With the competent germinating epicotyl of cotton as receptor in exogenous gene transformation, NPTII (neomycin phosphotransferase Ⅱ) gene carrying selection marker and GFP reporter gene were mediated into cotton by agrobacterium-mediated transformation. The pre-culture time, bacterial-immersing time, co-culture time and antibiotics concn., etc of using agrobacterium-mediated transformation in the transformation of competent germinating epicotyl of cotton were studied.

方法］以棉花感受态萌动的上胚轴作为外源基因转化的受体，用农杆菌介导法将携带有筛选标记NPTII基因及GFP报告基因导入棉花，研究了农杆菌介导法用于棉花感受态萌动上胚轴转化的预培养时间，浸菌时间，共培养时间及抗生素处理浓度等。

The bioactive screening on aldose reductase, nitric oxide synthetase, liver cancer Bel-7402, cavum oris epithelioma KB and colon cancer HCT-8 showed that paeoniflorin inhibited the nitric oxide synthetase by the rate of 83. 4% at the concentration of 5μg/ml, and paeoniflorigenone inhibited the colon cancer HCT-8 cells by the rate of 83. 2% at the concentration of 5μg/ml.

通过醛糖还原酶、NO合酶、肝癌Bel-7402、口腔上皮癌KB以及结肠癌HCT-8五种模型的生物活性筛选表明，在51μg／ml的浓度下，芍药甙对NO合酶的抑制率达83.4％，芍药甙元对结肠癌HCT-8细胞株的抑制率达83.2％，有较好的抑制作用。

The protein encoded by RBB1 contained two conserve domain ATP-synt-DE-N and AtpC from 3 to 83 and from 1 to 133. All above showed that the full length cDNA RBB1 encoded ATP synthase CF1 epsilon chain protein The plant resistant mechanism is very sophisticated and one of the mainly responses is the metabolic change.

植物的抗病机理非常复杂，其主要反应之一就是代谢上的变化，例如，在利用cDNA微阵列对水稻抗稻瘟病近等基因系的分析中，检测到了很多与光合作用和糖代谢功能有关的差异表达片段；在小麦中也筛选到一个植物中ATP酶具有高度同源性的cDNA序列可能与小麦抗白粉病相关。

In this study, we screened antibacterial activities of 50% ethanolic extracts 87 traditional Chinese medicines to penicillin-resistant Staphylococcus simulans, and used disc agar diffusion method, broth dilution method determination of minimum inhibitory concentrations. The results showed that Equisetum hiemale L.

在这项研究，我们筛选了经50%乙醇萃取的八十七种传统中药材对产生青霉素抗药性Staphylococcus simulans进行抗菌活性检测，使用琼脂纸锭扩散法和连续稀释法来判断最小抑制浓度，结果发现木贼Equisetum hiemale L。

Single factor and orthogonal design were respectively utilized to optimize extracting process of ergosterol from fermentated rice of Monascus.
