Granulosus is further;2. In differentiation of closely relatedspecies, the changes in heterochromatin and pericentric inversions are key factors, this is wellnoted in the small chromosomes;3. A. mantzorum has well-differentiated XY type sex chromo-'.omes, the Y chromosome is mainly composed of euchromatin, but has strong C-band in themiddle of the long arm. It is suggested that the Y chromosome of A. mantzorum is in the-initial stage of sex chromosome differentiation.
结果表明：(1)四川湍蛙、理县湍蛙和棕点湍蛙之间的亲缘关系较近，而它们与棘皮湍蛙的亲缘关系较远；2）在近缘种的分化中，染色体结构异染色质的变化和臂间倒位是重要的因素之一，这在小型染色体上表现得尤为突出；四川湍蛙具有在形态上分化很明显的性染色体。C带分析表明，此性染色体主要由常染色质构成，但在其Y染色体的长臂上存在明显的中间C带，推测尚处于性染色体分化的初期阶段。

所有细胞核的最显著的特点就是染色体，由DNA和组蛋白所组成的染色质构成，DNA绕行在由4个相似的组蛋白分子结合而形成的柱状的芯上，这一结构称为核小体，核小体之间由连续的DNA链连接，形成串珠样结构，进一步盘曲形成常染色质或异染色质。

Mitochondria was relatively little in size. Round primary lysosome with high electron-densed granules and secondary lysosome with high or low electron-densed granules were seen frequently. DCs contained many rough endoplasmic reticulum, the Golgi apparatus and ribosomes. The vacuoles with flocculent electron-densed granules were rare. Some special granules in cytoplasm were seen, whose surface like earphone were covered with a membrane. High electron-densed contents in the granules were near one side and the other side was bright. The nucleus became markedly small in volume, nephroid or hoofed in shape. The nucleus had little euchromatin and lots of heterochromatin under nuclear membrane.

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。
