Abstract
A spinning solution composition which provides regenerated silk fiber that exhibits a strength and elongation close to those of natural silk fiber, is rapidly degradable in vivo, and can be caused to have ability to gradually release a drug to prevent inflammation; a process for producing such regenerated silk fiber by use of the composition; and regenerated silk fiber obtained through the process.
