The postantibiotic leukocyte enhancement (PALE) of meropenem in vitro in comparison with that of imipenem was evaluated with 24 recently isolated gram-positive and gram-negative strains. In general, pre-exposure to carbapenems (at four times the MIC for 2 h) led to increased polymorphonuclear cell phagocytic killing. The PALE of imipenem was generally significantly less than that observed with meropenem.
使用24株最近分离出的革兰氏阳性和革兰氏阴性菌株,评估了美罗培南与亚胺培南相比的体外抗生素后白细胞增强(PALE)作用。一般来说,预先暴露于碳青霉烯类药物(在最低抑菌浓度的4倍下作用2小时)会导致多形核细胞吞噬杀伤作用增强。亚胺培南的PALE通常明显低于美罗培南。
