矽肺实验研究中对胶原组分的分析表明,矽肺开始阶段血清羟脯氨酸(Hypr.)上升,矽肺进展阶段时纤维化的肺组织中Hypr.明显增多。根据组织放射自显影的一些资料看,矽结节的扩大是由于结节边缘附上新胶原的结果。实验性矽肺加上结核感染时并不引起
Analysis of the collagen components in the silicotic experimental study showed that the Hypr. Increased in the initial stage of silicosis and significantly increased in the fibrotic lung tissue during the progression of silicosis. According to some data on autoradiography, the expansion of silicone nodules results from the attachment of new collagen to the nodal edges. Experimental silicosis with tuberculosis does not cause infection
