Longitudinal changes in plasma glucose values of the 75-g glucose tolerance test in triplet pregnancies.

We evaluated longitudinal changing patterns of 75 g glucose tolerance test (GTT) in triplet pregnancies. Eight triplet pregnancies were prospectively studied. All triplet pregnancies were fertilized with artificial reproductive techniques; patients showed no glucosuria or fasting hyperglycemia > 100 mg/dL before pregnancy.

Cerebral blood flow distribution and hypoxic-ischemic brain damage in newborn rats.

Objective: Our purpose was to assess the cerebral blood flow distribution and resulting grade of hypoxicischemic brain damage in newborn rats.

Methods: Seven-day-old Wistar rats (n = 75) underwent left common carotid artery ligation followed by 2 hours hypoxia (8% oxygen in nitrogen) at 33 degrees C. The control animals were exposed to hypoxia without ligation (n = 8).
