Abstract
Background: Diabetes is a common disease that for its treatment and control different methods are recommended such as the use of natural remedies and lifestyle modification. Since the use of herbal medicines have less side effects than many chemical drugs, hence, this study aimed to investigate the effect of cinnamon extract on blood glucose, insulin and insulin resistance in diabetic rats with streptozotocin. Materials and Methods: This experimental study was conducted on 40 adult male rats, that were randomly divided into 4 groups including non diabetic control, diabetic control and two experimental groups receiving doses 60mg/kg of cinnamon extract for 3 and 6 weeks. At the end, by phlebotomizing of rats' heart, blood glucose and insulin were measured and using HOMA score insulin resistance was measured. To be normal data distribution, Kolmogorov-Smirnov test was done and data analyzed by SPSS-20 software and ANOVA and post hoc Tukey tests. Results: The results showed that in the group receiving the cinnamon extract, glycemic and insulin indexes were significantly adjusted. Conclusion: Cinnamon is probably due to have flavonoid and antioxidant compounds with antioxidant by increasing glucose uptake via the different body cells and due to reduction of oxidative stress level led to adjust glycemic and insulin indexes of blood

Abstract
Background: Ibuprofen is a nonsteroidal anti-inflammatory medication of drugs that is used for relieving pain. However, this drug has proven effects, such as the production of free radicals and interfering with cellular events. Thus, it is necessary to find suitable antioxidants to reduce the side effects of this drug. In this study the antioxidant effects of cinnamon extract on the inhibition induced hepatoxicity of ibuprofen has been investigated.
Materials and Methods: 48 rats in six groups, S group received saline solution, C200 group received cinnamon extract 200mg per kg body weight (200mg/kg b.w), I group ibuprofen 400mg/kg b.w, IC50 group ibuprofen together with cinnamon extract 50mg/kg b.w, IC100 group ibuprofen together with cinnamon extract 100mg/kg b.w, IC200 group ibuprofen together with cinnamon extract 200mg/kg b.w intraperitoneally. The activity of liver enzymes were measured in the end of the experimental period. Liver tissue sample was prepared and after staining with hematoxylin-eosin, was studied.
Results: The activity of Pyruvate transaminase, oxaloacetate transaminase and alkaline phosphatase in I group in comparison with S group were significantly increased. The activity of these enzymes in IC50, IC100 and IC200 groups in comparison with I group were significantly decreased nearly in a dose dependent manner. Examining the liver tissue indicate tissue damage caused by ibuprofen, and cinnamon consumption was reduced tissue destruction.
Conclusion: Cinnamon extract has antioxidant properties and reduces the ibuprofen induced hepatoxicity.

Abstract
Background: Diabetes may be associated with an imbalance between the protective effects of antioxidants and increased production of free radicals. Oxidative stress also appears to contribute to the pathogenesis of diabetic complications. In this study the effect of endurance exercise with cinnamon bark extract on antioxidant activity levels and cardiac index in streptozotocin- (STZ) induced DM in male rats were investigated.
Materials and Methods: In this experimental study, 50 male Wistar rats weight: 200-232 g were randomly divided into 5 groups (n=10): 1. Healthy control (CO), 2. Diabetic control (CD), 3. Diabetic + cinnamon extract treatment (D+CZ), 4. Diabetic + exercise training (D+EX), 5. Diabetic + cinnamon extract treatment + exercise training (D+EX+CZ). In D+EX+CZ group, the animals practiced endurance training for 8 weeks after becoming diabetic, and at the same times each rat has received 200 mg/kg cinnamon hydro alcoholic extract by gavage daily for 8 weeks.
Results: Exercise training in D+EX and D+EX+CZ significantly prevented the decrease in heart weight compared to DC and D+CZ groups. The activity of the antioxidant enzyme (catalase) in the D+EX+CZ group increased significantly compared to the control group. Superoxide dismutase also increased significantly in all groups compared to the control group. Also, the activity of GPX enzyme (glutathione peroxidase) in D+EX+CZ and D+CZ groups showed a significant increase compared to the control group.
Conclusion: The increased GPX, CAT and SOD activity and prevented the decrease in heart weight induced by combined intervention of cinnamon extract and endurance training may attenuate oxidative stress in diabetic rats
