The reseach on activity changes of SOD, POD and CAT during the somatic embryogenesis of Y35 showed:(1) The activty of SOD was from 52.98 to 133.20 U·g-1·h-1, and remained a rising trend after early single embryo forming, this revealed that SOD might be positively correlated to the differentiation of embryogenic cell and the development of somatic embryo.(2) The activty of POD was from 0.05 to 0.50 U·mg-1·min-1, ascended firstly and desceded later, and was highest in embryogenic callus and lowest in late single embryo , this revealed that POD might be positively correlated to the division and differentiation of proembryo mass, while negatively correlated to the development of PEMⅢto late single embryo.(3) The activty of CAT was from 0.86 to 2.81 U·mg-1·min-1, showed an up-down-up trend, reaching to the highest peak at the time of early embryo formating and decreasing to the lowest at the time of early cotyledonary embryo formating, this revealed that CAT might be positively correlated to the development of early single embryo, while negatively correlated to the formation of middle single embryo and early cotyledonary embryo.The changes in activty of SOD, POD and CAT indicated these three antioxidant enzymes coregulated the differentiation and development of embryogenic cells during Larix somatic embryogenesis.4. Differentially expressed cDNA libraries of the stages of proembryo mass and somatic embryo maturation were successfully constructed by suppression subtractive hybridization.

对Y35体细胞胚胎发生过程中抗氧化酶活性变化的研究显示：(1)SOD活性在52.98~133.20 U·g-1·h-1之间，并在早期单胚形成后一直保持上升的趋势，表明其与胚性细胞的分化及体细胞胚的发育均具呈正相关；(2)POD活性在0.05~0.50 U·mg-1·min-1之间，呈现出先下降后升高的趋势，在胚性愈伤组织中最高，而在后期单胚形成时降至最低，表明其与原胚团的分裂和分化呈正相关，但与PEMⅢ向后期单胚的发育呈负相关；(3)CAT活性在0.86~2.81 U·mg-1·min-1之间，表现出升-降-升的变化趋势，在早期单胚形成时升至最高，在早期子叶胚形成时降至最低，表明其与早期单胚的发育呈正相关，而与中期单胚和早期子叶胚的发育呈负相关。

During sexual differentiation, mitochondria and smooth endoplasmic reticulum in cells of testis also increase in quantity, but it is less than that in ovary, they disintegrate after sexual differentiation. The big grana always exsist in course of sexual differentiation, but small grana don\'t appear.

分化时精巢细胞的超微结构显示线粒体和内质网数量也有增加，但不如分化中卵巢细胞的数量多，分化后线粒体和内质网解体，在整个分化过程中大颗粒一直存在，无小颗粒出现。

Meanwhile,HDAC1 acetylation level is significantly increased.The overexpression of HDAC1 can promote erythroid cell proliferation and inhibits induced differentiation,the knockdown of HDAC1 or 2 inhibits erythroid cell proliferation and promotes induced differentiation.We also found that HDAC1 affects GATA1 mediated transcription activity.Thus our data revealed that HDAC1 may negatively regulate GATA1 mediated transcription and suggest that the dynamic regulation of GATA1 associated NuRD/MeCP1/HDAC1/HDAC2 complex may determine the onset of erythroid differentiation programs.Moreover,this study will eventually help to design new therapeutic approaches in treatment of leukemia.

研究发现在被诱导分化的小鼠红细胞白血病细胞中与GATA1相结合的HDAC1被乙酰化并失去活性，在血细胞中过表达HDAC1能够促进血细胞的增殖并抑制分化，反之在血细胞中敲除HDAC1或HDAC2能抑制血红细胞的增殖并促进分化，而且HDAC1能够负调控GATA1的转录活性，GATA1与NuRD/MeCP1复合体之间的动态调控，决定血红细胞分化的发生和发展，并为探索白血病的致病机理奠定了理论基础。

Background: The stem cell is a kind of cell which can keep alive for a long term and has a few of differentiation potencies.

Basing on the Graf′s addition theorem, two expessions, interior and exterior expression, are deduced and the suitable problems for them are discussed. It has been found that the interior expression is the main point for sovling the scattering problem of circular inclusion in half-space. It also has been found that the exterior expression is the key for the scattering problem of circular arc canyon and circular arc alluvial valley, and is one of the main points for scattering problem of circular arc hill as well.

从Graf原有加法公式出发，本文给出了其内域型和外域型两种表达形式并讨论了这两种表达的适用范围，同时指出：内域型表达是求解半空间内含夹塞区出平面散射问题的要点，而外域型表达是解决任意圆弧型凹陷地形和任意圆弧型沉积盆地出平面散射问题中求解难点的关键，同时也是克服任意圆弧型凸起地形出平面散射问题求解困难的要点之一。
