| Outline of Final Research Achievements |
The acceleration of nerve regeneration remains a clinical challenge. We previously demonstrated that transcutaneous CO2 application using a novel hydrogel increases the oxygen concentration in local tissue via an “artificial Bohr effect” with the potential to prevent muscle atrophy. In this study, we investigated the effect of transcutaneous CO2 administration on limb function after peripheral nerve injury in a rat sciatic nerve injury model. Rats were divided into a sham group, a control group or a CO2 group. CO2 was administered percutaneously for 20 min five times per week. In this study, good results were obtained in the CO2 group compared with the control group from behavioral evaluation, nerve conduction study, analysis of messenger RNA (mRNA) expression, wet muscle weight and histological analysis.Transcutaneous CO2 application has the therapeutic potential to accelerate the recovery of muscle atrophy in peripheral nerve injury.
