In the blood serum, the concentration of tumor necrosis factor (TNF-a), interleukin (IL-2), (IL-6), (IL-10) was determined by the enzyme immunoassay. Histostereometrically, at the testes micronutrients, nuclear-cytoplasmic relation in vascular endothelial cells, spermatogenic epitheliocytes, as well as relative volumes of da­maged endothelial cells, spermatogenic epitheliocytes, and stromal-parenchymatous relation in organs were determined. Correlation analysis was performed between cytokine concentrations and histostereometric parameters studied to determine the correlation coefficient (r). Quantitative indicators were processed statistically.</p><p><strong>Results and Discussion.</strong> It was found that when exposed to rubomycin hydrochloride on the body, the concentration of IL-2 in the serum increased by 22.0 %, IL-6 – by 45.2&nbsp;%, IL-10 – by 34.5 %, TNF-α – by 12.5 % ​​(p&lt;0.001). The uneven, disproportionate increase in cytokines content in the serum in simulated pathology indicated an imba­lance of the cytokine profile. Nuclear-cytoplasmic relations in vascular endothelial cells increased by 5.3 %, in spermatogenic epitheliocytes – by 7.4 % (p &lt;0.01), which indicated a violation of structural cellular homeostasis. The relative volume of damaged endothelial cells increased by 13.5 times, and the spermatogenic epitheliocytes&nbsp;– 19.4 times (p&lt;0.001), which indicated significant structural and functional changes of this organ. The pre­sence of strong positive correlation relations between the relative volumes of damaged endothelial cells, spermatogenic epitheliocytes and concentrations of IL-2, IL-6, IL-10 (r=+0.82±0.03). The smaller correlation between the indicated histostereometric parameters of the testes and the serum TNF-a concentration (r=+0.65±0.02) were found to be less positive. Between the stromal-parenchymal relations in the testes of the 2<sup>nd</sup> group of observations and the content of cytokines in the serum, the correlation coefficient ranged from 0.52 to 0.64.</p><p><strong>Conclusions.</strong> The introduction of rubomycin hydrochloride into the body results in pronounced damage to the testes and a significant imbalance of the cytokines IL-2, IL-6, IL-10, TNF-a in the serum. The degree of impaired cytokine profile in modeled pathology correlates with the severity of changes in structural homeostasis, relative volumes of damaged endothelial cells, spermatogenic epitheliocytes, stromal-parenchymal relations in the investigated organ.</p> ER -
