Figure 1.

Effect of sericin on neurofilament proteinexpression in sciatic nerves of diabetic rats (immunohistochemistry, × 200).

Neurofilament protein positive products were presented as brown yellow particles.

(A) High levels of neurofilament protein expression were observed in the sciatic nerve of control rats.

(B) Significantly reduced levels of neurofilament protein expression were observed in the sciatic nerve of model rats.

(C) Levels of neurofilament protein expression were significantly increased following sericin treatment in diabetic rats.
