【摘要】 １９８８～１９９０年间，用光镜、电镜、电子探针微分析技术与临诊检查法，对甘肃省河西地区８１７头动物的肺和支气管淋巴结进行了研究。首次发现这一地区动物的尘肺存在。各种动物病变的发生率如下：猪２４．５％（２５／１０２），绵羊１．７％（２／１１６），山羊１２．６％（９／７１），鸡６０（１５／２５）和马３９．２５％（病死率）。其组织特征是多发性间质性肺炎灶和大量含尘巨噬细胞结节。这些巨噬细胞尘粒的主要元素是Ａｌ和Ｓｉ。此外在猪肺中有明显的支气管周炎，而牛和家兔的尘肺病变很轻。研究表明，上述病变的发生，和这一地区环境（厩舍和空气）中的粉尘含量高有关。作者还讨论了尘肺的病理发生和组织变化。更多还原

【Abstract】 Studies on the lungs and bronchial lymphonodes of 817 animals from Hexi corridorin Gansu province were carried out by light microscope, electron microscope, electronprobe microanalytic technique and clinical examination in 1988￣1990. It was first foundthat pneumoconiosis occursred in animals of the area. The incidence of lesions in vari-ous species of animals was as follows: swine24.5% (25/102), sheep-1.7% (21/116),goat-12.6% (9/71), chicken-60% (15/25), and horse-39.26% (case fatality rate).It was histopathologically characterized by multi-foci of interstitial pneumonia with largenumber of dust-laden macrophage nodules. Aluminium and Silicon were the predominantelements in the dust particles of the macrophages. In addition, there was obvious Perib-ronchitis in the lung tissues of pigs. The pneuinoconiosis was mild in cattles and rabb-its. The studies show that occurence of abovementioned lesions are related to the moredust contents in the invironment (stable and air) in this area. Pathogenesis and histolo-gical lesions of the pneuinoconiosis were also discussed.更多还原
