Abstract

The yellow sand is one of the phenomena of natural disasters often occurring in spring. In order to find out the influence on the eyes of the experimental animals by the yellow sand and its pathological histological findings, we went ahead with the research works. We used the yellow sand dust and non-yellow sand dust collected with the method of inhalation for the study materials and 100 rabbits breeded in the experimental animal farm of the Pyongyang Medical College for the subjects of the research works. The research method is to observe the influence by the yellow sand on the normal conjunctiva and cornea of the eyes of the rabbits, and on the damaged conjunctiva and cornea and to extract the eyeballs for the tissue samples in 24hrs after inserting 8.5mg of the yellow sand and non-yellow sand respectively in the experimental team and the contrast team and observe them with the method of the optical microscope. In conclusion, we proved that the yellow sand caused the conjunctivitis and keratitis in the eyes of the experimental animals and made clear the pathological histological findings of the conjunctivitis by the yellow sand. The pathological histological findings of the conjunctivitis by the yellow sand showed the significant inflammation cell infiltration with the main stress on the leucocyte and histocyte infiltration and edema and erosion.
