3. 2Case FN and inflammatory response -
female, 45 years old, underwent craniotomy to remove hemangioma, closed skull with titanium mesh, and all skin necrosis caused by surgical infection. There was no significant effect in hospital treatment for three years. 7 cm ×5 cm lesions were seen in the affected area, the skin in the middle was yellow and black necrosis, and exudation of purulent secretion was seen in the periphery. After using fn 20 days, the peripheral granulation grew well, FN mobilized phagocytes to clean the wound, inhibited bacteria and inflammation, and promoted the regeneration and repair of peripheral cells and tissues.
3. 3Case FN and angiogenesis
FN regeneration and repair of old rotten legs

And more accompanied by swelling of surrounding tissue, pigmentation, red color , erosion, ulcer face is dark red, with yellow purulent substance on the surface, purulent water smelly and smelly, dark skin around.
3.4 FN and granulation
FN regeneration and repair of old rotten legs
M ale, 43 years old, fell from the second floor during the construction of the house, causing paraplegia due to the transverse separation of the spinal cord. The bedsore on the buttock has not healed for more than 10 months, and the size of the wound is about 5cm * 5cm. A large amount of pus and necrotic tissue can be seen. The wound is treated according to the surgical routine, and sprayed once every 4 hours. The infection is controlled. The granulation of the wound is formed, and fibronectin FN is used consistently 36 days later, the wound healed completely without recurrence or scar hyperplasia.
