The in vitro effects of RU 28965 (roxithromycin), a new semisynthetic macrolide, on human neutrophil activity were compared with those of erythromycin. RU 28965, at a concentration as low as 0.1 microgram/ml, significantly enhanced the phagocytosis and killing of Staphylococcus aureus by neutrophils. Erythromycin displayed a less stimulating effect in a dose-dependent manner. Phagocytosis of Klebsiella pneumoniae was also increased after incubation of neutrophils with RU 28965, but killing was not altered. Neutrophil chemotaxis, myeloperoxidase activity, and O2 consumption were unchanged in the presence of RU 28965.
将新型半合成大环内酯类药物RU 28965(罗红霉素)与红霉素对人中性粒细胞活性的体外作用进行了比较。RU 28965在低至0.1微克/毫升的浓度下,能显著增强中性粒细胞对金黄色葡萄球菌的吞噬作用和杀伤能力。红霉素则呈剂量依赖性地表现出较小的刺激作用。中性粒细胞与RU 28965孵育后,对肺炎克雷伯菌的吞噬作用也增强,但杀伤能力未改变。在RU 28965存在的情况下,中性粒细胞趋化性、髓过氧化物酶活性和氧气消耗均未改变。
