用透射电镜(TEM)观察了喂高脂饲料兔肝贮脂细胞的超微结构并讨论了其功能。伴随喂高脂饲料的时间增长贮脂细胞有以下变化:贮脂细胞的数量增加,体积明显增大;核内异染色质减少,常染色质增多;吞饮现象增强,糖原颗粒增多;脂滴大量增加,其周围有糖原颗粒包围,或有糖原颗粒团块相贴。认为喂高脂饲料后,贮脂细胞功能增强;推测贮脂细胞对机体有强的保护作用。讨论了脂滴形成过程:还证实了贮脂细胞具有合成胶原原纤维及参与肝纤维变性的作用。
Transmission electron microscopy (TEM) was used to observe the ultrastructure of hepatic fat-storing cells fed high-fat diet and its function was discussed. With the increase of time for feeding high-fat diets, the fat-storing cells have the following changes: the number of fat-storing cells increases, the volume increases significantly; the heterochromatin in the nucleus decreases, the euchromatin increases, the engorgement phenomenon increases, and the glycogen granules increase; A large increase in droplets, surrounded by glycogen granules around, or glycogen granule mass paste. It is believed that the function of fat-storing cells is enhanced after high-fat diets are fed; it is speculated that fat-storing cells have a strong protective effect on the body. The lipid droplet formation process was discussed: It was also confirmed that the lipid-storing cells have the ability to synthesize collagen fibrils and participate in hepatic fibrosis.
