Résumé L étude morphométrique des capillaires rétiniens de souris à piquants de différents âges (3, 6, 12 et 36 mois) a démontré un épaississement des membranes basales et un élargissement des diamètres capillaires en fonction de l'âge et, en outre, l'existence d'une corrélation positive entre ces deux paramètres.
Abstract:
zusammenfassung Die morphometrische Untersuchung von Retinakapillaren verschieden Alter (3, 6, 12 und 36 Monate) Stachelmäuse (Acomys cahirinus) ergab eine altersabhängige Zunahme sowohl der Basalmembrandicke als auch des Kapillardurchmessers. Zudem wurde eine positive Korrelation zwischen diesen beiden Parametern gefunden.
Notes:
Abstract Specimens of four age groups of non-diabetic, non-obese spiny mice (Acomys Cahirinus), 3, 6, 12, 36 months old respectively, were examined for changes in retinal capillaries. Morphometrical evaluation of electron-micrographs allowed to conclude that capillary basement membrane width, as well as capillary diameter, increase during ageing: the values in the four different age groups were found to be 656, 925, 1098, 1772 Ångström units for the average basement membrane width, and 3,72, 4,08, 4,58, 5,60 microns for average capillary diameter. The differences between the age groups proved to be significant at a p 〈 0,01. Furthermore, a positive correlation between capillary diameter and capillary basement membrane width seems to be highly probable.
