We found that the new material; Polyvinylalcohl Silica Composite; is useful as a biomaterial.
In this material, the more the content of Silica, the less the degree of swelling and solubity. We also studied the tissue affinity of the material by the culture of fibroblasts and by the_Jhistnlogical response to the subcutaneously implanted materials.in the rabbits.
The results are summarized as follows; (1) The growth rate of fibroblasts increases with increasing the content of Silica.
(2)Silica-rich-composite has high tissue affinity.
