Erythropoietin (EPO) regulates proliferation and differentiation of erythroid precursor cells into erythrocytes. The last decade has revealed non-renal sites of EPO production and extrahematopoietic expression of the EPO receptor, thus suggesting that EPO has pleiotropic functions. Here, we addressed the interplay between EPO/glucose metabolism/body weight by employing a panel of relevant experimental murine models. The models focused on situations of increased EPO levels, including EPO-injected C57BL/6 and BALB/c mice, as well as transgenic mice (tg6) constitutively overexpressing human EPO, thus exposed to constantly high EPO serum levels. As experimental models for diabetes and obesity, we employed protein Tyr phosphatase 1B (PTP1B) knockout mice associated with resistance to diabetes (PTP1B−/−), and ob/ob mice susceptible to diabetes and obesity. The data presented herein demonstrate EPO-mediated decrease in blood glucose levels in all mice models tested. Moreover, in the ob/ob mice, we observed EPO-mediated attenuation of body weight gain and reduction of hemoglobin A1c. Taken together, our data bear significant clinical implications of EPO treatment in the management of a wide range of metabolic diseases, thus adding an important novel therapeutic potential to this pleiotropic hormone.

Abstract Abstract 4557 Erythropoietin (EPO) regulates proliferation and differentiation of erythroid precursor cells into erythrocytes. The last decade has revealed non-renal sites of EPO production and extrahematopoietic expression of the EPO-receptor (EPO-R), suggesting that EPO has pleiotropic functions. We have previously shown anti-cancer and immunomodulating effects of the hormone in humans and mice. Here we addressed the interplay among EPO, glucose metabolism, and body weight by employing a panel of relevant experimental murine models. The models focused on situations of increased EPO levels, including EPO-injected C57BL/6 and BALB/c mice, as well as transgenic mice (tg6) constitutively overexpressing human EPO and thus exposed to constantly high EPO serum levels. As experimental models for diabetes and obesity we employed protein Tyr phosphatase 1B (PTP1B) knockout mice associated with resistance to diabetes (PTP1B-/-), and ob/ob mice susceptible to diabetes and obesity. Our data demonstrated an EPO-associated decrease in blood glucose levels in all mice models tested. The tg6 mice, continuously exposed to EPO, were hypoglycemic even under non-fasting conditions. Blood glucose reduction in the experimental models tested was evident already one week following EPO administration in all models, including the PTP1B-/- and ob/ob mice. This conclusion gained further support by the glucose tolerence test (GTT). EPO overexpression or administration led to improved glucose clearance in all the tested murine models. Notably, in the ob/ob mice we observed EPO-associated attenuation of body weight gain and reduction of hemoglobin A1C. Preliminary clinical observations with several diabetic patients support these data and will be discussed further. Taken together our data bear significant clinical implications for EPO treatment in the management of a wide range of metabolic diseases and add an important novel therapeutic potential to this pleiotropic hormone.

Aims: Arganimide A (4,4-dihydroxy-3,3-imino-di-benzoic acid) is a compound belonging to a family of aminophenolics found in fruit of Argania spinosa. The purpose of this study was to investigate the glucose and lipid lowering activity of Arganimide A (ARG A). Methods: The effect of a single dose and daily oral administration of Arganimide A (ARG A) on blood glucose levels and plasma lipid profile was tested in normal and streptozotocin (STZ) diabetic rats at a dose of 2 mg/kg body weight. Results: Single oral administration of ARG A reduced blood glucose levels from 26.50±0.61 mmol/L to 14.27±0.73 mmol/L (p<0.0001) six hours after administration in STZ diabetic rats. Furthermore, blood glucose levels were decreased from 5.35±0.30 mmol/L to 3.57±0.17 mmol/L (p<0.0001) and from 26.50±0.61 mmol/L to 3.67±0.29 mmol/L (p<0.0001) in normal and STZ diabetic rats, respectively, after seven days of treatment. Moreover, no significant changes in body weight in normal and STZ rats were shown. According to the lipid profile, the plasma triglycerides levels were decreased significantly in diabetic rats after seven days of ARG treatment (p<0.05). Moreover, seven days of ARG A treatment decreased significantly the plasma cholesterol concentrations (p<0.001). Conclusion: ARG A possesses glucose and lipid-lowering activity in diabetic rats and this natural compound may be beneficial in the treatment of diabetes.

