Logistic re.re.sion was use. to re.ate.e.plana- tory variable. （such as social, inve.tm.0}t, fore.t production, biophysical and proxim.ty factors） with susce.tibility to de.ore.tation to construct pre.ictive.m.de.s with two focuse.： ge.e.al and by bioge.graphical zone.In all m.de.s, de.ore.tation has positive.corre.ation with distance.to rainfe. agriculture. and ne.ative.corre.ation with slope. distance.to roads and distance.to towns.

目的:评估左氧氟沙星、加替沙星及莫西沙星等新氟喹诺酮类药物对肺结核患者的早期杀菌活性及延长早期杀菌活性。设计:随机开放临床试验。40例成年新诊断的涂阳肺结核患者(每组10例)分别每日单一接受异烟肼300m.,或左氧氟沙星1000m.,或加替沙星400m.,或莫西沙星400m.的7天治疗。治疗前2天及单药治疗7天期间,每日收集痰液进行定量培养。计量单药治疗开始的头2天(0-2天)及治疗后5天(2-7天)的菌量下降情况,以评估各药的早期及延长早期杀菌活性。对实验室工作人员关于病人治疗分组信息采用单盲法。结果:异烟肼的早期杀菌活性为0.67log10cfu/毫升/天,高于莫西沙星(0.33log10cfu/毫升/天)及加替沙星(0.35log10cfu/毫升/天)。与每日1000m.左氧氟沙星的早期杀菌活性(0.45log10cfu/毫升/天)相比,无统计学差异(P=0.14)。3种氟喹诺酮类药物的早期杀菌活性(0-2天)与延长早期杀菌活性(2-7天)相似。总体说来,氟喹诺酮类药物的延长早期杀菌活性高于异烟肼。结论:莫西沙星、加替沙星及高剂量左氧氟沙星,虽然略低于异烟肼,但均有良好的早期杀菌活性,并具有较高的延长早期杀菌活性。有理由对这些药物敏感的结核病人进行进一步的治疗研究。
