WebTreatment with 0.6 mL/kg and 2 mL/kg CPCGI markedly reduced the axonal and myelin sheath injury compared with vehicle-treated rats (axon: both P < 0.05; myelin sheath: P < 0.01 and 0.05, respectively). Our data showed dose-dependent protective effects of CPCGI on the white matter damage due to CCI. spohn ranch
