Study of Influencing Effects of UV on the Lung After Infected with Bacteria Pseudomonas Aeruginosa

Abstract

Ultraviolet radiation has many uses in the field of medicine and treatment, so it has been identified as an important factor in treating or reducing the severity of bacterial infection. The ultraviolet rays have effect on the mice infected with the bacteria Pseudomonas aeruginosa, and how the rays worked on killing the bacteria. The study focused on the tissue structures of lung, after treated with the UV. It's caused acute defects in tissue structures of lung, of treated white mail mice. After the end of experimental period, the blood samples collecting, then the animals sacrificed for histological study, The current result showed normal alveolar wall with prominent epithelial layer that lining the inner surface of alveoli, the result noted prominent bloody congestions between of alveoli, most tissue sections of lung were normally after treated, but noted some lesions of emphysema The tissue section of lung in this group appeared the positive role of UV rays in treated the pathological lesions the result noted the lung parenchyma was normal in structure except some of blood congestion in different location of lung parenchyma, the figure showed little infiltration cells which situated between the lesions of blood congestions these results have better histological structures compared with infected group, but something similar to control group.
