在这里，我们提供构建小鼠WBIS到CS的仪器所需的信息。系统安装后，调查人员根据动物中尼古丁或可替宁的交付剂量校准系统至关重要。该仪器包含一个定时器和压力计，可用于调节香烟泡芙量、泡芙频率、合并烟雾暴露期以及动物在每支香烟之间获得的休息间隔。此外，每天服用的香烟的实际数量可能因焦油和尼古丁含量而异。最后，必须定期清洁接触香烟烟雾的任何成分，以确保动物的烟雾?...

吸烟仍然是美国可预防疾病的主要原因之一，尽管在过去50-60年中吸烟的成年人数量持续下降。众所周知，吸烟与肺和血液的多种疾病有关，包括慢性阻塞性肺病（COPD），这是一组疾病，包括肺气肿和慢性支气管炎2、3、4。根据美国疾病控制中心（CDC）的数据，2014年，慢性阻塞性肺病是美国第三大死因，超过1500万美国人患有这种疾病。
CS最近也与患克隆造血症（CH）6、7的较高风险有关，在这种情况下，单个造血干细胞不成比例地产生一个人的外周血液的很大一部分。这一发现表明吸烟和骨髓功能之间有潜在的联系。鉴于CS对健康的广泛和非常重要的影响，鉴于穆林疾病模型是生物医学研究进步的基石，开发高效且经济实惠的系统来模拟小鼠的CS是有益的。
在这里，我们提供一个分步指南，建立一个负担得起的系统，用于治疗和研究CS对肺肺气肿和骨髓平衡的体内影响。此设备的组装不需要用户具有专业知识，因此允许 DIY 组装。

cigarette smoke exposure in mice using a whole-body inhalation system

据报道，2018年美国有近14%的成年人吸烟。香烟烟雾（CS）对肺部和心血管疾病的影响已得到广泛研究，然而，CS对血液和骨髓等其他组织和器官的影响仍然未完全确定。找到适当的系统来研究CS对啮齿动物的影响可能过于昂贵，需要购买市售系统。因此，我们着手构建一个经济实惠、可靠且多功能的系统，以研究CS在小鼠中的病理影响。这种全身吸入暴露系统 （WBIS） 设置通过交替接触 CS 和清洁空气来模拟香烟的呼吸和吹气。在这里，我们表明，这种自己动手（DIY）系统在接触了4个月的香烟烟雾后，在小鼠身上诱发气道炎症和肺气肿。使用这种仪器，CS的全身吸入（WBI）对造血干细胞和骨髓中的祖细胞（HSPCs）的影响也显示出来。

CS 暴露的主要特征之一是肺气肿，其特征是肺部气囊 （肺囊） 的损伤和破坏。因此，最初的实验侧重于DIY系统在反复接触CS后引起雌性小鼠肺部的肺部变化的能力。CS配药方案是根据我们先前的出版物选择的，我们利用此处描述的DIY系统用CS治疗小鼠，并研究肺气肿10、11、12、13、14、15、16的分子病理生理学。<sup class="...
