EFFECTS OF TRANSCRANIAL ELECTRICAL THERAPY ON SYSTEMIC INFLAMMATION IN A HIGH-FAT FRUCTOSE DIET

The study aims to conduct a transcranial electrical stimulation therapy trial in rats influencing the indicators of systemic inflammation dynamics and the percentage content of visceral adipose tissue in a highfat fructose diet. The study included 180 male outbred rats, which were randomly distributed into three groups: the first group had a standard diet; the second group received the high-fat fructose diet; and the third group received both transcranial electrical stimulation therapy and the high-fat fructose diet. Tumor necrosis factor-α, interleukin-15, and interleukin-19 concentrations were measured in blood serum. The percentage of visceral adipose tissue in relation to body weight was calculated. The percentage content of visceral adipose tissue and serum concentration of tumor necrosis factor-α were lower, and interleukin-19 was higher in rats that received transcranial electrical stimulation with a high-fat fructose diet in comparison to the second group, which did not undergo the stimulation. Interleukin-19 level in the blood serum of rats in the second group grew as the trial progressed, whereas the opposite occurred in the third group. There was an inverse relation between the predictive variables of transcranial electrical stimulation, interleukin-19, and the variable of tumor necrosis factor-α. The data obtained in the experiment may also indicate that interleukin-15 cannot be unequivocally considered as a key factor associated with a decrease in visceral adipose tissue content when introducing a high fructose and animal-based
saturated fat diet to rats.
