[Structural organization of blood serum in occupational respiratory diseases].

The authors demonstrated that in workers having pulmonary dust diseases, serum blood dehydration ("closed drop" preparation) reveals in polarized light very specific structure different from that in the reference group members. Morphologic properties of various structures could prove silicotic process development.

[Changes in blood serum liquid crystal structure under experimental silicosis].

To study changes in liquid crystal structure of blood serum, the authors used intratracheal model of experimental silicosis in rats exposed to DQ12 quartz dust. Early stages of disease demonstrated changes in blood serum structurization, seen in polarized light. Morphology of those changes could serve as a characteristic of silicotic process intensity.
