摘　　要：对荒漠沙蜥(Phrynocephalus przewalskii)冬眠前及冬眠中期的肝脏、胰腺和脂肪体的超微结构进行了比较观察。结果表明,荒漠沙蜥肝脏、胰腺和脂肪体中的糖原颗粒、脂滴、内质网、线粒体等细胞结构有明显变化。冬眠中期胰腺腺泡细胞线粒体中出现致密颗粒,核周间隙增宽,核中出现无定形体。文中对上述结果的生理意义进行了讨论。Comparative observations on the uhrastructure przewalskii during the pre-hibernation and mid-hibernation of the liver, pancreas and fat body in Phrynocephalus periods were conducted. The results showed that evident changes in the cellular structures including glycogen particles, lipid droplets, endoplasmic reticulum, mitochondria occurred in the liver, pancreas and fat body during the transition of these two periods. During the mid-hibernation period, dense granular bodies appearred in the mitochondria, the perinuclear space increased, and the amorphous bodies appearred in the nucleus of the pancreatic acinar cells. This paper discusses the physiological significance of the above-mentioned results.
