The effect of Protein isolate from fermented melon seeds (Ogiri Protei Isolates; OPI) of Cucumeropsis manii on blood glucose, lipid profile, and antioxidant enzyme activities in streptozotocin (STZ)-induced diabetic rats was investigated. Thirty Male Wistar rats were divided into five equal groups. GThe first control group with no exposure. The second group of rats with Streptozotocin-induced non-treated diabetes. The 3rd and 4th groups of rats with Streptozotocin-induced diabetes supplemented with Ogiri protein isolates (200, 600 mg/kg in diet). And the 5th group of rats with Streptozotocin-induced diabetes administered glibenclamide in a dose 500 ug/kg in diet [17]. The OPI was administered for 6 weeks. The administration of OPI reduced the blood glucose concentration of the STZ-induced diabetic rats. Sera and hepatic superoxide dismutase, activities of the STZ-induced diabetic rats were significantly (P< 0.05) increased in comparison with the diabetic control rats. Lipid peroxidation of the supplemented OPI diabetic rats was significantly (P< 0.05) decreased in comparison with the diabetic control rats as the administration of OPI to the STZ-induced diabetic rats significantly increased the enzymes’ activities. The concentration of low-density lipoproteins in the OPI supplemented rats was significantly elevated. These data demonstrate that OPI supplements might be beneficial for correcting hyperglycemia but the consumption of OPI can modulate some tissue lipids in a direction not beneficial for CVD risk in patients with diabetes.

Objectives: This study investigated the antidiabetic and antihyperlipidemic potential of the ethanol extract of the leaves and stem of Cissus gracillis on alloxan monohydrate-induced diabetic albino rats. Methods: Preliminary phytochemical screening and acute toxicity were carried out. Animals were assigned into seven groups of five rats each. Groups A and B were administered 10 mg/kg each of glibenclamide and atorvastatin respectively, C, D, and E were given 125, 250 and 500 mg/kg of ethanol extract of C. gracillis, respectively, daily for 21 days through oral gavage, group F was diabetic but untreated (diabetic control group), while group G was non-diabetic and untreated which served as the control group. Results: Phytochemical screening revealed the presence of steroids/triterpenoids and carbohydrates. LD50 was above 5000 mg/kg. The extract at 500 mg/kg showed a statistically significant (p<0.05) decrease in blood glucose level when compared with the glibenclamide group on day 21. However, gradual non- significant reduction in blood glucose levels were observed in the extract treated groups on the 7th, 14th, and 21st days of treatment. The administration of ethanol extract of C. gracillis to alloxan-induced diabetic rats produced a decrease in total cholesterol, triglycerides, and low-density lipoproteins comparable to glibenclamide and atorvastatin. Conclusion: The ethanol extract of the leaves and stem of C. gracillis possess a mildly significant antidiabetic and antihyperlipidemic activity.

Objective: To determine the anti-hyperglycemic effects of interleukin-1 inhibitor (diacerein) in alloxan induced diabetic albino wistar rats. This experimental study was performed at the Department of Animal Husbandry and Veterinary Sciences, Sindh Agriculture University, Tando Jam within 6 months from April 2016 to September 2016. Total of 160 adult Albino Wistar Rats having an average of 200 to 300 grams body weights were selected. Animals were categorized into 4 groups as; Group A (n=15): Control rats – receive 0.9% normal saline as placebo Experimental Groups Group B (n=15): Experimental Control (Diabetic rats) - Alloxan50 mg/kg body weight intraperitoneal. Group C (n=15): Diabetic rats + Diacerein (30 mg/kg/day) orally daily. Group D (n=15): Diabetic rats + Diacerein (50 mg/kg/day) orally daily. Animals were kept and treated as per the NIH Guideline for Use and Care of Laboratory Animals. Diabetes mellitus was induced via a single intraperitoneal injection of 50 milligram/kg alloxan monohydrated dissolved in aseptic 0.9% saline. After 72 hours, blood specimens were taken from the caudal vein of the rats and glucose level>200 mg/dL was taken as diabetes. Experimental rats were given diacerein approximately 30 and 50 mg orally for 6 weeks. At the completion of experiment the body weight was measured of each animal by electronic measuring balance and blood sample was taken from each animal of all groups to assess the blood glucose level and HbA1c level. Data were recorded via self-made proforma and analysis was done by using SPSS version 20. Results: Average body weight of Diabetic control (Group B) was 193.33±22.50 grams, which was lower in contrast to Diacerein treated group C 202.47±25.70 grams and significantly lower as compared to Diacerein treated group D as  212.6±23.43 grams. A significant increase in blood glucose levels 182.07±10.63 mg/dl was noted in the Diabetic control (Group B) compared to Diacerein treated group C (110.13± 8.54 mg/dl) and group D (85.87±8.41 mg/dl) (P=0.001). HbA1c was markedly raised in the Group B- diabetic controls, while diacerein treated diabetic rats (groups C and D) showed a significant decrease in HbA1c (P=0.001). Conclusion: It was concluded that Diacerein achieves the Euglycemic state by reducing the levels of blood glucose and glycated hemoglobin (HbA1c) in Alloxan-Induced diabetes mellitus in Wistar Albino Rats.

