质膜内褶

本文对大鼠肝脏枯否细胞质膜内褶形成的结构做了电镜观察。

Rat liver with glutaraldehyde perfusion and immersion fixation is prepared to be investigated by an electronic microscope , Invaginations of Kupffer cell membrane are observed .

结论：糖网病大鼠视网膜色素上皮细胞的损害主要表现于微绒毛、质膜内褶及细胞器的损害，并无脉络膜与视网膜之间屏障功能的损害。

Conclusion : The damage were mainly in the microvilli of plasmic membrane of basis of retina pigment epithelium in DR rats , but there were no damage to the choroid membrane retina barrier .

它的近曲小管和收集管上皮细胞无质膜内褶，远曲小管上皮细胞有较少的质膜内褶。

The plasma membrane infoldings were absent in the epithelial cells of its proximal renal tubule and collecting tubule , and were present but fewer in the epithelial cells of its distal renal tubule .

肾小管上皮细胞局灶性胞质溶解，微绒毛紊乱或脱落，线粒体出现浓聚或肿胀现象；细胞核不同程度固缩；质膜内褶出现不同程度的水肿现象。

Local cytoplasm dissolution was appeared in renal tubular epithelial cell , microvilli was disordered or got lost , edema or aggregation occured with mitochondrial ; the phenomenon of nuclear pyknosis was found in varying degrees ; the infolding of the plasma membrane occurred different degrees of edema . 2 .
