Intraepidermal nerve fiber density (IENFD) after the treatment with ranirestat. (a) Representative photos of IENFs in diabetic rats treated with or without ranirestat. (b) Quantification of the IENFD revealed a significant decrease in untreated diabetic rats and the significant amelioration by ranirestat treatment. N: nondiabetic rats; D: diabetic rats; veh: rats treated with placebo; rani: rats treated with ranirestat. versus N treated with placebo, versus D treated with ranirestat, and –8 in each group. Scale bar: 50 μm.
