The results showed that the sheep had fibrinous pneumonia and lymphocyte interstitial pneumonia, which were typical pathologic changes of this disease. Remarkable changes were observed in the lung: fibrinous exudates, infiltration of inflammatory cells, pleura thickening, interstitial edema, hemorrhage and formation of thrombiand lymph clot. The heart, liver and kidney had different degeneration degree. Reactive hyperplasia presented in bronchales lymphonodi.

结果发现该病例具有胸膜肺炎的典型病理变化，呈现纤维素性肺炎和淋巴细胞性间质肺炎，纤维素性物质的渗出和炎性细胞的浸润很明显，肺胸膜增厚，同时在肺间质还可见水肿、出血、血栓和淋巴栓的形成；另外心、肝、肾也均有不同程度的变性，淋巴结呈反应性增生。

Experiments for controlling the soil matric potential of 0～-20 cm soil layer by use of irrigation and drainage have been conducted with lysimeters to study its effect on dry matter accumulation, nutrition and grain yield of winter wheat .

研究结果表明，小麦抽穗初期、乳熟期和完熟期的干物质累积均在土壤基质吸力30～40kPa下最多，小麦地上部对氮，钾的吸收量以及籽粒产量在土壤基质吸力30～40kPa下最高。

Results were shown as followings:(1) Sodium selenite at 0～2.5 μmol/L significantly increased the antioxidative capacity of L-02 cells without having remarkable impact on SMMC-7721 cells;(2) Sodium selenite at concentrations above significantly increased telomerase activity, hTERT gene expression and telomere length of L-02 cells without significant impact on SMMC-7721 cells;(3) Sodium selenite at higher concentrations (larger than 5 μmol/L) resulted in peroxidation of L-02 cells, while scutellarin significantly counteracted its effect;(4) Selenium-rich amino acids from silkworm pupas in the range of 0.5～2.5 μmol/L Se significantly inhibited SMMC-7721 cell growth, induced apoptosis and cell cycle change, and the generation of reactive oxygen species. In contrast, sodium selenite and selenomethionine only had weak impact on them at the same concentrations;(5) A new selenium-containing protein was found from selenium-rich silkworm pupas, which is worthy to be study further;(6) An expression vector containing ansense RNA of hTERT gene were constructed and used to transfect SMMC-7721 cells. They were observed to inhibit hepatoma cells.

结果如下：（1）0～2.5μmol/L亚硒酸钠显著性增强L-02细胞的抗氧化能力；而对SMMC-7721细胞的作用不显著；（2）该浓度硒显著性提高L-02细胞端粒酶活性、增强hTERT基因表达和延长细胞端粒长度；而对SMMC-7721细胞的作用均不显著；（3）高浓度硒（5μmol/L以上）显著性抑制L-02细胞生长、致细胞过氧化，灯盏花素能拮抗硒所致过氧化、降低硒毒性；（4）0.5～2.5μmol/L富硒蚕蛹氨基酸显著性抑制肝癌细胞SMMC-7721生长、导致细胞凋亡和周期改变、诱导细胞产生活性氧，同浓度亚硒酸钠和硒代蛋氨酸对其抑制不显著；（5）富硒蚕蛹蛋白经分离纯化和鉴定后发现存在一新含硒蛋白，其结构和功能有待研究；（6）通过已有的含hTERT基因质粒，成功构建hTERT反义RNA表达质粒，转染SMMC-7721细胞后对其生长具有抑制作用。

Resembled to control oocytes, MAPK was inactivated after cytoplasts activation. However, after activation the cytoplasts showed fragmentation while pronuclei were formed in the control oocytes. This indicated that nuclei play important role in maintainence of oocytes normal morphology.

成熟胞质的活化与卵母细胞相似，在活化后MAPK被迅速灭活，只是胞质在活化处理后均发生碎裂，而卵母细胞活化后形成原核，这表明核在细胞形态维持中起重要作用。

The slightly negative δ^30Si values of both thick-bedded and anatase-rich siliceous rocks are similar to those of hydrothermal and biogenic siliceous rocks. The ranges and mean values of δ^18O values are similar.

两种硅质岩的δ^30Si值为变化较小的负值，与热水沉积和某些生物成因硅质岩的硅同位素组成相似，两者的δ^18O值范围和平均值均相似。

Several strategies have been applied to achieve this goal previously, such as lipidsome or polymer encapsulations, gene gun, in situ electroporation. Chemicals with a permeable...
