环丙沙星与氧氟沙星注射液治疗细菌性感染的疗效观察

以乳酸环丙沙星（ＣＰＬＸ）注射液和氧氟沙星（ＯＦＬＸ）注射液随机分组治疗各种细菌性感染４０例及４２例，并以注射用头孢噻肟钠（ＣＴＸ）治疗４９例作对照。三组平均年龄、体重、疗程及病情程度相比无显著性差异，具可比性。病种分布以消化道感染最多，共８１例，占总数的６１．８％。三组１３１例病人细菌阳性率为９４．７％。一疗程ＣＰＬＸ组、ＯＦＬＸ组、ＣＴＸ组治愈率分别为８７．２％、８３．３％、７１．４％，有效率     

氧氟沙星阴道泡腾片抗菌活性实验动物的研究

采用氧氟沙星（ＯＦＬＸ）阴道泡腾片和诺氟沙星（ＮＦＬＸ）阴道栓对临床常见的细菌性阴道炎进行了动物体内外抗菌活性测定。结果显示：体外测定组：ＯＦＬＸ对致病菌的ＭＩＣ在０１～３１２μｇ／ｍｌ而ＮＦＬＸＭＩＣ与其相近。体内测定组：ＯＦＬＸ的治愈率２ｍｇ／ｋｇ组为５０％，４ｍｇ／ｋｇ和８ｍｇ／ｋｇ组为１００％。而ＮＦＬＸ栓２ｍｇ／ｋｇ组为４０％，４ｍｇ／ｋｇ组为８０％，８ｍｇ／ｋｇ组为１００％，空白组治愈率为０。说明ＯＦＬＸ阴道泡腾片对此类阴道炎具良好的疗效，低、中剂量组略优于ＮＦＬＸ栓。但两药无统计学差异     

氧氟沙星在肾功能障碍大鼠唾液中的分布

目的 :研究肾功能障碍时氧氟沙星 (OFLX)在唾液中分布的变化规律。方法 :通过 5 / 6肾摘除术 ,制成大鼠肾功能障碍模型 ,以模拟手术为对照。OFLX( 10mg·kg-1)静脉注射后 ,经时采血及腮腺 (Pr)、颌下腺 (M )唾液。采用HPLC法测定各样品中的OFLX浓度。结果 :肾功能障碍使大鼠OFLX血浆浓度显著增高 ,全身清除率下降约 4 0 %。肾障碍组Pr唾液中浓度明显增高 ,而M唾液中浓度与对照组之间差异无显著性。在肾功能障碍组及对照组 ,消失相的OFLX唾液中浓度及唾液 /血浆浓度比 (S/P比 ) ,在Pr唾液均比M唾液高约 2和 3倍。肾功能正常大鼠的S/P比与Pr唾液中药物浓度之间呈良好正相关。结论 :OFLX在大鼠唾液中的分布存在腺差。肾功能低下 ,导致了OFLX向Pr唾液中的移行性增大 ,但对M唾液的影响不明显。而OFLX向Pr唾液中分布的量与该唾液中药物浓度有关。     

Studies on penetration of peroral new quinolone, levofloxacin to rabbit oral soft tissues with influence of stomachics sankyo magen mittel

It is a well-known fact that theoretically the absorption of new quinolones in the intestinal tract is significantly inhibited as a result of their interaction with metal cations. In order to study the effects of S. M powder, which is frequently used in the department of dentistry, on the tissue transfer of new quinolones, we administered S. M powder in combination with levofloxacin (LVFX) to rabbits and made comparative studies of soft tissue transfer rates. Prior to the initiation of the present study, we confirmed that there is a significant difference in tissue transfer rates of ofloxacin (OFLX) and LVFX, based upon the fact that LVFX is an optical activator of the OFLX. We obtained the following results in this study:
