Results There were a lot significant differences in mice between sexes and ages. There are significant differences on the seroenzyme activity of the p21(superscript HBsAg/HbsAg)、p21(superscript HBX/HBX) transgenic mice and Wild-types.

结果 p21(上标 HBsAg/HBsAg)和p21(上标 HBsAg/HBsAg)转基因小鼠不同年龄、不同的指标雌雄之间差异显著，并且随着年龄的变化，雌雄之间的变化规律不同。

Objective To obtain the basic data of seroenzyme activity of p21(superscript HBsAg/HbsAg) and p21(superscript HBsAg/HbsAg) transgenic mice on the different age, and To study the infection of the seroenzyme activity, of the p21(superscript HBsAg/HbsAg) and p21(superscript HBX/HBX) was introduced into p21 locus of the mouse.

目的 测定p21(上标 HBsAg/HBsAg)和p21(上标 HBsAg/HBsAg)转基因小鼠纯合型及野生型小鼠的血清酶，探讨各种血清酶在两种纯合型小鼠及野生型小鼠的变化规律。

Under inverted microscope, stereognosis of neurons died down, there were blank bulb in the neurons, dark particle were seen in the neuritis; the result of MTT test showed that the survival rate of neurons was obviously decreased. Res 40μmol/L increased the survival rate of neurons. Aβ(subscript 25~35) dose-dependently increased the level of MDA, decreased the level of GSH. Res dose-dependently increased the level of GSH, decreased the level of MDA.

结果：Aβ(下标 25~35)在终浓度为2μmol/L时神经元形态有明显的变化，细胞立体感减弱，胞体内空泡形成，细胞突起内可见黑色颗粒状物；细胞的存活能力明显下降，与对照组相比较有显著性差异(P.05)；Res在终浓度40μmol/L时，能明显提高细胞的存活能力。Aβ(下标 25~35)可以明显升高细胞培养上清液中MDA含量，降低GSH的含量；Res可使细胞培养上清液中MDA含量下降，GSH含量增加。

But, there was no Ca(superscript 2+) precipitate in tapetal cells of Zhenshan 97B at the pollen mother cell stage and the meiosis stage and the Ca(superscript 2+) precipitates in tapetal cells mainly deposited in the disaggregated cytoplasm.

而保持系绒毡层细胞遮花粉母细胞时期和减数分裂时期细胞内没有Ca(上标 2+)沉淀；单核花粉时期绒毡层细胞内的Ca(上标 2+)沉淀主要分布在解体的细胞质内。

The results showed that the interaction between temperature and pH value had a significant effect on the growth of thiobacillus ferrooxidans.

研究结果表明其最优适宜环境为：pH=2、温度28℃、初始Fe(上标 2+)+浓度0.15mol/L、初始Fe(上标 3+)浓度为0.06mol/L。

The effects of pH value, temperature, the initial concentrations of Fe(superscript 2+) and Fe(superscript 3+) as well as the interaction between these factors on the growth of thiobacillus ferrooxidans were investigated by orthogonal tests.
