Does prolonged cyclic strain impair the fibrinolytic system in cultured vascular endothelial cells?
Prolonged tensile stimulation impairs fibrinolytic activity in human aortic endothelial cells by a dual action, with suppression of plasminogen activator expression and increased inhibitor production. This effect of tensile stress may contribute to the reduced fibrinolytic capacity observed in patients with hypertension.
The prophylactic administration of more than 1 antibiotic for more than 24 hours following severe trauma does not offer additional protection against sepsis, organ failure, and death, but increases the probability of antibiotic-resistant infections.