Diabetes mellitus (DM) is the most common endocrine disorder of human. However, the anti-diabetic activity of protein isolates from fermented plants seed for DM remains enigmatic. The prevalence of diabetes in Africa is exponentially increasing with more deaths occurring directly from diabetes mellitus or from its associated complications. The current study investigated the effect of Protein isolate from fermented melon seeds (Ogiri; OPI) of Cucumeropsis manni on blood glucose, hepatic and pancreatic protein profile, histopathological parameters, identification and characterisation of expressed proteins in streptozotocin (STZ)-induced diabetic rats. Thirty Male wistar rats were divided into nondiabetic control, STZ-diabetic control, STZ-Ogiri protein isolate supplemented group (STZ-OPI; 200 mg/kg diet), STZ-Ogiri protein isolate supplemented group (STZ-OPI; 600 g/kg diet) and STZ-glibenclamide treated group (STZ-GBN; 0.5 mg/kg diet). Diabetes was induced by a single injection of STZ (60 mg/kg BW) freshly dissolved in 0.1 mol/L citrate buffer (pH 4.5) into the intraperitonium. Diabetes was confirmed by measuring the fasting blood glucose concentration 48-h post-injection. The rats with blood glucose level above 290 mg/dL were considered to be diabetic. Ogiri protein isolates was supplemented in the diet for 6 weeks. The supplementation OPI reduced (P< 0.05) the blood glucose concentration of the STZ-induced diabetic rats. OPI supplemented groups had significantly higher percentage body weight gain. The high dose OPI supplemented group had a lowest liver protein concentration (19.39 mg/dl) but a significantly (P< 0.05) higher pancreas protein concentration when compared to all the diabetic control. Histological sections of examined tissue revealed accumulation of fat in the liver of diabetic rats and necrosis of the islet of Langerhans were observed in the pancreas. 1DE SDS-PAGE of hepatic and pancreatic tissue homogenates revealed differential expression of 150 kDa proteins in rats treated with 200 mg/kg body weight of OPI only and 20-25 kDa proteins in rats treated with 600 mg/kg body weight of OPI respectively. This result show that OPI supplementation may impose a direct or indirect inhibitory or post translational modification on specific proteins implicated in hyperglycemia and diabetes and as such be a potential antihyperglycemic agent in the management of diabetes.

