The results indicate that the weak election-withdrawing group 4-hydroxymethyl in 4-position of pyridine in 4-HMDPA could weaken the fluorescence intensity of the lanthanide complexes. The contradistinctive experimental results show that the fluorescence intensities of these complexes are related to pH value of the aqueous solution and the dipole moment of solvent molecule: in the neutral aqueous solution,the fluorescence intensities of these complexes were strongest,while the less the dipole moment was,the stronger the fluorescence intensity was.

结果表明，在吡啶4位引入弱吸电子基团4-羟甲基会减弱稀土配合物的荧光强度；在水溶液中稀土配合物与溶液的pH值有着密切的关联，中性水溶液中荧光强度较大；分子偶极矩较小的溶剂中稀土配合物荧光强度较强。

In the unsterilized soil, the colonization of JMC1402P was affected by the physical and chemical factors of soil, and the aboriginal microbe would compete with it.The safety of releasing JMC1402P to the surrounding was tested, the design was as follows: mixing JMC1402P and R. huakuii JS5A16L, JMC1402P and Pseudomonas fluorescens Pf.X16L2 in filterable membrane, sterilized soil and unsterilized soil.

The results indicated that the content of cytosolic CaM in cells treated with exogenous Ca2+ has increased indistinctively, while fluorescence intensity in cells treated with TFP decreased. So we believed that exogenous Ca2+ has little effect on the expression of CaM. High concentration of TFP can enter yeast cells and combine to CaM to make it inactive, which is the reason that TFP restrain the growth of yeast cells. 5mmol/L EGTA could completely arrest the cell proliferation of MFP7 after 28h, when the fluorescence intensity in cells wasobviously increased with flow cytometry and LSCM.

被较高浓度TFP处理过的MFP7胞内荧光强度则相对较弱，推测是因为TFP进入胞内与CaM结合从而使其失活，这也是高浓度TFP抑制酵母细胞增殖的原因。5mmol／L EGTA处理28h左右后，酵母细胞的生长被抑制在G1晚期，此时通过细胞流式法和在激光扫描共聚焦显微镜下观察到胞内荧光强度显著高于对照，说明CaM的表达水平在G1后期开始上升；回加10mmol／L Ca~(2+)处理24h后，细胞开始恢复生长，细胞流式法测定胞内荧光强度有所下降，表明多数细胞完成G1／S转换，进入生长对数期。
