Abstract

Unlabelled: Aims/Introduction:  Advanced glycation end-products (AGE) have been implicated in the development of diabetic neuropathy. It still remains unknown, however, how AGE cause functional and structural changes of the peripheral nerve in diabetes. To explore the role of AGE in diabetic neuropathy, we examined the peripheral nerve by injecting AGE into normal Wistar rats.

Materials And Methods:   Young, normal male Wistar rats were injected intraperitoneally (i.p.) daily for 12 weeks with purified AGE prepared by incubating D-glucose with bovine serum albumin (BSA). A control group received BSA alone. A group of rats given AGE were co-treated with aminoguanidine (50 mg/kg/day, i.p.). Peripheral nerve function and structure, as well as nerve Na(+),K(+)-ATPase activity, were examined in these rats. Immunohistochemical expressions of 8-hydroxy-2'-deoxyguanosine (8OHdG) and nuclear factor-κB (NF-κB)p65 were also examined.

Results:   Serum AGE levels were increased two to threefold in the AGE-treated group compared with those in the BSA-treated control group. AGE-treated rats showed a marked slowing of motor nerve conduction velocity (MNCV) and decreased nerve Na(+),K(+)-ATPase activity compared with those in the BSA-treated group. These changes were accompanied by intensified expressions of 8OHdG and NF-κBp65 in endothelial cells and Schwann cells. Aminoguanidine treatment corrected MNCV delay, Na(+),K(+)-ATPase activity, and suppressed the expression of 8OHdG and NF-κB, despite there being no influence on serum AGE levels.

Conclusions:   The results suggest that an elevated concentration of blood AGE might be one of the contributing factors to the development of neuropathic changes in diabetes.
