Background and Aim: In this study rats, a systematic analysis was conducted to examine the antioxidant
properties of cinnamon (Cinnamomum Zeylanicum, Breyne) in controlling high blood sugar levels, and a
pharmacological comparison made to investigate whether or not it had a positive effect on the antioxidant
Materials and Methods: Alloxan 60 mg injected into the marginal ear veins of eighteen diabetic rats After
this diabetic animal study, the rats were randomly assigned to 4 groups. There were six animals in each of
the 4 groups: Group 1(C): Positive control, Received orally 5 ml normal saline (0.9% NaCl) daily. Group
2(D): Negative control, Diabetes rats only, received single-dose alloxan 60 mg/kg body weight. Group
3(K): Diabetes rats, received cinnamon orally 35 mg/kg body weight dissolved in 2 ml normal. Group 4(I):
Diabetes rats, was given 2 I.U/ animal of insulin subcutaneously daily.
Results: All animal groups were treated for four weeks.Blood samples were taken from these groups weekly
for biochemical analysis to estimate: Blood glucose malondialdehyde(MDA), Glutathione (GSH). The
results showed high glucose and MDA concentration associated with an increased oxidant stress alloxan
induces on diabetic animals. The statistical analysis showed that a cinnamon significant (P<0.05) reduction
in glucose, MDA,GSH comparison with positive control. The level of MDA, GSH was also significantly
reduced (P<0.05) in all period comparison with the period before treated with Cinnamon extract .there was
4.3-fold more Ins I upregulated in the Cinnamon -treated diabetic rats 35 percent of the control group were
heterozygous and three percent of the experimental group were mutant for that trait.
Conclusion: Furthermore, Cinnamon-treated diabetic rats (group K) showed a significant increase in
the activities of both enzymatic and non-enzymatic antioxidants with concomitant overexpression of
insulin I genes when compared to diabetic control rats (group D). Cinnamon contains antioxidants and
antihyperglycemic effects at the end of the experiment.
