ABSTRACT. Due to the high relevance of the problem of searching for early biomarkers of neurotrophic dysfunctions, the levels of the neurospecific protein VEGF and some of macro- and trace elements in the blood serum during ischemic brain pathology were studied in a clinical setting at the neurological department of Clinical Hospital No. 123 of the FMBA of Russia. The study included male patients (n = 51) diagnosed with ischemic stroke, mean age 65±0.3 years. The comparison group was represented by healthy male volunteers (n = 39), average age 62±0.6 years. Concentration of VEGF was determined by enzyme immunoassay, concentration of elements Mg, Mn, Cu, Se, Zn was determined by mass spectrometry with inductively coupled argon plasma (ICP-MS). It was found that in patients with cerebral pathology the level of VEGF was 4.7-fold higher than in the control group, the serum copper content exceeded the corresponding value of the control group 1.2-fold, the manganese content – 1.8-fold, the selenium and zinc content – 1.3-fold. The presence of significant correlations between the level of VEGF and all studied essential elements was also found. For copper, manganese, magnesium and selenium, the correlation was positive (R = 0.4–0.8; p <0.05), and for zinc it was negative (R = 0.8; p < 0.05). The results indicate the probable presence of multilevel mechanisms of ischemic stroke, presented at the molecular and biochemical levels, as well as the possibility of developing a strategy to optimize the reparative processes of ischemic nervous tissue by modulating metal ligand homeostasis.
