200IU BTX-A was dissolved in 8ml normal saline, and the solution of BTX-A was injected into 8 different points in urinary sphincter using a flexible cystoscopic needle, with each point of 1ml solution. The effects was evaluated and followed up. Result: One month after injection, the hydronephrosis decreased from 3.9±1.2cm to 1.1±0.8cm and PUV did so from 187±58ml to 54±18ml in all patients.

The ethanol extract was dissolved with HCl, the acidic extract was basified to pH9-10 with NH_3-water and extracted with CHCl_3 to give total alkaloids. five alkaloids were isolated with column chromatography and preparative thin-layer chromatography, and three of them were identified as dehydrocorydaline、 corynoline and dihydrosanguinarine on the basis of spectral analysis MS,~1H-NMR,~(13C-NMR and physicochemical properties. All of them were found for the first time from this plant.

为研究灰绿黄堇的化学成分，本文将灰绿黄堇乙醇提取物采取酸提取、碱游离后萃取的方法得到总生物碱，然后利用柱色谱、制备薄层色谱等方法分离、纯化了灰绿黄堇中5种生物碱，并利用IR、MS、~1H-NMR、~(13)C-NMR等方法鉴定了其中的3种，分别为去氢紫堇碱、紫堇灵、二氢血根碱，均为首次在此植物中发现。

The chemistry behavior research of wollastonite indicated that the silicon-potassium fertilizer has a chemical active in organic acid.The factors affecting manurial effect of silicon-potassium fertilizer are not only soil pH and desilicification,but also content and type of organ in the soil.Wollastonite chemistry behavior indicates that silicic acid can be dissolved out from silicon-potassium fertilizer in chlorhydric acid solution if pH of solution is not smaller than 2. The drop of apparent density,increase of DBP sorptive rate and specific surface for leavings indicate that hydrated silicon oxide is polyporous,and those mineralogic feature presignify that silicon-potassium fertilizer has a role of conservation of both Moisture and Fertility and improving soil structure.After active ingredient releasing,silicon-potassium fertilizer leaves half the substance (non-active ingredient)in soil.

熟料单矿物在酸溶液中的化学行为研究表明，硅钾肥矿物在有机弱酸中的化学活性较好，影响硅钾肥肥效发挥的因素是土壤pH值和土壤的去硅化程度，还有土壤有机质的含量与种类；硅灰石在盐酸溶液中化学行为表明，在反应体系pH不小于2的情况下，硅钾肥矿物大量溶出硅酸根组分；溶解残余物表观密度降低、DBP吸着率和比表面积增加表明水合二氧化硅是以多孔形式存在，为硅钾肥具有保水保肥、改良土壤结构的提供了矿物学依据。

The results show that SO2 gas itself does not influence the growth of ZY-1, however, when the SO2 concentration is higher than 50×10^(-6), ZY-1 growth rate and its CO2 fixation rate are all lowered and the pH of the medium is decreased, so measures must be taken to desulphurize or control pH of medium temporality. The presence of NO with concentrations of lower than 300×10^(-6)did not influence the growth of ZY-1 and its CO2 fixation, NO absorbed in the medium is utilized as a nitrogen source. The influence of dissolved soot dust on ZY-1 growth and its CO2 fixation could be ignored once the soot dust in the stack gases was disposed by the original method.

结果表明，烟气中的SO2是以增加培养液中的SO2^(-2)浓度及降低pH的形式来影响ZY-1的生长及其对CO2的固定的，当其浓度大于50×10^(-6)时，需要进行烟气脱硫或控制培养液pH变化来消除其影响；烟气中NO浓度不高于300×10^(-6)时，不影响ZY-1的生长及其对CO2的固定，反而可作为氮源供ZY-1生长用；对经过一般除尘处理的烟气来说，在利用小球藻ZY-1固定CO2时可不考虑溶解性烟尘的影响。
