摘要 冬眠前和出眠初期的中华大蟾蜍肝细胞的超微结构有如下特点 :(1)冬眠前肝细胞堆积有大量糖元颗粒 ,而出眠初期几乎无糖元颗粒 ;(2 )冬眠前肝细胞的粗面内质网非常发达 ,而出眠初期的粗面内质网不发达 ,常呈零散膨大 ;(3)线粒体的数量 ,细胞核和胆小管的形态结构在这两个时期无明显差异 ;(4)冬眠前肝细胞可分为两种不同的类型 The ultrastructure of the hepatocyte inBufo bufo gargarizans Cantor between pro hibernation and initial post hibernation was studied in this paper.The results show that:1.The hepatocytes in pro hibernation period have very plenty of glycogen granules,but nearly not glycogen granules in post hibernation period;2.The hepatocytes in pro hibernation period have very developed rough endoplasmic reticulum,but a few scattered dilatant rough endoplasmic reticula in post hibernation period;3.The quantity of mitochondria,and the structure of nuclei and bile canaliculi in pro hibernation period have not obvious difference from that in post hibernation period;4.Two types of hepatocytes in pro hibernation were found.The significance of the results mentioned above is also discussed.
