Abstract

Using morphometric technique, the present study was made of the kidney of rabbit embryo in the 13 days of the gestation. Their section areas of the renal tubules and the glomerular cells were compared with the those of adult rabbit, 1. In the developing renal tubule, the tubular section areas were larger than that of the adult, but the nuclear section areas of tubular calls were smaller than the adult. The microvilli of their cell surface were poorly developed, and their cytoplasm contained well developed mitochondria with euchromatic nucleus. 2. In the developing glomeruli. the nuclear section area of the cells of the parietal layer, the podocytes, and the endothelial cells were similar size, but their nuclei were larger than those of the adult. The cytopalsm of the podocytes contained well-developed rough endoplasmic reticulum, Golgi apparatus, and round mitochondria.

태생 13일된 토끼의 발생기 신장에서 뇨세관과 사구체 세포들의 크기와 형태를 관찰하여 성숙한 토끼의 신장과 형태계측학적으로 비교한 결과 다음과 같은 결과를 얻었다. 1. 태생 13일의 발생기 뇨세관 단면적은 성숙한 토끼의 근위세관 단면적보다 훨씬 넓고 평균직격이 길었으며 내강이 거의 없었다. 뇨세관 상피세포의 솔모양 가장자리는 발달되지 않았고 핵 위쪽에 둥근 사립체가 발달되었으며 기저막부분에는 사립체가 적었다. 2. 발생기 사구체내에는 벽측세포, 족세포, 내피세포들로 구별되었으며 성숙한 토끼보다 내피세포와 벽측세포의 세포핵 단멱적이 훨씬 컸고 성숙한 토끼의 사구체에서는 족세포가 가장 컸으나 발생기에는 내피세포의 크기가 가장 컸다.
