[A primitive study on the histological changes in the lungs of residents in the wind-sand area of Gansu Province].

ABSTRACT

395 residents in a wind-sand area were examined with chest radiographs. Silicotic roentgeno- graphic changes were shown in 28 cases. The abnormal finding rate of the > 40 years old age group was 21%. The histological findings of lungs from a camel lived in that area for 20 years also confirmed that the cause of death was silicosis.
