Objective: In this study, we aimed to determine the effects of chromium picolinate (CrPic) on diabetes, one of the most common and fatal diseases in the world, and its associated oxidative damages.Methods: CrPic (100 μg/kg) and metformin (1000 mg/kg) were orally administered for 21 days in rats with nicotinamide + streptozotocin-induced Type 2 diabetes.Results: Significant decreases in fasting blood glucose levels were observed 14 days after initial administration in both CrPic (p<0.01) and metformin (p<0.001) groups compared with a diabetic control group (DC). Malondialdehyde (MDA) levels of all tissues were significantly higher in the DC group than in a normoglycemic control group (p<0.001). MDA levels of the CrPic group significantly decreased in heart (p<0.05) and liver (p<0.01) tissues. Glutathione (GSH) and catalase (CAT) levels in heart, kidney, and liver tissues increased in CrPic group (GSH p<0.001, p<0.05, and p<0.01; CAT p<0.001, p<0.001, and p<0.05, respectively). Superoxide dismutase enzyme levels significantly increased in CrPic group in the liver tissue (p>0.001), but no such changes were observed in heart and kidney tissues (p>0.05).Conclusion: The results obtained from this study indicate that CrPic may be effective in alleviating hyperglycemia and its consequent oxidative damage in experimental Type 2 diabetes.

Antidiabetic Effects

A model of type-2 diabetes mellitus (T2DM) using high-fat diet and low-dose STZ was established to assess the antidiabetic effects of Auricularia auricular polysaccharides simulated hydrolysates (AAPHs) obtained from the dried fruiting body of A. auricular. AAPHs were administered intragastrically (i.g.) at the dose of 0.15 g/kg b. W. to diabetic Wistar rats for 4 weeks. Results show that AAPHs was demonstrated to exhibit significant diminution in T-CHO and LDL-C levels (P < 0.05 or P < 0.01) compared to the diabetic control group. In addition, the secretion level of GLP-1 were different with the diabetes model group from 0 to 30 min, and had a tendency to alleviate weight loss. The current study suggests that AAPHs might be incorporated as a supplement in diabetic agents or combined with other health-care foods.

Background: Diabetes mellitus is a multifactorial metabolic disorder with several microvascular and macrovascular complications. Several plants have been used as dietary adjuvants to conventional drug therapy. Garcinia indica exhibits significant hypolipidemic and hypoglycemic activity. This study was conducted to evaluate the hypoglycemic effects of methanolic extract of seeds of Garcinia indica on blood glucose levels in Streptozotocin induced diabetic albino rats.Methods: Five groups of wistar albino rats (n=6) weighing 150-200g of either sex aged 3-4 months were obtained for the study. After overnight fasting, streptozotocin (50mg/kg) was administered intraperitoneally to induce diabetes. Five groups are: Group-1: Non diabetic control group, Group-2: diabetic control, Group-3: diabetic standard, Group-4: test group, Group-5: half of test + half of standard. Fasting blood sugar was estimated on 1, 3, 7, 14 and 28th day by capillary blood glucose method. The data obtained were subjected to statistical analysis.Results: In this study, following Streptozotocin administration the blood glucose levels increased in all groups on day 0. In group 2, blood glucose level gradually increased to 445.6±1.75mg/dl over a period of 4 weeks. Following glibenclamide administration in Group 3 - there was a gradual reduction in blood glucose levels: 269.8mg/dl - day 7 to 101.8mg/dl - week 4. Group 4 - persistent and significant (p<0.05) fall in blood glucose levels reaching upto 107mg/dl at the end of 4 weeks. Group 5 - 330mg/dl on day 1 which significantly (p<0.05) reduced to 101mg/dl on day 28. There was improvement in weight in group 4 and group 5 diabetic rats.Conclusions: The extract alone and in combination with glibenclamide showed significant hypoglycemic activity in comparison to diabetic control group.

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.

Background: Medicinal plants are now becoming indispensable in the treatment and management of many ailments. The unaffordability, unavailability and adverse effects of conventional therapy in the treatment and management of many diseases have geared keen interest in the use of herbal medicine. This work was carried out to investigate the prophylactic effect of the ethanol extract of Azadirachta indica leaf in streptozotocin-induced diabetic rats.   Methods: A total of one hundred (100) rats were randomized into four (4) groups (n=25) and used for the study. Each group of 25 rats was sub-divided into five (5) groups (n=5). The sub-groups comprise: Group A-normal control that was not treated, group B-100 mg/kg body weight of metformin and groups C to E - graded doses (100 mg/kg, 200 mg/kg and 400 mg/kg body weight) of the ethanol leaf extracts of A. indica leaves. The standard drug and the extracts were consecutively administered to groups B-E for 7, 14, 21 and 28 days before the induction of diabetes. Diabetes was induced intraperitoneally using 50 mg/kg bodyweight of streptozotocin. Results: The groups that were administered 100, 200 and 400 mg/kg bw of ethanol extract of A. indica showed a significant (p<0.05) increase in their weight after 21 and 28 days of pre-treatment compared with the control group that was not treated. The graded doses of the extract also have a remarkable effect in the fasting blood glucose levels which was made visible by the significant (p<0.05) reduction recorded in the fasting blood glucose levels compared with the control group that was not pre-treated and the group pre-treated with metformin. Conclusion: The results obtained in this research suggest that ethanol extract of A. indica has the potential to protect against diabetes by delaying its onset. However, the longer the period of pre-treatment, the better the condition of the animals pre-treated as well as the protection as can be seen from the results of the weight and fasting blood glucose levels.

