单次口服200毫克氧氟沙星后其在人肺组织中的渗透情况。 (你提供的原文中多了一个of,正确的应该是Penetration of ofloxacin... 这里按照修正后的翻译)

Abstract

The penetration of ofloxacin into lung tissue was studied in 10 patients subjected to pulmonary surgery. Samples of blood and lung tissue were obtained 3 to 8 h (mean, 5 h) after oral administration of 200 mg. The mean level in tissue was 2.17 +/- 0.5 micrograms/g, while the mean level in serum was 0.85 +/- 0.23 micrograms/ml. The mean lung tissue/serum concentration ratio was 2.55 +/- 0.30. The achievable levels of ofloxacin in lung tissue are above the MICs for most pulmonary pathogens.

摘要

对10例接受肺部手术的患者研究了氧氟沙星在肺组织中的渗透情况。口服200毫克后3至8小时(平均5小时)采集血液和肺组织样本。组织中的平均水平为2.17±0.5微克/克,而血清中的平均水平为0.85±0.23微克/毫升。肺组织/血清浓度平均比值为2.55±0.30。对于大多数肺部病原体,肺组织中可达到的氧氟沙星水平高于其最低抑菌浓度。
