[Evaluation of the actiom of lipoic acid in ischemia and hypertension].

A total of 203 patients, 48 -- with ischemic and 155 -- with hypertensive disease in the 11A and 11B stages, were examined. The effect of lipoic acid (LA) was assessed on the ground of the dynamics in the clinical picture of the patients, some vitamins allowance figures and the activity of a number of enzymes in leucocytes, erythrocytes and in the blood serum. The LA was administered in the form of tablets, in a dose of 75 mg per day, for 10 dyas. As controls served 90 patients with ischemic and hypertensive diseases. Investigations showed the LA to have but a little influence on the clinical picture of the disease, raising somewhat the beta-lipoproteids level in patients with hypertensive and ischemic disease, irrespective of their age, and increasing the level of free fatty acids in patients over 50, forcing it down in those below 50. An age-specific effect of the LA on the blood proteinic spectrum was disclosed, viz. in patients below 55 it increased the proportion of albumins and reduced that of gamma-globulins, whereas in those aged above 55 reverse picture was in evidence. In the young LA had the tendency of bringing down the coagulating activity of the blood; whereas disaggregation of thrombocytes changed not depending upon the age, but on the form of the affection, decreasing in patients with hypertensive disease and remaining unchanged in those with ischemic heart disease. The LA helped normalize the thiamine metabolism in the organism and that of the thiamine-diphosphate containing enzymes with concurrently disturbed utilization of riboflavin in the examined patients.
