摘要：
A nerve dysfunction repairing material including a hydrogel of a polysaccharide derivative that has, in a 0.5 wt % aqueous solution, a complex modulus of 1 to 1000 N/m2 and a loss factor of 0.01 to 2.0 as measured at an angular velocity of 10 rad/sec using a dynamic viscoelasticity measuring apparatus. The nerve dysfunction repairing material can be a hydrogel injectable through a syringe, has excellent retention in the body, and has a restorative effect on the function of damaged or degenerated nerves.
