tone of distribution arteries that testify to the decrease of blood circulation in main vessels, and also smoking is a cause of hypoxia (oxygen deprivation) of cerebral cells as a result of decrease of blood inflow. In the women of control group all indices are within norm that testifies to the normal course of physiological processes in organism.
Highlights
The one of most important problem of the modern society is the increase of people with different types of addictions, and the most spread of them is smoking
The analysis of rheoencephalorgaphy results demonstrated that the deviations of such indices from the norm were often observed in examined women (Table 1)
The results of rheoencephalograpgy revealed that women-smokers are characterized with statistically lower values of time of rheowave delay (Ra) at р
Summary
The one of most important problem of the modern society is the increase of people with different types of addictions, and the most spread of them is smoking. The smoking and its medical-demographic and economic results are the subject of scientific interests of many native and foreign scientists [1,2,3]. In most countries of the world the phenomenon of smoking and the prevalence of diseases and deaths, caused by tobacco consumption are considered as an important medical, social and economic problem [5]. For today Ukraine belongs to the countries with high prevalence of smoking among men, and women. Today near 20 % of women of working age smoke in our country [6]
