title: [Changes in the content of beta-endorphin in maternal and fetal blood during transcutaneous electric neurostimulation in premature labor].
abstract: The effect of various parameters of transcutaneous electrical neurostimulation (TENS) on changes in B-endorphin (BE) blood plasma level has been studied in the mother and fetus during premature labour. A dependence of changes in BE plasma level on the frequency regimen of the impulse current has been established. The data, on the one hand, demonstrate the regulating effect of high- and low- frequency TENS on BE blood level and, on the other hand, indicate the involvement of endogenous opioid fetus system, which enables it to endure labour-induced stress.
