The renal corpuscle of hibernating and non-hibernating Testudo graeca was studied by means of light and electron microscopy. Renal corpuscles are small and have a glomerular architecture similar to that found in other vertebrates with a limited glomerular filtration rate. In hibernating animals, unlike non-hibernating, some morphological changes took place. The cells of the renal corpuscle were densely packed, podocytes and parietal cells showed a marked cytoplasmic vacuolization, there was a highly developed capillary basement membrane and the endothelial and mesangial cells showed abundant dense granules. These morphological features apparently correspond to a vacuolar degeneration. They may also be the morphological basis of the decrease in the glomerular filtration rate observed during this period.
采用光学显微镜和电子显微镜对冬眠和非冬眠希腊陆龟的肾小体进行了研究。肾小体较小，具有与其他肾小球滤过率有限的脊椎动物相似的肾小球结构。与非冬眠动物不同，冬眠动物发生了一些形态学变化。肾小体细胞紧密排列，足细胞和壁层细胞出现明显的细胞质空泡化，有高度发达的毛细血管基底膜，内皮细胞和系膜细胞显示有丰富的致密颗粒。这些形态学特征显然对应于空泡变性。它们也可能是在此期间观察到的肾小球滤过率降低的形态学基础。
