组织发生的

The microstructure in the heat--affected zone consists of coarse bar-shape recovery grain, and that of the thermo-mechanically affected zone exhibits bent band-like character, but the deformation degree at the advancing side is bigger than that at the retreating side. Microstructures in TMAZ are also recovered, and the amount of recovery grain at retreating side is more than that at advancing side.

热影响区组织发生回复和粗化反应，形成粗大的棒状回复晶粒；热机影响区组织发生弯曲变形，但整体上仍保留带状组织形貌，前进侧热机影响区组织变形程度高于后退侧，该区同时还发生回复反应，且后退侧热机影响区内的回复晶粒数量多于前进侧。

B Of the six basic media MS, MS1/2 (half-strength of MS salts and vitamins), WPM, DKW, B5 and SH, MS1/2 was the most proper one to induce somatic embryos. Somatic embryos generally regenerated directly from excised zygotic cotyledons. PGRs combination affected somatic embryogenesis significantly. Medium with NAA 1mg/L, TDZ 0.05mg/L, IBA 2—10mg/L combined with BA 10mg/L, or IBA 10mg/L integrated with BA 0-2mg/L gave the highest induction rate. Excised zygotic hypocotyls had the strongest potential to produce callus. Callus induction was also affected significantly by media and PGRs. The proper callus induction condition was MS1/2 medium containing NAA 1mg/L, IBA 10mg/L, BA 2-5mg/L and TDZ 0.05mg/L. Harvest period affect somatic embryogenesis significantly. Zygotic embryo explants collected from the end of July to the middle of August had strong potential to generate somatic embryos, when endosperm finished solidification, different parts of the embryos were completely formed, the size of embryos occupied about 2/3 of the embryo sac. Provided with optimized conditions, direct somatic embryogenesis rate can attain to 33. 68%, and callus induction rate of hypocotyls was up to 90.7%. Cytological observation on megasporogenesis and zygotic embryogenesis of Manchurian ash showed that the ovary was twicarpellum, twilocular with two ovules each loculus. The ovule was tenuinucellar and anatropous, with one megasporcocyte. The development of embryo sac is of the Polygoum type.

Objective To explore livin, MTA1 and the caspase3 protein expression, their correlation and clinical pathology in colon cancer Methods The expressions of livin, MTA1 and caspase3 protein in 88 cases of colon cancer were detected by immunohistochemistry stainingResults Livin, caspase3 protein and MTA1 positive expression rates in colon cancer tissues were more than those in tissues beside the cancer Furthermore there were obvious relevance between livin protein, MTA1 positive expression rate and degree of histodifferentiation and lymph node metabasis and between caspase3 protein positive expression rate and degree of histodifferentiation of colon cancer Caspase3 protein expression had prominent inverse correlation with the livin expressionConclusions ①Over expression of livin having inhibtion on colon cancer is one of important factors of colon carcinogenesis ②Caspase3 protein expression in colon cancer tissues is inhibited to less and has prominent inverse correlation with livin expression Accordingly, suppressing caspase3 protein activity is one of channels, by which livin promotes colon carcinogenesis ③MTA1 plays the important role in histodifferentiation degree and lymph node metastasis of colon cancer

采用免疫组织化学染色方法检测88例结肠癌组织中Livin，Caspase3 及MTA1的表达情况。结果（1）结肠癌组织中Livin的阳性表达率显著高于癌旁组织，且Livin的表达与结肠癌的组织分化程度及淋巴结转移程度显著相关。（2）结肠癌组织中Caspase3蛋白的阳性表达率显著高于癌旁组织，且Caspase3蛋白的表达与结肠癌的组织分化程度显著相关。（3）结肠癌组织中MTA1的阳性表达率显著高于癌旁组织，且MTA1的表达与结肠癌的组织分化程度及淋巴结转移程度显著相关。（4）Caspase3蛋白的表达又与Livin的表达呈显著负相关。结论（1）Livin在结肠癌组织中过表达，它可能是促进结肠癌发生的重要因素之一。（2）Caspase3蛋白在结肠癌组织中表达被抑制而降低，且与Livin的表达呈负相关。因此，抑制Caspase3蛋白的活性是Livin促进结肠癌发生的途径之一。（3）MTA1对结肠癌的组织分化及淋巴转移发挥重要作用。
