庆大霉素血浓度微生物测定法的改进 [PDF]

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 1990
以短小芽胞杆菌为检测菌,以生理盐水配制庆大霉素标准液,用校正抑菌圈直径计算血清庆大霉素浓度。结果表明:庆大霉素的MIC为0.5μg/ml,在1~16μg/ml内,抑菌圈直径与血药浓度对数呈线性相关。平均回收率为103%,但β-内酰胺类MIC均在100μg/ml以上。本法简便,不用血清配标标准液,不必应用β-内酰胺酶,结果准确,可满足临床监测庆大霉素血药浓度要求。

Synthesis of Novel Bicycloβ-Lactams As Potential β-Lactamase Inhibitors [PDF]

open access: yes, 2005
β-内酰胺类抗生素是临床上最常用和品种最多的一类抗生素,它们为保护人类的健康、延长寿命发挥了巨大的作用。但是,随着β-内酰胺类抗生素的广泛使用,细菌逐渐对其产生了耐药性,从而使得一些β-内酰胺药物的疗效大大下降。其中β-内酰胺酶的产生是细菌对该类抗生素产生耐药性的主要机制。研究发现,在对待由产生耐药性的细菌所引起的感染时,将β-内酰胺酶抑制剂与降低疗效的β-内酰胺类抗生素联合使用,会保持甚至加强β-内酰胺类抗生素的抗菌活性。因此,积极开发新的β-内酰胺类抗生素和高效、广谱的β ...
