摘要:我们分析了两种喹诺酮类药物曲马沙星和环丙沙星对环磷酰胺(CP)诱导的白细胞减少小鼠造血器官再生和各器官细胞因子产生的影响。将其效果与G-CSF进行比较。环磷酰胺注射诱导了重度白细胞减少症,在注射后第4天达到最低点。所有喹诺酮和G-CSF处理的动物在最低点显示WBC>500/μL,而盐水处理的小鼠为50%。环磷酰胺诱导骨髓(BM)和脾脏中髓系祖细胞(CFU-C)数量显著减少。喹诺酮或G-CSF处理导致BM中CFU-C数量增加1.4-4.3倍;在脾脏中未观察到增强。CP处理导致骨干和脾脏中的集落刺激活性(CSA)增强,膀胱和肺中的活性降低。用喹诺酮类药物治疗CP注射小鼠在不同日期显著增强了骨干、脾、肺和膀胱中的CSA。
Abstract: We analyzed the effect of the two quinolones moxifloxacin and ciprofloxacin on the repopulation of hematopoietic organs and on the production of cytokines by various organs of cyclophosphamide (CP)‐induced leukopenic mice. The effect was compared to that of G‐CSF. Cyclophosphamide injection induced a severe leukopenia, with nadir at day 4 post‐injection. All the quinolone and G‐CSF‐treated animals showed WBC>500/μL at the nadir, compared to 50% of saline‐treated mice. Cyclophosphamide induced a marked decrease in the number of myeloid progenitors (CFU‐C) in bone marrow (BM) and spleen. Quinolone or G‐CSF treatment resulted in a 1.4–4.3‐fold increase in CFU‐C numbers in the BM; no enhancement was observed in the spleen. Treatment with CP resulted in enhanced colony‐stimulating activity (CSA) in bone shaft and spleen and decreased activity in bladder and lung. Treatment of CP‐injected mice with quinolones significantly enhanced CSA in the bone shaft, spleen, lung and bladder on different days.
