Introduction: Generally in the world, diabetes is the most significant cause of deaths and morbidity. Blood glucose lowering agents possess remarkable adverse effects like weight gain and hypoglycemia and thus hindering the achievement of glycemic control. Since earliest times till today, herbal preparations have been utilized for management of diabetes and its complications. Aims & Objectives: To investigate antihyperglycemic and nephroprotective effects of Ajwa pit and pulp in alloxanized - diabetic and nephropathic rats. Place and duration of study: This study was conducted at Postgraduate Medical Institute, Lahore for the duration of four weeks. Material & Methods: Adult male rats (weighing 120-150 g), total of 32 were purchased and divided into 4 groups. The group1 was normal control whereas group2 was diabetic control. Diabetes was induced in groups 2, 3 and 4 with 150mg/kg single alloxan monohydrate1.P Injection. Groups 3 and 4 were given Ajwa pit and pulp rations for 4 weeks. Blood and urine samples were taken on zero and 4 weeks for fasting blood glucose, serum and urine biochemical variables for renal functions. Results: The results revealed that Ajwa pits significantly decreased serum levels of glucose (252±60 vs. 348±67 mg/dl), serum urea (38±7.0 vs. 63±9.6 mg/dl), serum creatinine (0.39±0.1 vs. 0.58±0.1 mg/dl) and microalbuminuria marker (7.8±1.7 vs. 9.0±2.2mg/l). Moreover it improved urine creatinine (14.0±2.9 vs.10.0±2.7 mg/dl) and creatinine clearance (0.226±0.08 vs 0.117±0.04 ml/min) when compared to diabetic control rats. Effect of Ajwa pulp was far less than Ajwa pit. Ajwa pulp did not significantly decrease serum levels of glucose (290±60 vs. 348±67 mg/dl), urea (51±9.5 vs. 63±9.6 mg/dl), creatinine (0.66±0.2 vs. 0.58±0.1 mg/dl) and microalbuminuria marker (8.3±2.0 vs. 9.0±2.2mg/l). Also there was no improvement in urine creatinine (11.1±1.6 vs. 10.0±2.7 mg/dl) and creatinine clearance (0.130±0.05 vs 0.117±0.04 ml/min) levels when compared to diabetic control rats. Conclusion: Ajwa pit possesses strong antihyperglycemic and protective effect in renal damage by prolonged diabetes mellitus. Highest polyphenols, bioflavonoids and antioxidants are presumed to be responsible for this effect.

Purpose: To investigate the effect of Polygonatum sibiricum extract (PSE) on streptozotocin-induced diabetic rats. Methods: PSE was obtained by steeping the dried Polygonatum sibiricum in water at 60 oC three times, each for 1 h, before first drying in an oven at 100C and then freeze-drying the final extract, thus obtained. Diabetic model rats were prepared by a single intraperitoneal injection of a freshly prepared solution of streptozotocin (50 mg/kg). The rats were randomly divided into 6 groups of ten rats each: negative control, normal control, reference (glibenclamide1 mg/kg) as well as PSE groups, (35, 70 and 140 mg/kg). Blood glucose and plasma insulin levels were measured to determine antihyperglycemic effect. Oxidative stress was evaluated in liver and kidney by their antioxidant markers, viz, lipid peroxidation (LPO), superoxide dismutase (SOD), reduced glutathione (GSH), glutathione peroxidase (GPx) and catalase (CAT). Blood serum levels of creatinine and urea were determined in both diabetic control and treated rats. Results: Compared with diabetic rats, oral administration of PSE at a concentration of 120 mg/kg daily for 30 days showed a significant decrease in fasting blood glucose (118.34 ± 3.29 mg/dL) (p < 0.05) and increased insulin level (12.86± 0.62 uU/mL, p < 0.05). Furthermore, it significantly reduced biochemical parameters (serum creatinine, 0.83 ±0.21 mg/dL, p < 0.05) and serum urea (43.26±1.42 mg/dL, p < 0.05). Conclusion: The results suggest that PSE may effectively normalize impaired antioxidant status in streptozotocin-induced diabetes in a dose-dependent manner. Thus, PSE has a protective effect against lipid peroxidation by scavenging free radicals, restoration of insulin function, and reduction of the incidence of complications.

