Environmental influence of polycyclic aromatic hydrocarbons observed not only on the general state of the organism, but also the influence on the nervous system in particular. Also consider compensation mechanisms when exposed to polycyclic aromatic hydrocarbons. Anabolic agents through restorative and bio-stimulating effect, can have a beneficial effect in the treatment of almost any disease, and therefore the range of medical indications for the use of anabolic steroids is constantly expanding. https://www.biotech-asia.org/vol14no1/morphological-characteristics-of-experimental-encephalopathy-under-influence-of-toxic-polycyclic-aromatic-hydrocarbons-with-their-correction/ Ecdyphyt morphological characteristics of brain hemisphere sections; Hematoxylin and Eosin stain (H & E) the impact of polycyclic aromatic hydrocarbons;  morphological and functional changes in the brain tissue;
