Abstract
|
|
|
|
Rat liver sinusoids were observed by scanning electron microscopy. The sinusoids were provided with fenestrations which were divided into three types; small, medium-sized and large. The small fenestrations were usually gathered into clusters. The medium-sized fenestrations were either individually organized or in the cluster of small fenestrations. The large fenestrations were usually accompanied by small or medium-sized fenestrations. The lobule was divided into three zones; peripheral, intermediate and central, according to the distribution pattern of the fenestrations. The sinusoid providing with small fenestrations (type I) were predominant in the peripheral zone. The sinusoid showing medium-sized fenestrations (type II) were frequently observed in the central zone. The sinusoid having large fenestrations (type III) were abundant in the intermediate zone. This evidence indicate that the sinusoidal fenestrations become larger toward the intermediate zone from the peripheral zone of the lobule and progressively smaller toward the central zone. However, the fenestrations observed in the central zone seem to be larger than those seen in the peripheral zone of the lobule.
