Therefore, this study was undertaken to determine whether CAPE, by virtue of its antioxidant properties, could affect lipid peroxidation, nitric oxide (NO), Paraoxonase (PON-1) and the oxidant/antioxidant balance in the sciatic nerve of Streptozotocin (STZ)-induced diabetic rats. The rats were treated as follows: control; this group of rats (n = 9) received isotonic solution. Diabetic (STZ, untreated diabetic): STZ 50 mg kg(-1) b.wt. was given intraperitoneally for the induction to this group (n = 8). Diabetic+CAPE treatment (STZ+CAPE, CAPE-treated diabetic): diabetic rats (n = 8) received CAPE (10 mu mol/kg/day) for a period of 21 days beginning one week after the STZ administration. Biomarkers; Malondialdehyde (MDA), Total Oxidant Status (TOS), total antioxidant status (TAS), PON-1 and NO levels for oxidative stress in sciatic nerve of the rats were measured. We found a significant increase in MDA, NO and TOS levels along with a reduction in TAS levels and PON-1 activity in the sciatic nerves of the STZ-induced diabetic rats (at p<0.001). The MDA, TOS and NO levels in sciatic nerve were significantly reduced in the CAPE-treated diabetic group compared to the untreated diabetic group (at p<0.05). In conclusion, the results of this study demonstrated that CAPE exhibits protective effects against oxidative damage in the sciatic nerve tissues of diabetic rats.eninfo:eu-repo/semantics/openAccessDiabetic RatSciatic NerveOxidative StressCurcuminArticle86577581WOS:0003169774000182-s2.0-8486613524310.3923/ijp.2012.577.581N/AQ4
