title: [The stereological study on normal and intrauterine growth retardation (IUGR) placentas].
abstract: The stereological study was carried out in 8 normal and 22 IUGR placentas through Image Analysis System of Cambridge Instruments Quantimet 970 and 10 indices were analysed. The results showed that in the IUGR group the placental indices of total surface area of acroteric villus, total volume of intervillous space, volume density of fetal capillaries, total volume of fetal capillaries and surface area density of vasculo-syncytial membrane were significantly reduced than those in the normal group. The vasculo-syncytial membrane became significantly thick in the IUGR placental group. It was confirmed that a close relation exists between IUGR and placental quantitative changes. The major pathological findings of the placenta were prematuration and hypoplasia.
