Protein amyloid beta (A?), as the pathologic hallmark of Alzheimer disease (AD), increases in the brain of diabetic patients. The aim of this study was to investigate the effect of 6 weeks of voluntary wheel running combined with allium paradoxum extract on cortex amyloid beta (A?1-42) levels in diabetic rats induced with alloxan. For this purpose, 42 male wistar rats (weight 185+1 gr, 8 weeks old) were assigned randomly to 6 groups (n=7): normal control (c), training (T), control – diabetic (CD), diabetic – training (DT), diabetic – allium (DA), diabetic – allium – training (DAT). Subjects were diabetes through alloxan injection (120 mg/kg dissolved in saline) intraperitoneally. Training and diabetic – training rats inhabited in cages performed their training voluntarily on a running wheel for six weeks. At the end of the protocol, cortex A?1-42 in T and DT groups decreased. A?1-42 levels significantly decreased in T and DT compared with C and CD respectively (P<0.001). Also, A?1-42 levels significantly increased in CD in comparison with C (P<0.001). Furthermore, voluntary training along with consumption of allium paradoxum extract decreased cortex A?1-42 in DAT (P<0.001). Voluntary training and allium extract had positive effects on decreasing A?1-42 levels; therefore, it can be recommended as therapeutic strategy for diabetes.
