Figure 5.

Effect of sericin on neuropeptide Y expression in anterior horn cells of diabetic rats (immunohistochemistry, × 200).

Neuropeptide Y positive products were presented as brown yellow particles.

(A) Low levels of neuropeptide Y expression were observed in anterior horn cells of control rats.

(B) Significantly increased levels of neuropeptide Y expression were observed in anterior horn cells of model rats.

(C) Levels of neuropeptide Y expression in anterior horn cells of diabetic rats were significantly decreased following sericin treatment.
