title: [Bacterial lipopolysaccharides: comparative analysis of the cardiovascular effects of E. coli, S. sonnei and Y. enterocolitica in anesthetized rats].
abstract: Intravenous injection of S. sonnei LPS (640 mcg/kg) and of Y. enterocolitica LPS (1280 mcg/kg) elicited a decrease in mean arterial pressure and heart rate in urethane anaesthetized rats. The bradycardia reached a maximum when hypotension had already reverted, thus suggesting direct and independent effects on the vessels and on the heart.
