Journal of Medical Postgraduates 2015;(6):590-593
O bjective Different degrees of oxidative stress may exist in patients with diabetes mellitus (DM).The aim of this study was to explore the roles of oxidative stress and the level of vascular endothelial growth factor ( VEGF) in the development and progression of DM in the rat model of type 1 DM (T1DM). Methods We established the T1DM model in 23 male SD rats and in-cluded another 17 in the control group .We determined the total anti-oxidation capacity ( T-AOC) and the levels of super-oxide dis-mutase (SOD), glutathione (GSH), and malondialdehyde (MDA) by chromatometry, and measured that of VEGF by ELISA. Results At 7 weeks after modeling, the level of fasting blood glucose(FBG) was significantly increased in the T1DM rats as com-pared with the controls ([23.01 ±3.62] vs [5.08 ±0.46] mmol/L, P<0.05); the levels of GSH and SOD were markedly lower (18.8 [0.36] vs [3.82 ±1.05] g/L and [192.06 ±34.57] vs [242.37 ±32.79] U/mL, both P<0.05) while those of serum MDA and VEGF remarkably higher in the T1DM than in the control rats ([4.94 ±0.63] vs [4.42 ±0.37] nmolm/L and [23.97 ±1.84] vs [22.32 ±1.71] pg/mL, both P<0.05);no statistically significant differences were found in T -AOC between the two groups (P>0.05).FBG was correlated positively with MDA (r=0.51) and VEGF (r=0.47) but negatively with GSH (r=-0.71) and SOD (r=-0.40), while serum VEGF positively with MDA (r=0.32) and negatively with GSH ( r=-0.34 ) in the experimental rats . Conclusion Peroxidation is increased and the anti-oxidation mecha-nism weakened during the development and progression of T 1DM, which is closely related to hyperglycemia .High VEGF is associated with hyperglycemia and enhanced peroxidation .
