Activity of kallikrein-kinin system of blood and state of placental circulation at full-term pregnancy

Abstract

The activity of kallikrein-kinin system of blood and the state of placental circulation at full-term physiological pregnancy have been studied.In 30 pregnant women aged 18—27 at 38th—40th weeks of pregnancy, the activity of kallikrein-kinin system (KKS) of blood before and after the action double local hypoxia of arm and the state of placental hemodynamics were analyzed. Three types of reaction of kininogenase and inhibitory chains of KSS were revealed: adaptive, kininogenase, and inhibitory. Disturbed placental hemodynamics was observed in pregnant women with kininogenase and inhibitory types of KSS reaction.