Abstract Background Ethnobotany knowledge in a community has shaped local wisdom in utilizing plants to treat diseases, such as the use of Malaka (Phyllanthus emblica) flesh to treat type 2 diabetes. This study presented evidence that the phenolic extract of the Malaka flesh could reduce blood sugar levels in the diabetic induced rats. Methods The phenolic extract of the P. emblica was administrated to the glucose-induced rats of the Wistar strain Rattus norvegicus for 14 days of treatment where the Metformin was used as a positive control. The data generated were analyzed by the two-way ANOVA Software related to the blood glucose level and by SAS Software related to the histopathological studies at a significant 95% confidence. Results The phenolic extract with concentrations of 100 and 200 mg/kg body weight could reduce blood glucose levels in diabetic rats. The post hoc Dunnet test showed that the administration of the extract to the rats with a concentration of 100 mg/kg body weight demonstrated a very significant decrease in blood glucose levels and repaired damaged cells better than administering the extract at a concentration of 200 mg/kg weight body. Conclusion The evidence indicated that the phenolic extract of the Malaka flesh can be utilized as anti type 2 Diabetes mellitus without damaging other organs.

In recent years, many authors have investigated the possible antidiabetic effect of lactic acid bacteria. Lactobacillus species constitute a major part of the lactic acid bacteria group and have been found to exhibit beneficial effects on the development of diabetes and its complications. In the current study, we investigated the effects of newly characterised Bulgarian Lactobacillus strains, Lactobacillus brevis 15 and Lactobacillus plantarum 13, on blood glucose levels and body weight of rats fed a fructose-enriched diet. An experiment was conducted over a period of 8 weeks with 24 2-month-old Wistar rats randomly assigned to receive a standard diet (Con, control group), fructose-enriched diet (Fr group), standard diet with probiotics given twice a week (Pro group), and fructose-enriched diet with probiotics given twice a week (Pro+Fr group). At the end of the experimental period, a statistically significant increase in body weight was observed in all experimental groups (P<0.0001). The highest rise was seen in the fructose group (Fr, 169±19 g), followed by the Pro+Fr group (153±15 g), Pro group (149±13 g), and Con group (141±5 g). Moreover, the final blood glucose levels had risen significantly in the groups receiving fructose either without (Fr; P<0.0001) or with lactobacilli (Pro+Fr; P=0.002), while the rise was insignificant in the group of rats given probiotic supplementation only (Pro, P=0.071) and inexistent in the Con group (P=0.999). The highest elevation of blood glucose levels was observed in the Fr group (3.18 mmol/l), followed by the Pro+Fr group (2.00 mmol/l) whereas the Pro group showed the lowest levels (0.60 mmol/l). The results of our study suggest that the newly characterised Bulgarian Lactobacillus strains, L. brevis 15 and L. plantarum 13, could be considered as possible probiotics and might be able to prevent some metabolic disturbances.

Objective: The concept of the synergistic effect of poly-herbalism was as old as medicine history. Present novel polyherbal formulation (PHF) composed of five different herbs. The present investigation aimed to evaluate the synergistic therapeutic hypoglycemic potential of PHF against streptozotocin (STZ) (60 mg/kg b.w, ip)-induced diabetic rats. Methods: For this therapeutic study, the dose was framed orally once a day to the test objects after STZ dosing at 500 mg/kg/5 ml dosage levels for 21 days. The transformation of body weight and blood glucose level was examined, and the histopathological changes of beta cells of the pancreas, cellular architectures of liver and kidney were also perceived after scarification of the objects. Results: The outcomes were compared to that of glibenclamide (5 mg/kg) treated group. Declines of body weight and blood glucose levels were perceived in STZ-induced diabetic animals very significantly (p<0.01 or p<0.05). However, these diabetic changes were significantly (p<0.01 or p<0.05) decreased in PHF-dosing groups revealed more encouraging effects compared to that of glibenclamide. In the other hand, various liver function and enzymes test (creatinine, urea, total bilirubin, total albumin, alkaline phosphatase, gamma-glutamyl transferase, aspartate transaminases, and alanine transaminases) and lipid profile (total cholesterol, triglycerides, high-density lipoprotein cholesterol, total protein, low-density lipoprotein [LDL], and very LDL) studies strongly indicate the potential action of this novel formulation. Conclusions: It is deliberated that PHF has the favorable effect to normalize the blood glucose levels, and also rejuvenation and reproduction of beta cells lead a better futuristic ant diabetic therapy for diabetic management.

The carbon dioxide production of both 70-kg and 20-kg pigs in the 24-hour period following a subcutaneous injection of 0.125 mg of epinephrine in oil per kilogram of body weight was 7% and 11% higher, respectively, than that of the same pigs following a placebo injection. After 1 week of daily injections no significant response could be elicited by further epinephrine injections. Levels of blood and urine sugar rose to considerably higher levels after a first injection of epinephrine than after an eighth injection. It was concluded that pigs are able to develop a significant tolerance to the calorigenic effect of epinephrine.
