摘要
本文对冬眠前、冬眠和冬眠后期的刺猬（Ｈｅｄｇｅｈｏｇｓ）肾脏和肾上腺的超微结构进行了比较观察，发现冬眠期刺猬肾脏滤过膜的足细胞次级足突有融合趋势，裂孔少而狭小，毛细血管内皮细胞的窗孔较稀疏；肾上腺皮质束状带细胞的体积较小、胞浆中脂质含量较少而细小；肾上腺髓质细胞中所含的高电子密度分泌颗粒数量较少，为有关动物学研究提出了超微结构学依据。
We have made the ultrastructure observations on erinaceus curopaeuses' kidneys and adrenals before, during and after the period of hibernation. The results show that the podocyte secondary processes of the kidney glomerules were a merging tendency,the silt pores became fewer in number and narrowed. More red blood cells were found in lumen of blood capillaries and the number of window pores in its endothelial cells decreased. The fatty granules in adrenocortical zona fasciculata cells became smaller in size,and fewer in number. The numbers of the two kinds of secretion granules in adrenal medulla cells were reduced as compared with those in the other two periods.The observation above have provided an ultrastructural evidenee for various relevant zoological studies.