Purpose: To explore the antihyperglycemic and antioxidant effects of Fructus Hordei Germinatus extract (FHGE) in diabetic rats.Methods: The aqueous extract of FHG was obtained by steeping the dried Fructus Hordei Germinatus in water at 60oC three times, each for 1 h before first drying in an oven and then freeze-drying the last extract thus obtained. Antihyperglycemic effect was measured by blood glucose and plasma insulin levels. Oxidative stress was evaluated in liver and kidney by antioxidant markers, viz, lipid peroxidation (LPO), superoxide dismutase (SOD), reduced glutathione (GSH), glutathione peroxidase (GPx) and catalase (CAT), while blood serum levels of creatinine and urea were also determined in both diabetic control and treated rats.Results: Compared with diabetic rats, oral administration of FHGE at a concentration of 20, 40 and 80 mg/kg daily for 45 days showed a significant decrease in fasting blood glucose (p < 0.05) and increased insulin (p < 0.05) level,. Furthermore, it significantly reduced biochemical parameters (serum creatinine and serum urea, p < 0.05)). The treatment also resulted in significant increase in GSH, GPx (p < 0.05), SOD and CAT (p < 0.05), as well as decreased LPO (p < 0.05) level in the liver and kidney of diabetic rats.Conclusion: The results suggest that FHGE may effectively normalize the impaired antioxidant status in streptozotocin-induced diabetes in a dose-dependent manner. FHGE has a protective effect against lipid peroxidation by scavenging free radicals and is thus capable of reducing the risk of diabetic complications.Keywords: Fructus hordei Germinatus, Diabetic, Antihyperglycemic, Lipid peroxidation, Antioxidant, Fasting blood glucose, Creatinine, Urea

Abstract Background Sex hormone, adiponectin and its receptors interacted in the testes. Diabetes can also interfere with this interaction. Regular exercise has some effects on the diabetes side effects. This study purpose was to investigate the effects resistance and endurance training on adiponectin gene expression and its receptors and sex hormones in those rats with diabetes.MethodsIn this experimental study, 48 male Wistar rats were divided into 6 groups by random. After performing the trainings, adiponectin gene expression and its receptors in the testis were evaluated using real time PCR, and blood serum was then used in order to assess FSH, LH and testosterone.Results The induction of diabetes mellitus STZ-NA significantly increased the serum level of fasting blood glucose, the gene expression of adiponectin and also the AdipoR 1 in the testicles of diabetic rats in comparison with healthy controls. In addition, diabetes resulted in a significant reduction in serum testosterone levels and LH in diabetic group, but it has no effect on FSH.Conclusions Resistance and endurance training decreased the blood glucose with a significant amount reduction in adiponectin levels and AdipoR 1 gene rats, and also increased the serum testosterone levels and LH in diabetic rats. Resistance and endurance training can improve expression of adiponectin and AdipoR 1 gene by increasing the serum testosterone and LH levels in type 2 diabetic rats.

Characterised by abnormal increase in blood glucose level, Diabetes is a metabolic disorder that is associated with complications in carbohydrate, protein and fat metabolism. In recent times, medicinal herbs have been implicated in traditional medical practice for the treatment of this ailment. Studies have shown that Buchholzia coriacea seed possesses some anti-hyperglycemic properties that may be useful in the management of diabetes. To this point, present study investigated the effect(s) of oral administration of aqueous and ethanol extracts of Buchholzia coriacea on some carbohydrate metabolism parameters in normal and alloxan-induced diabetic rats. Forty (40) adult rats of both sexes were randomly assigned into two groups (normoglycemic and hyperglycemic). While group 1 (normoglycemic) had normal control, metformin, aqueous extract (250mg/kg) and ethanol extract (250 mg/kg) treated sub-groups respectively, Group 2 (hyperglycemic) contained the diabetic control, metformin, aqueous extract (250 mg/kg), and ethanol extracted (250mg/kg) treated sub-groups dosed daily by oral gavage for 14 days. At the end of the treatment, rats were euthanized via cervical dislocation; blood samples were collected by cardiac puncture for statistical analysis. One-way analysis of variance (ANOVA) revealed that dosing with extracts had insignificant effect(s) on body weight of rats. Fasting Blood Glucose (FBG) levels were elevated before and after extracts administration. Metformin, aqueous and ethanol extracts significantly reduced (p<0.05) FBG levels. Also, compared with control, total carbohydrate, liver glucose, glycosylated haemoglobin, Lactate Dehydrogenase, Isocitrate dehydrogenase, MDH, SDH, 6-phosphogluconate dehydrogenase, G6PD and CcO activities were significantly reduced (p<0.05) in diabetic treated rats. Buccholzia Coriacea was therefore seen to pose hypoglycemic and glycolytic effects, regulating activities of carbohydrate metabolic enzymes. Apparently, there is a scientific merit in the use of the extract in the management of diabetes.

