Abstract:
We studied the effect of NO synthase inhibitor 2-amino-5,6-dihydro-4H-1,3-thiazine (2-ADT) on the cardiovascular system in rats with endotoxic shock. Blood pressure, heart rate, and respiratory rate were recorded. E. coli lipopolysaccharide decreased blood pressure and heart rate. 2-ADT in a dose of 5 mg/kg normalized these hemodynamic parameters. The normalizing effect of 2-ADT decreased with increasing the dose of this preparation. 2-ADT in high doses (10, 20, and 30 mg/kg) and repeated injections of the preparation caused death of experimental animals.
