Inorganic fibers in lung tissue from patients with pleural plaques or malignant mesothelioma.
比较了恶性间皮瘤和胸膜斑患者与无癌症或慢性呼吸疾病患者肺中无机纤维的浓度，发现组间有显著差异。
The concentration of inorganic fibers in the lungs of patients with malignant mesothelioma and pleural plaques has been compared to that of patients without cancer or chronic respiratory diseases. The fiber concentrations have been determined by scanning electron microscopy and given as number of fibers per gram of dried tissue. A statistically significant difference in inorganic fiber content was found between the different groups.
