Objective To identify high resolution CT features of subacute or chronic hypersensitivity pneumonitis ,and to improve HRCT diagnostic accuracy. Methods Twenty one patients with subacute or chronic hypersensitivity pneumonitis were examined with pulmonary function testing,bronchoalveolar lavage,transbronchial lung biopsy,chest radiograph, and HRCT. Results On HRCT, 16 cases had evidence of small,indistinct,and centrilobular nodules, and the profusion of these nodules varied considerably. In 13...

Objective To identify high resolution CT features of subacute or chronic hypersensitivity pneumonitis ,and to improve HRCT diagnostic accuracy. Methods Twenty one patients with subacute or chronic hypersensitivity pneumonitis were examined with pulmonary function testing,bronchoalveolar lavage,transbronchial lung biopsy,chest radiograph, and HRCT. Results On HRCT, 16 cases had evidence of small,indistinct,and centrilobular nodules, and the profusion of these nodules varied considerably. In 13 cases, areas of ground glass densities were seen. 4 cases had areas of hypolucency. 5 cases had air trapping and mosaic perfusion. 2 cases had centrilobular emphysema . 2 cases had areas of pulmonary fibrosis. Conclusion High resolution CT can clearly show the type and distribution of abnormalities in patients with hypersensitivity pneumonitis. Indistinct centrilobular nodules and areas of ground glass densities,hypolucency together with centrilobular nodules on HRCT should suggest the diagnosis of subacute or chronic hypersensitivity pneumonitis.

目的 分析亚急性或慢性过敏性肺泡炎高分辨率CT(HRCT)的影像特征 ,以期进一步提高其HRCT诊断的准确性。方法  2 1例亚急性或慢性过敏性肺泡炎患者行肺功能、支气管肺泡灌洗、经支气管镜肺活检、胸部X线平片和HRCT。结果 HRCT图像上 1 6例表现出数量不等的边界模糊的小叶中心结节 ,1 3例可见磨玻璃样密度 ,4例有密度减低区 ,5例显示局限性的空气残留 (air trapping)并形成“马赛克”样灌注 ,2例出现散在的小叶中心性气肿、2例发生肺纤维化。结论 HRCT可以清晰显示过敏性肺泡炎病变的类型及分布。HRCT图像上表现为弥漫性边界模糊的小叶中心性结节或小叶中心结节与磨玻璃样密度及密度减低区同时存在时 ,应考虑亚急性或慢性过敏性肺泡炎的诊断

Objective:To investigate the chronic hypersensitivity(CHS) to dinitrofluorobenzene (DNFB) in metallothionein gene knocked out (MT-/-)mice and wild mice (MT+/+)with homologous genes.Methods:Mice were sensitized by applying DNFB on abdominal skin and CHS was induced on right ears .The CHS was observed by ear swelling.Results:In comparison with metallothionein—null mice, the ear swelling of normal control wild mice was significantly greater.( P <0.05 , Students t test).Conclusion:Metallothioneins play...

Objective:To investigate the chronic hypersensitivity(CHS) to dinitrofluorobenzene (DNFB) in metallothionein gene knocked out (MT-/-)mice and wild mice (MT+/+)with homologous genes.Methods:Mice were sensitized by applying DNFB on abdominal skin and CHS was induced on right ears .The CHS was observed by ear swelling.Results:In comparison with metallothionein—null mice, the ear swelling of normal control wild mice was significantly greater.( P <0.05 , Students t test).Conclusion:Metallothioneins play an important role in the CHS. Metallothionein gene knocked out (MT-/-)mice express less inflammation of CHS.

目的 :探讨金属硫蛋白 (metallothioneins ,MTs)在小鼠变应性接触性皮炎中所起的作用。方法 :用二硝基氟苯 (dinitrofluorobenzene ,DNFB)致敏金属硫蛋白基因敲除小鼠 (metallothionein -nullmouse,MT - /- ,不表达MT -I及MT -II)及基因同源对照野生型鼠 (MT + /+ ,正常表达MTs) ,并在小鼠右耳激发变应性接触性皮炎 ,分别对比两组小鼠激发后耳肿胀度。结果 :野生型鼠 (MT + /+ )耳肿胀度明显高于基因敲除鼠 (MT - /- ) ,统计学分析差异有显著性 (P <0 .0 5 ,t检验 )。结论 :MTs在迟发型变态反应的炎症过程中起重要作用 ,MT - /-小鼠不能完全表达迟发型变态反应的炎症。
