Objective: This study aimed to evaluate the effect of TFR2 on iron storage in type 2 diabetes. Methods: A cross-sectional study was conducted among 1,938 participants from the Jiangchuan Community of Shanghai. A total of 784 participants with T2DM and 1,154 normal participants (non-T2DM) were enrolled in this study. Serum ferritin, fasting blood glucose (FBG), postprandial blood glucose (PBG), and HbA1C levels were determined. Eighteen Wistar male rats were randomly assigned into three groups (n=6/group): rats in a high-fat diet streptozotocin (HFD+STZ) group were fed with high-fat diet for 4 weeks and intraperitoneally injected with streptozotocin (STZ); rats in a control group were fed with a standard diet for 4 weeks; rats in an STZ group were fed with a standard diet for 4 weeks and intraperitoneally injected with streptozotocin. Glucose tolerance test (GTT) was performed at the end of the study. Blood samples and liver tissues were assessed for liver TFR2, blood glucose, serum ferritin and iron levels. Results: The mean serum ferritin level of T2DM participants was significantly higher than that of the control group. (227 [140 – 352] vs. 203.5 [130.5 – 312], ng/mL, P < 0.05). Serum ferritin level was an independent risk factor for T2DM (high ferritin group vs. low ferritin group, 1.304 [1.03-1.651], P < 0.05). Diabetic rats showed reduced liver TFR2 levels, with increased serum ferritin levels. Conclusion: T2DM participants exhibited iron disorder with elevated serum ferritin levels. Elevated serum ferritin levels in diabetic rats were accompanied by reduced liver TFR2 levels.

Background: Serum ferritin levels reflecting the body iron stores, is known to be elevated in type 2 Diabetes Mellitus. However its association with diabetic complications including Diabetic nephropathy (DN), and overall glycemic control needs to be validated. Aims and Objectives: The aim of this study was to find the Serum Ferritin level abnormalities in DM patients with nephropathy in comparison with DM patients without nephropathy and to find correlation of Serum Ferritin (SF) levels with levels of Glycated Hemoglobin (HbA1c) in patients with diabetic nephropathy. Materials and Methods: This is a retrospective study, which included eighty five registered patients with Type 2 DM (44 Type II DM without nephropathy cases and 41 cases of Type II DM with nephropathy). SF and HbA1c was estimated in all cases across both the groups and were compared with age and sex matched controls and analysed. Results: Serum Ferritin levels were higher in diabetics with nephropathy compared to diabetics without nephropathy (p<0.0001). SF levels were higher in diabetic groups compared to control group (p <0.001).The correlation between HbA1c and SF was assessed among all cases of DM with nephropathy group using pearson correlation test and it showed a significantly positive correlation (r=0.431) with a SF (mean = 938±148) and HbA1c (mean = 9.2±2.02). Conclusion: Serum ferritin levels positively correlate with HbA1c levels in Type II DM cases with nephropathy, which suggests that serum Ferritin levels can be used as a surrogate marker of glycemic control in Type II DM with nephropathy.

Antidiabetic Effects

Objective: India is the “diabetes capital of the world” with 62.4 million Indians having type 2 diabetes in 2011. A major risk factor for insulin resistance is obesity, which is generally caused by regular physical inactivity and high-fat diet (HFD). Obesity and diabetes are closely related to each other as about 80% of diabetics are obese. Obesity is a common finding in type 2 diabetes. The objective of the study was to investigate the antidiabetic effects of [10]-gingerol in streptozotocin (STZ)- and HFD-induced diabetic rats. Methods: Wistar rats were used for the study. Animals were divided into six groups. The six groups in this study were, Group I (normal control), Group II (diabetic control), Group III (glibenclamide at 5 mg/kg p.o.), Group IV (orlistat at 60 mg/kg p.o.), Group V ([10]-gingerol at 15 mg/kg p.o.), and Group VI [10]-gingerol (30 mg/kg p.o.), respectively. The antidiabetic activity was assessed using blood glucose level, body weight, and various biochemical parameters such as serum total cholesterol (TC) level, triglyceride (TG) level, high-density lipoproteins (HDLs), total protein (TP), serum alanine transaminase, and aspartate aminotransferase (serum glutamic-oxaloacetic transaminase), respectively. Results: [10]-gingerol exhibited an antidiabetic effect by significantly decreased the level of blood glucose, body weight, TC, TG, TP, and increase HDL. The results of the study demonstrated that the treatment with [10]-gingerol significantly (p<0.05) and dose dependently prevented STZ- and HFD-induced diabetic rats. Conclusions: The findings of the study suggest that [10]-gingerol possesses potential antidiabetic activity as it lowers serum glucose level.

