Abstract:: |
The changes of fibronectin (FN)and laminin (LN) in the rat lungs irradiated locally with 30Gy were observed by light microscopy, electronmicroscopy and immunohistochemistry . The results indicated that distribution of FN and LN in the irradiated lungs was random, the content of FN apparently increased in early phase and gradually decreased in late phase, and the content of LN increased all the way in various degrees.The results suggest that FN is mainly related to the generation and development of early pathological changes in radiation pulmonary injury, whereas LN is related to its entire process . |
