Influence of chronic alcoholic intoxication and lighting regime on karyometric and ploidometric parameters of hepatocytes of rats

The features of the diurnal dynamics of the area of rat hepatocyte nuclei and their ploidy were studied under conditions of a standart (fixed) light regime and constant illumination, as well as under chronic exposure to alcohol in the mentioned light regimes. It has been shown that exposure to alcohol and exposure to constant illumination separately lead to a change in the amplitude-phase characteristics of the circadian rhythm of the nucleus area, while the combined effect of these factors leads to a complete destruction of the rhythm, which indicates a violation of adaptation processes. An increase in the average ploidy of hepatocyte nuclei in chronic alcohol intoxication is also shown, while in animals kept under constant illumination without drinking alcohol, the values of this parameter decrease, which indicates a successful course of the adaptation process. The conducted research indicates that the results of karyometric and ploidometric analysis characterize the degree of influence of alcohol intoxication and changes in the light regime on the liver of rats, reflecting the rate of efficiency of adaptation to these factors.

Changes of the intestinal microbiota during chronic alcohol intake

This paper examines the influence of chronic alcoholic intoxication on the qualitative and quantitative composition of the intestinal microbiota in patients with syndrome of alcohol dependence. The authors describe chronic alcoholic intoxication, accompanied by significant violations of homeostasis, which is manifested by changes in protein, carbohydrate, lipid, and mineral metabolism. The authors examine the role of alcohol as one of the main factors that affect dysbiotic shifts in the normal microbiota of human intestines. The paper presents the results of the comparison found earlier in the course of experimental work, significant changes of the intestinal microbiota of rats subjected to chronic alcoholism and clinical results of the study of the microbial landscape in patients with syndrome of alcohol dependence. The authors established that under the influence of alcohol there is a statistically significant reduction in saccharolytic microbiota. The obtained data are a part of a clinic-experimental study of changes in the state of resistance of the organism exposed to the chronic effects of alcohol and can serve as a basis for further study of the intestinal microbiota changes, which is an important component of a personalized approach to the definition of tactics of treatment and rehabilitation of people with the syndrome of alcohol dependence.