4-((benzyloxy) amino)-2-hydroxy-4-oxobutanoic acid which is a succinamic acid derivative has been synthesized in 3 step reaction with malic acid. Its structure confirmation was done by various techniques like 1H NMR, 13C NMR, & HRMS and is recently proposed as an insulinotropic agent for the treatment of non-insulin dependent diabetes mellitus. In the present study, the effect of 4-((benzyloxy) amino)-2-hydroxy-4-oxobutanoic acid on plasma glucose, serum insulin, serum lipid profile and lipid peroxidation in streptozotocin–nicotinamide induced type 2 diabetic model was investigated.  4-((benzyloxy) amino)-2-hydroxy-4-oxobutanoic acid was administered orally (20 mg/kg b.w.) to streptozotocin + nicotinamide (STZ + NAD) induced diabetic rats for 28 days. A significant increase in fasting blood glucose levels, HbA1c levels, Serum lipid profile (TG & TC) and in  the levels of Malonaldialdehyde (MDA, end product of lipid peroxidation) was observed in STZ +NAD diabetic rats whereas the levels of high density lipoprotein-cholesterol (HDL-C) and serum insulin levels were significantly decreased  in STZ + NAD induced diabetic rats The effect of 4-((benzyloxy)amino)-2-hydroxy-4-oxobutanoic acid was compared with glibenclamide, a reference drug. Treatment with 4-((benzyloxy) amino)-2-hydroxy-4-oxobutanoic acid and glibenclamide resulted in a significant reduction of fasting blood glucose levels with increase in plasma insulin levels in diabetic treated rats. 4-((benzyloxy) amino)-2-hydroxy-4-oxobutanoic acid also resulted in a significant improvement in serum lipids and lipid peroxidation products. Our results suggest the potential role of 4-((benzyloxy) amino)-2-hydroxy-4-oxobutanoic acid in the management of type-2 diabetes mellitus experimental rats.

The methanolic leaf extract of Vernonia amygdalina (MLVA) was assessed to evaluate its antidiabetic potential in rats. Diabetes was induced in male Wistar rats by the administration of alloxan monohydrate at 100 mg/kg of body weight. After 48 h, rats with fasting blood glucose levels of 200 mg/dL and above were considered diabetic and used for the study. The experimental animals were grouped into five groups (A–E) of 10 animals each. Group A rats were non-diabetic normal control, Group B consisted of diabetic control rats that received no treatment, groups C, D and E rats were diabetic rats but treated with glibenclamide, 200 and 400 mg/kg doses of MLVA respectively. Blood samples were collected at days 14 and 28 after induction for haematological and serum biochemical indices such as triglycerides, LDL, cholesterols etc. The intestine was collected and intestinal homogenate was prepared for the antioxidant studies. The extract at 200 mg/kg and 400 mg/kg doses significantly (p < 0.05) reduced blood glucose levels in extract-treated diabetic rats and also significantly increased weight gain in these rats. Most haematological parameters in treated rats experienced, while platelets and neutrophils were decreased. Biochemical indices measured were reduced in MLVA-treated groups compared with diabetic control. Treatment with MLVA also produced significant (p < 0.05) decrease in markers of oxidative stress but increased levels of enzymic and non-enzymic antioxidant markers in intestinal homogenates of treated groups compared with diabetic control. This study showed that V. amygdalina has antihyperglycaemic and in vivo antioxidant effects.

The purpose of this study was to investigate whether smeathxanthone A isolated from Garcinia smeathmaniiimproves incisional wound healing in diabetic mice. Male albino alloxan-induced diabetic mice (n= 20) were divided into five groups: normal control, diabetic control, 2.5 mg/kg glibenclamide given orally, 0.05 and 0.1 mg/kg smeathxanthone A given subcutaneously. Animals were euthanized on postoperative day 10 after wounding; body weight, blood glucose, breaking strength, and histologic examination were reviewed. Smeathxanthone A significantly increased skin tensile strength (24% higher than diabetic control group when given at 0.1 mg/kg), stimulated hair growth, and reduced signs of inflammation in the scar sections. Smeathxanthone A also reduced blood glucose levels in diabetic mice (45% higher than diabetic control group when given at 0.1 mg/kg). The present study demonstrates that administration of smeathxanthone A after laparotomy expedites wound healing in mice. We suggest that it could confer benefits to tissue healing by significantly enhancing tissue collagen deposition and controlling blood glucose levels.
