Nitrogen Oxide, Endothelin-1, and Serotonin in the Blood of Immature Spontaneously Hypertensive Rats

Аннотация

Endothelial function is an early and sensitive marker of subclinical increase of BP in children and adolescents. It is associated with an imbalance of the key vasoactive factors (NO, endothelin-1, and serotonin). Immature spontaneously hypertensive rats (SHR line) are characterized by increased plasma concentrations of NO and endothelin-1 (by 14.7% and 2.9 times, respectively) and increased serotonin content in the plasma and platelets (by 2.7 and 2.3 times, respectively) in comparison with Wistar-Kyoto rats. Platelet count in the blood of SHR rats is by 50% higher than in Wistar-Kyoto rats.
