"胃不和"患者的痰液分析

目的:分析"胃不和"患者的痰液量及其细胞成分.方法:采用高渗盐水诱导痰液,并作细菌培养,常法计算痰液细胞总数,涂片姬姆萨染色检查细胞类型,测定受试者的呼气流速峰值(peak expiratory fliw,PEF).结果:"胃不和"患者的痰液量、痰液细胞总数、嗜酸性粒细胞数均高于正常对照组,诱痰后PEF下降.经中药治疗有80.0%的病人症状缓解,上述指标恢复至正常对照组水平,痰液细菌培养阴性.结论:"胃不和"可引起气道(非感染性)嗜酸性粒细胞性炎症.

Sputum analysis in patients with "disharmony of stomach"

Objective:To analyze the amount and inflammatory components of the sputum in patients with "disharmony of stomach", including gastroesophageal reflux disease, peptic ulcer and chronic gastritis. Methods: Sputum production was induced by inspiration of aerosol of 3. 5% hypertonic saline with ultrasonic nebulizer, and the total cell count in the sputum was examined. Sputum smear stained with Gimsa was used in differential counting under light microscope. Bacterial culture in the sputum was performed in the usual way. Peak expiratory flow (PEF) was tested to study the airway responsiveness. Results: The amount of sputum, the total cells and eosinophils in the sputum of the patients with "disharmony of stomach" were higher than those of the control. PEF decreased following sputum induction. These parameters returned to control level after treatment with Chinese herbs. Bacterial culture was negative. Conclusion:"Disharmony of stomach" can cause the bronchial inflammation (non-infection) characterized by eosinophil increase.