At present, the serum ferritin level is not included in the list of prognostic factors; however, it is known that its increased serum level in patients with malignant neoplasms relates with the tumor burden, the degree of disease activity and correlates with a worse prognosis in patients with hematologic malignancies.The normalization of serum ferritin level during remission period confirms the involving of hyperferritinemia in mechanisms of tumor progression and may testify for clinical importance of measurement of serum ferritin level in patients, including those with malignant lymphomas. Objective:The aim of this study was to assess of the prognostic significance of high ferritin levels at the onset of the disease in patients with malignant lymphomas. Materials and methods:98 patients with malignant lymphomaswere enrolled in this study, including 72 patients (73.5%) with non-Hodgkins lymphomas (NHL) and 26 patients (26.5%) with Hodgkin’s lymphoma (HL). The increased serum ferritin level (more than 350 ng/ml) was found in 53 (54.2%) patients with malignant lymphomas at the onset of disease and its average concentration was 587,62±131,6 ng/ml (8.3 times higher values of control group, p<0.001).Also the positive statistical correlationsbetween increased ferritin level and increased level of LDH (r=0.47, p<0.001, n=98) and C-reactive protein (r=0.41, p<0.001, n=98) as well as the presence of B-symptomswere found. The median OS was significantly shorter in the group of patients with increased ferritin level (more than 350 ng/ml) at the onset of disease in comparison with group of patients with normal ferritin level, where the median OS was not reach during the observation period. Patients with increased ferritin level before starting chemotherapy also showed worse results of overall survival and increased mortality risk (OR 8.122; 95% CI, 1.764-37.396;р<0.05) compare with a group of patients with ferritin level ˂350 hg/ml at the onset of disease. Conclusion:These results make it possible to include lymphomas’s patients with increased ferritin level at the onset of disease in the group with poor prognosis and lower OS, while the increased ferritin level in patients without previous blood transfusions should be considered as a significant prognostic factor.

Background and Aims: In the current work, we studied the effects of exercise and stevia rebaudiana (R) extracts on diabetic cardiomyopathy (DCM) in type 2 diabetic rats and their possible underlying mechanisms. Methods: : Thirty-two male Sprague Dawley rats were randomly allocated into 4 equal groups; a) normal control group, b) DM group, type 2 diabetic rats received 2 ml oral saline daily for 4 weeks, c) DM+ Exercise, type 2 diabetic rats were treated with exercise for 4 weeks and d) DM+ stevia R extracts: type 2 diabetic rats received methanolic stevia R extracts. By the end of the experiment, serum blood glucose, HOMA-IR, insulin and cardiac enzymes (LDH, CK-MB), cardiac histopathology, oxidative stress markers (MDA, GSH and CAT), myocardial fibrosis by Masson trichrome, the expression of p53, caspase-3, α-SMA and tyrosine hydroxylase (TH) by immunostaining in myocardial tissues were measured. Results: T2DM caused a significant increase in blood glucose, HOMA-IR index, serum CK-MB and LDH, myocardial damage and fibrosis, myocardial MDA, myocardial α-SMA, p53, caspase-3, Nrf2 and TH density with a significant decrease in serum insulin and myocardial GSH and CAT (p< 0.05). On the other hand, treatment with either exercise or stevia R extracts significantly improved all studied parameters (p< 0.05). Moreover, the effects of stevia R was more significant than exercise (p< 0.05). Conclusion: Both exercise and methanolic stevia R extracts showed cardioprotective effects against DCM and Stevia R offered more cardioprotective than exercise. This cardioprotective effect of these lines of treatment might be due to attenuation of oxidative stress, apoptosis, sympathetic nerve density and fibrosis and upregulation of the antioxidant transcription factor, Nrf2.

