摘要: 目的: 采用全身体积描记检测系统(WBP)检测雾化吸入糜烂性毒剂2-氯乙基乙基硫醚(CEES)对小鼠肺功能的影响,为糜烂性毒剂导致肺损伤的病因诊断提供参考依据。方法: 将C57BL/6雄性小鼠随机分为对照组和CEES染毒组,CEES染毒组给予8% CEES雾化吸入,对照组雾化吸入等量无水乙醇溶剂,监测小鼠日常活动情况,检测72 h后小鼠体质量变化。应用WBP无创性检测肺功能各项指标差异,包括一般指标、潮气量、传导性指标、气道阻力指标、通气指标及每分钟通气量;采用HE染色检测肺组织病理学变化。结果: 与对照组小鼠相比,CEES染毒组小鼠活动减少,体质量显著下降(P<0.05);呼气峰值时间比率、最大吸气流速、呼吸频率指数、每分钟通气量降低(P<0.01),吸气时间、呼气时间、吸气末端暂停时间、呼气末暂停比、气道狭窄指数、呼吸暂停次数升高(P<0.01);HE染色结果显示CEES染毒组小鼠肺泡结构被压缩、肺间隔增厚、肺组织发生炎细胞浸润、肺泡内红细胞渗出。结论: CEES吸入后可导致小鼠吸气性和呼气性双向阻力增加,换气时间间隔延长,呼吸频率降低,引起肺通气不足。这些肺功能特点对糜烂性毒剂导致的肺损伤具有辅助诊断价值。

Abstract: OBJECTIVE: The aims were to study effect of an inhalation blister agent,2-chloroethyl ethyl sulfide (CEES),on the pulmonary function of mice by the whole body plethysmography (WBP) technology,and to provide an etiological evaluation of lung injury caused by the agent. METHODS: Male C57BL/6 mice were randomly divided into control and CEES exposure groups. The exposure group was given an aerosolized 8% CEES solution,while the control group was expose to an equal dose of solvent ethanol. The daily activity of the mice was monitored,and after 72 hours,the body weights were recorded. WBP was applied to non-invasively detect differences in various lung function characteristics,general indicators,tidal volume,conductivity indicators,airway resistance indicators,ventilation indicators,and minute ventilation. Hematoxylin-eosin (HE) staining was used to detect pathological changes in lung tissue. RESULTS: Compared with control mice,the CEES-exposed group showed reduced activity and a significant decrease in body weight;rate of achieving peak expiratory flow,peak-inspiratory-flow,frequency,and minute volume decreased (P<0.01);inspiration time,expiration-time,end-inspiratory-pause,time of pause at end of expiration,pause enhanced,and pause increased (P<0.01);compressed lung alveolar structures,thickened lung septa,infiltration of inflammatory cells in the lung tissue,and entrance of red blood cells into the alveoli. CONCLUSION: Inhalation of blister agents led to increased inspiratory and expiratory bidirectional resistance,prolonged ventilation intervals,decreased respiratory rate,and pulmonary hypoventilation. These may be characteristics of blister agent-induced lung injury.
