Abstract
Background: Alloxan is on of the xenobiotic agents which is classified as diabetogenic materials. Magnesium is an important cofactor regulating the activity of carbohydrate enzymes and lipid synthesis. In this study the contrasting effects of Alloxan and magnesium on plasma free fatty acids (FFA) in rats was investigated.
Methods: Male mature rats were used as test models for the diabetes induction. 28 rats received Alloxan (120mg/kg) intraperitoneally and plasma glucose level measurement after 72 hours demonstrated diabetes induction.
Results: The results were compared to the control groups, and confirmed the presence of diabetes in rats. Analysis of plasma FFA showed a significant increase (751.25 mM), compared to the control group (286.68 mM). In contrast, Measurement of red blood cell (RBC) Magnesium showed a significant decrease from 7.18 mg/dL in control group to 4.89 mg/dL in diabetic rats.
Conclusion: The results of this study showed that in diabetic condition, there was an inverse relationship between plasma FFA and RBC Magnesium. Therefore, these data suggest that analysis of the effects of Magnesium upon induction of diabetic condition could provide important information for management of diabetes.

Abstract
Background: Artichoke with the scientific name of Cynara scolymuse is a plant from compositae family. In this research, the effect of hydro alcoholic artichoke extract on serum glucose, lipids and lipoproteins and prevention of type 1 diabetes mellitus was investigated.
Methods: Twenty mature male Rats with mean weight of 200-250 gr in four groups were arranged. Rats in the control group, received physiological serum. The Second group (diabetic) received 120 mg/kgbw Alloxan monohydrate. The Third group (diabetic + Glibenclamide) received 0.5 mg/kgbw Glibenclamide in addition of the similar treatment with second group. The Fourth group (Alloxan monohydrate + Cynara scolymus), received 120 mg/kgbw Alloxan monohydrate with 300 mg/kgbw of Cynara scolymus simultaneously. Prescribing materials in all groups was done as interaperitoneal injection(IP). Fourty eight hours after last IP, blood sample was taken from each animal via cardiac puncture to measure blood factors.
Results: The results indicated significant reduction in glucose, cholesterol, triglyceride, VLDL and LDL levels in the treated group with extract and Alloxan monohydrate simultaneously as to compared diabetic group. Also, the result indicated significant increase in HDL level. Hydroalcoholic Artichoke extract could not reduce blood glucose level as compared with Glibenclamide, but had similar effects on other factors in comparison with Glibenclomide.
Conclusion: Artichoke contains antioxidants compounds, that plays a protective role on beta cells against Alloxan. The results of this research indicate that hydro alcoholic extract of Cynara scolymus could effectively prevent type 1 diabetes mellitus.

Background: plants have been used in treatment of diabetes mellitus (DM) all over the world for centuries. Studies have indicated that, numerous classes of chemical compounds found in plants are potential effective in the treatment of diabetes. Lemon balm (Melissa officinal is) is a member of Lamiaceae family. In this study, were studied the effect of Melissa officinal is hydroalcoholic extracts in the prevention of diabetes and its effect on serum lipids and lipoproteins in rats.
Methods: Inthisstudy25male rats, weighing200-250grams were semi-randomly divided into5groups of 5 each. Group1(control),group2(diabetic),and groups3, 4and5, respectively extract with doses20, 100and500 mg/Kg/BW, for a period of two weeks every day through were gavaged and then diabetes was induced by way of intra peritoneal injection of alloxan at a dose120mg/kg WB .Blood from rats was performed in order to measure the serum concentrations of glucose, cholesterol, triglycerides, HDL and LDL.
Results: The results indicated a significant decrease (P<./.5) in levels of blood sugar, cholesterol, triglycerides and LDL in rats treated with the extract of Melissa officinal is. In addition, significant increase (P<./.5) in HDL level were observed in treating rats in comparison to the diabetic group.
Conclusion: The results of this study indicated that the Melissa officinal llis extract may be used effectively in preventing, controlling and attenuating the complications of DM. This effect can be due to the presence of flavono ides and their antioxidant features in these plant.

