ABSTRACT
The time-course of rapid changes in blood phosphoinositide content was studied in 48 patients with Stage II chronic alcoholism of and in healthy volunteers. Content of phosphoinositides was estimated within short intervals 30, 60, 120 and 180 sec after the samples were obtained. In the blood of the patients with alcoholism as compared with healthy volunteers the time-course of rapid changes in phosphoinositide content exhibited a higher amplitude and failed to return to the initial level within 3 min. Alterations in content of the phospholipid correlated with duration of alcohol abuse. The data obtained suggest that homeostasis of main biochemical regulators is impaired after alcohol consumption.

A total of 42 patients who had been abusing alcoholic beverages during different periods and 12 healthy individuals were examined. Their intracardiac hemodynamic parameters were evaluated by echocardiography and rapid changes in inositol-containing blood lipids were determined by thin-layer flow chromatography. The patients showed significantly reduced contractility of the left ventricle, its wall hypertrophy and greater cavity dimensions. These abnormalities were more pronounced in patients with an over 10-year history. Biochemical studies revealed a time course of rapid changes in inositol-containing lipids in patients, which showed more fluctuations in the content of phosphoinositides and their lower baseline and final levels and differed from that in healthy persons. It was stressed that the changes in inositol-containing lipids were also related to the duration of alcohol abuse and they reflected the mechanisms of the toxic action of ethanol on the myocardium, which might be useful in the assessment of the severity of cardiovascular events in alcoholism.