AIM: This work was done to study the effect of both types of diabetes mellitus (DM) on myocardial contractility in rats. Also, we investigated the role of treatment of DM with insulin and rosiglitazone (used as treatment for type 1 and type 2 DM respectively) in improvement of myocardial dysfunction in diabetic rats.METHODS: The study included 50 male Wistar albino rats, divided into 5 groups: control (group I), streptozotocin induced type 1 DM (group II), fructose induced type 2 DM (group III), insulin treated type 1 diabetic rats (group IV) and rosiglitazone treated type 2 diabetic rats (group V). At the end of the study, retro-orbital blood samples were withdrawn and blood glucose, plasma triglyceride (TG), total cholesterol (TC) and thyroid hormones levels were measured. Rats were then anesthetized and their hearts were excised and connected to Langendorff apparatus to perform mechanical cardiac performance tests including heart rate (HR), left ventricular developed pressure (LVDP) and maximum rate of pressure rise (+dp/dt).RESULTS: Data of the study showed that relative to control group, there was significant increase in blood glucose, plasma TG and TC levels while, thyroid hormones and myocardial performance parameters showed significant decrease in both type 1 and type 2 diabetic rats. Treatment of type 1 diabetic rats with insulin and type 2 with rosiglitazone resulted in significant decrease in blood glucose, plasma TG and TC levels associated with significant improvement in thyroid hormones and myocardial performance parameters. The results also showed that insulin treatment of type 1 was more effective in ameliorating all parameters than treatment of type 2 by rosiglitazone.CONCLUSION: We concluded that the induction of both types of diabetes resulted in decreased myocardial performance parameters. The  treatment of type 1 and type 2 diabetes by insulin and oral rosiglitazone respectively improved to a great extent the altered metabolism and  mechanical myocardial parameters, with more improving effect of  insulin in type 1 than rosiglitazone in type 2 DM.

The experimental animal study was undertaken to investigate the preventive role ginger juice against hyperglycemia in alloxan induced diabetic rats.Male wistar rats,(130-150)gm wt fed on standard diet and water ad libitum, were divided into 3 groups(n=6) in each group: Group-L non-diabetic control group, Group-II, diabetic control & Group-III, normal rats pretreated with ginger before they were made diabetics. Diabetes was induced by inj. alloxan 150mg/kg body wt.,tp (Group-IL on 2nd day & Group-Ill, on the 9th day).Rats having blood glucose level of more than 7mmol/L on day 5(72 hours after alloxan inj) were considered diabetic & selected for experiment. Rats of Group-Ill received Zingiber officinale (ginger juice) (4m1/kg.body,wt orally) for 7 days (day 2-day8) through Pyles tube before alloxan induction & 3days after the induction. On day 12, animals were sacrificed under light ether anaesthesia, blood was collected by cardiac puncture for blood glucose estimation. Pretreatment with Zingiber officinale (ginger) juice significantly (p<0.01) reduced alloxan induced hyperglycemia.Zingiber officinale (ginger) is one of the most widely used spices and is reputed to have medicinal properties against diabetes mellitus. This study suggests that pretreatment with Zingiber officinale(ginger) prevents the development of hyperglycemia in alloxan induced diabetic rats.

INTRODUCTION: Type 2 diabetes mellitus is a metabolic disorder of multiple etiology characterized by chronic hyperglycemia with a derangement in carbohydrate, fat and protein metabolism resulting from defects in insulin secretion and action. Ferritin is a ubiquitous intracellular protein complex that reflects the iron stores of the body. Studies have shown that the increased body iron stores are associated with the development of glucose intolerance often leading to metabolic syndrome and type 2 diabetes (T2DM). The objective of the study was to find out association of serum ferritin level with T2DM and assess the correlation between serum ferritin and HbA1c. MATERIAL AND METHODS: A hospital based comparative cross-sectional study was conducted in 43 diabetic patients and 42 age and sex matched healthy controls. Fasting blood glucose (FBG), postprandial blood glucose (PBG), Glycated hemoglobin (HbA1c) and serum ferritin were estimated in cobas c311 autoanalyser using standard protocol. RESULTS: Mean age of healthy control and T2DM were found 54.83 ± 6.48 and 55.95±10.92 years respectively. Mean FBG (mg/dL) (170.41 ± 71.7 v/s 98.38 ± 9.7), PBG (mg/dL) (266.16 ± 110.09 v/s 123.20 ± 17.0), HbA1c (%) (8.17 ± 1.83 v/s 4.9 ± 0.29 and median ferritin (μg/L) 207.90 (138, 306.0) v/s 127.95 (85.75, 210.25) were significantly higher in T2DM compared to the healthy controls. Spearman’s correlation depicted that ferritin level was positively correlated with HbA1c level but the correlation was statistically insignificant. CONCLUSION: Serum ferritin level was found significantly higher in T2DM compared to healthy age and sex matched controls in our study.