Abstract
Background: Diabetes is one of the most common diseases of the body's endocrine system, Based on present forecasts of its prevalence will increase in human societies. Diabetes mellitus consists of 5 groups, its two major groups: type I diabetes or insulin-dependent and type II diabetes or non-insulin dependent diabetes. The aim of this study was to evaluate the effect of alcoholic extract of green wheat leaves on glucose, cholesterol, triglycerides, LDL, HDL and total antioxidant capacity of blood serum in alloxan-induced diabetic mice.
Methods: In this study, 40 male mice with an average weight of 25-20 grams in eight groups of five rats: The negative control, positive control (sham), Methformin (60mg/kg), green Wheat leaf extract (100, 200, 400, 800 and 1000mg/kg) were tested. Blood glucose was measured at baseline, then in the positive control group and the experimental groups by Alloxan (120mg/kg) Diabetes was induced by intraperitoneally. During the study, the positive control group and experimental groups received aforementioned compounds for 10 days via intraperitoneally and after 48 hours of each group blood samples were taken through the intraventricular anesthesia and glucose, cholesterol, triglycerides, LDL, HDL and total antioxidant capacity in serum were measured. Quantitative results achieved in this research by one-way ANOVA and Tukey post hoc test between the groups studied Considering the significance level of p <% 5 were analyzed.
Results: The results showed that blood glucose changes in green Wheat leaf extract and metformin groups compared with the positive control group and negative control group was significant at the 5% level and In all under study groups blood glucose levels, Compared with the positive control group decreased and is close to the negative control group also in doses of 100, 200, 800 and 1000 mg/kg Reduced blood glucose is better than methformin group. Methformin and green Wheat leaf extract caused a significant increase at all doses studied in the TAC's Blood. Methformin and green Wheat leaf extract on the amounts of LDL, HDL and cholesterol in diabetic groups had no significant effect and did not have significant difference with other groups. There was no significant effect of different doses of green Wheat leaf extract on the blood triglycerides. However, metformin has a significant impact on triglyceride levels.
Conclusion: The results of the effects of green Wheat leaf extract on glucose and serum antioxidant capacity
It can be noted that these extracts in the treatment of diabetes and reduce its complications can be considered as an option.

Abstract
Background: Diabetes produces free radicals and damages the liver. The aim of this study was to investigate the effects of Rosmarinus Officinalis leaf hydroalcoholic extract on histopathology and enzymes activity of liver in alloxan induced diabetic rats.
Methods: In this study, 50 adult male Wistar rats weighing 200 to 250 grams, were divided randomly into 5 groups of 10; non-diabetic control, diabetic control and 3 experimental groups (diabetic rats treated with the dosage of 50mg/kg, 100mg/kg and 200mg/kg rosemary leaf extract intraperitoneally for 14 days).
Diabetes was induced in rats by intraperitoneal injection of a single dose 120 mg/kg alloxan was done. At the end of the treatment period, blood samples were taken from the left ventricular heart of mice and aspartate aminotransferase (AST / SGOT), alanine aminotransferase (ALT / SGPT) and alkaline phosphatase (ALP) in serum were measured. Immediately liver was removed and histological samples were fixed in 10% formalin and then stained with hematoxylin-eosin technique (H & E).
Results: In diabetic rats, unlike control mice, the liver enzymes (AST, ALT and ALP) increases, because of damage of liver tissue (p<0.01).
The level of liver enzymes (AST, ALT and ALP) in rats treated with doses 50mg/kg, 100mg/kg and 200mg/kg of rosemary leaf extract showed a significant reduction in these enzymes compared to control diabetes (p<0.01).
Conclusion: Histological studies showed reduced inflammation in the liver lobule and the port in the experimental groups. The third experimental group had greatest impact on reducing liver inflammation and space ports showed lobule. Histologically, tissue changes were in line with biochemical changes.
The effects of Rosmarinus Officinalis leaf hydroalcoholic extract because of its high antioxidant properties, reduce free radicals and inflammation of the liver damage caused by diabetes by inhibiting the enzyme is reduced.

Abstract
Background: Despite advances in diabetes-related treatments, the effects of the disease have not yet been adequately reversed or prevented in patients.
Methods: In this study, type 1 diabetes mice models was established using multiple low-dose alloxan, and the diabetic mice were treated with three doses of dimethyl fumarate (DMF) i.e low, medium, and high viz. 20, 40 and 80 mg/kg, respectively for a period of 21 days. Then, specific test were done to evaluate blood biochemical parameters, oxidative stress markers, inflammatory genes expression, and histopathological changes in the mice kidney and liver.
Findings: The obtained results showed remarkably improved anti-diabetic, hepato-renal-protective, and oxidative stress indexes of DMF in alloxan-induced diabetic mice (p< 0.001). Treated mice with DMF demonstrated a noteworthy decrease in blood glucose levels when compared with diabetic group (p< 0.001). On the contrary, the histological features of the treated mice with DMF improve as shown by normal size of glomerular capillaries along with decrease in less dilatation of ducts in comparison with diabetic mice. The real-time quantitative PCR results indicated that DMF injection decreased the alloxan-induced increase of significant elevations in mRNA levels of pro-inflammatory cytokines levels in both kidney and liver tissues. Meanwhile, mice treated with DMF showed an increase in Sirt1 and Nrf2 expression in comparison to diabetic group.
Conclusion: In conclusion, it can be concluded that DMF treatment provides hepato-renal protective effects on alloxan-induced diabetic mice model by attenuating ROS inflammatory pathways.
