Light microscope and transmission electron microscopy showed that SMMC-7721 cells induced by SAHA had undergone the restorational alteration in morphology and ultrastructure, which were different from those of nontreated cells but were similar to those of normal cells, and the changes were as follows: the cells turned to be flat and spread; the nucleo-cytoplasmic ratio lessened and nuclear shape became rather regular; the number of nucleolus reduced and its volume lessened; euchromatin increased while heterochromatin decreased in nucleus; in the cytoplasm, mitochondria grew in number with relatively consistent structure and well-developed mitochondria cristae; Golgi complex turned to be well-developed and typical; rough endoplasmic reticulum increased. Immunocytochemistry assay showed that the expression of AFP and PCNA were declined significantly. FCM analysis showed SAHA could arrest SMMC-7721 cells in G0/G1 phase, with an accumulation of the cells in G0/G1 phase while a decrease of cells in S phase. Semi-quantitative RT-PCR detection revealed that the expression of p21WAFl mRNA was upregulated remarkably in the cells treated with SAHA.

结果：倒置显微镜和透射电镜观察显示，经SAHA处理的细胞增殖速度显著减慢，细胞体积增大，细胞核较小，形状较为规则，核仁数量减少、体积变小，核内常染色质增多而异染色质减少，核质比例减小，细胞质内线粒体数量增多、线粒体嵴发达，高尔基体较为典型，粗糙型内质网增多，呈现出与正常上皮细胞相似的形态变化；MTT比色法测定结果显示不同浓度(2.5、5.0、7.5、10.0uM)SAHA对SMMC-7721细胞的增殖均有抑制作用，并有明显的剂量依赖和时间依赖关系；免疫细胞化学检测显示SAHA能显著降低PCNA和AFP在SMMC-7721细胞中的表达；流式细胞仪检测结果显示，SMMC-7721细胞经SAHA处理后，G0/G1期细胞明显增加，S期细胞则明显减少，细胞被阻滞于G0/G1期；RT-PCR检测结果表明，SAHA作用12h后SMMC-7721细胞中p21WAF1 mRNA的表达即有增加，24h后更为明显。

He experiment proved that pre-implantation embryos are more sensitive than post-implantation ones, suggested TCDD may exert its effect before implantation, or at this process. 3. The toxicity of TCDD on the early embryo can be of omnifarious. It can strongly inhibit DCR, which represent mother toxicity; It cause un-synchronizated cleavage of pre-implanted zygote and pre-implanted embryo loss; It also decreases implantation sites in the uterus, and continued to effecting the uterus of pregnant mouse, cause the decreased number of fetus before birth. 4. TCDD exposure changed reproductive hormone level of pregnant mouse.

CDD对胚胎的毒性影响可能是多方面的：强烈抑制子宫蜕膜细胞反应，表现出典型的母体毒性；虽然没有影响胚胎转运速度，但造成着床前胚胎的丢失和发育不同步；早期染毒降低了第9天的胚胎着床数，同时使出生前第18天胚胎成活数继续减少。
