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 : Women with polycystic overy syndrome (PCOS) are sussceptible for developing type 2 diabetes (T2DM) and cardiovascular diseases. In view increased prevalence of T2DM in patients with PCOS and priority of prescription agents capable to decrease insulin resistances for them, It is important to diagnose PCOS in T2DM patients. The aim of this study was to evaluate the prevalence of PCOS in T2DM women.
Methods : Using ‘1990 National Institute of Child Health and Human Development Conference of PCOS’ criteria, 157 premenopausal women with T2DM were assigned into PCOS and non – PCOS groups after they were examined for the evidences of clinical PCOS. A questionnaire on reproductive history was completed and the waist circumference, weight, height and BP were measured for each participant. Biochemical tests were performed in both groups, but hormonal measurements were requested only for PCOS group.
Results : The prevalence of PCOS was high (about 8%) among subjects. Patients with PCOS had significantly lower age at the onset of diabetes, higher BMI and waist circumference. The differences in BP, serum TG, HDL, LDL, cholesterol and HbA1c were non – significant between 2 groups and insulin resistance is more.
Conclusion : PCOS is prevalent in diabetic women and Insulin resistance is more likely in those with both PCOS and T2DM resistant than whom with diabetes alone. Emphasis on reducing insulin resistance may be of benefit to achieve a better diabetes control in these patients.
