The inhibitory activity of Echcin to 14 strains of phytopathogenic bacteria was tested using paper plate method.

采用纸碟法测定了Echcin 对5 个属植物病原细菌共14 个菌株的抑制作用，琼脂稀释法测定了Echcin 对12 种植物病原真菌的抑制作用，在此基础上开展了Echcin 对番茄早疫病和稻白叶枯病的温室盆栽试验，同时开展了Echcin 对小麦纹枯病的田间小区试验。

The purpose of this study is to screen microorganisms with growth inhibition against plant fungal pathogens. The plate-dilution method was used to isolate the bacteria from salt marshes at Dafeng, Jiangsu. The antifungal activity of the bacterial broth filtrates against 5 phytopathogens was determined using mycelial disk method. The antifungal compositions of four active bacteria were analyzed primarily with chromatography techniques. Two hundred and thirty-five aerobic (92) and anaerobic (143) bacterial strains have been isolated from the coast salt marsh and sixty-five strains, of which 39 are aerobic and 26 are anaerobic showed greater than 30% of inhibition rate against the growth of at least one of the phytopathogenic fungi on petri dish.

为了开发对植物病原真菌生长有抑制作用的药源微生物，本实验采用平板稀释法从江苏大丰盐沼湿地土壤中分离微生物，并通过菌丝块法检测这些微生物代谢产物对5种植物病原真菌生长的抑制活性，进而利用柱层析分析其活性成分；结果共分离得到235株细菌，其中好氧细菌92株，厌氧细菌143株；体外活性测试结果显示有65株至少对1种测试植物病原真菌的抑制率在30%以上，其中好氧菌39株，厌氧菌26株。

The benzene fraction of the liquid-liquid partitioning was found to be the most active against the larvae of Plutella xylostella and Pieris rapae, with the rate of antifeeding, at ×50 dilution, of 97.7%and 97.3%, respectively, after 12 h exposure.

液—液分配法中，苯提取物的拒食活性最高，在50倍稀释浓度下，小菜蛾Plutella xylostella和菜粉蝶Pieris rapae幼虫对其拒食率分别为97.7%和97.3%。

But the systemic investigation in geriatric patients about it is very little in civil, people still have different opinions about its performing methods, the degree of tolerance et al, and its reliability and effectiveness of saving blood also has to be more discussed.6% Hydroxyethl starch(200/0.5) is a new generation of artificial colloid, and posses the unique effect of blocking for leakage of blood capillary except that it can obviously expand blood volume and ameliorate microcirculation filling and oxygen supply, and its incidence of harmful response is very low within clinicaldosage, so it is a better plasmatic substitute that was used in preoperative AHH and volume therapy at present.

6％羟乙基淀粉(Hydroxyethl starch，HES)是临床广泛应用的新一代人工胶体，扩容效果好，维持循环稳定时间长，输注后能明显改善微循环灌注和组织氧供，并具有独特的毛细血管渗漏封闭效应，且不良反应少，过敏反应低，是目前血液稀释和容量治疗较理想的血浆代用品。

The method is used to preconcentrate Li and separate matrix in geological samples, and contents of Li in those samples determined by ID-ICP-MS, giving precise of 3% and good accurate results.

分离后 ，用 ICP-MS测定锂同位素的比值，具有较高的测量精密度。用同位素稀释电感耦合等离子体质谱测定地质样品中微量锂，结果相对标准偏差 sr%。方法检出限低，精密度高，分析速度快，是测定锂的较理想方法。

For L. barbarum transformation, the optimized procedure was using 3-week-old leaf explants, preculture for 3-4 days, infection with 1∶1 dilution of an overnight culture of EHA101 (pIG121Hm) suspension with AS and co-culture for 3 days at 24℃ in the dark.

Howeer, in one of their cited references, Hur et al,2 adocate the use of acute NH combined with hypotensie anesthesia and other techniques as safe and effectie in limiting homologous transfusion in spinal fusion surgery.2 In this series, only 4 of 119 (3.4%) patients required homologous transfusion by using not only NH and the cell saer but also autologous predonation, hypotensie anesthesia, continued postoperatie hemodilution, and transfusion indicated by clinical judgment.

在此研究系列中，119例中只有4例（3.4%）患者在应用了NH和洗血球机并进行了自体血的预先输注，麻醉性低血压和术后的血液稀释技术只好根据临床判断仍需要异体血的输注。
