本文对X线胸片呈弥漫性间质性肺疾病48例,并以仅有呼吸道症状,X线胸片和纤支镜检查无异常病人7例做对照,进行支气管—肺泡灌洗和支气管—肺泡灌洗液(BALF)的细胞学检查。结果:BALF细胞总数:研究组均高于对照组;细胞分类计数:致纤维化肺泡炎嗜中性粒细胞(21.3±20.2%),明显高于对照组(P<0.01);过敏性肺泡炎和肺结节病淋巴细胞,均明显高于对照组(P<0.01)。认为BALF细胞检测对弥漫性间质性肺疾病的诊断、鉴别诊断及分类具有一定临床意义。
In this paper, 48 cases of diffuse interstitial lung disease were observed on X-ray, and 7 patients with only respiratory symptoms, X-ray and fiberoptic bronchoscopy without abnormalities were used for broncho-alveolar lavage and bronchial- Cytological examination of BALF. Results: The total number of BALF cells in the study group was higher than that in the control group. The number of cells in the group was significantly higher than that in the control group (21.3 ± 20.2%, P <0.01). Allergic alveolitis And pulmonary sarcoidosis lymphocytes, were significantly higher than the control group (P <0.01). It is of clinical significance that the detection of BALF cells in the diagnosis, differential diagnosis and classification of diffuse interstitial lung disease.
