Effectiveness of filling structures within nerve guidance conduits in a rat sciatic nerve injury model.

Introduction: The gold standard treatment for peripheral nerve gap injury is nerve autograft transplantation. Although various nerve guidance conduits (NGCs) have been developed as alternatives to autografting, few reports have evaluated the effects of the internal structure of NGCs on nerve regeneration. We investigated how the internal structure of NGCs affects nerve regeneration.

Neurotropin® alleviates nerve damage in a mouse chronic nerve compression model.

Chronic nerve compression disorders, such as carpal tunnel syndrome, are common and can significantly impair daily activities due to motor and sensory dysfunctions. Currently, no systemic pharmacotherapy exists for preventing or treating disease progression. This study aims to investigate whether Neurotropin®, an established analgesic, has therapeutic effects.

Methylcobalamin-containing nanofiber sheets have better neuroprotective effects than small intestinal submucosa sheets.

Postoperative adhesion around nerves sometimes results in sensory and motor dysfunctions. To prevent these disorders, we have developed an electrospun nanofiber sheet incorporating methylcobalamin (MeCbl), an active form of vitamin B12 with anti-inflammatory and neuroregenerative effects. This study aimed to investigate the neuroprotective effects of MeCbl sheets against postoperative adhesion and to compare the effects of MeCbl sheets with those of porcine small intestinal submucosa (SIS) sheets using a rat sciatic nerve adhesion model.