Type 2 diabetes mellitus (T2DM) is one of the main non-communicable chronic diseases that has many complications that compromise the quality of life. Hence, the need to find alternatives to replace the current therapy or as an adjuvant. Tubers of Myrmecodia platytytrea (Rubiaceae) has been used traditionally as an alternative therapy for the management of cancer and other inflammatory-related disorders. The aim of this study was to investigate the potency of M. platytytrea methanolic tuber extract (MPMTE) as an antihyperglycemic agent, in vivo. :The streptozotocin (STZ)-induced diabetic rats were treated orally with MPMTE (100, 200 and 400 mg/kg) and metformin (positive control, 100 mg/kg) daily for 14 days. Blood glucose level and other biochemistry analysis were conducted including histological examination on liver, kidney and pancreas.  The STZ-induced diabetic rats treated with MPMTE (200 and 400 mg/kg) had significant decreased (p<0.05) in fasting blood glucose, total cholesterol, triglycerides and low-density lipoprotein (LDL) with no significant changes in high-density lipoprotein (HDL) compared to STZ-induced untreated diabetic rats. Liver, kidney and pancreas were devoid of any damage caused by STZ.  MPMTE had strong antihyperglycaemic activity and was protective against any STZ-induced organ damage. Thus, MPMTE can be further developed into an adjuvant therapy for diabetic patients.

Diabetes mellitus is an endocrine and metabolic disorder of humans and animals characterized by hyperglycemia and low blood insulin levels or insensitivity of target organs to insulin and it’s a major health problem affecting patient’s quality of life due to its many complications. Infertility is one of the major secondary complications in diabetes. Although numerous drugs have been used for intervention studies on diabetes-induced infertility worldwide, there are currently no treatments for diabetes associated infertility in humans. This study was performed to investigate the effects of Annona muricata ethanolic leaf extract (AMELE) on fertility of male diabetic rats and levels of blood glucose. Twenty male Wistar rats (150-200g) were randomly distributed into 4 groups (n=5) treated thus: CTRL (control), DNT, DT1 and DT2 (diabetic, single intraperitoneal injection, streptozotocin, 60 mg/kg). Group DT1 and DT2 received AMELE orally at 100 mg/kg and 200 mg/kg respectively daily for fourteen days. Data were analysed using ANOVA at α0.05. The animals were sacrificed after 2 weeks via thiopental injection and testicular weights were recorded. Fasting blood glucose was determined using a digital glucometer. Sperm count, motility, viability and morphology were assessed microscopically. Testes were histologically evaluated. The results showed that oral administration of AMELE at 100 mg/kg and 200 mg/kg to diabetic male rats for fourteen days significantly decreased blood glucose level and also ameliorated diabetes-induced decreases in sperm functions in streptozotocin-induced diabetic male rats.

