Abstract—We studied the effects of a derivative of indole morphine (Trisan) during induction of labor on the
activity of enzymes of antioxidant defense in the brains of fetuses that developed under normal (intact) and dis-
turbed (experimental) placental blood circulation. We show that Trisan has antihypoxic and moderate antioxi-
dant characteristics and decreased intranatal oxidative stress in the CNS of intact and experimental fetuses.

Keywords: fetal hypoxia, brain, placental insufficiency, antioxidant system
