支气管黏膜下层的腺体肥大分泌黏液，支气管壁的破坏和脱水均有助于黏液栓的形成并阻塞哮喘病人的气道。

Briefly, coronal brain sections (100 mm)were cut with a vibratome, postfixed with 4% glutaraldehydein 0.1 mmol/L cacodylate buffer (pH 7.4) for 1 h, andthen with 1% osmium tetroxide in 0.1 mmol/L cacodylatebuffer for 2 h. After rinsing with distilled water, the brainsections were treated with 1% aqueous uranyl acetateovernight, dehydrated in an ascending series of ethanolsto 100%, followed by dry acetone, and then embedded inDurcupan ACM. Ultrathin sections (0.1 mm) were cut andstained with 3% lead citrate and subsequently examinedwith a Zeiss transmission electron microscope (Zeiss Inc.,Thornwood, NY, USA).

简单的说，先用切刀制成100um的冠状脑切片，然后用含有4%戊二醛在0.1 mmol/L的二甲砷酸缓冲液(PH7.4)中固定1小时后，放在含有1%四氧化锇的0.1 mmol/L的二甲砷酸缓冲液中2小时，接着用蒸馏水冲洗后，放在1%的aqueous uranyl acetate中过夜，接下来用梯度酒精(至100%)脱水，然后用丙酮干燥，再用Durcupan ACM包埋，切成0.1um的超薄切片后用3%的lead citrate染色，随后用透射电子显微镜观察。
