染色质

Daxx can be localized in promyleocytic leukaemia protein oncogenic domains, nucleoplasm. nucleolus, cytoplasm, and heterochromatin.

Daxx可定位于早幼粒细胞白血病蛋白核体、核质、核仁、胞浆和异染色质。

An early spermatid had a round nucleus with reticulate chromatins and there were many mitochondria and Golgi vacuoles in the cytoplasm.

早期精子细胞核圆，染色质呈网状分布，胞质中有许多线粒体和高尔基液泡。

It was observed that cellular contents, including chromatins and organelles,migrated in PMCs through cytoplasmic channels,mainly at the stage of synizesis in meiotic prophase Ⅰ.

观察发现，处于凝线期的花粉母细胞，其内含物，包括细胞器和染色质，主要通过胞质通道向相邻细胞发生转移。

Transmission electron microscopy examination: epithelium cells degeneration, chromatin margination and collagen arrangement disorder could be observed at early stage after bothsided LASIK.

透射电镜下：BSL术后早期上皮细胞轻微变性，少量纤维细胞核染色质边集，角膜瓣边缘局部胶原排列稍紊乱。1mo时基质胶原纤维排列整齐，直径大小一致。

By means of the transmission electron microscope we found the typical morphology variation of apoptosis,such as the concentration and side-accumulation of the nuclear chromatin,the fragmentation of the nuclear and the concentration of the cytochylema etc.Cell cycle detected by flow cytometry showed one visible apoptosis peak (20.6%) in front of the peak of G1.The typical ladder was found in the 15 g.L-1 agarose gel electrophoresis of the nucleus DNA.

透射电镜下可见细胞核染色质浓缩、边集、核碎裂及胞质浓缩等凋亡细胞典型的形态学改变；流式细胞术周期分析显示在G1期峰前存在一个凋亡峰（20.6％）；核琼脂糖凝胶（DNA 15 g.L-1）电泳呈梯状。

ResultsThe glandular cell in the endometrial implant after therapy with middle or high-dose of (10,15 gkg-1d-1) XiaoChaiHu Decoction showed characteristic features of apoptosis which displayed by the cell decreased in size, karyopyknosis , cytoplasmic and nuclear chromatin condensation , density increased and a lot of apoptotic bodies among cell. Whereas some stromal cell displayed degeneration and necrosis. The protein expression of Fas and Caspase-3 in endometriotic tissue of XiaoChaiHu Decoction group was higher than that in the endometrium.

结果中、高剂量小柴胡汤（10，15 gkg-1d-1）治疗后，异位内膜有较多腺上皮细胞出现凋亡的特征，表现为细胞体积变小，核固缩，胞浆和核染色质凝集，密度增高，细胞间凋亡小体，同时间质细胞中可见一些坏死细胞；异位内膜Fas蛋白、Caspase-3蛋白的表达水平明显高于其在位内膜。

Under electron microscope, tumor cell emerged karyopyknosis, new-moon shaped or circular, nucleus membrane was clesr, endoplasmic reticulum was dilated, and mitochondrion was swollen. A lot of apoptosis cells emerged in the tumor foci under light microscope.

光镜下显示肿瘤灶中出现许多凋亡细胞；肿瘤组织电镜观察，瘤细胞核染色质浓集成块，在核膜内呈新月形或环形排列，核膜清楚，瘤细胞内质网扩张，线粒体肿胀。

Results After EMR exposure, mitochondria swelled, the number of lysosome increased, nuclear chromatin marginated in neurocytes and neuroglial cells of the hippocampus and MrD. After exposure to EMR 1~3 h, surrounding space of capillarity enlarged and some endothelium cells of capillarity swelled; after the exposure 4~5 h, surrounding space of capillarity enlarged partially and vacuoles formed in endothelium cells.

结果 电磁辐射照射后，海马、边缘区组织中神经元、神经胶质细胞线粒体肿胀、溶酶体增多、核染色质边集；照射后即刻、1~3h毛细血管周围间隙增大，少数血管内皮细胞肿胀，4~sh毛细血管周围间隙部分增大，血管内皮细胞有空泡形成。

All experimental piglets revealed the characteristic nonpurulent encephalomyelitis,such as hyperemia,hemorrhage,edema in little vein and capillary v...

发病猪出现脑、脊髓的小静脉和毛细管充血、出血、水肿，神经原水肿、急性肿胀、急性液化及中央染色质溶解，胶质细胞轻微增生等非化脓性脑脊髓炎特征。

The results indicated that the typical apoptosis was induced by PRRSV in lungs and uteri. The ultrastructural changes showed different characterizations at different stages of the infection. During the early stage from 8th h to day 3 postinfection,the apoptosis cells shrank,the cytoplasm concentrated,the chromatin condensed,the kernel disaggregated and the endoplasmic reticulum dilated. During the middle stage from day 5 to day 9 postinfection,the apoptosis cells evidently shrank,the cell membranes protu berated,the plastosome manifolded,and apoptosis bodies were found. During the last stage from day 10 upwards postinfection,the apoptosis bodies degenerated and disappeared,and no inflammation occurred. Few apoptosis cells were necrotic.

结果表明，PRRSV可诱导宿主肺和子宫发生典型的细胞凋亡，表现为细胞的超微形态结构随着病毒感染进程出现不同的特征性变化，早期（感染后第8 h至第3 d）凋亡细胞多表现为细胞体积缩小，细胞质密度增强，染色质浓缩，核仁解体，内质网扩张；中期（感染后第5 d至第9 d）凋亡细胞体积显著缩小，细胞膜突起，线粒体增多，有凋亡小体形成；晚期（感染后第10 d以后）凋亡细胞形态多表现为凋亡小体降解和消失，少数凋亡细胞在凋亡晚期表现为坏死细胞。
