形态学

G/ml. After wt-p53 transfection and VCR treatment, the number of Bel-7402 cells was decreased; the cells were swollen severely with irregular projections; pyknosis, karyorrhexis and karyolysis were observed. After wt-p53 transfection, the expression of mdr1 and P-gp in Bel-7402 cells was down-regulated remarkably, and the expression of TopoⅡα was up-regulated.

形态学检查转染细胞，在VCR作用下细胞数明显减少，细胞散在不成片、细胞高度水肿、胞体不规则突起，可见核固缩、核裂解、核溶解。p53基因对Bel-7402细胞的mdr1/P-gp的表达有明显的抑制作用，对TopⅡα基因的表达有上调作用，对GSTπ、MRP基因表达没有影响。

Results: SOD of manipulation control group were higher than of model control group (P.05), scan icroscopic study indicated that kenn artilage degenerative level of manipulation control group were more sligh than of model control group.

结果：手法组SOD含量明显高于对照组(P.05)。关节软骨形态学观察显示手法组膝关节软骨退变程度明显低于对照组。

In the third part of the paper, the morphologic appear- ances of the radial keratotomy wound healing and debrided epithelial wound healing were studied by scan- ning electron microscopy , by transmission electron microscopy and by light microscopy.

Through archaeological research and morphological analysis of the knife handle and sword top, it is concluded that the Zhou-dated "feicui knife handle" as collected by LUO Zhenyu cannot be made of feicui, while admitting that it is most probably made from nephrite jade originating from Khotan, Xinjiang.

文章通过考古学研究和文物形态学分析和比较认为，罗振玉收藏的周代"翡翠刀柄"其材质不可能是翡翠，而最有可能是来自新疆和田的软玉；同时认为，将中国翡翠的自然历史溯源至周朝的结论缺乏历史学的和考古学的依据。

To explore the mechanisms of lead-induced apoptosis, PC 12 cells were exposed to 100 μmol·L-1 lead acetate for 24 h, and cellular morphology, cytoskeleton and ultrastructure were observed.

为了从形态学角度研究铅诱导细胞凋亡的机制，用100 μmol·L-1乙酸铅对PC12细胞进行染毒24 h，检测细胞整体形态、细胞骨架和细胞超微结构的改变。

According to the ultrastrucral observation of PMCs, three successively specific phases could be distinguished as leptotene, zygotene and pachytene in early prophase Ⅰ of Arabidopsis.

通过对拟南芥菜减数分裂前期花粉母细胞的形态学观察，我们认为在早前期Ⅰ中，拟南芥菜又可以分为三个时期：细线期、偶线期和早粗线期。

The image is first reduced in dimension by Gaussian pyramid, and the Hu moment is applied to the fixed sized overlapping blocks of low-frequency image. The eigenvectors are lexicographically sorted. Then, similar eigenvectors are matched by a certain threshold value. Finally, the area threshold value is proposed to remove the wrong similar blocks. The mathematical morphology operations are performed to locate the tampered part.

该算法首先将图像进行高斯金字塔分解，将低频图像进行块分解，提取每块的Hu矩不变特征，并将特征向量排序，然后为每个特征向量搜索符合阈值的相似特征向量；最后利用区域面积阈值去除错误的相似块，并结合数学形态学定位篡改区域。
