[Behaviour of human placental lactogen (HPL) following continuous glucose infusion in late pregnancy (author's transl)].

Continuous intravenous glucose infusion was applied to 15 pregnant women of normal body weight, in the 37th week of pregnancy. The glucose levels in the blood, serum immunoreactive insulin, and placental lactogenic hormone (HPL) were monitored for three hours. Glucose tolerances were found to be normal in five probands, borderline in another five, and pathological in five, as well. No relationships were found to exist between insulin requirement und plasma HPL levels. While all HPL levels were somewhat increased in those patients with pathological glucose tolerances, the differences were not significant.
