title: [State of intracellular signaling systems in endothelial dysfunction].
abstract: To estimate the state of different parts of intracellular signaling system associated with NO production after a2-adrenoreceptors stimulation under endothelial dysfunction in 22 patients with diabetic foot, the inhibitory analysis of clophelin-induced platelets aggregation modulation by administration of eNOS stimulator (L-arginin) and inhibitor (L-NAME), modulator of Ca-calmoduline (triphtazine), guanilate cyclase stimulator (sodium nitroprusside), inhibitors of phosphodiesterases (theophillinum) and protein kinase A (butamide). It was shown that endothelial dysfunction in patients with diabetic foot is associated with alteration of adrenoreactivity and inhibition of eNOS, guanilate cyclase, protein kinase A and stimulation of phosphodiesterases activity.