Background: Preventive measures that could slow down the rising incidences of diabetes mellitus are essential. The use of neglected local foods, which have effects on this chronic disease beyond basic nutrition as dietary controls, is desirable.Objective: The effect of Dioscorea dumetorum (Kunth) Pax (Dioscoreaceae) feed on satiety, weight, blood glucose, and insulin levels were investigated in streptozotocin-induced diabetic rats.Methods: Twenty adult male rats in four groups of five were used for the experiment. Three groups – D. dumetorum, glibenclamide, and standard pellet-fed rats were induced with diabetes by i.p. administration of 50mg kg-1 streptozotocin, while the fouth group (?) served as a non-diabetic control. D. dumetorum was fed at 15g daily for ten days before induction, and after induction, feeding continued. Glibenclamide was orally administered 5mg kg-1 daily. Both the untreated and non-diabetic rats were kept on standard rat pellets. Feed intake, weight, and blood glucose concentration were monitored daily, while insulin level was measured on day two and day six after inductions. Results: Average feed intake for non-diabetic rats was 15g for D. dumetorum per day, which dropped to 10.3g after induction of diabetes. Weight of normal non-diabetic rats consistently increased (142.61 ± 4.37g – 169.43 ± 8.61g) for the duration (17 days) of the experiment. The D. dumetorum-fed rats showed weight reduction of 5.4%, glibenclamide 4.0%, and untreated diabetic 6.15%. Non-diabetic rats blood glucose levels ranged between 70 to 100mg dL-1. Streptozotocin (STZ) (i.p.) administration increased blood glucose levels from 370% to 626% in the rats. D. dumetorum-fed rats showed reduced (p<0.05) blood glucose levels of 22.6%. Glibenclamide had 5.5% reduction (p<0.05). Insulin was absent in D. dumetorum-fed rats, whereas 0.95ng ml-1 of insulin was detected in glibenclamide-administered rats. These quantities were lower (p<0.001) than 1.40ng ml-1 in the non-diabetic rats. Conclusion: This study revealed that D. dumetorum tuber caused decreased hunger, weight reduction, and displayed hypoglycemic property in diabetic rats, even after heat treatment. Its probable mechanism of anti-hyperglycemic activity might not be through increased insulin secretion.Key words: D. dumetorum, streptozotocin-induced diabetes, weight, blood glucose, insulin.

The effects of a polyherbal mixture containingAllium sativum,Cinnamomum zeylanicum,Citrullus colocynthis,Juglans regia,Nigella sativa,Olea europaea,Punica granatum,Salvia officinalis,Teucrium polium,Trigonella foenum,Urtica dioica, andVaccinium arctostaphyloswere tested on biochemical parameters in diabetic rats. The animals were randomized into three groups: (1) normal control, (2) diabetic control, and (3) diabetic rats which received diet containing 15% (w/w) of this mixture for 4 weeks. Diabetes was induced by intraperitoneal injection of streptozotocin (55 mg/kg). At the end of experiment, the mixture had no significant effect on serum hepatic enzymes, aspartate aminotransferase, and alanine aminotransferase activities. However, the level of fasting blood glucose, water intake, and urine output in treated group was lower than that in diabetic control rats (P<0.01). Also, the levels of triglyceride and total cholesterol in polyherbal mixture treated rats were significantly lower than those in diabetic control group (P<0.05). Our results demonstrated that this polyherbal mixture has beneficial effects on blood glucose and lipid profile and it has the potential to be used as a dietary supplement for the management of diabetes.

Ocimum sanctum L. is widely used as traditional remedy to manage hyperglycemia. This study was aimed to evaluate the effect of aqueous-methanolic extract of O. sanctum leaves (OSE) on the anti-diabetic activity of gliclazide in alloxan-induced diabetes in Wistar rats. Diabetes was induced by intraperitoneally injecting alloxan (120 mg/kg b.w.) in rats. Treatments including OSE (100 mg/kg b.w.), gliclazide (100 mg/kg b.w.), and in combination were given daily to diabetic rats till the 21st day of study. Body weight and fasting blood glucose levels were determined at regular intervals, while blood and organ samples were taken at the end of the study for biochemical and histopathological studies. Results showed that treatments exhibited anti-hyperglycemic activity through significantly (p [ 0.05) restoring body weight, fasting blood glucose level, and serum levels of glucose, insulin and HbA1c. The anti-lipidemic activity was noticed as total cholesterol (TC), triglyceride (TG), high-/low density-lipoproteins (HDL-C, LDL-C) levels were restored in treated diabetic rats. Ameliorative effects of treatments were observed as significant (p [ 0.05) reduction in serum levels of liver function biomarkers (alanine aminotransferase; ALT, aspartate aminotransferase; AST, alkaline phosphatase; ALP and bilirubin; BIL) and restoration of oxidative stress biomarkers (catalase; CAT, superoxide dismutase; SOD and malondialdehyde; MDA) in liver tissue. Histopathological findings supported these results as an increase in pancreatic islets size and protective effects on liver tissue was observed in diabetic rats treated with gliclazide and OSE alone and their combination. Conclusively, the combination of OSE and gliclazide produced a synergistic anti-diabetic effect as compared to that of alone treatment.
