简介:摘要目的研究感染人体的细菌L型的分离培养,寻找一种培养细菌L型的最佳办法,以便临床鉴定与研究细菌L型。方法对在普通血液培养过程中瓶底出现轻微暗紫红、上清液微混或瓶壁有少量颗粒状物生长时,分别用血浆分离针抽取可疑培养物同时转种于普通血液琼脂培养基、L型增菌培养基及L型琼脂培养基中培养,观察其生长情况。结果在血琼脂固体培养基上最终形成了细菌L型,在液体培养基上形成了细菌型、L型、将可疑培养物再用血浆分离针转种于L型细菌液体培养基上又分离出23例L型细菌,使原来一般血培养阳性率提高。结论经过对细菌L型的分离培养研究,发现血琼脂固体培养基培养对于培养细菌L型有较好的效果,在临床上可以用于鉴定与研究细菌L型。

简介:试图以便识别HPTLC侧面(简历标记),在种类水平,为粗略的药的鉴定和证实,HPTLC分离在AervalanataL的不同部分上被开始。从南方印度。屏蔽的方法初步的phytochemical被Harborne的方法做。HPTLC研究被执行跟随Harborne和瓦格纳等方法。乙醇acetate-ethanol-water(8:2:1.2)为glycosides作为活动阶段被采用。结果A的茎,叶子,根,花和种子的methanolic摘录。lanata与范围0.02~0.86与23不同Rf价值显示出glycosides的23种不同类型的存在。当时,在glycoside的一般的更高的度,差异在植物的部分被观察了与繁殖部分相比。glycosides的最大的数字(12)在茎(9)跟随的根被观察了。礼品的结果学习的结论补充了拥有几的学习植物的民俗的用法知道并且有简历活动的未知bioactive混合物。由孤立并且识别这些bioactive混合物,新药能被提出治疗各种各样的疾病。
