摘要: 目的 对比研究6 种β-内酰胺类抗菌药物泰宁(TIN)、卡贝宁(CBN)、哌拉西林(PIP)、美洛西林(MZL)、头孢哌酮(CPZ)和头孢地嗪(CDZM)对2 种G-杆菌大肠埃希氏菌和绿脓假单胞菌的抗生素后效应(PAE)。方法 采用AVANTAGE 全自动分析仪, 应用光密度法测定PAE。结果与结论 美洛西林对大肠埃希氏菌的PAE 为负值或零, 对绿脓假单胞菌的PAE很小, 仅在4MIC 时PAE 达1h 左右;哌拉西林对大肠埃希氏菌和绿脓假单胞菌的PAE 均很小, 即使在4MIC 时PAE 也仅有0.3h 左右。在4MIC 以下时, PAE 与浓度依赖性不甚明显。头孢哌酮和头孢地嗪除了在4MIC 时对大肠埃希氏菌的PAE 可达1h 外, 其余PAE 均很短,甚至没有, 但随着抗菌药物浓度的增加, PAE 显著增加(P<0.05), 呈现部分浓度依赖性, 提示在较高浓度下可望产生相对明显的PAE。一般β-内酰胺类抗菌药物对G-杆菌PAE 较小,而泰宁和卡贝宁则较长。泰宁和卡贝宁的PAE 要显著长于其它4 种抗菌药物(P<0.05), 两药对大肠埃希氏菌和绿脓假单胞菌的PAE 均可达到1~3h, 同时卡贝宁的PA E 要显著长于泰宁。即使在1 倍MIC 时, PAE 亦显著长于其它4 种药物, 而在4 倍MIC 时则更长。两药对G-杆菌的PAE 在1/2 至4 倍MIC 浓度间呈显著的浓度依赖性。提示泰宁和卡贝宁可能具有与其它β-内酰胺类抗菌药物不同的PAE 产生机理。

Abstract: Aim The postant ibio tic effects (PAEs) induced by Tienam (TIN), Carberin(CBN), Piperacillin (PIP), Mezloci llin (MZL), Cefope razone(CPZ)and Cefodizime (CDZM)against Escherichia coli and Pseudomonas aerug inosa were investigated.Methods PAEs were determined by spect rophotome tric method.Results PAEs induced by MZL, PIP, CPZ and CDZM against escherichia coli and Pseudomonas aerug inosa were rather short(<1h).No PAEs or negative PAEs were even found in the results of MZL against Esche richia coli.In genaral, β-lactam antibiotics induced very short PAEs against Gram-negative bacilli.However, PAEs (1~3h)induced by TIN and CBN were markedly longer than those by the other four β-latams.PAEs induced by CBN were significant longer than longer than that induced by TIN. PAEs induced by CBN and CBN were obviously concent ration-dependent.Conclusion The results suggested there were multiple mechanisms for PAEs induced by β-lactams.The features of TIN and CBN should be emphasized when they are individually used to define drug dosing intervals in clinic.
