Profile of the Plasma Catecholamines of Sexually Mature Rats Exposed to a Combination of Factors of Different Natures

AbstractChanges in the catecholamines concentration in plasma depend on the rhythm of the external light signal. Light desynchronosis has the strongest influence on the change in the dopamine concentration in the blood plasma. The combined effect of the physical factor, i.e., prolonged changes in the light regimen, and the chemical factor (single, acute poisoning with a neurotoxicant) results in the activation of exogenous and endogenous pathways for the regulation of the biological rhythms of catecholamine secretion into the blood plasma. The most pronounced changes were observed in blackout conditions.
