| Research Abstract |
We changed material of vitrigel to add to collagen sponge in atero collagen derived from a pig from native collagen derived from a cow. As for the tissue rate of absorption, atero collagen is faster than native collagen. We took the quantity of effective atero collagen as 2.2mg/cm2 for epithelium regeneration. The quantity of atero collagen which was necessary for epithelial regeneration was 2.2mg/cm2.
The observation of the post transplantation trachea lumen used rigid endoscope for ears.
Hereby, an evaluation of the epithelization was possible without resecting trachea.
