Abstract
A computer-assisted image quantiser has been used to provide a means of measuring cross-sectional areas of placental peripheral villi. A standardising technique was developed to adapt the instrument for this purpose. Application of this technique has demonstrated that the average reduction of peripheral villous mass in placentas from a malnourished Central American population, as demonstrated by other techniques, results from a reduction in the number of villi rather than in the dimensions of the existing villi.
Sommaire
On a fait usage d'un quantiseur d'image assisté par ordinateur, pour produire un moyen de mesurer les surfaces de section transversales du villus chorionique placental. Une technique d'étalonnage a démontré que la réduction moyenne de la masse chorionique villeuse dans les placentas de la population sous-alimentée d'Amérique Centrale, tel qu'il a été démontré par d'autres techniques, découle d'une réduction du nombre des villus plutôt que des dimensions des villus actuels.
Zusammenfassung
Ein Computer-gesteuerter Bildumwandler wurde verwendet, um ein Mittel für das Abmessen der Querschnittsflächen von plazentaren Chorionzotten zu besorgen. Eine standardisierende Technik hat bewiesen, daß die durchschnittliche Abnahme der chorionzottigen Masse in Plazenta von einer unterernährten Zentral-Amerikanischen Bevölkerung, wie durch andere Techniken dargestellt wurde, seinen Ursprung vielmehr in der Zahl der Zotten als in den Dimensionen existierenden Zotten hat.
