title: [The effect of agonists and antagonists of opiate receptors on the activity of the kallikrein-kinin system in hemorrhagic shock].
abstract: Mean blood pressure and heart rate have been registered in the experiments on male Wistar rats. Kallikrein-kinin system (KKS) components have been evaluated in blood plasma: plasma kallikreinogen, kallikrein-inhibiting capacity, spontaneous esterase activity. The parameters were determined before and after hemorrhage in the volume accounting for 10, 20 and 30% of the circulating blood volume. The rats were administered enkephalin analogues--DAGO, DADL and naloxone. The administration of mu-agonist DAGO improved hemodynamics. DAGO effect was eliminated by naloxone. The administration of enkephalins did not affect KKS parameters, while naloxone potentiated KKS changes induced by hemorrhage. It has been shown that KKS is not involved into the mechanism of hemodynamic changes in response to enkephalin administration during hemorrhagic shock.
