Background. Transcranial electrical stimulation is a promising method for correction of malnutrition-induced hyperlipidemia, in the absence of indications for drug hypolipidemic therapy in young and middle-aged patients with low and moderate cardiovascular risk. Objectives — to study the effect of transcranial electrical stimulation on lipid metabolism in a high-fructose/high-fat (HFHF) diet in rats.Methods. An experimental randomized trial was performed to study the effect of transcranial electrical stimulation on lipid metabolism in a high-calorie diet enriched with fructose and saturated animal fat in rats. The experiments involved 180 outbred male rats and were carried out on the basis of the vivarium of Kuban State Medical University. The animals were divided into three groups: group 1 (control group, n = 60) — followed a standard diet; group 2 (comparison group, n = 60) — followed a HFHF diet; group 3 (experimental group, n = 60) — underwent transcranial electrical stimulation against the background of a HFHF diet. According to the target reference point of the study, the groups were divided into three equal subgroups of 20 rats each: subgroup A — day 30, subgroup B — day 60, and subgroup C — day 90 (biomaterial sampling and euthanasia were carried out on those days). In the obtained blood samples, the following lipid metabolism parameters were evaluated: total cholesterol, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and atherogenic index. Statistical analysis was performed using Microsoft Office Excel 2021 (Microsoft, USA), GraphPadPrism 9 (GraphPad Software, USA) and Statistica 13.3 (StatSoft, USA).Results. On the 30th day of the study, it was noted that in group 3, the concentration of low-density lipoprotein cholesterol was 14.9% lower and the atherogenic index was 30.8% lower (p < 0.05) than in group 2, while total cholesterol concentration, triglycerides, and high-density lipoprotein cholesterol had no statistically significant differences (p > 0.05). On the 60th day of the study, in group 3, when compared to group 2, the concentration of total cholesterol was 18.7% lower, low-density lipoprotein cholesterol was 42.9% lower, high-density lipoprotein cholesterol was 16.7% higher, and the atherogenic index was 56.3% lower (p < 0.05), while triglycerides had no statistically significant differences (p > 0.05). On the 90th day of the study, in group 3, when compared to group 2, the concentration of total cholesterol was 29.2% lower, the concentration of triglycerides was 36.0% lower, low-density lipoprotein cholesterol was 42.8% lower, and the atherogenic index was 57.0% lower (p < 0.05), while the concentration of high-density lipoprotein cholesterol had no statistically significant differences (p > 0.05).Conclusion. High-fructose/high-fat diet leads to a progressive increase in the serum concentration of low-density lipoprotein cholesterol, total cholesterol, triglycerides, as well as to a moderate decrease in high-density lipoprotein cholesterol and a growth in the atherogenic index. Transcranial electrical stimulation has a moderate lipid-lowering effect, manifested in the form of a decrease in the serum concentration of low-density lipoprotein cholesterol, total cholesterol and atherogenic index, while the effect on the concentration of triglycerides and high-density lipoprotein cholesterol is insignificant.
