Result: The scores of motor functions in rehabilitative training group were significantly better than those in control group on the 7th d, 21st d and 35th d (P.05). Under microscope and electron microscope the nerve-cells of cortical infarct marginal zone in rehabilitative training group showed more integrity nuclear membranes, less agglutinative chromatin, clearer structures of mitochondria and more plentiful ribosomes on rough endoplasmic reticulum compared with that in control group.

结果：在造模后第7天、21天、35天时卒中训练组大鼠的平衡木及网屏测试评分分值均优于卒中对照组(P.05)；且于光镜、电镜观察下脑皮质梗死边缘区神经细胞的核膜较卒中对照组完整、核下凝集的染色质较为稀少，线粒体结构较为清晰，粗面内质网表面核糖体更为丰富。

Wilms tumors with unfaorable histology contain anaplasia – defined as the presence of hyperchromatic, enlarged nuclei (at least 3 times as large as blastemal nuclei), and multipolar mitotic figures.

如有细胞间变则提示Wilms'瘤预后不良，所谓细胞间变，表现为染色质粗糙，胞核增大（至少是后肾胚芽细胞核的3倍大小）以及多极性有丝分裂像。

It was noted that cell death from necrosis and autolysis would produce false-positive result because of non-specific DNA fragmentation.

提示类似泡状核细胞这类异染色质较少的细胞凋亡时可能都具有这种表现。

The operative area was examined with light microscope, electronic microscope, and the proliferating cell nuclear antigenwas detected. Results In CsA group, intraocular pressure was significantly lower than that in NS group(P＜0.05), and more functional filtering blebs were observed. Less fibroplasia and proliferative cells, less bioblast and less active caryotin in fibrocyte were found in CsA group than that in NS group. No serious mcomplicaton was found in both group.

结果 环孢霉素A组眼压控制多较理想，与对照组间的差异有统计学意义(P＜0.05)，大多数形成功能性滤过泡，光镜下见极少量纤维组织增生，电镜下见纤维细胞线粒体少，染色质功能不活跃，增殖细胞阳性率低，与对照组差异有统计学意义(P＜0.05)，且没有浅前房、视网膜损害等严重并发症。

In addition, spermiogenesis includes chromatin condensation, migration of the cytoplasm and mitochondria to the caudal pole of the nucleus, formation of a moderate axial nuclear fossa containing the proximal centriole and part of the distal centriole and presence of a short cytoplasmic canal separating mitochondria from the flagellum.

另外，精子发生过程中还包括染色质浓缩，细胞质和线粒体向细胞核的尾端迁移，在核的后端中轴位置上形成中等大小的核后凹，近端中心粒和远端中心粒的一部分嵌在核后凹之内，短的胞质内陷管将线粒体与鞭毛分隔开。

In addition, the mitochondria showed no signs of swelling and the nuclear membrane remains intact. Multiple membrane-bound apoptotic bodies and engulfment of cell debris and corpses by phagocytes were observed at 24h, while extensive cell loss appeared at 48h. These results demonstrated the occurrence of high level of apoptosis by 24h postdosing.

相应的超薄切片在电子显微镜下得到结果与光镜下一致，24h前线粒体形态结构无明显变化，主要有染色质浓缩、边集及分割，以及内质网空泡化和凋亡小体的形成；24h后可观察到线粒体的肿胀和扩张，细胞发生崩解和死亡。

RESULTS: The AF cells cultured in different substrates were morphologically undistinguishable. Toluidine blue staining showed that there was also no difference between AF cells cultured on flexible silicone membranes and in plastic plates. The cells growing in different substrates expressed the same levels of collagen typeⅠ,Ⅱ and aggrecan mRNA and integrin β1. AF cells grew well on silicone membranes.

结果：种植于不同基质的纤维环细胞形态学观察无明显差别；在两种基质上的纤维环细胞甲苯胺蓝染色无差异；Ⅰ，Ⅱ型胶原及聚集蛋白聚糖mRNA及细胞膜整合素β1的表达亦无明显差异；纤维环细胞可以黏附于硅橡胶膜上生长。

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。

Most sperm nuclei eventually developed into the male pronuclei, just like the normal sperms, except sperm nuclei in a few zygotes kept dense throughout the fertilization process. Dense chromosome body was seen at the nuclear area during the prophase of first mitosis, and in the middle of spindle at metaphase of first mitosis.

精子入卵后形成精核，大多能够逐渐解凝、液化并膨大，最终形成形态正常的雄性原核，但在第一次卵裂早期退化成浓缩的染色质小体，并在胞质分裂时随机地分配到其中一个子细胞里的分裂沟附近。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
