巴布膏对豚鼠哮喘模型基质金属蛋白酶-9及其抑制物水平的影响

目的通过检测巴布膏处理哮喘豚鼠模型肺组织中基质金属蛋白酶9(MMP-9)及其抑制物(TIMP-1)的含量,以了解巴布膏对哮喘治疗的效果。方法选取50只豚鼠随机分成4组:正常对照组(NC)、哮喘对照组(AC)、必可酮治疗组(BC)、巴布膏治疗组(BA)。除 NC 组腹腔注射生理盐水外,余组均应用卵蛋白致敏建立豚鼠哮喘模型。BC 组给予必可酮喷雾剂每天2揿(0.25mg/kg),BA 组则用巴布膏贴于豚鼠背部脱毛区双侧肺俞及脾俞穴,用胶布固定6h,每天给药1次,共14天。应用 Wright-Giemsa 染色和免疫组织化学方法分别测定不同组别豚鼠支气管壁内嗜酸性粒细胞和肥大细胞数,并测定肺组织的 MMP-9、TTMP-1阳性细胞百分数(A/P)和平均光密度值(AOD)及计算阳性指数(PLI=AOD×A/P)。结果 BA 组、BC 组动物支气管壁内嗜酸性粒细胞和肥大细胞数量均高于 NC 组,而低于 AC 组(P 均<0.05)。各组间 MMP-9的各指标差异有显著性(P 均<0.05),其中 BA 组、BC 组 MMP-9的 A/P、AOD 和 PLI 均高于 NC 组,而低于 AC 组(P 均<0.05);然而4...

Effect of Babugao on Matrix Metalloproteinase-9 and Its Inhibitor in Asthmatic Model of Guinea Pig

Objective To study the effect of Babugao (BBG,a new anti-asthmatic adhesive plaster) on asthma by measuring the change of levels of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) in lung tissue of guinea pig asthmatic model.Methods Fifty guinea pigs were randomly divided into 4 groups,the nor- mal control group (A),the model group (B),the becotide treated group (C) and the BBG treated group (D).Except those in Group A were treated with normal saline,all the an...
