Results The clinical observation of 180 patients with entirely developed root apex of acute and chronic apical periodontitis shown that there was no significant difference comparing erythromycin ethylsuccinate-metronidazole-CP with FC in root canal sterilization, therefore, the irritability and poisonousness of the paste can be reduced by using erythromycin ethylsuccinate-metronidazole-CP instead of FC.

为了清除髓腔病源刺激物，促进根尖病变愈合，目前国内大多用甲醛甲酚进行根管消毒。甲醛甲酚属化学制剂，虽具有强烈的杀菌作用，但亦具有刺激性、毒性和抗原性等，而琥珀酸红霉素和甲硝唑在临床上已被证明对厌氧菌有明显疗效，对于根管内的消毒杀菌作用如何，研究报道不多。

Results The bletilla colloid was a homogenous viscous colloid whose relative viscosity was 2324.6 mm2/s. It was easily injected through 4-F catheter and hyperattenuating under fluoroscopy, meanwhile, with good histocompatibility and hemo-compatibility, without pyrogenetic response and toxicity. In vitro, the mixture of bletilla colloid and MMC did not produce separation and suspention phenomena but released 50%of MMC at 1.8h and 100%at 3.4h. The bletilla colloid mainly embolized peripheral arteries, maintaining occlusion for 5 weeks and without formation of collateral circulation. The injuries of normal hepatic tissues were slight, without hepatic cytonecrosis.

结果 (1)白芨胶为一种均质的胶状物，有一定粘滞性，相对粘度2 324.6 mm2/s，不透X线，易经4F导管注射；(2)白芨胶具有良好的血液相容性和组织相容性，无致热原性及毒性作用；(3)白芨胶-丝裂霉素C体外混合后，无分层及悬浮现象，释放MMC 50%约需1.8小时，100%需3.4小时；(4)白芨胶主要栓塞末梢小动脉，栓塞牢靠，维持时间可达5周，不易形成侧支循环；(5)白芨胶栓塞对正常肝组织损伤轻微，未出现肝细胞坏死。

Tribolium confusum and Rhyzopertha dominica. On the basis of the test. bulk grain treatment and surface treatment on the sacks of the stack were carried out. The results showed that INSECTO has good efficacy against the three tested insects. The effect of 0. 1% dosage of INSECTO can compared with that of 10ppm fenitrothion. INSECTO is more stable t...

在此基础上，又分别进行了围囤散装试验和包装粮垛麻袋表面喷洒防虫试验，结果表明，INSEC－TO对3种受试害虫均有较好的防治效果，以0.1％剂量拌和粮食其效果与10ppm杀螟松基本相同，但化学性质比杀螟松稳定且无化学药剂的毒性残留，对人畜更为安全。

In addition, this system can also be used for compound optimization, as well as IC50 testing. Using this system a series of compounds are identified that are effective Trypanosoma inhibitors without toxicity to human cells. Therefore, targeting tbLeuRS may represent a new venue for the development of anti-Trypanosoma drugs.

使用这一系统筛选到了对锥虫有较好抑制作用，但对人类细胞毒性较小的一系列新型化合物，因而锥虫亮氨酰tRNA合成酶很可能成为开发有效抗锥虫药物的新靶标。