Aim: The current study observed the antidiabetic effect of Vasant Kusumakar Ras, an Ayurvedic polyherbal formulation, in alloxan-induced and dexamethasone-induced diabetic rats. Materials and Methods: Alloxan (120 mg/kg, i.p.) and dexamethasone sodium phosphate (5 mg/kg, i.p.) were used to induce diabetes in rats. The oral antidiabetic activity of Vasant Kusumakar Ras was evaluated by single doses of Vasant Kusumakar Ras (400 and 600 mg/kg, p.o.) in albino rats during a 10-day treatment period, with the effect of the Vasant Kusumakar Ras on blood glucose levels and serum lipid parameters measured on 0, 7th, and 11th day. Glibenclamide (5 mg/kg, p.o.) was used as the reference drug. Results: In alloxan-induced diabetic rats, the elevated levels of blood glucose significantly (p < 0.05) decreased after oral administration of Vasant Kusumakar Ras (400 mg/kg and 600 mg/kg), and Glibenclamide (5 mg/kg). When compared to the diabetic control group, treatment with Vasant Kusumakar Ras and Glibenclamide for 10 days reduced total cholesterol (TC) significantly (p < 0.001). Treatment with Vasant Kusumakar Ras and Glibenclamide for 10 days, significantly (p < 0.001) decreased low-density lipoprotein (LDL) level when compared to the diabetic control group. In dexamethasone-induced diabetic rats, all rats given with dexamethasone and Vasant Kusumakar Ras (400 mg/kg and 600 mg/kg) showed a significant (p < 0.05) decrease in the level of blood glucose when compared with diabetic control rats. The rats treated with dexamethasone and Glibenclamide showed a significant (p < 0.05) decrease in blood glucose level when compared to diabetic control rats. When compared to the diabetic control group, treatment with Vasant Kusumakar Ras and Glibenclamide (5 mg/kg) for 10 days reduced TC significantly (p < 0.001). Treatment with Vasant Kusumakar Ras and Glibenclamide for 10 days, significantly (p < 0.001) decreased LDL level when compared to the diabetic control group. Conclusion: Vasant Kusumakar Ras was shown to have significant antidiabetic activity comparable to that of glibenclamide and it also improves the lipid metabolism in both alloxan-induced and dexamethasone-induced diabetic rats.

Since the liver is among the primary organs susceptible to the effects of hyperglycaemia, diabetes mellitus (DM) could be a risk factor for the development and progression of liver damage. In present study, since no side-effects from the herbal medicine have been reported, the effect of silymarin on blood glucose concentration, hepatic histopathological changes and FOXA2 and FOXA3 gene expression, which are key genes in liver regeneration, was investigated. In this fundamental with experimental approach study, 40 male Wistar rats weighing 180-220 g were used. Rats were kept under the standard conditions of temperature of 20-22°C and humidity of 50% and consecutive 12-hour periods of light and darkness. Rats were randomly divided into five different groups (n=8 each), including healthy control rats, diabetic control rats, diabetic rats receiving silymarin (50, 100 and 150 mg/kg). Diabetes was induced by injecting streptozotocin (50 mg/kg B.W., i.p.). For 4 weeks silymarin groups received the drug once every three days through gavage and fasting blood glucose concentration measured once every 10 days. At the end of a month experiment, livers were harvested for hepatic histopathological and FOXA2 and FOXA3 gene expression changes analysis. In the diabetic rats treated with silymarin (50, 100 and 150 mg/kg), by comparison with the diabetic control group (p<0.05), glucose levels decreased significantly. Moreover, FOXA2 and FOXA3 expression in diabetic groups treated with silymarin significantly increased compared to diabetic control group (p<0.05). Hepatic histopathological changes were improved in the treated groups.The present study indicates that silymarin significantly decreased blood glucose concentration and increased the FOXA2 and FOXA3 gene products level. Hence, silymarin is able to improve some of the symptoms associated with diabetes and possesses hepatoprotective effects in streptozotocin-induced diabetic rats.

Citrullus vulgaris Schrad, commonly known as “watermelon” and Chrysophyllum albidum G., commonly called ‘‘Udara’’ are two important plants known to possess high antioxidant and therapeutic properties especially antidiabetic properties. The present study is aimed at investigating the blood glucose lowering potentials of both the aqueous and ethanolic extracts of the mixture of rinds of C. vulgaris Schrad and C. albidum in normal and alloxan-induced-diabetic rats. Aqueous and ethanol rinds extracts of the mixture were administered in wistar albino rats of weight range of 150-200g to determine their blood glucose lowering activity. The oral administration of aqueous mixed rinds extracts at dose of 1500 mg/kg body weight (Group 4) for 9 days led to a highly significant blood glucose reduction at P<0.05 when compared to the diabetic control (Group 2) and the ethanol mixed rinds extracts at the same dose (Group 6). There was a significant reduction in blood glucose (P<0.05) by other group dose extracts (Groups 3,5 and 6) compared to diabetic control. Hence, aqueous mixed rinds extracts of Citrullus vulgaris Schrad and C. albidum might be recommended as a potential hypoglycemic drug in the treatment of diabetes mellitus.
