Upper portions of the thoracic aorta annexing to the aortic arch were used for the study of the fenestration distributions on the elastic lamellae of the media. Specimens were of adult SD rats and of WKYs. Distributions of the fenestration were calculated on 4 μm-thick microscopic preparations at 10μm-bin intervals. Changes of the fenestration count along the longitudinal axis of the aorta showed rough cyclic fluctuations at an interval of 30-40μm. Autocorrelation coefficient changes at the upper, the middle and the lower portions of the thoracic aorta as far as 2 cm apart from the aortic arch showed similar tendency with the positive correlation at roughly 30-40μm distance. The results obtained on SDs and WKYs showed similar changes on the fenestration distributions. This would indicate the common unit structure of the elastic lamella in the rat. Thus it is deduced that the common size of the lamella is 30-40×30-40μm, with fairly large variations due to the loose regular orientation.
