Inhibition of Hyperpolarization-Activated Cation Current in Medium-Sized DRG Neurons Contributed to the Antiallodynic Effect of Methylcobalamin in the Rat of a Chronic Compression of the DRG

Figure 2

Continuous treatment of MeCbl inhibited bilateral mechanical allodynia of CCD rats. Continuous treatment of MeCbl (1.25 mg/kg and 2.5 mg/kg) or Mannitol (2.5 mg/kg) was injected intraperitoneally from the 3rd postoperative day (black line segment).
